PreVeil Partners

Coalfire Federal

Coalfire Federal is a C3PAO purpose-built to deliver predictable, efficient CMMC Level 2 assessments that Defense Industrial Base contractors can plan their business around year after year. Involved in the CMMC program since its inception and among the first organizations authorized by the Cyber AB, we operate with mature assessment processes that reduce uncertainty, minimize evidence churn, and keep timelines on track. Beyond the initial assessment, we stay with our clients through ongoing validation and reassessments, helping CMMC remain a stable, manageable part of the business and protecting long-term contract continuity.

Guardianshield Cybersecurity

Guardianshield Cybersecurity is a veteran-founded, Authorized CMMC Third-Party Assessment Organization (C3PAO) dedicated to securing the Defense Industrial Base. We help defense contractors move from ‘unsure’ to ‘audit-ready’ by delivering rigorous NIST SP 800-171 Gap Analyses, Remediation Advisory, Mock Assessments, and formal CMMC Level 2 Certification Assessments.

We are purpose-built to support small-to-medium-sized businesses operating with limited time, funding, and in-house cybersecurity expertise. Our assessment methodology is pragmatic and clearly communicated, translating complex DoD requirements into an achievable, cost-effective context rather than expecting you to maintain a massive IT department.
