Where each one falls short

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

mySidewalk

  • It produces analysis and presentation rather than operational change, so the value has to be re argued at every renewal against services with more visible outputs.
  • Budget frequently comes from a grant, which means the subscription is exposed when the grant cycle ends rather than being protected as core infrastructure.
  • The prewired datasets are American, so the platform has effectively no value outside United States federal statistical sources.
  • Analytical depth is bounded by what the platform exposes, so an agency with a genuine analyst will hit the ceiling and move to a statistical environment.
  • Small area estimates remain small area estimates, and presenting them as polished dashboards can lend unwarranted confidence to figures whose error bars overlap.

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
