Introducing Cruz: An AI Data Engineer In-a-Box

Why we built it and what it does

Artificial Intelligence is perceived as a panacea for modern business challenges with its potential to unlock greater efficiency, enhance decision-making, and optimize resource allocation. However, today’s commercially-available AI solutions are reactive – they assist, enhance analysis, and bolster detection, but don’t act on their own. With the explosion of data from cloud applications, IoT devices, and distributed systems, data teams are burdened with manual monitoring, complex security controls, and fragmented systems that demand constant oversight. What they really need is more than an AI copilot, but a complementary data engineer that takes over all the exhausting work and freeing them up for more strategic data and security work.

That’s where we saw an opportunity. The question that inspired us: How do we transform the way organizations approach data management? The answer led us to Cruz—not just another AI tool, but an autonomous AI data engineer that monitors, detects, adapts, and actively resolves issues with minimal human intervention.

Why We Built Cruz

Organizations face unprecedented challenges in managing vast amounts of data across multiple systems. From integration headaches to security threats, data engineers and security teams are under immense pressure to keep pace with evolving data risks. These challenges extend beyond mere volume—they strike at the effectiveness, security, and real-time insight generation.

  1. Integration Complexity

Data ecosystems are expanding, encompassing diverse tools and platforms—from SIEMs to cloud infrastructure, data lakes, and observability tools. The challenge lies in integrating these disparate systems to achieve unified visibility without compromising security or efficiency. Data teams often spend days or even weeks developing custom connections, which then require continuous monitoring and maintenance.

  1. Disparate Data Formats

Data is generated in varied formats—from logs and alerts to metrics and performance data—making it difficult to maintain quality and extract actionable insights. Compounding this challenge, these formats are not static; schema drifts and unexpected variations further complicate data normalization.

  1. The Cost of Scaling and Storage

With data growing exponentially, organizations struggle with storage, retrieval, and analysis costs. Storing massive amounts of data inflates SIEM and cloud storage costs, while manually filtering out data without loss is nearly impossible. The challenge isn’t just about storage—it’s about efficiently managing data volume while preserving essential information.

  1. Delayed and Inconsistent Insights

Even after data is properly integrated and parsed, extracting meaningful insights is another challenge. Overwhelming volumes of alerts and events make it difficult for data teams to manually query and review dashboards. This overload delays insights, increasing the risk of missing real-time opportunities and security threats.

These challenges demand excessive manual effort—updating normalization, writing rules, querying data, monitoring, and threat hunting—leaving little time for innovation. While traditional AI tools improve efficiency by automating basic tasks or detecting predefined anomalies, they lack the ability to act, adapt, and prioritize autonomously.

What if AI could do more than assist? What if it could autonomously orchestrate data pipelines, proactively neutralize threats, intelligently parse data, and continuously optimize costs? This vision drove us to build Cruz to be an AI system that is context-aware, adaptive, and capable of autonomous decision-making in real time.

Cruz as Agentic AI: Informed, Perceptive, Proactive

Traditional data management solutions are struggling to keep up with the complexities of modern enterprises. We needed a transformative approach—one that led us to agentic AI. Agentic AI represents the next evolution in artificial intelligence, blending sophisticated reasoning with iterative planning to autonomously solve complex, multi-step problems. Cruz embodies this evolution through three core capabilities: being informed, perceptive, and proactive.

Informed Decision-Making

Cruz leverages Retrieval-Augmented Generation (RAG), to understand complex data relationships and maintain a holistic view of an organization’s data ecosystem. By analyzing historical patterns, real-time signals, and organizational policies, Cruz goes beyond raw data analysis to make intelligent, autonomous decisions enhancing efficiency and optimization.

Perceptive Analysis

Cruz’s perceptive intelligence extends beyond basic pattern detection. It recognizes hidden correlations across diverse data sources, differentiates between routine fluctuations and critical anomalies, and dynamically adjusts its responses based on situational context. This deep awareness ensures smarter, more precise decisions without requiring constant human intervention.

Proactive Intelligence

Rather than waiting for issues to emerge, Cruz actively monitors data environments, anticipating potential challenges before they impact operations. It identifies optimization opportunities, detects anomalies, and initiates corrective actions autonomously while continuously evolving to deliver smarter and more effective data management over time.

