Where each one falls short

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

Euna Solutions

  • The suite is assembled from six or more separate acquisitions and integration between modules is still being completed, so a buyer purchasing two modules should ask precisely what data passes between them today rather than on the roadmap.
  • No pricing is published at any level and terms are typically multi-year, so budgeting the true cost requires obtaining peer jurisdiction contracts, which is possible but slow.
  • Individual modules face specialists with deeper functionality, so a jurisdiction buying only procurement or only budgeting may get less capability than from a single-product vendor at similar cost.
  • Ownership has changed twice in six years, from a SPAC to private equity, and further change is plausible, which creates roadmap uncertainty over the length of a typical multi-year public sector contract.
  • Grant management depth is oriented to United States federal and state programmes, which makes the product close to useless to public bodies outside that funding system.

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
