The short version

  • Each has a real cost: 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.; Trimble Unity Maintain esri ArcGIS is a hard prerequisite, so an organisation without it faces a second substantial licence and a GIS programme before the maintenance system can be used at all.
  • They diverge on capability: HID Global covers Physical access readers, Trimble Unity Maintain covers Built on ArcGIS.
  • 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.

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.

Trimble Unity Maintain

  • Esri ArcGIS is a hard prerequisite, so an organisation without it faces a second substantial licence and a GIS programme before the maintenance system can be used at all.
  • The product is mid-rename from Cityworks to Trimble Unity Maintain with transition timelines Trimble has not committed to publicly, leaving contracts, documentation and integrator experience split between two names.
  • CVE-2025-0994, a deserialisation flaw in Cityworks, was exploited in the wild and listed by CISA in February 2025, which makes on-premise deployments a patching obligation rather than a set-and-forget install.
  • Because assets live in the GIS, changing the asset model is a GIS division change, so maintenance teams cannot restructure their own hierarchy without another department in the loop.
  • It is built for North American public sector practice, and the permitting, funding source and reporting models do not map cleanly onto other countries or onto private industrial estates.

Answered from the vendors’ own pages

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.

Trimble Unity Maintain: Is Cityworks discontinued?

Not discontinued, renamed. It is becoming Trimble Unity Maintain, converging with AgileAssets, and Trimble has not published a final transition date.

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.

Trimble Unity Maintain: Do I need Esri ArcGIS?

Yes. The product is built on ArcGIS and cannot be deployed without an Esri licence.

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.

Trimble Unity Maintain: Was there a security incident?

Yes. CVE-2025-0994 in Cityworks was exploited in the wild and added to the CISA known exploited vulnerabilities catalogue in February 2025.

Trimble Unity Maintain: Can it handle roads and pavement as well as pipes?

Yes, through the AgileAssets lineage now inside the Unity Maintain family, which adds linear referencing for transportation assets.
