Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Resolver
- Kroll ownership since 2022 means the product is sold alongside risk consulting services, so buyers who want software with no services attach should expect that conversation and should price the licence separately in negotiation.
- Configuration flexibility comes at the cost of implementation time, with deployments commonly running several months and typically requiring vendor or partner services, so the first-year cost is well above the annual licence.
- Module-based pricing means the platform gets expensive quickly once you add audit, compliance and continuity to a security-led purchase, and modules bought later rarely carry the discount of the original deal.
- The IT and cyber compliance side is thinner than dedicated tools, so organisations chasing SOC 2 or ISO 27001 evidence automation will find it does not replace a Drata or Vanta.
- Reporting is capable but the drag and drop builder has a real learning curve, and organisations that do not train an internal administrator end up raising support tickets for changes that should be self-service.
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
