Where each one falls short

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

Nessus

  • Nessus Professional is $4,790 for one year, with no free or low cost commercial tier
  • Multi year terms are the only discount route, at $9,330.95 for two years and $13,637.54 for three
  • It is a single user scanner, so team workflows mean migrating to another Tenable product
  • Tenable One vulnerability management is priced separately, starting at $3,500 a year for 100 assets

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.
