Is someone reading your email right now?
Hidden forwarding rules. Unauthorized access. Compromised credentials. Find out in 60 seconds. Free.
Metadata only. We never read your email content.
What We Check
Three threat categories that antivirus and spam filters cannot see.
Hidden Forwarding
Rules silently copying your email to an attacker's inbox. No malware, no phishing link -- just a settings change nobody saw.
Unauthorized Access
Delegates, OAuth apps, and sessions you didn't authorize. Third-party apps with full mailbox access you never approved.
Sign-in Activity
Suspicious logins, failed attempts, impossible travel. Someone logging in from a country you've never visited.

This Is What We Find
Real examples of threats detected by InboxWatch that went unnoticed by traditional security tools.
A law firm had all incoming email forwarded to an external address for 4 months before anyone noticed.
A single mail rule -- invisible in the inbox -- was exfiltrating every client communication.
An employee's OAuth app had full mailbox read access without their knowledge.
A forgotten app authorization from years ago still had complete access to every email and attachment.
A CEO's account showed successful logins from two countries 3 hours apart.
Impossible travel detection flagged credential compromise before any data was exfiltrated.
