Working on the perimeter, the Chat Guard acts as an application layer proxy, extracting XML requests and responses and verifying they are acceptable before delivering them.





Attachment stripping –

Body length check –

Dirty word search –

Safe Content

Deep Secure’s unique content transformation technology intercepts chat messages at the perimeter and then re-creates them from scratch, clean and safe on the other side. This destroys the threat. Nothing travels end-to-end but safe content.
