The Reveal Platform
In the age of big data, connections are everywhere, but raw links alone can’t save us from chaos. Like a machine without a mission, traditional link analysis maps relationships yet misses their meaning. The real transformation begins when context, identity, and correlation step into the spotlight. This is the rise of a new era, where every link tells a story, every node has a purpose, and intelligence becomes actionable. The question isn’t whether you can see the network; it’s whether you can understand it before the next judgment day.
Security telemetry is everywhere — identity logs, endpoint activity, cloud audit trails, network flows, application events, EDR signals, and more. But here’s the hard truth: security data that isn’t correlated back to real users and entities is just noise.
The real challenge for modern SOC teams isn’t collecting logs. It’s understanding who did what, when, how it connects across systems, and why it matters — fast enough to stop threats before damage occurs. That’s where link analysis is critical.
Gurucul’s Next-Gen SIEM was purpose-built to solve this challenge by operationalizing advanced, identity-driven link analysis that powers UEBA at machine speed and scale.
Traditional SIEMs were designed for a simpler time — one where static infrastructure, predictable identities, and isolated attacks were the norm. That model no longer works.
Most legacy SIEMs treat logs as isolated records. Analysts are forced to manually pivot between usernames, hostnames, IPs, device IDs, and cloud identifiers just to understand a single incident.
The result:
Instead of seeing behavior, analysts see fragments.
Traditional correlation focuses on obvious fields like hostname or username. But modern environments are dynamic and now include GenAI-driven identities and machine accounts, introducing additional complexity.
Static, rule-based correlation can’t keep up with attacks that pivot across systems and identities in hours — not weeks.
UEBA without link analysis lacks depth. When activity isn’t tied to consistent identities, roles, peer groups, and history, behavioral models generate:
Without linkage, UEBA detects anomalies — but lacks the context and correlation needed to assess the risk and relevance.
Gurucul’s link analysis goes far beyond simple joins. The platform builds a rich identity and entity graph that connects users, devices, applications, and infrastructure into a unified behavioral narrative.
Gurucul correlates security telemetry from:
All activity is linked back to distinct users and entities, even when identifiers differ across sources—usernames, email addresses, device IDs, API tokens, or cloud-native IDs. This identity-first approach gives analysts a complete, historical activity timeline for each user or entity, revealing real behavior patterns rather than isolated alerts.
Correlation alone isn’t enough. Analysts need contextual insight to understand what an activity means in business terms quickly. Gurucul’s Investigate search experience enhances raw logs by revealing unique analytical attributes related to the activity being investigated, such as:
For example:
This capability enables analysts to quickly understand the business context, dramatically improving triage speed and investigation accuracy.
Gurucul’s link analysis extends far beyond simple field matching. Using lookup tables (feeds) and API-driven enrichment, the platform enables multi-hop correlation across disparate systems.
For example:
This enables correlation paths that legacy SIEMs cannot perform—linking identity, endpoint, and infrastructure activity even when no shared native field exists. Gurucul delivers true depth for entities, providing context-rich insights rather than just surface-level correlation.
Gurucul’s Chain Analysis automatically stitches related events into contextual chains of evidence.
Instead of chasing individual alerts, analysts see:
This is especially powerful for UEBA, where anomalies gain meaning only when viewed within historical behavior and related activity.
Investigations shift from alert triage to narrative-driven analysis, aligning with the industry’s evolution from event-centric systems to story-based security intelligence.
With activity fully linked and enriched, Gurucul builds high-fidelity behavioral baselines for users and entities.
Gurucul UEBA evaluates:
Anomalies are no longer just “unusual events” — they are contextual deviations tied to intent, risk, and business impact that significantly reduce false positives and surface the real threats earlier.
Once activity is linked and contextualized, security teams can:
UEBA alerts become explainable, defensible, and actionable, increasing SOC confidence and efficiency.
Operationalizing link analysis delivers measurable outcomes:
By linking activity back to real users and entities, security teams move from reactive log review to proactive, intelligence-driven defense.
In a world overflowing with connections, the real challenge isn’t finding links; it’s making sense of them. Traditional link analysis often stops at mapping relationships. Still, the true story lies beneath the surface: the context that shapes those links, the identities that define them, and the correlations that reveal hidden patterns. This isn’t just about drawing lines between nodes; it’s about uncovering narratives that drive decisions, expose risks, and unlock opportunities. As organizations grapple with complexity, operationalizing link analysis with these dimensions isn’t optional—it’s the next frontier in intelligence.
Logs without linkage are just noise. Advanced link analysis transforms fragmented telemetry into a coherent narrative of user and entity behavior — powering UEBA that understands identity, context, and intent. Gurucul’s Next-Gen SIEM doesn’t just correlate events. It connects people, devices, and actions across the enterprise, enabling faster detection, smarter investigations, and better business outcomes.
