A Ponemon Institute study found that 51% of businesses have suffered a data breach caused by an outside party, with 44% suffering a breach within the previous 12 months. Of this 44%, 74% were the result of giving too much-privileged access to third parties. Seeing the large number of cyber-attacks due to third-party companies over the years has created a need to benchmark cyber security models of third-party companies as they serve as vendors to various organizations and risk their data. In this paper, we will discuss why we should use CMMC 1.0 model to benchmark third-party company's cyber security models, and why it would be better to use CMMC 1.0 certification model over CMMC 2.0 model to benchmark third-party company's cyber security models since it offers more benefits even though CMMC 2.0 is latest model and what benefits it offers over CMMC 1.0 certification model with its advantages explained in detail.
