The short version

  • Each has a real cost: GNAT Pro no pricing published on website; requires contacting AdaCore directly for quotes; Teleport pricing is not published and is described as active users plus protected resources, so an autoscaling estate cannot forecast the bill and finance teams discover the true cost only after the first true-up.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

GNAT Pro

  • No pricing published on website; requires contacting AdaCore directly for quotes
  • Vendor indicates per-user, per-year subscription model but does not disclose specific costs

Teleport

  • Pricing is not published and is described as active users plus protected resources, so an autoscaling estate cannot forecast the bill and finance teams discover the true cost only after the first true-up.
  • The proxy is a hard dependency on reaching production, so it needs its own high availability deployment and a tested break-glass path or an outage in Teleport becomes an outage in your ability to respond to outages.
  • The open source Community Edition omits Access Requests, Device Trust and the FIPS builds, which are exactly the controls an auditor asks about, so the free tier rarely survives a compliance review.
  • Self-hosting means running and upgrading a certificate authority and its backing store, and Teleport releases frequently enough that upgrade work becomes a standing operational commitment.
  • Coverage across protocols is uneven in depth, so teams with legacy systems, unusual databases or bespoke network appliances find gaps that still require the old VPN to remain in place alongside it.

Answered from the vendors’ own pages

GNAT Pro: How much does GNAT Pro cost?

GNAT Pro pricing is not published on the website. Customers must request a pricing quote by contacting AdaCore directly or speaking with a GNAT Pro expert.

Source
Teleport: Is the open source edition usable in production?

Yes, but it lacks Access Requests, Device Trust and FIPS builds, which most compliance programmes end up requiring.

GNAT Pro: What is GNAT Pro licensing model?

GNAT Pro is sold on a per-user, per-year basis with no license locks. Customers can request pricing for their specific needs.

Source
Teleport: How is it priced?

Not publicly. The vendor prices on active users and protected resources and provides a quote after a sales conversation.

Teleport: What happens if Teleport goes down?

Nobody reaches the resources behind it, so you need a highly available deployment and a documented break-glass procedure.

Teleport: Does it replace our VPN?

For anything you put behind it, yes. Legacy systems and appliances it does not support will keep the VPN alive.
