Sentinel Blue

Sentinel Blue is a managed security service provider (MSSP) focused on serving government contractors within the defense industrial base and other highly regulated industries. The company develops, implements, and maintains cybersecurity policies and procedures designed to help clients meet regulatory compliance requirements, including CMMC (Cybersecurity Maturity Model Certification). Founded in 2019 by father and son team Don and Andy Sauer, Sentinel Blue is based in Virginia and provides scalable, end-to-end cybersecurity solutions primarily for small and medium-sized businesses, as well as larger enterprise firms operating in government contracting and regulated sectors. The company's services center on compliance-driven managed security, helping organizations navigate CMMC requirements and related federal cybersecurity regulations while also aiming to support long-term operational sustainability. Sentinel Blue publishes research on CMMC assessment readiness, including reports based on input from Certified Third-Party Assessment Organizations (C3PAOs), reflecting its focus on the compliance assessment landscape affecting the defense industrial base. As an MSSP, Sentinel Blue positions itself as a service-based provider rather than a software vendor, working directly with client organizations to implement and manage cybersecurity programs rather than selling standalone security products.
