The short version

  • Each has a real cost: Diligent the platform is an assembly of acquisitions, with the analytics engine from ACL, risk from Rsam, ethics and third-party diligence from Steele and the board portal from Diligent itself, so cross-module reporting and consistent user experience should be tested in a proof of concept rather than assumed.; 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.
  • They diverge on capability: Diligent covers Diligent Boards, Resolver covers Incident management.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Diligent

  • The platform is an assembly of acquisitions, with the analytics engine from ACL, risk from Rsam, ethics and third-party diligence from Steele and the board portal from Diligent itself, so cross-module reporting and consistent user experience should be tested in a proof of concept rather than assumed.
  • Pricing is unpublished and consistently at the top of the market, and organisations that need only one capability, a board portal or an audit analytics tool, generally pay less and get more from a specialist.
  • Renewal leverage is weak once the board portal is embedded, because directors are the least willing user group to be migrated and that dependency is well understood by the vendor at renewal time.
  • The analytics engine expects real data skills, and audit teams without an analytics-capable member typically use a fraction of what they licensed while paying for all of it.
  • Module-by-module implementation means the promised single view of governance and risk usually arrives years after the first purchase, if the later modules are ever funded.

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.

Answered from the vendors’ own pages

Diligent: Is Diligent One the same product as Galvanize?

It contains it. Diligent bought Galvanize, the ACL and Rsam merger, for around one billion dollars in April 2021, and its audit analytics and risk modules are that heritage rebranded into Diligent One.

Resolver: Who owns Resolver?

Kroll, which acquired it in 2022. It is marketed as a Kroll business and sold alongside Kroll risk and investigations services.

Diligent: What does Diligent cost?

Not published. It is quoted by module and user, and board portal seats are priced differently from GRC seats. Expect an annual or multi-year enterprise agreement.

Resolver: What does Resolver cost?

Pricing is not published. It is quoted by module and user count on an annual or multi-year enterprise agreement, with implementation charged separately.

Diligent: Can you buy just the board portal?

Yes, Diligent Boards is sold on its own and is the most common entry point. The GRC modules are separate purchases.

Resolver: Is Resolver a SOC 2 compliance tool?

No. It is a risk, incident and investigations platform. Automated evidence collection for security certifications is not its strength.

Diligent: Does it replace a SOC 2 automation tool?

No. Diligent is aimed at enterprise audit, risk and governance, not at automated evidence collection for security certifications.

Resolver: How long does implementation take?

Months rather than weeks for a multi-module deployment, and most customers use vendor or partner services to configure it.
