Grid Square Holdings LLC provides senior RMF expertise to help programs navigate authorization and ongoing assessment requirements. Work is performed alongside government and prime‑contractor teams to keep systems aligned with NIST, DoD, and agency guidance.
We support the RMF lifecycle by developing and maintaining security documentation, mapping controls, reviewing evidence, and preparing assessment artifacts in tools such as eMASS. The goal is to give authorizing officials a clear, defensible picture of risk and residual vulnerabilities.
We review existing packages, findings, and configurations to identify gaps before formal inspections or assessments. Results are delivered in focused summaries that prioritize remediation actions and reduce surprises during audits and authorization events.
We help organize and sustain ATO packages by drafting and updating SSPs, POA&Ms, and related artifacts, and by entering and maintaining data in eMASS. This disciplined documentation support lightens the burden on program staff while improving consistency and traceability.
