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.
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.
