Where each one falls short

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

Genetec Security Center

  • Genetec publishes no pricing and sells only through certified integrators, so buyers cannot benchmark a quote and the same 500-camera design can vary widely in price between integrators.
  • Genetec Advantage is an annual maintenance agreement commonly quoted at 18 to 22 percent of licence value, so a perpetual licence is not a one-off cost, and letting it lapse freezes the system on its current version and stops support.
  • Licensing is per camera channel, so adding cameras is a licence purchase every time and organisations that expand a site by a hundred cameras discover the software line grows in step with the hardware.
  • It is a Windows server platform that has to be sized, patched, backed up and eventually migrated, so the real cost includes an IT estate and an integrator, which puts it out of reach of organisations without a security team.
  • Operator competence is a genuine dependency: Security Desk is dense, and sites that deploy it without training end up using a fraction of the platform they paid for while still paying full maintenance on all of it.

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