Redefining Data Management with Autonomous Intelligence

Modern data environments are complex and constantly evolving, requiring more than just automation. Cruz’s agentic capabilities redefine how organizations manage data by autonomously handling tasks traditionally consuming significant engineering time. For example, when schema drift occurs, traditional tools may only alert administrators, but Cruz autonomously analyzes the data pattern, identifies inconsistencies, and updates normalization in real-time.

Unlike traditional tools that rely on static monitoring, Cruz actively scans your data ecosystem, identifying threats and optimization opportunities before they escalate. Whether it's streamlining data flows, transforming data, or reducing data volume, Cruz executes these tasks autonomously while ensuring data integrity.

Cruz's Core Capabilities

  • Plug and Play Integration: Cruz automatically discovers data sources across cloud and on-prem environments, providing a comprehensive data overview. With a single click, Cruz streamlines what would typically be hours of manual setup into a fast, effortless process, ensuring quick and seamless integration with your existing infrastructure.
  • Automated Parsing: Where traditional tools stop at flagging issues, Cruz takes the next step. It proactively parses, normalizes, and resolves inconsistencies in real time. It autonomously updates schemas, masks sensitive data, and refines structures—eliminating days of manual engineering effort.
  • Real-time AI-driven Insights: Cruz leverages advanced AI capabilities to provide insights that go far beyond human-scale analysis. By continuously monitoring data patterns, it provides real-time insights into performance, emerging trends, volume reduction opportunities, and data quality enhancements, enabling better decision-making and faster data optimization.
  • Intelligent Volume Reduction: Cruz actively monitors data environments to identify opportunities for volume reduction by analyzing patterns and creating rules to filter out irrelevant data. For example, it identifies irrelevant fields in logs sent to SIEM systems, eliminating data that doesn't contribute to security insights. Additionally, it filters out duplicate or redundant data, minimizing storage and observability costs while maintaining data accuracy and integrity.
  • Automating Analytics: Cruz operates 24/7, continuously monitoring and analyzing data streams in real-time to ensure no insights are missed. With deep contextual understanding, it detects patterns, anticipates potential threats, and uncovers optimization. By automating these processes, Cruz saves engineering hours, minimizes human errors, and ensures data remains protected, enriched, and readily available for actionable insights.

Conclusion

Cruz is more than an AI tool—it’s an AI Data Engineer that evolves with your data ecosystem, continuously learning and adapting to keep your organization ahead of data challenges. By automating complex tasks, resolving issues, and optimizing operations, Cruz frees data teams from the burden of constant monitoring and manual intervention. Instead of reacting to problems, organizations can focus on strategy, innovation, and scaling their data capabilities.

Alert Fatigue Cybersecurity: Why Your Security Alerts Should Work Smarter — Not Just Harder

Security teams today are truly feeling alert fatigue in cybersecurity. Legacy SIEMs and point tools spit out tons of notifications, many of them low-priority or redundant. Analysts are often overwhelmed by a noisy tsunami of alerts from outdated pipelines. When critical alerts are buried under a flood of false positives, they can easily be missed — sometimes until it’s too late. The result is exhausted analysts, blown budgets, and dangerous gaps in protection. Simply throwing more alerts at the wall won’t help. Instead, alerting must become smarter and integrated across the entire data flow.

Traditional alerting is breaking under modern scale. Today’s SOCs juggle dozens of tools and 50–140 data sources (source). Each might generate its own alarms. Without a unified system, these silos create confusion and operational blind spots. For example, expired API credentials or a collector crash can stop log flows entirely, with no alarms triggered until an unrelated investigation finally uncovers the gap. Even perfect detection rules don’t fire if the logs never make it in or are corrupted silently.

Traditional monitoring stacks often leave SOCs blind. Alert fatigue in cybersecurity is built on disconnected alerts from devices, collectors, and analytic tools that create noise and gaps. For many organizations, visibility is the problem: thousands of devices and services are producing logs, but teams can’t track their health or data quality. Static inventories mean unknown devices slip through the cracks; unanalyzed logs clog the system. Siloed alert pipelines only worsen this. For instance, a failed log parser may simply drop fields silently — incident response only discovers it later when dashboards go dark. By the time someone notices a broken widget, attackers may have been active unnoticed.

