Where each one falls short

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

LogicManager

  • The flat fee is quoted per organisation and not published, so the pricing model that makes LogicManager attractive still cannot be compared without a sales process.
  • Configuration depth means the taxonomy has to be designed properly before rollout, and organisations that skip that step end up with a structure that cannot answer the linkage questions the tool exists to answer.
  • Reporting and dashboarding are functional rather than flexible, and teams wanting bespoke board reporting commonly export to Power BI, which reintroduces the manual step they were removing.
  • Quantitative risk modelling is limited compared with specialist tools, so organisations needing Monte Carlo style loss simulation will need something else alongside it.
  • The user interface is dated relative to newer compliance automation tools, and infrequent business users often need repeat training, which erodes the participation benefit that unlimited licensing is supposed to deliver.

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
