What is Abnormal Security?

Abnormal Security is an AI-powered email security platform designed to detect and block advanced phishing attacks that traditional email filters miss. It analyses email behaviour patterns, sender characteristics, and content to identify threats in real time. The platform uses machine learning to understand what normal communication looks like for your organisation, then flags suspicious deviations. It's built for businesses of all sizes that want to protect their staff from sophisticated phishing campaigns, credential theft, and business email compromise attempts.
