Detect and Control Third-Party Document Security Risks

Threat Radar and Terminator in One Package?

We all rely on third-party systems, such as cloud drives, partner portals, vendor mailboxes, and more. But here’s the problem with traditional defenses. They can only guard what’s inside your walls.

Once your sensitive documents land in a partner’s mailbox or a third-party system, you don’t have any control, and are often blind to what happens next.

The reality is:

  1. Traditional perimeter security stops at your firewall
  2. Once data lands in someone else’s inbox or file system, it’s often unprotected
  3. Plus, if that third-party system is compromised, your sensitive documents can be exposed

A smarter approach is having the right tools like RPost’s RAPTOR™ AI that can: 

  • See who is accessing your sensitive files, even in third-party systems.
  • Analyze real-time forensic transport protocol data (plus external intel, dark web chatter, and LLM insights) to spot when unauthorized parties are accessing your documents.
  • Even attribute the threat activity to specific cybercriminal groups, so you know exactly who’s behind the attack.

Now, you might think that having warnings is good, but what you really want is action. That’s where RDocs™ steps in by: 

  • Double-Lock™  (ing) your sensitive pages in a document for controlled access to a select group of people, while keeping the rest of the pages visible to the wider audience.
  • Auto-killing the document remotely, agentically if it has outlived its utility.
  • Disabling the access remotely if your document is being accessed by threat actors.

And what happens if you have a combo of RAPTOR and RDocs? You get Threat Radar and Terminator rolled into one neat package.

You’re not just watching your perimeter. You’ve got a live radar of risks outside your network and the ability to terminate them before they cause harm.
