ChatGPT Enterprise, Custom GPTs and Codex

Let your Custom GPTs reach company data safely.

Internal GPTs send API requests to internal systems. AvertGate moves those requests along under your rules: unauthorized access stops while correct use flows without slowing down.

Controlled access

No more uncontrolled requests to internal databases.

A Custom GPT’s Actions call HTTP APIs. AvertGate steps in between; which endpoint and which arguments are allowed is written in your policy.

  • Read queries are open, deletes and updates are controlled
  • Outbound calls to internal network addresses are blocked
  • An endpoint that is not listed does not run

Data protection

Keep customer data out of GPT replies.

Personal data and API keys are caught and masked in tool call arguments. Raw data never leaves the agent’s scope.

  • Card, ID and email patterns are masked
  • Slow leaks are tracked across the whole session
  • Masked fields are visible in the record

Codex

Let coding agents work without losing speed.

Codex and similar coding agents work with the repo, shell and deploy keys. Tests and reads are open; going live is put to a person.

  • Secret files stay outside the agent’s view
  • Pushes to a protected branch need manager approval
  • Every command on record

Frequently asked

Are Custom GPT Actions covered too?

Actions call HTTP APIs, so they run through the same policy via the HTTP reverse proxy. Connectors that use MCP connect through the MCP proxy.

Is our data sent to AvertGate?

No. The gateway runs on your network. Tool arguments, results and file contents never leave it; only redacted event data reaches the dashboard.

Will it slow our agents down?

Everyday reads and queries flow with a few milliseconds of added latency on average. Only risky actions are put to a person.
