Shadow AI DLP

Let employees use AI. Keep sensitive data out of the prompt.
Sentra shows every AI app your people use, from ChatGPT and Claude to Gemini and Copilot, and stops regulated or proprietary data before it leaves the browser. Classification runs locally. Nothing is proxied.

AI DLP Application Policies

Your data is already in AI prompts. Legacy DLP can’t see it.

Work finds a way

Employees paste records, contracts and code into AI tools, often from personal accounts.

Built for files, not prompts

Web gateways and CASBs watch transfers and known SaaS, not text typed into a chat box.

No recall button

Once data reaches a third-party model, it can't be pulled back. Prevention is the control.

Blocking backfires

Blanket bans push AI use to unmanaged devices and cost the productivity you wanted.

Sentra stops sensitive databefore it is pasted into AI apps

  • Shadow AI Discovery
    Sanctioned and unsanctioned AI app usage, with the risk of each.
  • Classification in the browser
    Same Sentra data classes, on the device. No proxy, no content sent out.
  • Policy by app and data class
    Block, allow, log, require justification or prompt to verify.

Visibility and prevention in one control

Shadow AI discovery

See which AI apps are in use, by whom, through corporate or personal accounts, and how often. Build your sanctioned list from real usage, not assumptions.

Prompt-level protection in the browser

Content is classified on the device as users type, paste or upload, using the same classifiers that power the rest of Sentra.

Policies by app and data class

Allow an approved assistant for everyday work while blocking PHI, source code or customer data. Treat unsanctioned tools differently.

A complete audit trail

Every event records the user, the AI app, the data class and the action taken, ready for investigations and audits.

More than block or allow

Block

Stop the submission and tell the user why.

Allow

Let low-risk use flow with no friction.

Log

Record silently for visibility and tuning.

Justify

Ask for a business reason before sending.

Verify

Ask the user to confirm sensitive content.

Three ways to handle AI risk. One keeps the data private.

Ban AI tools

  • Use moves to personal devices
  • No visibility into what was shared
  • Lost productivity

Route through a proxy

  • New traffic path to run and scale
  • Sees destinations, not data meaning
  • Prompts leave the device for inspection

Sentra in the browser

  • Classification on the device
  • Policies by app and data class
  • Original content never sent to Sentra
