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- Pricing is unpublished and consistently at the top of the market, and organisations that need only one capability, a board portal or an audit analytics tool, generally pay less and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
Terraform
- HCL syntax requires learning a domain-specific language with limited GUI alternatives
- State file management is complex, especially at scale with multiple workspaces
- terraform import workflow is fiddly and must be done one resource at a time
- No native error handling or try-catch capabilities like traditional programming languages
- No automatic rollback capability - must manually delete and re-run if needed

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.
Terraform: Is there a free tier?
Yes. The free tier supports up to 500 managed resources and 1 concurrent run. The legacy free tier ends March 31, 2026; remaining organizations auto-convert to the enhanced free tier.
SourceDiligent: 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.
Terraform: What clouds does Terraform support?
Terraform supports AWS, Microsoft Azure, Google Cloud Platform, Oracle Cloud, Docker, and HashiCorp's own HCP Terraform managed service, with over 2000 providers available.
SourceDiligent: 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.
Terraform: Do I need HCP Terraform Cloud or can I run locally?
Terraform runs locally by default, storing state on your machine. For team collaboration and production use, remote backends like S3, Azure Storage, or HCP Terraform are recommended for locking and security.
SourceDiligent: 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.
Terraform: Is HCL hard to learn?
HCL is designed to be human-readable and sits between JSON and YAML. It supports comments, variables, functions, and conditional logic. While beginners can get started quickly, mastering advanced features takes practice.
