  • They diverge on capability: KnowBe4 covers Security awareness training, Sophos Intercept X covers Deep learning AI.
  • Prices and features above were last checked on 30 August 2026.

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

Sophos Intercept X

  • Sophos publishes no price for endpoint protection: the product page names editions but gives no per user rate, no minimum seat count and no contract length, and routes buyers to a sales enquiry
  • Extended detection and response requires the Advanced with XDR edition rather than the base endpoint product
  • 24x7 monitored detection and response is sold as the separate Sophos MDR service on top of the endpoint licence
  • The Intercept X name has been retired in favour of Sophos Endpoint, so older documentation refers to a brand the vendor no longer uses
