Create Virtru Encryption Rule 

Once the message is routed to the Virtru Hosted Gateway, a Virtru DLP Rule must be created and enabled to evaluate the message and encrypt.  Each Virtru DLP Rule is evaluated against each message sent to the Virtru Hosted Gateway.  The Virtru DLP Rules are shared between the Virtru Hosted Gateway and the Virtru Clients.
