Where each one falls short

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

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.

Zscaler Internet Access

  • The pricing page names two base tiers, Essentials Platform and Zscaler Platform, plus modular add ons including three Digital Experience Monitoring tiers, but publishes no dollar figures anywhere and routes buyers to a demo request for cost
