Sentinel Blue is a cybersecurity services firm founded in 2019, headquartered in Warrenton, Virginia. The company provides modern cybersecurity solutions specifically tailored to small and medium-sized businesses within the defence industrial base and government contracting community. Its technical domains span cybersecurity, compliance with standards such as CMMC and DFARS, managed security services, Security Operations Centre (SOC) operations, and GovCloud implementations.
The firm offers a suite of fully managed security services including Shield, Overwatch, and Pathfinder, alongside GovCloud implementation services, SOC services, and virtual Chief Information Security Officer (vCISO) offerings. These products address the particular regulatory and operational requirements faced by contractors working with the US Department of Defense and other federal agencies.
Sentinel Blue was among the first companies to achieve CMMC Level 2 Certification under the DoD programme, and it also operates as a CMMC Third Party Assessor Organisation (C3PAO). This dual capability - in both meeting and assessing compliance standards - positions the firm uniquely within its niche. The company was founded by a father-and-son team and remains focused on serving SMBs in the defence and government contracting sectors.