Cybersecurity alert fatigue is part of this breakdown. Analysts bombarded with hundreds of alerts per hour inevitably become desensitized. Time spent investigating low-value alarms is time not spent on real incidents. Diverting staff to chasing trivial alerts directly worsens MTTD (Mean Time to Detect) and MTTR (Mean Time to Respond) for genuine threats. In practice, studies show most organizations struggle to keep up — 70% say they can’t handle their alert volume (source). The danger is that attacks or insider issues silently slip by under all that noise. In short, fragmented alerting slows response and increases risk rather than preventing it.

Key Benefits of Intelligent Security Alerting

Implementing an intelligent, unified alerting framework brings concrete benefits:

  • Proactive Problem Detection: The pipeline itself warns you of issues before they cascade. You get early warnings of device outages, schema changes, or misconfigurations. This allows fixes before a breach or compliance incident. With agentic AI built in, the system can even auto-correct minor errors – a schema change might be handled on the fly.
  • Reduced Alert Noise: By filtering irrelevant events and deduplicating correlated alerts, teams see far fewer unnecessary notifications. Databahn has observed that clean pipeline controls can cut downstream noise by over 50% [(internal observation)].
  • Faster Incident Resolution: With related alerts grouped and context included, security and dev teams diagnose problems faster. Organizations see significantly lower MTTR when using alert correlation. Databahn’s customers, for example, report roughly 40% faster troubleshooting after turning on their smart pipeline features [(internal customer feedback)].
  • Full Operational Clarity: A single, integrated dashboard shows pipeline health end-to-end. You always know which data sources and agents are active, healthy, or in error. This “complete operational picture” provides situational awareness that fragmented tools cannot. When an alert fires, you instantly see where it originated and how it affects downstream flows.
  • Scalability and Resilience: Intelligent alerting scales with your environment. It works across hybrid clouds, edge deployments, and thousands of devices. Because the framework governs itself, it is easier to maintain as data volumes grow. In practice, teams gain confidence that their data feeding alerts and reports is reliable, not full of unseen gaps.

By bringing these advantages together, unified alerting can truly change the game. Security teams are no longer scrambling to stitch together disconnected signals; instead, they operate on real-time, actionable intelligence. In one customer implementation, unified alerting led to a 50% reduction in alert noise and 40% improvement in mean time to resolution (source).

Real-World Impact: Catching  Alert Fatigue Cybersecurity Early

The power of smarter alerts is best seen in examples:

  • Silent Log Outage: Suppose a critical firewall’s logging stops overnight due to an expired API key. In a legacy setup, this might only be noticed days later, when analysts see a gap in the SIEM dashboards. By then, an attacker might have slipped through during the silent hours. With a unified pipeline, the moment log volume drops unexpectedly the system sends an alert (e.g. a 10% volume discrepancy). The Ops team can intervene immediately, preventing data loss at the source.
  • Parser or Schema Failure: A vendor’s log format changes with new fields or values. Traditional pipelines might silently skip the unknown fields, causing some detections to fail without warning. Analysts only discover the problem much later, when investigating an unrelated incident. An intelligent alerting system, however, recognizes the change. It may mark the schema as “evolving” and notify the team or even auto-update the parser.
  • Connector/Agent Fleet Issue: Imagine a batch of endpoints fails to forward logs due to a faulty update. Instead of ten separate alerts, a unified system issues a single correlated event (“Agent fleet offline”) with details on which hosts. This drastically reduces noise and focuses effort.
  • Data Discrepancy: A data routing failure causes only half the logs to reach the SIEM. A smart pipeline can detect the mismatch right away by comparing expected vs. actual event counts and alerting if the difference exceeds a threshold. In practice, this means catching data loss at the source instead of noticing it in a broken dashboard.

These real-world examples show how alerting should work: catching the problem upstream, with clear context. Detection engineering is only as strong as your data pipeline. If the pipeline fails, your alerts fail too. Robust monitoring of the pipeline itself is therefore as critical as detection rules.

