The short version

  • Only Osano has a free tier, so it costs nothing to try first.
  • Each has a real cost: Mimecast no pricing is published for any product or plan, and every route ends at a quote or demo request; Osano the published visitor ceilings are low, with the paid self-serve tier stopping around 30,000 monthly visitors, so any consumer facing site with real traffic leaves published pricing immediately and negotiates a quote with no public anchor.
  • They diverge on capability: Mimecast covers Advanced threat detection, Osano covers Consent banner.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Mimecast

  • Email security filtering against phishing and targeted attacksnot Osano
  • Email archiving, continuity and compliance for organisationsnot Osano

Osano

  • A mid market company selling into the EU and California that needs one banner honouring different consent rules by visitor regionnot Mimecast
  • A privacy counsel who wants a vendor that will contractually stand behind its consent product rather than disclaim all liabilitynot Mimecast
  • A marketing team that needs Google Consent Mode signals wired correctly so analytics and ads degrade rather than break when consent is refusednot Mimecast
  • A company with a handful of brand domains wanting one consent record and one scanning schedule across all of themnot Mimecast

Where each one falls short

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

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

Osano

  • The published visitor ceilings are low, with the paid self-serve tier stopping around 30,000 monthly visitors, so any consumer facing site with real traffic leaves published pricing immediately and negotiates a quote with no public anchor.
  • The no fines guarantee is bounded and conditional on configuring the product as instructed, so it is a marketing differentiator with an indemnity cap rather than the insurance policy the name suggests, and the limits should be read before it influences a decision.
  • Everything beyond consent, including subject rights automation, data mapping and vendor monitoring, is enterprise quoted, so the transparent pricing that attracts buyers covers only the cheapest part of the platform.
  • Tag blocking depends on tags being loaded through the mechanisms Osano can intercept, and marketing teams that inject scripts directly into templates or through server side tagging routinely leak trackers past the banner without anyone noticing.
  • It is a privacy platform rather than a security compliance one, so organisations that also need SOC 2 or ISO 27001 evidence collection run it alongside a separate tool and duplicate parts of the vendor and asset inventory.
