Deltawall
AI gateway

The same policy for the traffic a browser never sees.

Apps, scripts and agents call AI through an OpenAI-compatible endpoint with keys you issue. The gateway applies your policy, redacts payloads before they reach a provider, and writes to the same evidence log.

Deltawall telemetry: gateway and browser volume by outcome with a live tail of events.
Use case

Developer and API governance.

The gateway

Policy for machine-to-model traffic.

The challenge

Internal tools, scripts and AI agents send prompts to model APIs directly. They carry the same customer data as a person's prompt, with no browser in the path.

Why existing controls miss it

Browser controls cannot see server-side API calls, and provider consoles offer no organisation-wide data policy.

How Deltawall enforces it

Route AI calls through the gateway on keys you issue. Each key carries a policy; payloads are redacted before the provider sees them, and non-EU providers can be blocked per department.

  • OpenAI-compatible, so existing SDKs work
  • Streaming responses supported
  • Every call lands in the evidence log
Providers

EU first, by rule.
