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.; One Identity the portfolio is assembled from separate acquisitions, so components are separately licensed, separately administered and do not present one console, which raises operational cost.
  • They diverge on capability: Diligent covers Diligent Boards, One Identity covers Identity Manager.
  • Prices and features above were last checked on 1 September 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  • Pricing is unpublished and consistently at the top of the market, and organisations that need only one capability, a board portal or an audit analytics tool, generally pay less and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.

One Identity

  • The portfolio is assembled from separate acquisitions, so components are separately licensed, separately administered and do not present one console, which raises operational cost.
  • Identity Manager implementations are customisation-heavy and commonly run over a year, with the services spend exceeding the licence cost in the first year.
  • Quest has changed private equity ownership more than once since the Dell separation, and buyers should ask directly about product investment commitments before signing a multi-year deal.
  • Product documentation and support sit behind a customer portal, which makes independent evaluation before purchase harder than with vendors that publish openly.
  • The cloud-native and developer experience trails the pure-play identity vendors, so organisations moving decisively to SaaS applications find the on premises heritage becomes a constraint rather than an asset.

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.

One Identity: Is One Identity the same company as Quest?

Yes. One Identity is Quest Software's identity and access management business unit, not a separate vendor.

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.

One Identity: Does it include privileged access?

Safeguard provides it, but it is licensed separately from Identity Manager. Neither includes the other.

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.

One Identity: Why choose this over SailPoint or Saviynt?

Almost always because of Active Directory depth via Active Roles or an appliance requirement for privileged sessions. For cloud-first estates the specialists are the stronger choice.

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.
