Where each one falls short

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

KnowBe4

  • Published prices assume a three year term, so the quoted per seat rate depends on a long commitment
  • Pricing is banded by seat count, and the lowest band of 25 to 50 seats pays the highest rate
  • Accounts above 1,000 seats have no published price and require a custom quote
  • Third party integrations, Compliance Plus and PhishER Plus are all separately priced per seat add ons
  • The Foundation tier carries 200 training modules against more than 1,000 on Advanced, so content volume is the main gate

Tuta

  • Individual plan pricing only shown in EUR; no USD conversion provided on site
  • Family plan pricing separate (EUR 3 or EUR 8 per additional user) not included in main pricing
  • Shared mailboxes require additional EUR 3-8 monthly charges
