The document discusses Sophos' Security Heartbeat technology, which allows various Sophos security components like firewalls, endpoints, servers, and mobile devices to share security information in real-time. This enables automatic containment of threats by isolating infected devices, protection of critical data by removing encryption keys from infected machines, and full visibility of application traffic across the networked environment. The Security Heartbeat works across various currently supported operating systems and Sophos products and provides synchronized security by analyzing data and responding automatically to incidents and unknown threats.
