Video: What You Don’t Know About Microsoft 365 Security

Microsoft 365 emails threats are multiplying in number and complexity. Learn how advanced threat and AI protection can help prevent phishing attacks and account takeovers.

Email is still the easiest way into a Microsoft 365 environment, and attackers know it. Phishing, business email compromise, and account takeovers don’t always look obvious anymore, which is why risky messages can slip into inboxes and sit there until someone clicks. This video explains why that keeps happening and what it means for your Microsoft 365 tenant day to day.

We’ll walk you through the most common ways attackers target Microsoft 365—spear phishing, domain impersonation, and full account takeovers. You’ll also see what stronger protection looks like in practice, using Barracuda Essentials with a focus on Barracuda Sentinel. The key idea is simple: it learns how your team normally communicates, then flags messages that don’t match—like unusual requests, scam-style language, or activity that looks like someone hijacked a real mailbox. It also touches on DMARC-based domain fraud detection, so spoofed emails pretending to be your domain are easier to catch and block.

At CCB Technology, we help teams tighten up Microsoft 365 security without turning it into a giant project. That might mean reviewing what you have in place today, setting up the right email security layers, and making sure alerts are clear and actionable instead of noisy. If your goal is fewer phishing wins and more confidence in what’s happening inside your tenant, this session is a solid place to start.
