TL;DR: SIEM lock-in now spans data formats, query languages, detection content, and MSSP tenants, not just log export, according to Abstract Security, with migration effort often dominated by rewritten detections and platform-specific skills. Reversible architecture, not replacement urgency, is the real control variable when vendor change becomes unavoidable.
Editorial analysis by NHI Mgmt Group, based on content published by Abstract Security: “Escaping Lock In Hell - How to Not Care If Your SIEM Vendor Doesn't Exist Next Year”.
By the numbers:
- Detection logic migration consumes 40-60% of total project engineering effort.
- Around 70% of SIEM modernization projects underdeliver or fail outright.
- Outsourced SOCs cost $4.44M per year versus $2.86M in-house, a 55% premium.
Key questions
Q: What breaks when SIEM detections are trapped in one vendor format?
A: Migration usually breaks at the detection layer, not the log layer.
Q: Why do SIEM migrations create security risk even when the new platform is working?
A: Because the risk is usually in the surrounding data pipeline, not the platform itself.
Q: How do security teams know if their SIEM architecture is reversible?
A: A reversible SIEM architecture lets you export usable data, port or rebuild detections, and remain operational during a staged cutover.
Practitioner guidance
- Audit reversibility across the security stack Test every major tool for open data export, portable detection export, and realistic time-to-recovery if the vendor disappeared tomorrow.
- Store new detections as code Write fresh detection content in a version-controlled format such as Sigma so rules can be reviewed, tested, and translated outside one vendor tenant.
- Separate data transport from detection dependency Evaluate whether an abstraction layer can keep sources, normalization, and detections decoupled enough to support a phased migration.
Bottom line: SIEM lock-in now spans data, detections, skills, and provider tenancy, so exit readiness is an architecture issue rather than a platform preference.

Undoable architecture is now the more useful security principle than SIEM loyalty. The article shows that modern SIEM dependence is spread across data, detection content, skills, and provider tenancy, which means the real control question is whether the stack can be reversed without operational collapse. For practitioners, this reframes procurement from feature selection to exit resilience.
A question worth separating out:
Q: How should organisations govern SIEM and MSSP ownership to avoid lock-in?
A: They should treat telemetry, detections, and baselines as organisation-owned assets even when a provider operates them. That means defining export rights, validating rule portability, and checking that provider change does not require rebuilding the entire monitoring model from zero.
