The short version

  • Each has a real cost: Rhombus Systems the per-camera annual licence never ends and a camera without an active licence stops working, so the total cost over a ten-year hardware life is several times the hardware price.; Tenable pricing starts at $3500/year for Tenable One VM, expensive for small organizations
  • They diverge on capability: Rhombus Systems covers On-camera storage, Tenable covers Unified attack surface mapping.

Where each one falls short

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

Rhombus Systems

  • The per-camera annual licence never ends and a camera without an active licence stops working, so the total cost over a ten-year hardware life is several times the hardware price.
  • Cameras must be Rhombus, so there is no reuse of existing IP cameras and migrating away means replacing every device rather than changing software.
  • Cloud archiving is priced separately by retention and stream count, and long retention on multisensor cameras runs into five figures per camera, which can dwarf everything else in the quote.
  • On-camera storage is the default retention, so a camera physically stolen or destroyed takes its unarchived footage with it unless cloud archiving was paid for on that camera.
  • Analytics and integrations are good for mid-market needs but shallower than a dedicated enterprise VMS with a large third-party ecosystem, so specialist requirements like advanced LPR or forensic search hit limits.

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
