“Overall, our experience with Abnormal AI has been very positive. The platform has delivered immediate value with minimal operational overhead and has integrated cleanly into our existing email environment. From both a security and user-awareness perspective, it has strengthened our posture against email threats while remaining manageable for a small IT/security team. Abnormal AI has proven effective at reducing email risk while requiring little day-to-day administration.”

“From RFP to selection, implementation to daily use, Abnormal has been a pleasure to work with. They provided assistance in creating a plan to move away from the SEG we were using and helped us to fully utilise all of the settings to get the best value from their tool.”

“Abnormal has been a great partner to my company. The amount of malicious emails my employees used to receive is staggering. Abnormal helped reduce our exposure by more than 99.95%. It was an eye opener when we activated it and saw the first report.”
