AI Guardian is artificial intelligence cloud security platform that protects your email against targeted attacks such as impersonation, payroll fraud, invoice fraud, and zero-day credential phishing. Powered by natural language understanding (NLU), the AI Threat Defense detection engine analyzes thousands of signals across identity, behavior, language, and global threat data to catch attacks missed by legacy solutions.
