What is the role of the Sophos Security Heartbeat?

The role of the Sophos Security Heartbeat is focused on enabling communication between Sophos endpoints and the firewall, creating a cohesive security environment that works in real time to protect against threats. This feature allows endpoints protected by Sophos to share their security information with one another and with the Sophos firewall. When a threat is detected or an endpoint's health is compromised, the information is communicated promptly, allowing the firewall to take necessary actions, such as blocking network traffic from infected devices or quarantining them to prevent the spread of malware.

The other options do not align with the primary function of the Security Heartbeat. While enhancing network speed, managing user access, and encrypting sensitive data are important aspects of a comprehensive security strategy, they are not the specific purposes served by the Security Heartbeat. Its main utility lies in the real-time communication and threat response capabilities it provides within the Sophos ecosystem. This helps organizations respond more effectively and maintain a higher standard of security across their network.
