### [Trustifi Outbound Shield](https://cybersectools.com/tools/trustifi-outbound-shield)

Best for: Companies that must encrypt regulated data

Trustifi is here because it turns a detection into encryption, so sensitive mail still goes out but arrives protected, which suits regulated companies working under HIPAA, GDPR or CCPA. Because it runs on several mail platforms, it also covers mixed setups. Check how people outside your company experience the one-click decrypt and the extra verification step before you roll it out.
