The short version

  • Each has a real cost: GNAT Pro no pricing published on website; requires contacting AdaCore directly for quotes; HID Global sales run through integrators, so the price you get depends on which partner quotes it and there is no published list to negotiate against.
  • Prices and features above were last checked on 1 September 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

HID Global

  • Sales run through integrators, so the price you get depends on which partner quotes it and there is no published list to negotiate against.
  • Mobile credentials are charged per identity as an ongoing fee, which converts a one-off card cost into a recurring per-employee subscription that budgets rarely anticipate.
  • Large estates run mixed generations of readers, so a credential upgrade is a multi-year hardware programme and the software licence is a small fraction of the true cost.
  • Legacy credential technologies still widely deployed have documented cloning weaknesses, and HID commercial interest in selling the replacement does not remove your exposure in the interim.
  • The portfolio spans hardware, firmware and several acquired software products, so integration between HID own components is less consistent than the single-vendor pitch implies.

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
HID Global: Do we have to replace readers to use mobile credentials?

Often yes, at least in part. Reader capability determines which credential technologies work, and that hardware cost dominates the business case.

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
HID Global: Are mobile credentials cheaper than cards?

Not necessarily. Cards are a one-off cost per employee, mobile identities are typically a recurring charge, so the crossover depends on staff turnover.

HID Global: Can we buy directly from HID?

Generally not for access control deployments. Products are sold and installed through channel partners, so partner selection is part of the buying decision.
