KnowBe4 Defend is an AI-powered inbound email threat protection solution that protects organizations from advanced phishing and email threats. The product uses self-learning AI, real-time threat detection, and user education to complement existing email security infrastructure by analyzing user behavior, message content, and intent. The solution employs AI-enabled phishing detection using self-learning techniques, behavioral intelligence and natural language processing. It features an adaptive security architecture that adjusts detection based on calculations from all emails processed by the system. The product provides holistic detection that analyzes all aspects of an email including headers, links, and attachments. Behavioral AI and language understanding capabilities detect phishing, impersonation, and social engineering using message tone, structure, and context. The solution displays dynamic, color-coded contextual warning banners that alert users based on real risk and provide real-time advice. Link rewriting functionality prevents time-based attacks by checking links at the time of click. QR code detection warns users of quishing attempts embedded in QR codes. Automated response and remediation capabilities help security teams respond to potential incidents. Defend enhances Microsoft 365 native security to catch threats that Secure Email Gateways miss. The product operates after SEGs and Microsoft 365 have performed analysis at the perimeter, and when suspicious emails are identified, it automatically leverages Microsoft's quarantine functionality for immediate containment. The solution identifies business email compromise, ransomware, and spoofing attempts that slip past legacy tools while providing tailored security based on individual user risk profiles.
