How Deltawall keeps sensitive data out of AI tools.

Deltawall works inside the browser your people already use. Nothing to reroute, nothing to decrypt.

The Insights page of the Deltawall console: in the last 30 days, sensitive data met an AI tool 160 times, and 8 of 11 people are covered.

What happens when someone pastes sensitive data.

  • A contract pasted in for a quick summary.

  • A customer list uploaded to build a report.

  • An API key shared to fix a bug.

Blocking AI costs you the productivity. Allowing it blind costs you the data.

Detect

Sensitive data is spotted as people type, paste or upload.

The Activity page of the Deltawall console: the last 30 days, with 79 blocked and 56 redacted, and a bar chart per day.

Protect

Your policy decides: allow, warn, mask or block. The user always sees why.

The Policies page of the Deltawall console: the rules in the order they run. Two rules block, for example API keys and credentials, and one redacts bank account numbers.

Prove

Every decision is on record. Your auditor can verify it without trusting us.

The Evidence page of the Deltawall console: a log of events, each with its number, its time, its outcome (blocked, redacted, recorded, allowed or warned) and a label for what was sent, such as a prompt with an AWS key.

Works in ChatGPT, Microsoft Copilot, Claude, Gemini, Perplexity and DeepSeek.

Protection at three levels.

  • PeopleReady

    Stopped before it is sent.

    Sensitive data is caught in the browser and masked before it reaches ChatGPT, Copilot or Gemini.

  • Company computersReady

    Shadow AI, made visible.

    See which AI tools are in use, including the ones IT never approved. Keep the approved ones and block the rest, desktop apps included.

  • AI agentsIn the pipeline

    Agents with an identity and limits.

    Every AI agent gets a verified identity and short-lived access to only what its task needs.

One console for all three, with the same audit evidence.

What Deltawall protects

Each type is a switch in your policy, per department and per AI tool.

  • Personal data. Names, postal addresses, dates of birth, BSN and other national ID numbers, health information.

  • Financial data. IBANs and account numbers, card numbers, VAT and KVK numbers.

  • Secrets. API keys, credentials, private keys, access tokens and cloud keys.

  • Company confidential. Source code and confidential company information.

How Deltawall differs from legacy data-loss tools

Deltawall compared with legacy data-loss tools
Legacy data-loss toolsDeltawall
What the vendor seesOften the full content of every promptNever the content: labels and metadata only
Employee privacyOften monitoring by personReports by department, never by person

The Deltawall column describes protection in the browser. The legacy column describes typical network and endpoint DLP; individual products differ.
