Information Resilience


As today’s increasingly severe times of conflict and recent global events continue to reshape the cyber threat landscape, the need for secure government communication systems to enable the safe passage of information has never been more paramount. Public, private and satellite networks enable commanders to communicate securely at classified and unclassified levels, enhancing strategic and tactical operations in mobile, remote and challenging environments.

Protecting these networks against suspicious or malicious activity that goes beyond the common threats of terrorism and piracy is critical to ensure highly sensitive messages are not intercepted or impeded in the all-important information battle. Through a proven portfolio of world-class, high-grade information resilience solutions, L3Harris enables sensitive, mission-critical data protection both nationally and globally.