Conclusion: Modernizing Alerts for Scale and Reliability

The way forward is clear: don’t just add more alerts, get smarter about them. Modern SOCs need an alerting framework that is integrated, intelligent, and end-to-end. That means covering every part of your data pipeline — from device agents to analytics — under a single umbrella. It means correlating related events and routing them to the right people. And it means proactive, AI-driven checks so that problems are fixed before they cause trouble.

The payoff is huge. With unified alerting, security teams gain faster detection of real issues, fewer distractions from noise, and dramatic reductions in troubleshooting time. This approach yields fewer outages, faster recovery, and operational clarity. In other words, it helps SOCs scale safely and keep up with today’s complex environments.

Work smarter, not harder. By modernizing your alert pipelines, you turn alerting from an endless chore into a true force multiplier — empowering your team to focus on what really matters.

For more than a decade, a handful of technical giants have been the invisible gravity that holds the digital world together. Together, they power over half of the world’s cloud workloads with Amazon S3 alone peaking at nearly 1 petabyte per second in bandwidth. With average uptimes measured at 99.999% and data centers spanning every continent, these clouds have made reliability feel almost ordinary.

When you order a meal, book a flight, or send a message, you don’t wonder where the data lives. You expect it to work – instantly, everywhere, all the time. That’s the brilliance, and the paradox, of hyperscale computing: the better it gets, the less we remember it’s there.

So, when two giants falter, the world didn’t just face downtime – it felt disconnected from its digital heartbeat. Snapchat went silent. Coinbase froze. Heathrow check-ins halted. Webflow  blinked out.

And Meredith Whittaker, the President of Signal, reminded the internet in a now-viral post, “There are only a handful of entities on Earth capable of offering the kind of global infrastructure a service like Signal requires.”  

She’s right, and that’s precisely the problem. If so much of the world runs on so few providers, what happens when the sky blinks?  

In this piece, we’ll explore what the recent AWS and Azure outages teach us about dependency, and why multi-cloud resilience may be the only way forward. And how doing it right requires re-thinking how enterprises design for continuity itself.

Why even the most resilient systems go down

For global enterprises, only three cloud providers on the planet – AWS, Azure, and Google Cloud – offer true global reach with the compliance, scale, and performance demanded by millions of concurrent users and devices.

Their dominance wasn’t luck; it was engineered. Over the past decade, these hyperscalers built astonishingly resilient systems with unmatched global reach, distributing workloads across regions, synchronizing backups between data centers, and making downtime feel mythical.

As these three providers grew, they didn’t just sell compute – they sold confidence. The pitch to enterprises was simple: stay within our ecosystem, and you’ll never go down. To prove it, they built seamless multi-region replication, allowing workloads and databases to mirror across geographies in real time. A failover in Oregon could instantly shift to Virginia; a backup in Singapore could keep services running if Tokyo stumbled. Multi-region became both a technological marvel and a marketing assurance – proof that a single-cloud strategy could deliver global continuity without the complexity of managing multiple vendors.  

That’s why multi-region architecture became the de facto safety net. Within a single cloud system, creating secondary zones and failover systems was a simple, cost-effective, and largely automated process. For most organizations, it was the rational resilient architecture. For a decade, it worked beautifully.

Until this October.

The AWS and Azure outages didn’t start in a data center or a regional cluster. They began in the global orchestration layers – the digital data traffic control systems that manage routing, authentication, and coordination across every region. When those systems blinked, every dependent region blinked with them.

Essentially, the same architecture that made cloud redundancy easy also created a dependency that no customer of these three service providers can escape. As Meredith Whittaker added in her post, “Cloud infrastructure is a choke point for the entire digital ecosystem.

Her words capture the uncomfortable truth that the strength of cloud infrastructure – its globe-straddling, unifying scale – has become its vulnerability. Control-plane failures have happened before, but they were rare enough and systems recovered fast enough that single-vendor, multi-region strategies felt sufficient. The events of October changed that calculus. Even the global scaffolding of these global cloud providers can falter – and when it does, no amount of intra-cloud redundancy can substitute for independence.

If multi-region resilience can no longer guarantee uptime, the next evolution isn’t redundancy; it is reinvention. Multi-cloud resilience – not as a buzzword, but as a design discipline that treats portability, data liquidity, and provider-agnostic uptime as first-class principles of modern architecture.

