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.; Fortinet FortiGate security services are sold as separate FortiGuard subscription bundles, so ATP, UTP and ENT determine which protections are actually active
  • They diverge on capability: Diligent covers Diligent Boards, Fortinet FortiGate covers Next-generation firewall.
  • 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  • Pricing is unpublished and consistently at the top of the market, and organisations that need only one capability, a board portal or an audit analytics tool, generally pay less and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.

Fortinet FortiGate

  • Security services are sold as separate FortiGuard subscription bundles, so ATP, UTP and ENT determine which protections are actually active
  • Throughput is tied to the appliance model, from 500 Mbps on the FortiGate 30G to 520 Gbps on the 7121F, so capacity planning is a hardware purchase
  • Pricing is not published and goes through partners
