Over the weekend, some organizations using Microsoft Entra ID experienced unexpected user lockouts tied to a new security feature rollout specifically, the MACE Credential Leak Detection app, designed to proactively disable potentially compromised accounts.

While this tool adds an important layer of security, it also caught many IT teams off guard, especially those without dedicated support or visibility into conditional access changes.

At Red Level, we see this as a reminder of just how critical it is to have an experienced Managed Services Partner (MSP) in your corner, someone who can help you adapt quickly, respond efficiently, and keep your business running smoothly.

What Happened

In certain environments where Phase 2 security baselines were active, Microsoft’s rollout of the MACE app triggered widespread account lockouts. Even accounts with strong passwords and Multi-Factor Authentication were affected.

This wasn’t a breach or a bug, it was a well-intentioned rollout of a new feature that behaved a little more aggressively than expected.

Red Level clients didn’t have to scramble. Our team had already identified the root cause and began working through any affected environments. Our managed clients experienced little to no disruption, and any necessary follow-ups were quickly addressed by our team.

Why This Matters to Your Business

New security features like this are a great reminder: tools and technology alone aren’t enough. You need context. You need support. And you need a partner who’s paying attention, especially when things change fast.

Here’s how a Managed Service Provider like Red Level helps:

• Proactive Monitoring: We stay on top of security updates, feature rollouts, and policy changes.
