Featured Testimonials

  • “If you’re using a traditional SEG, tweaking dials, checking buckets, and manually remediating things, Abnormal provides modern email security built to work with today’s cloud platforms on a budget.”

    Peter MuellerSystems Programmer

  • “We were looking to move to Mimecast, which was pretty cool. Then Abnormal came along and blew it out of the water with better functionality and a smarter way of doing things.”

    Jim RobinsonChief Information Officer

  • “Abnormal’s behavioral AI-based solution detects more attacks than our former SEG, and it works seamlessly so I can sleep at night. Abnormal was the easiest solution for us to implement, and it keeps us incredibly secure.”