Multi-cloud is the answer – and why it’s hard

For years, multi-cloud has been the white whale of IT strategy – admired from afar, rarely captured. The premise was simple: distribute workloads across providers to minimize risk, prevent downtime, and avoid over-reliance on a single vendor.

The challenge was never conviction – it was complexity. Because true multi-cloud isn’t just about having backups elsewhere – it’s about keeping two living systems in sync.

Every transaction, every log, every user action must decide: Do I replicate this now or later? To which system? In what format? When one cloud slows or fails, automation must not only redirect workloads but also determine what state of data to recover, when to switch back, and how to avoid conflicts when both sides come online again.

The system needs to determine which version of a record is authoritative, how to maintain integrity during mid-flight transactions, and how to ensure compliance when one region’s laws differ from those of another. Testing these scenarios is notoriously difficult. Simulating a global outage can disrupt production; not testing leaves blind spots.

This is why multi-cloud used to be a luxury reserved for a few technology giants with large engineering teams. For everyone else, the math – and the risk – didn’t work.

Cloud’s rise, after all, was powered by convenience. AWS, Azure, and Google Cloud offered a unified ecosystem where scale, replication, and resilience were built in. They let engineering teams move faster by outsourcing undifferentiated heavy lifting – from storage and security to global networking. Within those walls, resilience felt like a solved problem.

Due to this complexity and convenience, single-vendor multi-region architectures have become the gold standard. They were cost-effective, automated, and easy to manage. The architecture made sense – until it didn’t.

The October outages revealed the blind spot. And that is where the conversation shifts.
This isn’t about distrust in cloud vendors – their reliability remains extraordinary. It’s about responsible risk management in a world where that reliability can no longer be assumed as absolute.

Forward-looking leaders are now asking a new question:
Can emerging technologies finally make multi-cloud feasible – not as a hedge, but as a new standard for resilience?

That’s the opportunity. To transform what was once an engineering burden into a business imperative – to use automation, data fabrics, and AI-assisted operations to not just distribute workloads, but to create enterprise-grade confidence.

The Five Principles of true multi-cloud resilience

Modern enterprises don’t just run on data: they run on uninterrupted access to it.
In a world where customers expect every transaction, login, and workflow to be instantaneous, resilience has become the most accurate measure of trust.

That’s why multi-cloud matters. It’s the only architectural model that promises “always-up” systems – platforms capable of staying operational even when a primary cloud provider experiences disruption. By distributing workloads, data, and control across multiple providers, enterprises can insulate their business from global outages and deliver the reliability their customers already expect to be guaranteed. It would put enterprises back in the driver’s seat on their systems, rather than leaving them vulnerable to provider failures.

The question is no longer whether multi-cloud is desirable, but how it can be achieved without increasing complexity to the extent of making it unfeasible. Enterprises that succeed tend to follow five foundational principles – pragmatic guardrails for transforming resilience into a lasting architecture.

  1. Start at the Edge: Independent Traffic Control
    Resilience begins with control over routing. In most single-cloud designs, DNS, load balancing, and traffic steering live inside the provider’s control plane – the very layer that failed in October. A neutral, provider-independent edge – using external DNS and traffic managers – creates a first line of defense. When one cloud falters, requests can automatically shift to another entry point in seconds.
  1. Dual-Home Identity and Access
    Authentication outages often outlast infrastructure ones. Enterprises should maintain a secondary identity and secrets system – an auxiliary OIDC or SAML provider, or escrowed credentials – that can mint and validate tokens even if a cloud’s native IAM or Entra service goes dark.
  1. Make Data Liquid
    Data is the most complex system to move and the easiest to lose. True multi-cloud architecture treats data as a flowing asset, not as a static store. This means continuous replication across providers, standardized schemas, and automated reconciliation to keep operational data within defined RPO/RTO windows. Modern data fabrics and object storage replication make this feasible without doubling costs. AI-powered data pipelines can also provide schema standardization, indexing, and tagging at the point of ingesting, and prioritizing, routing, duplicating, and routing data with granular policy implementation with edge governance.
  1. Build Cloud-agnostic Application Layers
    Every dependency on proprietary PaaS services – queues, functions, monitoring agents – ties resilience to a single vendor. Abstracting the application tier with containers, service meshes, and portable frameworks ensures that workloads can be deployed or recovered anywhere, providing flexibility and scalability. Kubernetes, Kafka, and open telemetry stacks are not silver bullets, but they serve as the connective tissue of mobility.  
  1. Govern for Autonomy, not Abandonment
    Multi-cloud isn’t about rejecting providers; it is about de-risking dependence. That requires unified governance – visibility, cost control, compliance, and observability – that transcends vendor dashboards. Modern automation and AI-assisted orchestration can maintain policy consistency across environments, ensuring resilience without becoming operational debt.  

