What Reviewers Say on Gartner Peer Insights™

“Abnormal has been a strong addition to our email security stack. It reliably identifies and remediates advanced phishing and BEC style attacks, and the AI security mailbox has noticeably reduced manual workload for our security team.”

Anonymous Reviewer

Gartner Peer Insights™

“Overall, our experience with Abnormal AI has been very positive. The platform has delivered immediate value with minimal operational overhead and has integrated cleanly into our existing email environment. From both a security and user-awareness perspective, it has strengthened our posture against email threats while remaining manageable for a small IT/security team. Abnormal AI has proven effective at reducing email risk while requiring little day-to-day administration.”

“From RFP to selection, implementation to daily use, Abnormal has been a pleasure to work with. They provided assistance in creating a plan to move away from the SEG we were using and helped us to fully utilise all of the settings to get the best value from their tool.”

Anonymous Reviewer

“Abnormal has been a great partner to my company. The amount of malicious emails my employees used to receive is staggering. Abnormal helped reduce our exposure by more than 99.95%. It was an eye opener when we activated it and saw the first report.”

What Customers Say About Abnormal

Real feedback from security leaders who switched to Abnormal.

Showing 24 of 339

“Abnormal’s automation gives our analysts time back to work on other projects, and the fact that it’s API-based gives us flexibility to tie in other applications and their data.”

John Roeser

Senior Manager, Information Security, Domino's

“Before Abnormal, when we analyzed a message and determined that it was malicious, we had to login to our other security tools to put blocks in place. Then we had to search for and remediate each instance of the message in our email system. It was very time-consuming, but with Abnormal, there’s no longer a need for our security team to manually manage those emails.”

Jeremy Smith

CISO, Avery Dennison

“Human behavior is a big issue in cybersecurity. When you're dealing with organizations that include thousands of people, you need a solution that takes that into account and protects less tech-savvy users from themselves. Abnormal’s human behavior AI accomplishes this.”

Noah Davis

VP and Global CISO, Ingersoll Rand

“Abnormal looks modern, and it was easy to run the POV and move into production. We quickly realized that we could reduce our email security maintenance and troubleshooting workload with this platform.”

Jason Thorn

Director of Security Operations and Incident Response, Rate

“A SEG isn't viable in today's world because it can't catch new email attack methods. The priority for me was finding a solution that could remediate all these email threats and accelerate time to value,”

John Barrow

CISO, JB Poindexter & Co

“Before Abnormal, it could take an analyst half a day to deal with a phishing email. Now we've had over a 98% reduction in attack emails getting through. Our cybersecurity analysts like the fact that Abnormal works in the background without manual review, but the dashboard makes it very easy to still get the information they need.”

Gareth Packham

Global CISO, Save the Children International

“It's great to have a single pane of glass with both of our email platforms. We can see everything in one place, and Abnormal AI performs extremely well for our M365 and Google tenancies, despite the fact that the user behaviours and threats are markedly different between them.”

Joanna Dalton

Head of Cyber Defence, REA Group

“Whatever the next threat is, we trust Abnormal to get in front of it.”

Nathan Kelly

Sr. Engineer, Information Security and Compliance, TaylorMade

“Abnormal's human behaviour AI and automation have helped us modernise our security and prepare for the future. Using AI to spot risky email behaviour by knowing what 'good' looks like is powerful, and it naturally extends into phishing simulations and security awareness.”

Phil Lea

Head of Privacy and Cyber Security, Landmark Group

“Increasingly, threat actors will use large language models to increase attack sophistication through things like customized real-time phishing emails based on something like a target’s LinkedIn profile. The only way to combat that social engineering is with a product like Abnormal that uses AI to understand email content and context.”

Jeff Deakins

Director, Information Security and Infrastructure, Marmon Holdings, Inc.

“It’s human nature to respond to messages quickly, and attackers use that to get into your mind. Having Abnormal’s behavioral AI looking for those events is critically important to protect our users and customers.”

Bryan S. Willett

CISO, Lexmark

“Today's threat landscape is very dynamic, changing. You'd stay ahead of the game by leaning in on technology to help with the fight. Modern technologies like artificial intelligence and machine learning can really understand the dynamic of what's normal and what's not.”

Ryan Fritts

CISO, ADT

“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 USA

“We want a partner that's going to constantly push the envelope and continue to innovate because the bad guys are doing the same thing… Abnormal's definitely pushing the envelope. We like to see it. And more importantly, when we give feedback, we feel like it's being heard.”

Lorenso Trevino

CISO, Pima Community College

“Email is the easiest route for threat actors to get into an organisation, and it’s easy if you can spoof an email or socially engineer an individual’s behaviour. Abnormal AI solves for that and gets smarter every day.”

Santanu Lodh

CISO, OFX

“With the CrowdStrike-Abnormal integration, we have higher fidelity information going back and forth, and we’re getting better information right at the edge of our network so we have enriched data that's going to our SIEM. As a result, I'm getting higher fidelity alerts and the ability to automate more of the process before I alert our analysts.”

Brian Miller

CISO, Healthfirst

“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.”

Chad Spiers

Director of Cybersecurity, Sentara Healthcare

“From day one, the Abnormal team was interested in building a relationship and understanding how they could make our experience better, including offering to make feature requests to meet our needs. The platform’s performance and ease of use, and the Abnormal team’s responsiveness set Abnormal apart from other email security providers.”

Ash Hughes

Head of Security, Berkeley Group

“We were nearing the end of our existing SEG contract, and had dealt with a couple of incidents that were not only causing our team headaches but also costing us time and resources. At Sage, we seek out partners who operate with a similarly nimble and entrepreneurial mindset as us. Abnormal has proven to fit that model, and has already been a great partner for us in the time we've worked together.”

Matt Schwartz

CTO, Sage Hospitality Group

“Abnormal has stopped several attacks from supposed vendors. One involved a trusted supplier whose email had been compromised. The personalised attack requested a deposit on an active project to a new account. With Abnormal, we're not just protecting WaterAid, we're also protecting our suppliers, and that increases trust.”

Mark Sedman

Head of Global Cyber Security, WaterAid

“AI like Abnormal's is the only feasible, reasonable way to defend against advanced threats, especially as more attackers adopt AI for malicious purposes. As the complexity of phishing increases, using AI makes sense, and Abnormal based their solution on AI from the start.”

Bruno Bedin

CISO, Bühler Group

“We didn't want a solution that would increase the amount of complexity and create a new burden for the security operations team. We also wanted a platform with really high efficacy and minimal false positives. Abnormal ticked those boxes for us and allowed us to bring an effective new layer into our security environment without overcomplicating our business.”

Mark Overton

Head of Information Security, Softcat

“When we learned about Abnormal, we were surprised that it fit exactly how we needed it to. We didn’t need to replace our security stack, and we could set it up in five minutes,”

Jeff McDonald

Senior Vice President of Technology Services, Vituity

“Abnormal gives us a robust suite of phishing examples that we can use to train our employees, and it’s not just about training them for their corporate world, but also for their home lives.”

Jason Stead

CISO, Choice Hotels
