Pricing

Optics is free. Gate is $499. Phantom Engine is $799 a node.

Built for teams that put agents to work and still want humans holding the keys. You are buying three different jobs: egress telemetry without the conversation, live decisions on that path, and runtime enforcement on Linux you enroll. Phantom Engine Enterprise adds the ledger and dual-control when proof has to travel with the work.

Vantio Optics

Observe · Free

Runs in your process

Watch where agents connect when they call LLM APIs — egress telemetry you can replay, without reading conversations. Never steers, never blocks, never stores prompts or completions. Free forever; included when you buy Gate or Phantom Engine. Wrap coverage is listed below and in docs.

  • ·Live watch on LLM and agent outbound paths
  • ·Egress telemetry only — never prompts
  • ·Node fetch, undici, http/https, http2, net/tls, WebSocket, spawned curl/wget · Python urllib, http.client, sockets, requests/httpx/aiohttp/urllib3, spawned curl/wget
  • ·Browser paths stay outside this wrap

Vantio-hosted control plane · trial via hello@ today

$499/ month

Write policy as code, preview it on live traffic, then turn it on so Gate can allow, block, or redact PII — on the same wrap Optics watches, including Node http2, net/tls, WebSocket, and spawned curl or wget, not only global fetch. Public list $499/mo after a 14-day trial. Includes Optics. A peer product for teams that need enforce without taking a host under Phantom Engine.

  • ·Everything in Optics
  • ·Destination blocking, PII redaction, and spend limits — on the Node and Python wrap
  • ·Preview before you enforce for real
  • ·Browser paths and processes that never load the wrap still need Phantom Engine on hosts you enroll

$799/ node / month

A host stop on Linux you enroll, at $799 per node. Dangerous file and network moves can fail even when the process skipped the wrap. Includes the enforce plane on that host; do not stack Gate cloud $499 on this quote. Phantom Engine Enterprise adds the ledger, evidence, and dual-control — talk to sales toward about $2,000 per node.

  • ·Enforce plane ships with the node — one purchase
  • ·Runtime control on hosts you enroll

Explore Phantom Engine

Optics, Gate, and Phantom Engine are peer products. Do not put Gate cloud ($499) on a Phantom Engine or Phantom Engine Enterprise node quote. Phantom Engine Enterprise governance is talk to sales via sales@vantio.ai.

Pricing questions

Certifications, install, and product differences live on Support.

Is Vantio Optics free?
Yes. Vantio Optics is free forever and included when you buy Gate or Phantom Engine.
What does Vantio Gate cost?
Vantio Gate is publicly listed at $499 per month after a 14-day trial. Start a trial via hello@vantio.ai. Gate stays its own product for enforce-only buyers who are not taking a host under Phantom Engine.
What does Phantom Engine cost?
Phantom Engine is $799 per governed node per month. That buy is a host stop plus enforce on Linux you enroll — one purchase for that host. Do not stack Gate cloud $499 on a Phantom Engine quote.
How is Phantom Engine Enterprise priced?
Phantom Engine Enterprise adds governance — ledger, evidence, and dual-control — on the same protection. It is talk to sales, toward about $2,000 per governed node per month.

Why Phantom Engine is quoted per node

Priced against flying blind on the hosts you run — not another dashboard seat.

Phantom Engine is priced per governed node because the stop lives on that host. The $799 list is one purchase for that machine — not Gate cloud stacked on top.
