The short version

  • Only Proton Mail has a free tier, so it costs nothing to try first.
  • Each has a real cost: Delinea the Thycotic and Centrify lineages are integrated unevenly, so buying the full portfolio means running consoles and agents that do not share one administrative model as cleanly as the marketing suggests.; Proton Mail paid plan pricing not displayed on vendor site

Where each one falls short

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

Delinea

  • The Thycotic and Centrify lineages are integrated unevenly, so buying the full portfolio means running consoles and agents that do not share one administrative model as cleanly as the marketing suggests.
  • Modules are licensed separately by different units, per privileged user for the vault and per endpoint for privilege management, which makes total cost hard to model and easy to underestimate at scale.
  • Delinea does not publish rates, so buyers benchmark against third party and public sector listings; expect list prices to be negotiable by a wide margin, which means the first quote is not the price.
  • Thoma Bravo ownership since 2021 has coincided with firmer renewal pricing, and buyers with a single-vendor PAM estate have little leverage once credentials are inside the vault.
  • Migrating out of a privileged access vault is a genuinely hard project because every automated process that fetches a secret has to be repointed, so the switching cost is real and the vendor knows it.

Proton Mail

  • Paid plan pricing not displayed on vendor site
  • Free tier limited to 1 GB storage
  • Free tier limited to single email address
