Cybersecurity & IT Services

Grid Square Holdings LLC provides senior‑level cyber and IT expertise that integrates with larger defense and federal programs, complementing prime contractors’ engineering and information management capabilities. With deep experience in RMF, DCO, SOC operations, and vulnerability management, we help programs understand and reduce cyber risk while keeping mission systems ready for operations and inspections. 

We bring seasoned cyber judgment to complex federal IT environments,  reviewing architectures and configurations for security impact and alignment with NIST and DoD guidance. Technical findings are translated into clear risk statements so program and security leaders can make informed decisions. 

Using tools such as ACAS and Nessus, we plan and execute scans, analyze results, and separate high‑impact issues from noise. Outputs include prioritized findings and concise reports that drive remediation with system owners. 

We provide cyber‑focused oversight to system administration activities, reviewing DISA STIG results and advising on remediation plans and  changes. This ensures security improvements strengthen protection without degrading the availability of mission systems.
