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.

Abnormal AI is an email security tool that is continuously expanding its offerings and making product improvements. Our experience with the tool has varied, there have been times where we lost all confidence in the tool and worked with our AM team to voice our concerns and have them addressed. Overall, it does the job - most of the time.

It Manager

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.
