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- Pricing is unpublished and consistently at the top of the market, and organisations that need only one capability, a board portal or an audit analytics tool, generally pay less and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.
Splunk Enterprise Security
- Splunk Enterprise Security is licensed separately from the Splunk platform, so a SIEM deployment needs both
- Splunk publishes no rate for Enterprise Security and directs buyers to contact a pricing expert
- UEBA, SOAR and automated threat analysis require the Premier edition rather than Essentials
- The platform underneath can be billed by ingest volume, workload or activity, so the total cost depends on a pricing model chosen at contract time rather than a list price
