KnowBe4 PhishER/PhishER Plus pricing is best suited for mid-market organizations with 51-1,000 employees, who represent the majority of G2 reviewers and consistently report strong value. Industries including manufacturing, financial services, education, and government administration appear frequently among satisfied G2 users. The volume-tiered pricing of KnowBe4 PhishER/PhishER Plus makes it increasingly attractive for organizations with 1,000 or more seats, where per-seat costs drop significantly. Small businesses can adopt it at the entry tier, though some G2 reviewers flag cost as a concern at smaller scales. Enterprise organizations benefit most from custom pricing and advanced automation capabilities.
