Leidos Cybersecurity Solutions

Leidos builds cybersecurity into mission architecture from the start rather than bolting it on after the fact, which is exactly the approach you want from the company protecting defense, intelligence, and critical infrastructure systems where downtime isn't measured in lost revenue but in compromised national security. As a systems integrator, Leidos brings cyber operations, AI, data engineering, and security together into unified solutions that operate securely under pressure and adapt as threats evolve. Their predictive, intelligence-led cybersecurity combines Cyber AI with deep mission expertise to help organizations stay ahead of threats rather than chasing them.

Recent work tells the story better than any capability deck. Under a $142 million DISA award, Leidos is modernizing IT operations for the Compartmented Enterprise Services Office with scalable, AI-driven capabilities designed to streamline operations, improve secure information access, and advance Zero Trust compliance. Their GSM-O II team piloted Endguard, a comprehensive endpoint detection and response solution leveraging Microsoft Defender for Endpoint and Microsoft Defender for Servers, demonstrating the kind of vendor-agnostic integration that defense environments demand. Cyber defense spans from internet perimeter to endpoint, with visibility across the entire attack surface.

For defense agencies and intelligence organizations that need cybersecurity woven into complex mission systems rather than layered on top of them, Leidos delivers the integration depth that comes from decades of building and operating the systems they protect. When your security provider understands the mission as deeply as the threat landscape, the result is resilience that's architectural rather than aspirational.
