    Overview

    Email remains the #1 cause of breaches and #1 source of cybercrime losses to enterprises (Source: FBI Internet Crime Report). As attackers leverage generative AI and sophisticated social engineering, traditional security approaches that rely on threat intelligence and static rules are no longer sufficient. Organizations need a modern solution that deeply understands human behavior to protect against these evolving threats.

    Abnormal Security delivers unprecedented protection through its AI-native platform for human behavior security. By leveraging a unique API-based architecture, Abnormal ingests 10x more behavioral signals than legacy solutions, enabling deep understanding of every employee and vendors behavior patterns. This foundation powers precise detection of anomalies and suspicious activities, stopping advanced attacks like business email compromise, supply chain fraud, account takeovers, lateral phishing, and AI-generated impersonation attempts before they can cause damage. For example, Abnormal detected and stopped a $13.5M payment fraud attempt where an attacker compromised an email account, created a look-alike domain, and sent a fraudulent invoice. Abnormals AI flagged anomalies such as the newly registered domain, suspicious email headers, and unusual language patterns, preventing the attack before any harm occurred.

    Beyond superior detection, Abnormal transforms security operations through AI automation. The platforms AI Security Mailbox eliminates manual triage and investigation of reported emails, while automated remediation capabilities instantly remove threats across all mailboxes. This automation, combined with features like AI-generated security awareness training and intelligent graymail management, reduces SOC workload by 95% while improving employee productivity.

    Deployed in 60 seconds via API, Abnormal integrates seamlessly with Microsoft 365 and Google Workspace without the need for professional services or ongoing admin overhead.

    Key Benefits -Integrates in 60 seconds, deploys without professional services, and operates autonomously with no admin overhead. -Leverages behavioral AI to detect and stop novel email attacks while fully automating SOC operations, including phishing mailbox management, security training, and attack remediation. -Expands protection beyond email by using human behavioral AI to detect and remediate account takeovers (ATO/UATO), securing cloud platforms and preventing unauthorized access.

    Abnormal is recognized for its customer-first approach and commitment to innovation. Named a "Leader" in the Gartner Magic Quadrant for Email Security Platforms with the "Most Completeness of Vision," Abnormal also boasts a 99% customer "Would Recommend" rating, reflecting its industry leadership and dedication to excellence.

    Highlights

    • Comprehensive Protection with Behavioral AI - Abnormal's behavioral AI analyzes tens of thousands of organization-specific signals to detect advanced email threats.

    Effortless Email Security with Abnormal AI

    Reviewed on Nov 17, 2025
    Review provided by G2
    What do you like best about the product?
    I am genuinely impressed by how accurately Abnormal AI detects threats, ensuring that it doesn't mistakenly block legitimate emails. This precision means we don't waste any time managing email queues or dealing with false positives that require manual release, as we often did with traditional email security gateways like Mimecast. Managing email risk is now much easier, and the switch from Mimecast, which failed to reliably block malicious emails, was long overdue. The setup process for Abnormal AI was effortlessly easy, adding to the smooth transition. The effectiveness of Abnormal AI in protecting our emails and Microsoft Teams messages, along with its ability to detect unauthorized use of our accounts, is exceptional. I feel confident in our security posture management and greymail filtering with Abnormal AI's help, significantly reducing the risk associated with our M365 platform's configuration.
    What do you dislike about the product?
    I find the user interface of Abnormal AI could be more responsive. Improvements in cloud resilience are needed, especially after the recent outage. Additionally, further integration into M365 email for a single view of all message tracking would be beneficial, although I acknowledge this may not be easy to implement.
    What problems is the product solving and how is that benefiting you?
    I use Abnormal AI to enhance email and message security, effectively blocking malicious emails and unauthorized account use. It reduces false positives and eliminates the need for managing email queues, providing accurate threat detection without errors.

    AI has helped classify threat types more accurately but product ownership can improve

    Reviewed on Oct 28, 2025
    Review provided by PeerSpot

    What is our primary use case?

    The main use case for Abnormal Security is as a spam filter and for mail hygiene. This use case is for the finance industry.

    What is most valuable?

    Abnormal Security's AI capabilities are what we like most, as they can categorize and classify the emails, and based on the context of the email, understand if it's a graymail, a bulk mail, or a phish. Some valuable insights and analytics from the dashboard include productivity-level and threat-level metrics, such as time spans and emails recalled.

    What needs improvement?

    Ease of use is important, and Abnormal Security's responsiveness and ability to deliver solutions when issues arise are crucial. However, there is always room for improvement, as achieving a perfect 10 means there is no more room for enhancement. For Abnormal Security, it's about leveraging AI even more, which they are already working on in their roadmap.

    For how long have I used the solution?

    We have been using this product for two years.

    How are customer service and support?

    I would rate their overall support, including account representatives, sales, and technical support, as an eight.

    How would you rate customer service and support?

    Positive

    How was the initial setup?

    The integration process with Abnormal Security into our existing infrastructure was pretty easy.

    What other advice do I have?

    We do have experience with Abnormal Security, and we are currently using it. For Abnormal Security as a product, I would say probably somewhere around a seven, as there are some other areas where they can improve to achieve a higher rating. The review rating for Abnormal Security is an 8.

    Blown away by how effective this platform is a stopping phishing emails.

    Review provided by G2
    What do you like best about the product?
    It catches everything, we had this system in a live state for over a month now and I haven't seen a single phishing email slip through.
    What do you dislike about the product?
    It's a premium product, with a fairly high price tag.
    What problems is the product solving and how is that benefiting you?
    Our traditional Secure Email Gateway was letting through so many malicious phishing emails, I trialled Abnormal for 3 months and it blocks everything. I'm aware that at some point something will slip the net but that's why we have Cyber Awareness Training, 24/7 monitoring, and Antivirus. I don't want to rely on this platform 100% but it's almost unbelievable how well it works, I will recommend this platform to anyone.

    Fantastic Product, Extremely effective.

    Reviewed on Oct 03, 2025
    Review provided by G2
    What do you like best about the product?
    I appreciate the accuracy and effectiveness of the solution. After it was set up and implemented, my team has needed to spend very little time managing or administering it.
    What do you dislike about the product?
    Honestly, there isn't much that I dislike. However, I do feel that some of the reporting and filtering settings could be improved. For example, when searching for something, the selected filters often don't persist between menus, which means I have to recreate the filter and search again. Other than that, the product is expensive, but you are paying for something that is quite advanced and arguably among the best in its field.
    What problems is the product solving and how is that benefiting you?
    Abnormal AI is serving as mail protection from phishing attacks, filtering out spam messages and proactively moving promotional material to a dedicated folder. On top of that we're also investigating their posture management solution for Entra ID.
