Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Ping Identity

  • Workforce pricing carries a 5,000 user annual minimum, so an organisation with 800 staff pays for 5,000 and the effective per user cost is over six times the list rate.
  • Adaptive multi-factor authentication is in the Plus tier only, doubling the per user price for a capability many buyers assume is standard in a modern identity platform.
  • ForgeRock no longer exists as an independent product, so customers who chose it specifically to avoid Ping now face a roadmap set by the vendor they did not pick.
  • Thoma Bravo ownership across both merged companies means the commercial priority is margin, and buyers report firmer renewal negotiations than they saw before 2022.
  • The portfolio has overlapping components from three product lineages, so scoping a deployment requires vendor architects and the licensing conversation is more complicated than the price list implies.

Tenable Nessus

  • Nessus Professional is $4,790 for one year, sold as an annual licence rather than a per scan or usage based fee
  • Support beyond the base entitlement costs an extra $400 per year for Advanced Support with 24x365 phone and chat access
  • The on demand training course is a separate $275 purchase for a single person for one year
  • Multi year discounts require paying for two or three years up front
