Data Leak Prevention in ClrStream

Data leak prevention for the Inbound mail flow

In addition to the mail policies which can control inbound, internal and outbound mail flow, you can configure some additional data leak prevention rules for the Inbound mail flow.

Your domain can be configured to Intercept, Modify or Monitor the incoming mail flow.

The Intercept actions possible are: 

  • Deliver now

  • Delete message

  • Quarantine 

  • Change recipient

The Modify actions possible are:

  • Clean cleanable malware, delete those that cannot be cleaned
  • Stamp the body with a cautionary message.
  • Tag the subject with keywords which alert the recipient that the mail is from an external sender
  • Delete matching attachments

The way to Monitor such Inbound mail would be to:

  • Send an email notification to a predefined email id
  • Send a bcc of the inbound mail to a predefined email id.

These actions can be taken for mails which match one or more of these conditions

  • all inbound mail 
  • all inbound mail for a selected set of users on your domain
  • mail from a selected set of senders to any user on your domain
  • mail from a selected set of senders to a select set of recipients on your domain
