What Happens If Someone Gets Past Your Microsoft 365 Login?

Most companies believe their email is safe. MFA is on, a spam filter is running, and they assume that combination covers them. It doesn’t.

Both only guard the entrance. A spam filter stops bad messages. MFA mostly stops the wrong person from signing in – but it is easily defeated. And, neither watches what happens after someone gets in — and hackers do get in. A stolen password, a tricked employee, a compromised device. It happens.

Once an attacker is inside a real account, your spam filter sees nothing wrong. The mail is coming from a trusted user. That’s the gap we close. Sentinel for M365/Google Workspace is our 24x7x365 active security for your Microsoft and Google environments. Instead of just guarding the front door, it watches what happens after someone signs in: the account, the mailbox, OneDrive, SharePoint, Teams, and Drive. It looks for suspicious sign-in activity, mailbox behavior that isn’t normal, hidden forwarding rules, and changes that don’t match how that employee usually works. MFA and a spam filter protect the front door. Sentinel is what notices when someone gets through it anyway. Visit www.computer-service.com/M365 for a quote.
