"Effortless Email Security with Abnormal AI"
5/5
What do you like best about Abnormal AI?

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 Abnormal AI?

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.

"Effortless Email Filtering, High Effectiveness"
5/5
What do you like best about Abnormal AI?

I love how effective Abnormal AI is in filtering emails, accurately catching phishing attempts and filtering spam, which makes my email experience safer and more efficient. Additionally, I appreciate the ease of use of the platform, which simplifies my workflow and makes it accessible without a steep learning curve. Abnormal AI's cost-effectiveness and high level of performance were key factors in my decision to switch from Cisco. The initial setup was very easy, allowing me to integrate the platform seamlessly into my existing systems. Consequently, I am extremely satisfied with Abnormal AI, so much so that I would rate my willingness to recommend it to a friend or colleague a ten out of ten.

"Reliable Behavioral AI for Email Security That Actually Delivers and Much More!"
5/5
What do you like best about Abnormal AI?

Abnormal AI stands out for its advanced threat detection capabilities, particularly in identifying socially engineered attacks like BEC's and account takeovers. After dumping the traditional email security gateways for them e-mail security was all of a sudden interesting again because I actually had time to be proactive and not reactive. Review collected by and hosted on G2.com.

What do you dislike about Abnormal AI?

There truly isn't much to dislike. No product is perfect and all of them require proper attention and time. This one saves you both, but are still required. In this business there's unfortunately no such thing as "set and forget" Review collected by and hosted on G2.com.

"Incredibly effective at stopping advanced email threats with solid accuracy and no tuning required."
5/5
What do you like best about Abnormal AI?

The interface is clean and easy to use, and the threat insights are clear and actionable. What really stood out to me is how little configuration was needed—it worked right out of the box and integrated smoothly with Microsoft 365. Since we started using Abnormal AI, the number of email threats reaching end users has dropped to nearly zero, which has made a significant difference in improving our organization security and workload. I'm really impressed with the speed and detection accuracy. Review collected by and hosted on G2.com.

What do you dislike about Abnormal AI?

Overall, it's a very solid platform, but there are a few things that could be improved. On very few occasions, legitimate emails get flagged, and since end users aren't notified or don't understand why the email was held, it can cause confusion. Better tools for reviewing and releasing these messages quickly would improve the experience. Also, as a post-delivery solution, Abnormal can’t always act fast enough on certain threats like malicious calendar invites. For example, Outlook may auto-process an invite and add it to the calendar before Abnormal deletes the email, which creates a potential risk. Addressing this requires changing default Outlook settings, which isn’t ideal. Review collected by and hosted on G2.com.

"Abnormally Good"
4.5/5
What do you like best about Abnormal AI?

We were early adopters of Abnormal as the API integration is the way forward, and getting off from Secure Email Gateway framework. API integration was done in minutes, and the Dashboard is easy to comprehend. We compared Abnormal with other platforms, and they stood out for ease of usage, ability to identify and differentiate from genuine and malicious email and high rate of efficacy. The greatest thing about Abnormal is once you set it up, you don't have to make changes. I look at the Dashboard infrequently, and it keeps doing its job. Machine Learning learns from user submissions and improves over time. Abnormal Customer Support is also very good and CSM helps to improve continuously. Review collected by and hosted on G2.com.

What do you dislike about Abnormal AI?

Inability to customize for deep scanning in the first iteration Review collected by and hosted on G2.com.
