Security teams who cannot send the tree to a public LLM

The Tabnine air-gap stack

n8n stays inside the VPC, Llama plans the CVE fix, Tabnine patches locally. Not Cursor on the public API.

Who owns what

  1. n8n

    The alert — SAST in, internal git out. Not the AST and not egress.

    Try n8n (opens in a new tab)

  2. Llama

    The plan — vuln vector, what to change. Not the IDE keystrokes.

    Try Llama (opens in a new tab)

  3. Tabnine

    The patch — local index, tests, no telemetry. Not the scanner.

    Try Tabnine (opens in a new tab)

How to use this stack

  1. On-prem SAST hits self-hosted n8n. The tree does not leave the VPC.
  2. Llama on the private cluster writes the remediation plan. Not Claude in the cloud.
  3. Tabnine applies it in the isolated workspace and generates tests.
  4. n8n commits to the internal remote. This is not the 2026 coding stack.
