Use case · AI access control

Allow the AI you trust. Block the rest, by rule.

Enable AI adoption without blanket blocking: define which providers are sanctioned per department and destination, and enforce it in the browser and on the gateway with the reason shown.

Detections by department and destination with block outcomes.
The problem

Blanket blocking harms productivity. Open access creates risk.

AI access control

Unsanctioned and non-EU AI in daily use.

The challenge

Teams adopt whichever assistant is fastest, including providers outside the EU or outside your contracts, often through personal accounts.

Why existing controls miss it

Network controls block or allow a domain; they cannot apply different rules to different departments and data, or explain the decision to the user.

How Deltawall enforces it

Rules per department and destination allow sanctioned, EU-resident tools and block the rest. The user sees the reason, and the same rule set applies to API traffic through the gateway.

  • A ready rule to block non-EU AI
  • EU-first provider allow-list on the gateway
  • Desktop AI apps governed through MDM bundles

Questions

What buyers ask.

Can we allow ChatGPT for one team and block it for another?

Yes. Rules combine department and destination, so the same site can be allowed, warned or blocked per department.

Does the user know why something was blocked?

Yes. The banner states the rule and the reason. There are no silent failures.
