The Hidden Danger of “Connected Apps” in Microsoft 365—and How to Fix It
Microsoft 365 / Entra ID connected apps (OAuth) power everything from e-signatures and CRM sync to ticketing and file automation. The danger is that “helpful” integrations can quietly accumulate broad access—mail, files, directory data—without ongoing oversight. When something goes wrong, the cost shows up fast. That’s why the ROI of Microsoft 365 app governance is now one of the simplest, most defensible security investments you can make. ROI of Microsoft 365 App Governance

Microsoft 365 Connected Apps Risk Assessment & Governance
Identify risky Microsoft 365 / Entra ID connected apps (OAuth), understand their permissions, and enforce ongoing governance — without spreadsheets or guesswork. Microsoft 365 connected apps governance is the process of maintaining visibility and control over third-party and internal applications that access Microsoft 365 through OAuth. These connected apps often operate with delegated or application-level permissions and do not rely on an interactive user session. Modern Mi

Consent Phishing in Microsoft 365: How It Works & How to Prevent It
Consent phishing in Microsoft 365 is when an attacker tricks a user into granting a malicious application access via OAuth (Open Authorization) instead of stealing a password. The fake app presents a consent screen requesting risky scopes. Once approved, the attacker gets long-lived token access through a service principal—often bypassing MFA. Quick definition Consent phishing—also called an illicit consent grant —is when an attacker gains access without stealing a password
