Why Workspace Security Matters

91% of cyberattacks start with email. A single compromised inbox gives attackers access to Drive, Calendar, Contacts, and every connected third-party app. These guides show you how to break the attack chain at multiple points.

Spoofed email from "your domain"
Employee clicks link
Credentials harvested
Inbox access (no MFA)
Lateral movement to Drive, Calendar, Contacts
