Webhook Security: Discovery, Validation, Monitoring

Webhooks quietly move sensitive data between systems — often with no visibility, no ownership, and no monitoring. They power automation, SaaS integrations, and modern workflows, but they also create a blind spot inside Microsoft 365, Azure, and third-party platforms. This guide explains how webhooks work, why they’re risky, and how to govern them  using a practical framework built on discovery, validation, and continuous monitoring .

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 Microsoft 365...

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  by persuading a...
