The short version

  • Each has a real cost: EcoStruxure Geo SCADA Expert the ClearSCADA name is retired, so the large body of documentation, forum answers and integrator experience under that name is increasingly stale and does not always match current behaviour.; 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: EcoStruxure Geo SCADA Expert covers Point-banded server licence, 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.

EcoStruxure Geo SCADA Expert

  • The ClearSCADA name is retired, so the large body of documentation, forum answers and integrator experience under that name is increasingly stale and does not always match current behaviour.
  • Licensing is point-banded and client-counted with nothing published, and discount depends on your existing entitlement, so a first-time buyer negotiates from a weaker position than an incumbent renewing.
  • The free development mode is capped at 1,000 points and two hours of runtime, which is enough to prototype a screen but not enough to load-test a realistic network before you commit.
  • It is a Windows Server product; there is no Linux server option, so the operating system licensing, patching cadence and hardening burden come with the platform whether you want them or not.
  • Schneider has repeatedly rebranded and repositioned this line, from Control Microsystems to ClearSCADA to EcoStruxure Geo SCADA Expert, which makes long-horizon roadmap commitments hard to trust for a system a utility expects to run for fifteen years.

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

EcoStruxure Geo SCADA Expert: Can I still buy ClearSCADA?

No. The product is sold as EcoStruxure Geo SCADA Expert. ClearSCADA is a retired name and current quotes will use the new one.

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.

EcoStruxure Geo SCADA Expert: How is the server licensed?

By point count, in bands starting around 250 points and scaling to over a million on a single server. Clients are licensed on top, individually or in bundles.

Trimble Unity Maintain: Do I need Esri ArcGIS?

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

EcoStruxure Geo SCADA Expert: Is there a way to test it for free?

Yes, unlicensed development mode runs up to 1,000 points for two hours at a time. That is a prototyping tool, not a pilot.

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.

EcoStruxure Geo SCADA Expert: Is Geo SCADA the same as AVEVA Plant SCADA?

No. Plant SCADA is the former Citect product for plant-floor supervisory control. Geo SCADA is the former ClearSCADA product for distributed telemetry. Different codebases, different problems.

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.
