Hunt Threats Before They Hit: Managed ITDR for Microsoft 365

Introduction 

For many UK businesses, recent headlines have triggered a serious rethink of their security posture.

As household names scramble to contain breaches and restore customer trust, small and mid-sized businesses are asking a vital question: how can we detect attackers before damage is done?

That’s where Huntress Managed ITDR comes in. Built specifically for Microsoft 365, it watches for signs that attackers have gained access and stops them before they dig in.

Why the phishing threat is only getting worse

Did you know that, according to the ICO, almost half of UK businesses saw a cyber breach in the last 12 months? And of those, a whopping 19% were down to phishing?

Whether it’s an iffy-looking link or a convincing voice‑cloned call, hackers are always hunting for the human weak spot. Take Marks & Spencer’s April attack: hackers slipped in via a third‑party system, paused online orders for weeks, and made off with sensitive customer data.

If a retail giant can fall victim, what hope do smaller businesses have without a serious cloud identity defence?

That’s where solutions like Huntress come in. Their platform goes beyond simple login monitoring, it actively watches for tactics like:

• MFA bypass attempts (including fatigue attacks)
• Suspicious changes to forwarding rules or app installation
• Token misuse, where attackers hijack valid session tokens to gain access even after MFA
• Unusual country location access

This level of scrutiny is essential in today’s phishing landscape because even the most careful users can be tricked. 

What Is Identity Threat Detection & Response (ITDR)?

Think of it as breach detection for your Microsoft 365 accounts. 
 
You wouldn’t run laptops without antivirus, so why leave user identities unmonitored in the cloud? 
 
Huntress Managed ITDR continually watches your Microsoft 365 environment for suspicious activity. From suspicious logins and MFA bypasses to Shadow Workflows, Huntress shines a light on the tactics attackers use once they’re inside. 

How Microsoft 365 Breach Detection Works with Huntress

Huntress brings human-powered threat detection to Microsoft 365, watching every sign-in, permission change, and unusual action in your tenant.
Here’s what sets it apart:

• Real-Time Threat Detection: Huntress continuously monitors your Microsoft 365 environment to detect suspicious sign-ins, credential misuse, and post-compromise activity. It looks beyond basic anomaly detection to identify tactics used by real attackers, like MFA fatigue or malicious OAuth apps.
• Expert Human Threat Hunters: Not just machines. When Huntress flags a potential threat, their 24/7 human security team investigates and confirms malicious activity. You don’t get flooded with alerts, you get verified threats and a clear action plan.
• Rapid Response, with Zero Guesswork: If something’s wrong, you’ll know fast. Huntress delivers clear, actionable incident reports and can work with your team, or ours, to contain the threat quickly and decisively. No jargon. Just the facts.
• Threat Actor Tradecraft, Uncovered: Huntress watches for known attacker tactics in Microsoft 365, including:
  • Session Token Theft Detection
  • Credential Theft Detection
  • Unwanted Access Rules
  • Unexpected Country / VPN Escalations
  • Mailbox rules
  • Rouge Applications

Why Managed ITDR Is Now Essential 

For years, SMEs thought breach detection tools were out of reach, reserved for big-budget enterprises. But as cyber threats target smaller businesses more frequently, having visibility into Microsoft 365 is no longer optional.

And unlike traditional monitoring tools, Huntress ITDR gives you access to a real team of threat hunters, making enterprise-grade defence accessible to every business.
