Email Security
High-efficacy, AI-powered protection that catches what others miss.
Effortlessly block and isolate phishing threats, including email-borne malware, business email compromise (BEC), and multi-channel (link-based) attacks — before they reach your users
BENEFITS OF EMAIL SECURITY
99.99% Phishing detection accuracy
Block sophisticated phishing threats, including BEC, multi-channel (such as email, messaging apps, and collaboration tools), and evasive link-based attacks, with industry-leading accuracy powered by AI.
Protection that goes beyond email
Protect against targeted phishing attacks that use a combination of email and other collaboration apps (such as social media, Slack, Teams, SMS, etc.) to exploit users and gain unauthorized access.
Flexible deployment options
Deploy inline, via API, or both—combining pre-delivery email processing, real-time link analysis, and post-delivery retractions for complete protection.
AI-powered detection
We combine AI, global threat intelligence, and expert-driven rules to detect sophisticated phishing threats like BEC. Each email is analyzed across hundreds of attributes—from sender reputation and message sentiment to conversation context. Our patented email detection fingerprint (EDF) uncovers hidden patterns across phishing campaigns. A unified detection engine merges ML scores with real-time threat signals to stop malicious emails instantly. Continuous rescans and feedback loops, supported by our AI audit models and ex-NSA and CIA security analysts, drive constant improvements in accuracy.
