Where each one falls short

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

ArchiveSocial

  • Coverage depends entirely on third party platform APIs, so when a network restricts or reprices its API the archive's completeness changes for reasons the vendor does not control.
  • Pricing scales with the number of archived accounts, so an agency where every department runs its own page pays repeatedly for the same compliance obligation.
  • It archives rather than governs, so it will faithfully preserve a policy violation without preventing it, and agencies still need social media policy and training.
  • Since the 2021 CivicPlus acquisition the product is part of a municipal suite, so buyers avoiding that vendor for other reasons are still buying from them.
  • The value is entirely insurance shaped, which makes it a perennial target during budget cuts right up until the first records request it would have answered.

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
