S-RM Polus MDR if

  • You want external exposure monitoring alongside managed endpoint response.

Sophos MDR if

  • You want to compare Sophos agents, sensors and supported agentless endpoint integrations.

Consider neither if

  • You need a provider to run your wider SOC or own system restoration.

Questions to ask both

  1. Show us the supported actions on our actual endpoints, including approval and unreachable-contact rules.
  2. Which assets receive hands-on incident response, and who owns vulnerability fixes and recovery?
  3. Itemize endpoint licensing, integration fees, external exposure monitoring and incident-response entitlements.
