Where each one falls short

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

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

Verint

  • Thoma Bravo took Verint private in November 2025 and is combining it with the directly competing Calabrio, so buyers signing multi-year agreements now cannot know which of the two overlapping product lines survives as the strategic one.
  • The catalogue is licensed piece by piece, including individually priced automation bots, so the quoted platform figure is rarely the figure you end up paying once the analytics, recording and bot modules are all in scope.
  • Implementations routinely run six to twelve months and effectively require a partner, which means the first year of a contract is spent paying for software that is not yet delivering.
  • The interface reflects two decades of accumulated enterprise features, and new supervisors need formal training to do things that a mid-market tool exposes in one screen.
  • It is priced and scoped for thousands of agents, so a 300-seat operation gets an enterprise contract, an enterprise implementation and enterprise complexity for a problem a lighter product would solve in weeks.
