Cloud Email Security
Dynamic cloud email security that detects and prevents advanced inbound and outbound email threats.

Why Choose KnowBe4 Cloud Email Security?
You need cloud email security products that seamlessly integrate into Microsoft 365 to enhance its native security and detect the inbound and outbound threats that secure email gateways (SEGs) miss.

Protect your organization from the attacks that matter most, including business email compromise, supply chain compromise, and ransomware.

We use contextual machine learning and relationship mapping technologies to understand individual behavior by analyzing who they share data with, and the content they usually share.

Our technology seamlessly integrates with Microsoft 365 to extend their native threat detection across all license tiers, while streamlining management through native controls and zero-friction deployment.
