Understand the Content Before It Leaves

An incorrectly addressed email or an unauthorized file transfer can create a data exposure incident without any malicious intent.

Content-aware policies evaluate message bodies, attachments, and recipient domains in real time—allowing legitimate external collaboration while stopping misdirected or unauthorized transfers.

How does it work?

  1. Inspect outbound traffic

    Outbound mail and web uploads are checked before they leave.

  2. Read the content

    Body, attachments and uploads are checked, not just the destination.

  3. Decide per recipient

    The same file can go to a customer and not to a personal inbox.

  4. Act

    Block, warn, ask for a reason, or record.

What does it cover?

  • Outbound email

    Block, warn, ask for a reason or record, in Outlook and over SMTP.

  • Web uploads

    Webmail, cloud storage, social media and messaging web clients.

  • File transfer

    FTP and SFTP are blocked at the network level, not read.

  • Mail platforms

    Microsoft 365, Google Workspace and Exchange.

  • Misdirected recipients

    A warning when internal data is about to reach an outside address.

Questions about Network & Email DLP

What about laptops away from the office?

The same agent covers them. Mail sent from a desktop client and uploads from a laptop at home follow the same policy as in the office, and the evidence reaches the policy server when the laptop reconnects.

Does email follow the same rules as everything else?

Yes. The Outlook add-in and SMTP use the same ordered rule table as USB, web and cloud, so a file keeps its policy across every channel. The evidence lands in one place, whichever way the file tried to leave.
