Our Customers Have Spoken

Recognized as a Gartner Peer Insights™ 2025 Customers’ Choice for Email Security Platforms

We have Teams and Slack and other SaaS applications, and the fact that Abnormal can protect those as well is something we are looking at closely.

Andy Albrecht

CISO, Domino's

Whether it's QR code attacks, new malicious URL strategies, or new ways of phishing our end users, the speed with which Abnormal has detected emerging and evolving threats to keep them out of inboxes has been fantastic.

Ash Hughes

Head of Security, Berkeley Group

The proof of concept was one of the easiest ever: no impact to the infrastructure or the network, and the best and fastest results. Since we started using Abnormal, no threats are getting through.

Milos Pesic

CISO, Acelleron

Abnormal AI's pith can sometimes seem too good to be true. Thankfully, it's easy to make your assessment. We need more solutions like Abnormal to keep pace with hackers.

Marcus B.

Cybersecurity Architect and Advisor

Email threats don’t just put our company at risk. They also endanger our patients’ privacy, safety, and potentially their lives. Abnormal has helped us secure the most significant vector putting our patient data at risk.

Jeff McDonald

Senior Vice President of Technology Services, Vituity

We were impressed with the fast implementation. Within four days, Abnormal identified a BEC email that made it past M365. That could have cost a lot of money.

Blaine Carter

CIO, FranklinCovey

The way Abnormal detects vendor email compromise attacks stands out. When a malicious actor took over an ongoing vendor conversation, we could see how Abnormal assessed the change of context, the slight nuances in the way the language shifted, the addition of a file with different bank details, and the fact that the attacker interjected an email address into the CC field. I’ve never seen these things detected by a traditional SEG.

Jonny Concannon

Group Information Security Manager, Boohoo Group PLC

With Abnormal, we‘re confident that we don’t need a SEG, so we now have the time and freedom to work on other security initiatives. We believe in the product and in the value of our relationship with Abnormal.

Charles Fedorko

Director of IT Security, Sage Hospitality

Abnormal just works. It has given me countless hours back in my day.

Noah

Director of InfoSec, Real Estate Industry

Without Abnormal AI, our end users would still be receiving these malicious attacks and interacting with them, potentially costing us financial losses and reputational damage.

Gopal Padinjaruveetil

CISO, AAA/Auto Club Group

Abnormal lets me focus my time on other priorities because I know they have my back!

Director of IT, Finance

You can only go so far with signature-based detection, although that first layer of defense knocks out 90% of the threats. With Abnormal as our second layer, we can block attacks that are more targeted toward Sentara, such as social engineering invoice emails that are difficult to catch. Abnormal catches, reports, and auto-remediates them.

Chad Spiers

Director of Cybersecurity, Sentara Healthcare

Abnormal has made a huge difference in the amount of impersonation attempts reaching our users. Thanks for making the world safer!

Mark

VP of IT, Higher Education

Our systems operations and IT teams were blown away by how easy it was to connect Abnormal via API to try it out. In our head-to-head test with another solution, Abnormal detected twice the malicious emails and generated 75% fewer false positives than the other vendor.

Steve Tieland

Director, Corporate Security Operations, Pegasystems

“...Our detection rates on phishing have increased significantly and our analysts are having a much better time investigating phishing with the help of the AI tools.”

We didn't go with a SEG because we're a company of innovators and we wanted security that wasn't built on old technology. Abnormal understands today's world and the future of email security, where AI is a factor and our users' challenges keep changing.

TJ Lingenfgelter

Associate Director, Head of Information Security and Compliance, TaylorMade

Abnormal gives you a lot of insight into your threat landscape. I now know who my big targets are, who my most vulnerable users are, and I can map my users to their email risk in a way that I never could before.

Andrew

Deputy CISO, Education

This is my third time deploying Abnormal. It's one of our simplest security integrations, and it doesn't need day-to-day maintenance. As a CISO, I want more of that kind of experience. I would love it if more security products were as effective and low-maintenance as Abnormal.

