What is a phishing simulation vendor (e.g., KnowBe4)?

Phishing simulation vendors provide platforms for security awareness training. Leading providers include: **KnowBe4** (largest market share), **Proofpoint** Security Awareness, **Cofense** (formerly **PhishMe**), and **Barracuda** PhishLine.

Platform capabilities: simulated **phishing** campaigns, training content libraries, reporting dashboards, and integration with other security tools. Managed services handle program operation for organizations lacking internal capacity.

Selection criteria: campaign realism, training content quality, reporting granularity, ease of administration, and pricing model. Most vendors offer similar core capabilities; differences are in execution and support.
