Sophos MDR and Microsoft: Beyond "Better Together"

Better Together Means Better Protected

Events are analyzed, correlated, and prioritized, enabling analysts to quickly investigate and respond to threats.

Alert fatigue is a business problem, not just a security one

Every unreviewed Microsoft alert is unpriced risk sitting on your balance sheet, and the expertise needed to triage it is the hardest thing in security to hire. Sophos MDR absorbs that work so your internal teams stop firefighting and get back to initiatives that grow the business.

Unlock more protection from the Microsoft technologies you already trust

With turnkey Microsoft 365 and Microsoft Graph Security integrations built in, Sophos MDR is ready to defend your environment from day one — no lengthy setup or additional licensing required.

Built-in response actions for fast containment

Sophos MDR can execute response actions directly within your Microsoft environment through deep, two-way integrations. Our analysts act on your behalf to revoke Microsoft 365 sessions, disable user signins, suspend malicious inbox rules, and more — stopping threats before they spread and reducing pressure on your internal team.

No forced migration, no wasted licences

Adopting MDR does not mean tearing out what you already bought. Keep Microsoft Defender for Endpoint, take Sophos Endpoint at no extra cost, or stay on a third-party tool — the service adapts to your stack rather than the reverse.
