Independent Validation. Risk-Based Insight. Mission-Ready Security.
Federal agencies and critical infrastructure organizations are under constant pressure to demonstrate that their security controls are not just documented — but implemented, operating effectively, and resilient against real-world threats.
MSM-NET, INC. dba MSMNET Security delivers independent Security Control Assessment (SCA) services aligned to NIST Risk Management Framework (RMF) and NIST SP 800-53, helping organizations validate security posture, support Authorization to Operate (ATO), and strengthen continuous monitoring programs.
