Strengthen your Microsoft Defender strategy with Sophos MDR

The reality: attackers don’t break in - they log in 

Modern adversaries behave like legitimate users, exploiting weak points such as unpatched vulnerabilities, compromised credentials, and abused admin tools. They adapt in real time, pivoting until something works. Many organisations struggle to keep pace - in fact, the Cyber Security Breaches Survey 2025 found that 43% of businesses reported a cyber security breach or attack in the last 12 months. Businesses also reported a significant increase in temporary loss of access to their files or networks (7% - up from 4% in 2024). 

This isn’t a tooling problem. It’s a visibility, expertise and capacity problem.  

That’s where Sophos MDR for Microsoft Defender changes the game. 

Why Sophos MDR for Microsoft Defender stands out 

Sophos MDR combines Defender telemetry with human expertise, advanced AI, and threat‑hunting intelligence to stop threats before attackers can cause real damage. At the heart of the service is a global team of over 500 specialists working across seven security operations centres, delivering world‑leading detection and response times - including a mean time to detect of one minute.  

With Sophos MDR for Microsoft Defender, you get: 

24/7 monitoring and response 

Sophos analysts watch over your Microsoft Defender alerts around the clock, stepping in the moment something looks suspicious - even isolating your devices and neutralising attacks on your behalf.  

Threat protection beyond Microsoft Defender 

Using Sophos threat intelligence, human-led hunting, and telemetry from your wider environment - firewall, cloud, identity, email, network - the service identifies threats that evade standard detection. 

A smarter way to maximise your existing investment 

Sophos MDR doesn’t replace Microsoft Defender - it elevates it. The service integrates seamlessly with Defender for Endpoint, Defender for Identity, Defender for Cloud, Azure AD Identity Protection, and more. 

You get more value from the licences you already pay for, while freeing your teams from alert noise and time‑consuming investigations. 

What this means for your organisation

1. Reduced cyber risk

Threats are identified and contained fast. Sophos’ “community immunity” approach means intelligence from one customer helps protect others instantly. That’s how thousands of businesses worldwide stay ahead of emerging attack techniques.  

2. Increased efficiency

On average, organisations spend nine to 15 hours investigating and responding to a single alert. Sophos MDR shortens that dramatically, giving your IT teams time back to focus on strategic initiatives - not firefighting.

3. Improved insurability

Insurers increasingly require 24/7 detection and response. Sophos MDR helps organisations meet these requirements and, in many cases, secure more favourable premiums.
