Sophos MDR (Managed Detection and Response) is a fully managed, 24/7 cybersecurity service where Sophos security experts continuously monitor an organisation's environment, hunt for threats, investigate suspicious activity, and take action to contain and eliminate attacks.

What Sophos MDR does:

• 24/7 monitoring: Continuously watches endpoints, servers, networks, cloud workloads, email and other security signals.

• Threat detection: Uses AI/automation, machine learning, behavioural analytics and threat intelligence to identify malicious activity.

• Threat hunting: Proactively searches for attackers that may have bypassed traditional security controls.

• Investigation: Sophos analysts investigate alerts to determine whether they represent genuine attacks rather than simply passing alerts to your IT team.

• Response: Depending on the service configuration, Sophos can contain and neutralise threats on your behalf, rather than merely notifying you.

  Third-party integration: Sophos MDR can work with existing security technologies, with Sophos currently advertising 500+ integrations.

  Human + AI: Sophos combines automated/AI-driven analysis with human security analysts who oversee decisions and handle cases requiring human judgement.

Why organisations use it:

It is particularly useful for organisations that:

• Don't have enough security staff to provide 24/7 coverage.

• Want specialist threat-hunting expertise.

• Need faster incident detection and response.

• Have security tools but lack the resources to operate them effectively.

• Want to retain existing security investments rather than replace everything.
