TL;DR: SIEM migrations often fail because data, query languages, detections, and MSSP-managed baselines are tied to one platform, with detection logic alone consuming 40% to 60% of effort and 70% of modernisation projects underdelivering or failing, according to the source article. The real governance issue is not whether teams can switch, but whether their security architecture is reversible without losing operational continuity.
NHIMG editorial — based on content published by Abstract Security: SIEM 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% to 60% of total project engineering effort.
- Around 70% of SIEM modernization projects underdeliver or fail outright.
- 58% of organizations rate their MSSP as ineffective.
Questions worth separating out
Q: How should security teams reduce SIEM lock-in before a vendor change forces migration?
A: Start by separating what you consume from what you own.
Q: Why does SIEM lock-in create governance risk for identity programmes?
A: Because the organisation loses control over how identity evidence is stored, queried, and operationalised.
Q: What do security teams get wrong about portable detections?
A: They often assume that exporting rule text is enough.
Practitioner guidance
- Inventory portability across the SIEM stack Document whether logs, detections, baselines, and response playbooks can be exported independently of the current platform.
- Store detections as code Move new detection logic into version control using a portable format and keep rule intent, thresholds, and test cases alongside the content.
- Negotiate for content ownership at renewal Require contractual rights to export tuned detections, baseline logic, and relevant telemetry mappings before signing a new SIEM or MSSP term.
What's in the full article
Abstract Security's full article covers the operational detail this post intentionally leaves for the source:
- A practical breakdown of how proprietary query languages shape migration cost and team retraining.
- Specific examples of open data formats and detection-as-code patterns that can reduce platform dependence.
- A staged migration approach for routing data to multiple destinations without a hard cutover.
- The article's discussion of how outsourced SOC tenants create provider lock-in beyond the SIEM platform itself.

Undoable architecture is the right response to SIEM consolidation. The market problem is no longer whether a team can buy a SIEM, but whether it can leave one without losing detection fidelity or operational continuity. That shifts the security conversation from product selection to reversibility, which is a better fit for a market shaped by acquisitions, retirements, and pricing resets. In practice, reversibility is a governance requirement, not a convenience.
A question worth separating out:
Q: Who is accountable when an MSSP-owned SIEM tenant becomes hard to exit?
A: Accountability sits with the organisation that accepted the service model and with the provider that controls the tenant content. Security leaders should define ownership of detections, baselines, and export rights in the contract, because those artefacts determine whether the programme can continue cleanly after a change.
