Featured Testimonials

  • “Abnormal made it easy to see what our SEG was missing. We set up the POV in a few minutes and then there were a lot of ‘Aha!’ moments about what the SEG wasn’t finding. It was clear right away that Abnormal could deliver better protection and a quick time to value.”

  • “Investigation and remediation were very time-consuming for our team. Abnormal automated our manual processes and provided more efficacy at the same time. That allows us to focus our security resources in other places.”

  • "During our peak threat season, we experienced a 36% reduction in response efforts to email threats that make it past our SEGs. Because of Abnormal, our busiest months this year have required less response work than our quietest months last year.”
