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.; HashiCorp Vault policies are written in HCL with no graphical user interface for policy management or editing
  • They diverge on capability: Diligent covers Diligent Boards, HashiCorp Vault covers Secret storage.
  • 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  • Pricing is unpublished and consistently at the top of the market, and organisations that need only one capability, a board portal or an audit analytics tool, generally pay less and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.

HashiCorp Vault

  • Policies are written in HCL with no graphical user interface for policy management or editing
  • Unsealing requires managing multiple key shares and coordinating a quorum of operators
  • Community Edition lacks enterprise features like namespaces and disaster recovery replication
  • Requires additional monitoring solutions for alerting and observability

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.

HashiCorp Vault: Does HashiCorp Vault have a free version?

Yes. The open-source Community Edition is completely free and includes core secrets management, dynamic secrets, and encryption as a service. It is self-hosted with no licensing fees or secret count limits, but lacks enterprise features like namespaces, disaster recovery replication, and Sentinel policies.

Source
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.

HashiCorp Vault: Can I use HashiCorp Vault in production?

The Community Edition is suitable for non-production environments and small teams. For production deployments, organizations typically use HCP Vault Dedicated (managed cloud service starting at approximately 22 USD per month) or Vault Enterprise with custom pricing that includes disaster recovery, performance replication, and 24/7 support.

Source
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.

HashiCorp Vault: What are the main integrations available?

Vault integrates with AWS, Azure, Google Cloud, Active Directory, Okta, and 80+ other platforms. It supports dynamic credential generation for cloud providers, database systems, and identity services, enabling centralized secret management across multi-cloud infrastructure.

Source
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.

HashiCorp Vault: Does Vault work offline?

Vault requires network connectivity to function as it is a centralized secrets management server. However, it can be deployed on-premises for air-gapped environments, and clients can cache short-lived tokens for temporary offline access once authenticated.
