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.; KnowBe4 published prices assume a three year term, so the quoted per seat rate depends on a long commitment
- They diverge on capability: Diligent covers Diligent Boards, KnowBe4 covers Security awareness training.
- 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- Pricing is unpublished and consistently at the top of the market, and organisations that need only one capability, a board portal or an audit analytics tool, generally pay less and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.
KnowBe4
- Published prices assume a three year term, so the quoted per seat rate depends on a long commitment
- Pricing is banded by seat count, and the lowest band of 25 to 50 seats pays the highest rate
- Accounts above 1,000 seats have no published price and require a custom quote
- Third party integrations, Compliance Plus and PhishER Plus are all separately priced per seat add ons
- The Foundation tier carries 200 training modules against more than 1,000 on Advanced, so content volume is the main gate
