Where each one falls short

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

Clariti

  • Salesforce platform licences sit underneath the subscription and are not always visible in the initial quote, so the fully loaded cost can be materially higher than the comparison against Accela or Tyler suggests.
  • Building on Salesforce means the agency inherits Salesforce release cycles and pricing changes, neither of which Clariti controls.
  • It has far less accumulated edge case handling than the incumbents, so unusual fee schedules, historic district rules or state mandated reporting can become configuration projects.
  • Professional services dominate the first year cost, as with every permitting implementation, and agencies that budget only for licence are the ones whose projects stall.
  • The install base is smaller than Accela or Tyler, so there are fewer peer agencies to call for reference and fewer trained implementation consultants in the market.

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
