Where each one falls short

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

BeyondTrust

  • The product lines came from separate origins and still have separate consoles, so buying the suite does not deliver the single pane of glass the bundle implies.
  • Licensing metrics differ between products, per managed account, per endpoint, per concurrent session, which makes multi-product quotes hard to compare with competitors and hard to forecast as you grow.
  • Self-hosted deployments carry real infrastructure and upgrade burden, and organisations without a dedicated PAM administrator find the system drifts out of maintenance.
  • Endpoint privilege management requires sustained rule authoring as applications change, so the first-year saving in helpdesk tickets erodes if nobody owns the policy afterwards.
  • Discovery finds far more privileged accounts than most organisations expect, which is valuable but converts a licence purchase into a longer remediation programme before the control is real.

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