When these five principles converge, resilience stops being reactive and becomes a design property of the enterprise itself. It turns multi-cloud from an engineering aspiration into a business continuity strategy – one that keeps critical services available, customer trust intact, and the brand’s promise uninterrupted.

From pioneers to the possible

Not long ago, multi-cloud resilience was a privilege reserved for the few – projects measured in years, not quarters.

Coca-Cola began its multi-cloud transformation around 2017, building a governance and management system that could span AWS, Azure, and Google Cloud. It took years of integration and cost optimization for the company to achieve unified visibility across its environments.

Goldman Sachs followed, extending its cloud footprint from AWS into Google Cloud by 2019, balancing trading workloads on one platform with data analytics and machine learning on another. Their multi-cloud evolution unfolded gradually through 2023, aligning high-performance finance systems with specialized AI infrastructure.

In Japan, Mizuho Financial Group launched its multi-cloud modernization initiative in 2020, achieving strict financial-sector compliance while reducing server build time by nearly 80 percent by 2022.

Each of these enterprises demonstrated the principle: true continuity and flexibility are possible, but historically only through multi-year engineering programs, deep vendor collaboration, and substantial internal bandwidth.

That equation is evolving. Advances in AI, automation, and unified data fabrics now make the kind of resilience these pioneers sought achievable in a fraction of the time – without rebuilding every system from scratch.

Modern platforms like Databahn represent this shift, enabling enterprises to seamlessly orchestrate, move, and analyze data across clouds. They transform multi-cloud from merely an infrastructure concern into an intelligence layer – one that detects disruptions, adapts automatically, and keeps the enterprise operational even when the clouds above encounter issues.

Owning the future: building resilience on liquid data

Every outage leaves a lesson in its wake. The October disruptions made one thing unmistakably clear: even the best-engineered clouds are not immune to failure.
For enterprises that live and breathe digital uptime, resilience can no longer be delegated — it must be designed.

And at the heart of that design lies data. Not just stored or secured, but liquid – continuously available, intelligently replicated, and ready to flow wherever it’s needed.
Liquid data powers cross-cloud recovery, real-time visibility, and adaptive systems that think and react faster than disruptions.

That’s the future of enterprise architecture: always-on systems built not around a single provider, but around intelligent fabrics that keep operations alive through uncertainty.
It’s how responsible leaders will measure resilience in the next decade – not by the cloud they choose, but by the continuity they guarantee.

At Databahn, we believe that liquid data is the defining resource of the 21st century –  both the foundation of AI and the reporting layer that drives the world’s most critical business decisions. We help enterprises control and own their data in the most resilient and fault-tolerant way possible.

What is a SIEM?

A Security Information and Event Management (SIEM) system aggregates logs and security events from across an organization’s IT infrastructure. It correlates and analyzes data in real time, using built-in rules, analytics, and threat intelligence to identify anomalies and attacks as they happen. SIEMs provide dashboards, alerts, and reports that help security teams respond quickly to incidents and satisfy compliance requirements. In essence, a SIEM acts as a central security dashboard, giving analysts a unified view of events and threats across their environment.

Pros and Cons of SIEM

Pros of SIEM:

  • Real-time monitoring and alerting for known threats via continuous data collection
  • Centralized log management provides a unified view of security events
  • Built-in compliance reporting and audit trails simplify regulatory obligations
  • Extensive integration ecosystem with standard enterprise tools
  • Automated playbooks and correlation rules accelerate incident triage and response

Cons of SIEM:

  • High costs for licensing, storage, and processing at large data volumes
  • Scalability issues often require filtering or short retention windows
  • May struggle with cloud-native environments or unstructured data without heavy customization
  • Requires ongoing tuning and maintenance to reduce false positives
  • Vendor lock-in due to proprietary data formats and closed architectures

What is a Security Data Lake?