Marc Bown

CISO, REA Group

“Abnormal is always willing to listen to feedback and our sales/marketing rep goes out of his way to follow-up with tickets we submit, seeing if we were helped.”

Bobby D.

Controls Analyst

We employed two SEG solutions in sequence, and that still wasn’t solving our email security problems. Abnormal frees us from inbox cleanup, so we can proactively identify and address other security threats before they become problems.

Jason Stead

CISO, Choice Hotels

“Abnormal AI is an amazing email security platform that really stands out....we've really advanced our email security posture since we are now covered from phishing, account takeovers, and BEC.”

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.

Christopher Chambers

VP of Information Security, Comfort Systems

One of the great advantages of Abnormal has been that it really runs itself; we don't run it. We're not in the Abnormal portal every day, but I can see that it's stopping the things that we need it to block.

Carl Eller

Senior Director of Information Security & Technology Management, Savannah-Chatham County Public School System

A great product with a great team that has us to bring our email security to a higher level.

Senior Systems Analyst - Construction

“Entering the future of email Security with Abnormal AI.”

Our security team has gained 40 hours back each week to focus on more strategic projects. Having that time allows the incident response team to work on things like better tuning our SIEM, better detection capabilities across the organization, and better efficacy across all of our tooling.

Jeremy Smith

CISO, Avery Dennison

Abnormal detects malicious emails, prevents those threats, and cuts down on email noise and clutter, which makes us all more efficient and helps me provide value to the company and our partners.

Brian Markham

CISO, EAB

Integrates so easily with almost no operational overhead, oh and of course it's quite effective.

Chris

IT Operations and Security Lead

Email Productivity took my mailbox from being filled with hundreds of graymail messages a day to just email that is actionable. The executive administrative assistants are in love with Email Productivity.

Bryan Willett

CISO, Lexmark

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.

Gareth Packham

Global CISO, Save the Children International

“Onboarding was quick and easy - literally integrated and up and running in less than five minutes! We also had excellent support from one of their consultants to help with the removal of our legacy SEG and transition to Exchange Online Protection.”

We were being hit by a multitude of invoice fraud attempts. Some came from genuine suppliers who had compromised mailboxes, and that business email compromise was spreading into other organisations. Nearly 30% of our security resources went to dealing with these sorts of threats, plus time spent by operations, legal, and data protection staff. With Abnormal preventing those attacks from reaching inboxes, we saved time equal to a full-time employee in a month.

Kirit Marvania

Digital Operations Director, Mace Group

We have really enjoyed adding Abnormal to our organization. It has been very helpful in keeping the malicious emails away from our end users.

Information Security Analyst

Abnormal helps protect our users from themselves. It takes some of the social engineering out of the mix for hackers to exploit! I love how it removes suspicious emails before users can interact with them.

Peter

User Support Technician, Retail

“Alot of times we are only aware of malicious or spam emails when end users report them. With the Abnormal platform, it enables automatic detect / respond which further protects our environment and end users and it also frees up our admins to be able to work on their day to day responsibilities.”

Tanner

IT-Analyst

Abnormal identifies and stops advanced email threats with such a high level of accuracy that we can focus on ministering to people, rather than spending our time recovering from email attacks. The solution is amazing and reduces our support workloads.

Matt Manire

Executive Director of Information Security, Gateway Church

Abnormal has made my C levels happy, and has made less work for me.

IT Manager - Manufacturing

“Effortlessly and dramatically improved our email security. ”

I cannot rave enough about Abnormal AI's offerings. By far one of the best O365 email security solutions out on the market today.

Brandon Corbin

Director of IT Operations, Business Wire

The threat from phishing was always in our face. Now it’s solved with Abnormal’s dependable solution.

Eric Bowerman

CISO, Elara Caring

It was click, click, boom in terms of implementation, versus the old method of changing MX records and monitoring email flows.
