Category Pressure

CISA awarded Elastic a $26M base-year contract to build a unified SIEMaaS platform for federal civilian agencies, with options to $130M over five years. The first tenant is already deploying. This is not a product win. It is infrastructure positioning.

What Changed

Federal SIEM has operated as agency-owned, agency-operated infrastructure since the category existed. EO 14028 and M-21-31 mandated logging improvements but left telemetry fragmented across independent deployments. CISA is now building a parallel structure: a shared, cloud-hosted analytics layer that agencies can adopt without procurement cycles or rip-and-replace decisions.

The shift is from tool selection to dependency formation.

Why This Matters Structurally

Federal security vendor go-to-market models are built on agency-by-agency displacement. That model survives only if agencies retain operational ownership of their detection infrastructure. Once telemetry flows into a shared platform operated by CISA, the procurement surface collapses upstream. Vendors compete to feed the platform, not replace it.

Once dependency formation begins, vendor choice becomes a secondary concern.
