TL;DR: Raw logs alone leave SIEM workflows blind to who is acting, what they can access, and whether the resource matters, according to Exaforce. Modern detection needs shared identity, resource, and configuration context, or analysts remain the context engine and AI investigations inherit the same blind spots.
Editorial analysis by NHI Mgmt Group, based on content published by Exaforce: “Why SIEMs Fall Short for Modern Threat Detection”.
Key questions
Q: What breaks when a SIEM relies on raw logs without entity context?
A: The SIEM can still show that events happened, but it cannot reliably tell whether they matter.
Q: Why does missing identity context make alert triage so much harder?
A: Because severity depends on who acted and what they could reach.
Q: How do security teams know if context enrichment is actually working?
A: Look for fewer alerts that require five separate tools to explain, better separation between routine app activity and suspicious user action, and more consistent severity decisions for the same actor across sources.
Practitioner guidance
- Model shared identity resolution Link IdP, SaaS, cloud, and device identifiers so analysts and detections can see one actor across multiple systems and sessions.
- Enrich alerts with resource sensitivity Attach classification, ownership, and access scope to cloud objects, files, and endpoints before routing them for triage.
- Normalize vendor event semantics Map source-specific login, session, and application events into a common model that preserves actor, method, outcome, and target context.
Bottom line: SIEMs that ingest events without shared identity and resource state can record activity but still fail to explain why it matters.

Context blindness is a detection governance failure, not a tuning problem. If the SIEM cannot tell who an event belongs to, what that actor can access, or whether the target matters, the workflow is structurally under-informed. The analyst is forced to compensate with manual lookups, which turns investigation effort into the control plane. The practitioner conclusion is to treat context availability as a core detection requirement, not a nice-to-have enrichment layer.
A question worth separating out:
Q: What should teams do when AI is used for SIEM investigations?
A: Treat AI as a consumer of governed context, not a replacement for it. Give the model access to identity resolution, access posture, and resource sensitivity so its conclusions are grounded in evidence. If it only sees raw logs, it will reproduce the same blind spots that already limit human analysts.
