CyberSheath Services International

CyberSheath is a Registered Practitioner Organization (RPO) specializing in compliance for the U.S. defense industrial base, focused on NIST SP 800-171, DFARS 252.204-7012, and CMMC 2.0. As an RPO rather than a Certified Third-Party Assessment Organization (C3PAO), CyberSheath implements and operationally runs the security controls and managed services needed to meet these requirements, rather than performing the independent certification assessment itself, which CMMC’s rules reserve for a separate C3PAO to preserve audit independence. Its managed services combine 24/7 threat detection, SIEM, and incident response, built on a Microsoft GCC High technology stack, with the evidence collection and documentation defense contractors need to demonstrate compliance.

Founded in 2012 and headquartered in Reston, Virginia, CyberSheath has grown into a specialized compliance and managed-security provider with an estimated 51-200 employees, launching dedicated CMMC managed services in 2020 as the framework began rolling out. The company states it has completed hundreds of NIST 800-171 assessments and implementations for defense contractors, and it operates as a privately held, self-sustaining firm without disclosed venture funding.

CMMC 2.0 is now a binding contractual requirement across the roughly 300,000-company U.S. defense industrial base, giving CyberSheath’s narrow specialization durable, mandate-driven demand. Its RPO status keeps it structurally separated from the assessment and certification role in a way that matches CMMC’s own governance rules, though its specific track record and scale remain company-reported rather than independently audited.
