Where each one falls short

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

Keycloak

  • Requires self-hosted deployment and operational expertise to install, configure and maintain
  • No managed cloud option provided by Red Hat; organisations must operate infrastructure themselves or use third-party distributions
  • Clustering and high-availability configurations require additional operational knowledge
  • Community support only; commercial support requires third-party vendors or distributions

Rapid7 InsightVM

  • InsightVM is now sold inside Exposure Command rather than as a standalone product
  • Rapid7 states pricing is not publicly listed and is provided by custom quote based on the customer's environment
  • Billing counts billable assets including devices, software, identities, cloud compute instances and applications, so the asset count grows faster than a device inventory suggests
  • Cloud security, compliance, infrastructure as code scanning and application security testing require the Ultimate package rather than Essentials
  • Volume discounts are described as commonly available for larger asset counts, so smaller buyers pay the higher unit rate
