Organization Seeking Certification (OSC)
An Organization Seeking Certification (OSC) is the formal CMMC term for a company that is going through the CMMC assessment process. If you're a defense contractor preparing for or undergoing a CMMC assessment, you are the OSC.
The term is used in official CMMC documentation and assessment guides to distinguish between the company being assessed and the organizations performing or overseeing the assessment (C3PAOs, CyberAB, DIBCAC).
Why It Matters
Knowing this terminology helps you navigate CMMC documentation and assessment procedures. When guides and policies reference the 'OSC,' they're talking about your company and your responsibilities in the certification process.
