  • Mail Flow The Virtru Hosted Gateway is preconfigured for maximum security and interoperability between systems.

(Example)

  • Mail Encryption Trigger:
    • Outbound 
    • Internal Sending 
  • Mail Flow: Gmail > Gateway > Final Delivery
  • Authorization
    • X-Virtru-Auth: 00000000000000000000 (Virtru provided)
