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.

Mimecast

  • No pricing is published for any product or plan, and every route ends at a quote or demo request
  • The platform is split into separately sold products for email security, awareness training, data protection and governance
  • Collaboration threat protection, DMARC analysis, incident response and email archiving are all further add ons on top of those
