Identity Observability Using SIEM Data:
From Alerts to Evidence-Based Governance

Security Information and Event Management (SIEM) platforms generate enormous volumes of data every day—logs, alerts, behavioral anomalies, threat indicators. Yet most identity governance programs never fully leverage this data. Access decisions are made based on static roles and periodic reviews, not on what is actually happening in the environment right now.

Detekti changes this. By integrating natively with leading SIEM platforms—Splunk, QRadar, Elastic Security, and others—Detekti transforms raw security event data into meaningful identity context, enabling a new category of governance we call Evidence-Based Identity Governance.

The Gap Between SIEM and Identity Governance

Traditional SIEM platforms excel at detecting threats: anomalous login patterns, lateral movement, privilege abuse, data exfiltration. But they typically operate in isolation from the identity governance layer. A SIEM alert might flag that a user accessed a sensitive resource at 2am from an unusual location—but the identity governance system has no awareness of this event. The next access certification cycle will proceed as if nothing happened.

This disconnect creates a dangerous blind spot. Organizations can be compliant on paper—roles certified, SoD conflicts resolved, access reviews completed—while remaining exposed to real, active threats that the SIEM has already detected but that governance processes have not acted upon.

How Detekti Integrates SIEM Data into Identity Governance

Detekti's integration engine connects directly to SIEM data sources, ingesting security events and correlating them with identity records. This correlation works across four dimensions:

1. Behavioral Enrichment

Every identity in Detekti can be enriched with behavioral signals from the SIEM: failed authentication attempts, unusual access hours, access from new geographies, privilege escalation events, and more. This data is not just stored—it is surfaced within the identity profile, making it visible to reviewers during certification campaigns and access decisions.

2. Risk Scoring Informed by Security Events

SIEM alerts directly influence the risk scores assigned to identities in Detekti. A user with multiple high-severity SIEM alerts in the past 30 days will have an elevated risk score, triggering more frequent review cycles or requiring additional justification for access renewals. Risk scoring is dynamic, not static.

3. Contextual Evidence Attachment

When a SIEM event is correlated with an identity, Detekti automatically creates an evidence record. Governance operators and security analysts can annotate this record with investigation notes, remediation actions, and supporting documents. This creates a complete, context-rich audit trail that goes far beyond standard access logs.

4. Audit-Ready Evidence Reports

Detekti can generate PDF reports that combine identity governance data (certifications, SoD analysis, access history) with SIEM-derived behavioral evidence (anomaly alerts, threat indicators, investigation notes). These reports are designed to be submitted directly to auditors and regulators, eliminating the manual effort of correlating data from multiple systems.

Evidence-Based Identity Governance: A New Standard

The concept of Evidence-Based Identity Governance goes beyond traditional compliance. Instead of asking "does this user have the right access according to our policies?", it asks: "Can we demonstrate, with documented evidence, that this user's access is appropriate given their actual behavior and the current threat landscape?"

This distinction matters enormously in regulated industries. Financial services regulators, healthcare compliance bodies, and data protection authorities increasingly expect organizations to demonstrate not just that controls exist, but that those controls are operating effectively in practice. Evidence-based governance provides exactly this.

Detekti enables this through three specific capabilities:

• Identity Timelines: Visual, chronological records of every access state, role assignment, and governance action for each identity. Reviewers can see at a glance how long a user has held a given permission, when it was last certified, and what behavioral signals have been recorded during that period.
• Contextual Annotations: At every governance touchpoint—access requests, approvals, certifications, risk reviews—stakeholders can attach notes, documents, and justifications. These annotations become part of the permanent audit record.
• PDF Evidence Reports: On-demand generation of comprehensive reports that include all attached evidence, SIEM-derived context, certification decisions, and reviewer comments. Ready for auditors on day one.

Practical Implementation: SIEM + Detekti

Integrating a SIEM with Detekti is straightforward through the native connector library. The integration follows a four-step flow:

1. Connect the SIEM to Detekti using the native connector (Splunk, QRadar, Elastic Security, or custom via the Pentaho-based integration engine).
2. Map SIEM event types to identity risk indicators within Detekti's configuration interface.
3. Define thresholds and escalation rules: which events trigger risk score increases, which require immediate review, and which are recorded as evidence without immediate action.
4. Review the enriched identity profiles during certification campaigns, with full behavioral context visible alongside traditional governance data.

Conclusion

SIEM data represents an underutilized asset for identity governance teams. When properly integrated, it transforms periodic, policy-based reviews into continuous, evidence-driven governance—where every access decision is informed by real behavioral data, and every audit finding can be answered with documented evidence.

Detekti is the platform that makes this possible. By combining IAM, IGA, and Identity Observability in a single solution—enriched with SIEM data and built around the principles of Evidence-Based Identity Governance—Detekti gives organizations the visibility and documentation they need to govern identities with confidence.
