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
Avast One
- Ransomware and Wi-Fi vulnerability protection only on paid plans
- Free plan VPN is limited, no data breakthrough monitoring
- Rebuilt app in May 2026 may have stability issues