A security data lake is a centralized big-data repository (often cloud-based) designed to store and analyze vast amounts of security-related data in its raw form. It collects logs, network traffic captures, alerts, endpoint telemetry, threat intelligence feeds, and more, without enforcing a strict schema on ingestion. Using schema-on-read, analysts can run SQL queries, full-text searches, machine learning, and AI algorithms on this raw data. Data lakes can scale to petabytes, making it possible to retain years of data for forensic analysis.

Pros and Cons of Security Data Lakes

Pros of Data Lakes:

  • Massive scalability and lower storage costs, especially with cloud-based storage
  • Flexible ingestion: accepts any data type without predefined schema
  • Enables advanced analytics and threat hunting via machine learning and historical querying
  • Breaks down data silos and supports collaboration across security, IT, and compliance
  • Long-term data retention supports regulatory and forensic needs

Cons of Data Lakes:

  • Requires significant data engineering effort and strong data governance
  • Lacks native real-time detection—requires custom detections and tooling
  • Centralized sensitive data increases security and compliance challenges
  • Integration with legacy workflows and analytics tools can be complex
  • Without proper structure and tooling, can become an unmanageable “data swamp”  

A Hybrid Approach: Security Data Fabric

Rather than choosing one side, many security teams adopt a hybrid architecture that uses both SIEM and data lake capabilities. Often called a “security data fabric,” this strategy decouples data collection, storage, and analysis into flexible layers. For example:

  • Data Filtering and Routing: Ingest all security logs through a centralized pipeline that tags and routes data. Send only relevant events and alerts to the SIEM (to reduce noise and license costs), while streaming raw logs and enriched telemetry to the data lake for deep analysis.
  • Normalized Data Model: Preprocess and normalize data on the way into the lake so that fields (timestamps, IP addresses, user IDs, etc.) are consistent. This makes it easier for analysts to query and correlate data across sources.
  • Tiered Storage Strategy: Keep recent or critical logs indexed in the SIEM for fast, interactive queries. Offload bulk data to the data lake’s cheaper storage tiers (including cold storage) for long-term retention. Compliance logs can be archived in the lake where they can be replayed if needed.
  • Unified Analytics: Let the SIEM focus on real-time monitoring and alerting. Use the data lake for ad-hoc investigations and machine-learning-driven threat hunting. Security analysts can run complex queries on the full dataset in the lake, while SIEM alerts feed into a coordinated response plan.
  • Integration with Automation: Connect the SIEM and data lake to orchestration/SOAR platforms. This ensures that alerts or insights from either system trigger a unified incident response workflow.

This modular security data fabric is an emerging industry best practice. It helps organizations avoid vendor lock-in and balance cost with capability. For instance, by filtering out irrelevant data, the SIEM can operate leaner and more accurately. Meanwhile, threat hunters gain access to the complete historical dataset in the lake.

Choosing the Right Strategy

Every organization’s needs differ. A full-featured SIEM might be sufficient for smaller environments or for teams that prioritize quick alerting and compliance out-of-the-box. Large enterprises or those with very high data volumes often need data lake capabilities to scale analytics and run advanced machine learning. In practice, many CISOs opt for a combined approach: maintain a core SIEM for active monitoring and use a security data lake for additional storage and insights.

Key factors include data volume, regulatory requirements, budget, and team expertise. Data lakes can dramatically reduce storage costs and enable new analytics, but they require dedicated data engineering and governance. SIEMs provide mature detection features and reporting, but can become costly and complex at scale. A hybrid “data fabric” lets you balance these trade-offs and future-proof the security stack.

At the end of the day, rethinking SIEM doesn’t necessarily mean replacing it. It means integrating SIEM tools with big-data analytics in a unified way. By leveraging both technologies — the immediate threat detection of SIEM and the scalable depth of data lakes — security teams can build a more flexible, robust analytics platform.
