Rimstorm, founded in 2012 and based in London, is a managed security service provider whose GovCon Enclave product helps small and mid-sized US defense-industrial-base contractors achieve CMMC Level 2 certification, packaging a managed enclave engineered around CMMC Level 2 control requirements to reduce the integration burden for contractors without in-house compliance engineering.
Government-contractor back-office firm BOOST LLC, backed by The Brydon Group, acquired it in March 2026, a logical channel fit that folds Rimstorm into a much larger non-security parent.
Innovation Matrix Assessment
Applies established managed-enclave architecture to CMMC compliance rather than introducing novel security technology.
Addresses a concrete, mandatory compliance gate (CMMC Level 2) that directly threatens contract eligibility for its target customers.
March 2026 acquisition by BOOST LLC, a 800-contractor-strong back-office services firm, gives Rimstorm a built-in distribution channel.
Operates within an established MSSP/compliance-services model rather than creating a new category.
No independent, third-party data on certification pass rates or enclave security posture is publicly available.
CMMC 2.0 enforcement is actively ramping across the defense industrial base, sustaining demand for this category for years.
Why CISOs Should Care
Rimstorm is a managed security service provider whose flagship GovCon Enclave product helps small and mid-sized U.S. defense industrial base contractors achieve CMMC Level 2 certification, an increasingly mandatory gate for Department of War contract eligibility.
What Makes It Different
Rather than general MSSP services, Rimstorm packages a purpose-built managed enclave specifically engineered around CMMC Level 2 control requirements, reducing the integration burden for contractors who lack in-house compliance engineering.
The Matrix Verdict
42/100 — EMERGING / UNRANKED
A focused compliance-infrastructure play riding active CMMC 2.0 enforcement; the March 2026 acquisition by government-contractor back-office firm BOOST LLC (backed by The Brydon Group) is a logical channel fit but folds Rimstorm into a much larger non-security parent.
