The short version
- Only Keycloak has a free tier, so it costs nothing to try first.
- Each has a real cost: Keycloak requires self-hosted deployment and operational expertise to install, configure and maintain; 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.

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
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.
