Abnormal AI Reviews, Ratings & Features 2026 | Gartner Peer Insights

Gartner defines an email security solution as a product that secures email infrastructure. Its primary purpose is to protect against malicious messages (phishing, social engineering, malware) or unsolicited messages (spam, marketing). Other functions include email data protection; domain-based message authentication, reporting and conformance (DMARC); investigation; and remediation through a dedicated console. Email security solutions may also support nonemail collaboration tools, such as those for document management and instant messaging. Email security tools protect an organization’s email from spam, phishing, malware attacks, account takeover and data loss. They may provide capabilities for data loss prevention, encryption, domain authentication and security education, as well as advanced protections against business email compromise. Email security platforms give cybersecurity teams visibility into email-related security incidents, support investigation and automated remediation, and enable management of both inbound and outbound email delivery. Email security solutions often integrate with other network, identity and endpoint security controls, and may also support collaboration tools and email relay capabilities.

Initial teething issues with training the model that dragged on despite the best efforts of the vendor. We found it had fundamental flaws and they couldn't give us a path to rectify these issues. Experienced AI model issues that affected multiple customers that had real business impact.

We started looking into Abnormal to replace a more traditional email gateway solution that we had in place. We were spending a lot of time constantly maintaining block lists and sorting through false positives. We were spending a lot of time trying to tweak things to protect against incoming threats, only to have attackers switch tactics and eventually get through. It was a constant cat and mouse game, and we felt we were always behind. 

When we first deployed Abnormal and ran through a POC, we layered it on top of our existing solution. It was both impressive but also alarming as we quickly discovered the volume and extent of just what was coming through our traditional solution. 

Abnormal from the time we started the POC to full implementation Abnormal has just worked. I was amazed at just how easy it was to setup and configure as well as just how effective it's been. Abnormal has been truly transformative not only for my team, but our business as a whole.
