Featured Testimonials

  • “Abnormal has delivered on their promises to save us time and better protect our email ecosystem. It’s so easy to implement, and we never want to turn it off.”

  • “We knew that a solution using AI and machine learning would be a better option than a static solution using compromise indicators like hashes and signatures. The more I looked into what Abnormal was doing in terms of AI and ML, the more I became a big fan of their approach versus what I was seeing from other vendors.”

  • "Before Abnormal, when a malicious phishing email got in, I’d search, find it, and manually purge it, Eliminating one phishing email from the environment could take anywhere from 30 minutes to an hour, and we were dealing with it multiple times each week.”
