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.; Vanta no published pricing for any tier; all plans require requesting a demo and contacting sales

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Pricing is unpublished and consistently at the top of the market, and organisations that need only one capability, a board portal or an audit analytics tool, generally pay less and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.

Vanta

No published pricing for any tier; all plans require requesting a demo and contacting sales
Essentials tier limited to one compliance framework; organisations needing multiple frameworks must upgrade to higher tiers
Plus and Professional tiers feature unclear differentiation; specific pricing and included questionnaires not published
Enterprise pricing fully custom; no transparency on costs or what features are included
AI questionnaire automation capped at 25 annually in Plus tier, only 144 annually in Professional tier
