Defensive Cyberspace Operations (DCO)

Grid Square Holdings LLC provides senior Defensive Cyberspace Operations expertise to help defend federal networks against active and emerging  threats. Support is delivered as part of government and prime‑contractor teams, with priorities aligned with mission systems and authoritative guidance. 

We assist DCO missions by monitoring and analyzing cyber activity, correlating events across multiple sensors, and identifying threats that may evade perimeter defenses. Findings are translated into recommended courses of action and briefings that enable commanders and program leaders to contain, eradicate, and recover from incidents. 

We enhance SOC operations by refining detection logic, reviewing alert quality, and performing in‑depth analysis in tools such as Splunk, McAfee ESM, and ArcSight. The emphasis is on improving signal‑to‑noise ratio, accelerating triage, and providing concise reporting for cyber leadership and stakeholders. 

We conduct detailed analysis of suspected cyber incidents, from initial indicators through scoping, impact assessment, and documentation. Deliverables include written reports and executive summaries that support DoD and federal incident reporting requirements and enable timely, coordinated response.
