constantly evolve their techniques and tactics to outwit and
undermine traditional approaches to email security. That’s what

consistently been recognized as one of the top cybersecurity
startups, and our behavioral AI system has earned numerous industry
accolades. We’ve built our reputation and brand through our
industry-leading email security solution, which now protects more
than 20% of the Fortune 500. As Abnormal expands its ambitions
beyond email into the broader Identity Security landscape—while
also maintaining and scaling our email security products—a
