Where each one falls short

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

HashiCorp Vault

  • Policies are written in HCL with no graphical user interface for policy management or editing
  • Unsealing requires managing multiple key shares and coordinating a quorum of operators
  • Community Edition lacks enterprise features like namespaces and disaster recovery replication
  • Requires additional monitoring solutions for alerting and observability

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
