Cybersecurity
Offensive, defensive, and cyber resilience across every mission
Cyber authority meets unmatched agility
Adversaries seek undetected access to your systems and data, constantly looking for vulnerabilities that give them a way in. Staying ahead means closing those gaps before they can be exploited.
Leidos combines threat insight, applied AI, and real-world operator experience to anticipate and disrupt adversarial activity. We deliver integrated offensive, defensive, and resilience capabilities — supported by research and workforce development — to help agencies stay secure and mission-ready.
Trusted cyber. Real mission impact.
Built for the Mission
We protect defense, intelligence, and critical infrastructure systems where failure is not an option. From architecture to operations, we design for resilience–measured by uptime, mission continuity, and confidence at every level of command.
Security by Design
As a systems integrator, we bring cyber operations, AI, data, and engineering together from the start. Protection is built into mission architecture–not added later–so systems operate securely under pressure and adapt as threats evolve.
Intelligence Applied
Our analysts and operators work side by side with mission teams, translating real-world threat intelligence into decisive action. By detecting and containing risks early, we help agencies stay ahead of disruption and focused on what matters most.
Offensive Cyber for Modern Conflict
Leidos delivers AI-enabled offensive cyber that uncovers weaknesses, accelerates exploit development, and generates non-kinetic effects across cyber, electronic warfare, and electromagnetic spectrum operations.
Defensive Cyber for Mission Assurance
Leidos safeguards the world’s most critical networks, securing millions of connections across enterprise, cloud, military, and critical infrastructure with verified cyber readiness and trusted security certifications.
Cyber Resilience for Critical Systems
Leidos secures mission-critical systems across land, sea, air, space, and infrastructure–engineering trusted hardware, testing defenses with elite red teams, and responding with coordinated precision.
