Janus is on-site software designed to protect businesses from cyberattacks and data leaks. Unlike traditional methods, this innovation blocks cyber threats using an AI-generated allowlist. Janus learns network behavior patterns, translates complex network logs into concise behavior rules, and dynamically updates the firewall. Its AI automation enables small and medium-sized enterprises to assess security risks without the need for IT specialists. In a hospital, Janus helps detect 360,000 instances of unusual traffic in just four hours, identifying potentially suspicious activities within the communications of IoT-enabled medical equipment.
