If you’re a business leader or IT decision-maker relying on Microsoft 365, the reality in 2026 is uncomfortable.

Attackers no longer need to “break in.”  They simply log in using stolen credentials, MFA fatigue, token abuse or legacy protocol exploits.

Recent examples make this painfully real:

• In March 2026, an Iran-linked threat actor conducted a widespread password-spraying campaign against Microsoft 365 environments, targeting over 300 organisations in Israel and more than 25 in the UAE.
• In September 2025, Microsoft issued an emergency patch for CVE-2025-55241 – a critical Entra ID vulnerability that could have enabled attackers to impersonate Global Administrators across tenants.
• Microsoft reported that over 97% of identity attacks continue to be password spray or brute-force attempts.

Traditional security tools are largely reactive. By the time your team investigates the alerts, the attacker has often already moved laterally or exfiltrated data.

That’s exactly why Adlumin Identity Threat Detection and Response (powered by N-Able and delivered by IP Dimension) exists.

Adlumin doesn’t just detect threats, it automatically stops them before they spread.

It monitors real-time telemetry from Entra ID, Exchange and Microsoft Graph, builds behavioural baselines with machine learning and instantly triggers automated responses (such as forcing password resets or disabling suspicious accounts) when anomalies are detected.

The result is real breach prevention – not just more alerts.

No agents. No added complexity. Just intelligent protection that works with the Microsoft 365 environment you already have.

If you’re tired of reacting and ready to start preventing identity threats automatically, now is the time.

Take the next step today: 

Visit https://ipdimension.co.za/n-able-m365-breach-prevention/ to download the Adlumin datasheet or request a meeting/demo with IP Dimension.

The next attack isn’t a question of “if”, it’s a question of “when.”  Make sure your defences are ready.
