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.

What do you like best about the product?
I'm a Cyber Security Engineer at a medium size financial services company. Our motive for using Abnormal Security is to defend our Microsoft 365 tenant against sophisticated phishing and Business Email Compromise (BEC) attacks, as well as vendor impersonation attacks, that our normal Secure Email Gateway (SEG) could not defend against. Our SOC team also uses its automated remediation capabilities to deal with the huge volume of emails that are reported to them with suspicious content.The best thing about Abnormal is the deployment itself is so simple. Since it integrates directly using Microsoft 365 APIs rather than needing intricate MX record modifications, it was up and running in our environment in just a matter of moments. The AI engine's ability to grasp the nuances of communication and To ensure the proper setting for what's considered the norm in employee performance is extremely precise. Commonly discovers highly advanced attacks and forgery of vendor invoices with no visible malicious links or attachments. Prior to Abnormal, at least half of a security analyst's day would be spent manually examining reported email or ramping through their inboxes, one by one. With the platform's auto-remediation, though, nearly all of that is done in the background, and that's a giant timesaver for our small team. It is indeed a high dollar solution to use Abnormal Security versus traditional email security, but for our team, the ROI has been 100% worth it. The per-mailbox pricing model seemed like a bit of an "up front investment" for a medium size user base. This combination of user-provided policy and the overwhelming number of engineering hours our SOC analysts put in taking care of user-reported phishing tickets weekly makes the platform self-funding not just in recovered productivity, but in recovered time. Most important of all, denying one costly vendor scam or bogus wire transfer message eradicates the entire yearly position. Automation and risk reduction are worth a lot for asecurity team faced with heavy workload and members who can't keep up with threats in their inbox all day.
What do you dislike about the product?
Abnormal works through the API (asynchronously, not within the mail flow itself as a traditional gateway would be) so scanning processes are not synchronous. This implies a malicious e-mail will appear in a user's inbox for a few seconds in between the AI system analyzing it and retriving it. There's a very fine margin for error if someone is focused on their inbox and presses the keys really rapidly. Also, there are instances when the system is a bit too strong in money related emails; it may mistake for example a genuine invoice or a message from a collaborator for ‘graymail' and perhaps even ‘potential threat'. Succumbing to these false positives takes some time as it isn't always readily possible to just whitelist a trusted domain without a bit of a hoop-jumping exercise.
What problems is the product solving and how is that benefiting you?
The danger of account takeover and targeted VIP spoofing was huge as our CEO would be involved in emergencies calls for wire transfers under fake names. Our previous gateway only protected on a threat signature basis and had no protection against text only attacks. But in Abnormal they realized that our executives really do write and communicate. It recently thwarted a dishonest vendor who asked our finance department to wire funds to another account for a bill worth hundreds of thousands of dollars. So, by automating the triage on our abuse mailbox and preventing these zero day social engineering attacks, it has cut our organisational risk even down to the next level and allowed us to direct our security team's efforts towards proactive threat hunting as opposed to copious amounts of email management.

Fast API-based email security that drastically cuts down manual alert triage
Reviewed on Aug 20, 2026
Review provided by G2
What do you like best about the product?
As a SOC analyst, user-initiated phishing reports and account takeover detection take a lot of time to process, and I spend the whole shift looking at them. In my opinion, the most attractive feature of Abnormal AI is the speed of detection of Microsoft 365 account compromise compared to traditional secure email gateways. The software was installed via API for Microsoft 365 or Google Workspace, so it did not require much time and did not affect the mail delivery in any way. The dashboard named Threat Log allows me to get more information about the suspicious email activity, including details of the detected attack vectors, and the specific vendors involved in the incident. The automation of response to detected threats by removing the suspicious email from all the user’s inboxes or downing the compromised account significantly reduces the workload compared to using only PowerShell to remove the emails. Additionally, I find the ability to track all the user-initiated phishing reports and automatically reply to them helpful, as it saves a lot of time on ticketing and closing the incidents that do not require any further action.
What do you dislike about the product?
While I find the detection engine to be very accurate, the user interface may cause some frustration when dealing with multi-step queries. For example, when I am trying to sift through a ton of information in the threat logs, my selected filters do not carry over when I open up an alert and have to navigate back. This causes me to have to re-filter what I am looking at and slows down the overall process of incident response.
What problems is the product solving and how is that benefiting you?
It is mainly eliminating false positives through automated triage instead of spending hours on end checking them manually, which we had to do before without any success. It also helps by removing credential theft attempts and business email compromise by stopping targeted spear-phishing before it reaches the inbox, so our SOC team can concentrate on proactive threat hunting and not just responding to false positives.
