Featured Testimonials

  • “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.”

  • "If cybercrime was a country whose wealth was measured through GDP, it would be the third richest country in the world. It’s now a ten-trillion dollar business that has overtaken the global drug trade. Meanwhile, organizations are investing just $150mn per year into cyber innovation. We as an industry need to do something to reduce this fast-increasing gap.”

  • “We work in difficult environments where the cybersecurity risks are high. The children and families we work with, our staff, and our partners need to know their data is safe with us. Abnormal plays a huge part in our ability to deliver on that mission.”
