Where each one falls short

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

Omada Identity

  • Pricing is per managed identity, so organisations with large numbers of contractors, service accounts or seasonal staff pay governance fees on identities nobody is really governing.
  • It governs access but provides no single sign-on, multi-factor authentication or privileged session management, so it is always a second or third identity subscription rather than a consolidation.
  • The fast-deployment promise depends on accepting its standard process model; organisations with genuinely unusual entitlement structures end up in custom work and the timeline advantage disappears.
  • Connector coverage is strong for mainstream enterprise systems and thin for bespoke or industry-specific applications, and each custom connector is a project with ongoing maintenance.
  • Data quality in the HR system determines whether joiner mover leaver automation works, so companies with messy HR records find the tool exposes that problem rather than solving 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
