Where each one falls short

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

NEXGEN Asset Management

  • Pricing keys off asset count, so a routine GIS resegmentation that splits mains into more records can raise your subscription without adding a single user or work order.
  • Nothing is published and the vendor is small, so the reference set you can call is limited and mostly Californian and North American public agencies.
  • The interface is dated compared with modern CMMS products, which hurts adoption among field crews who compare it to consumer apps on their own phones.
  • GIS integration is the product strength and also its dependency; agencies without a maintained ArcGIS asset layer face a data preparation project before NEXGEN is useful.
  • As a small vendor it carries acquisition risk, and in this segment acquisitions have repeatedly meant a product frozen while it is folded into a larger portfolio.

Tenable

  • Pricing starts at $3500/year for Tenable One VM, expensive for small organizations
  • Many enterprise features require custom quote and sales engagement
  • Cloud Exposure, OT Exposure, and other modules have no published pricing
  • Multi-year contracts common, limiting flexibility
  • Setup and configuration complexity for enterprise deployments
