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

Experience high detection and user-friendly policies with reliable email security implementation
The system is not user-friendly because you have to create policies that are mapped in a dictionary. As an IT engineer, I understand how it works, but explaining it to another IT person can be difficult. Having more user-friendly dashboards would improve the work experience. In Mimecast Email Security, checking policies in the dictionary or gateway is very complicated, and not everyone understands this process. If you examine the Check Point portal, it's user-friendly with easily accessible tabs that anyone can explore. With Mimecast Email Security, making changes might impact existing mailboxes. The portal is complicated compared to Check Point's user-friendly interface.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It does some really cool stuff that other tools aren't doing. We found it to be really effective, and the AI/ML functionality is really what differentiates them."
"The features that appeal to me most are the combination of auto-remediation and Detection 360."
"I like Abnormal's threat protection with auto-remediation, but I also love its abuse mailbox feature, which automatically responds to the end user. That feature has a super-valuable security component and helps improve the user experience."
"Initial auto-remediation allows us to auto-remediate before the email lands in the end user's inbox for a split second."
"I have never encountered any stability issues with Abnormal."
"What I like about Abnormal Security is that it notifies me if any of my partners or suppliers are experiencing a security breach by analyzing their database and identifying potential cyber threats."
"I would recommend Abnormal Security."
"Ease of use is undoubtedly one of the most valuable features of Abnormal Security."
"It has all the features required for distribution, such as the ability to mail."
"The reviewer gave Mimecast Email Security a rating of 10 out of 10."
"It does a good job for us, and its admin console is easy to use."
"Mimecast has been in the market for a long time; it's a good tool if you want to simplify your operations and a good tool for removing on-prem appliances that otherwise you would need to do with the protection that Mimecast provides."
"Its administration console is very easy to use. The administration console is absolutely important because you interact with the platform through it."
"The solution offers good technical support."
"It's good, it keeps the spam out, and it does a really good job at not allowing threats through."
"I have always found Mimecast to be very responsive; for example, if we see something come through, they address it and it helps to sort out the issues."
 

Cons

"When we're working on something as engineers, and we find an idea or a method of doing something that would be greatly improved by doing it another way, there should be an ability for me to click the ideas button, type in an idea that I have, and submit it to a product review team or developers to have them think through the process a little bit more."
"One feature I'd love to see is outbound scanning."
"There could be more selectable options and more granular selections available."
"I would like to have the ability to customize the auto-remediation feature."
"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 pricing for academic institutions and student mailboxes is challenging."
"There could be room for improvement in enhancing integration with other cybersecurity tools."
"I, as such, do not have anything that I do not like or would like to add, but you could argue that because they are doing it API-based, there is a chance that something could slip through temporarily before they are able to pull it out. In theory, it could happen just because of the nature of the system. They are not in line with the delivery of the mail. They are kind of asynchronous, which is a pro as well as a con. If it is synchronous, then I know it would always stop them, but because it is asynchronous, things could get through temporarily or because of some system issues on the Microsoft side or their side. It is the nature of the beast, but it is a little bit of a con."
"I'd like to have better support from the product in the future."
"The price of the solution is expensive. It can improve by reducing the price."
"The lock in is very, very tight. It is impossible to move out of Mimecast to a different product, like Proofpoint or 365 ATP, and keep the chain of custody for every email that I've archived."
"Its pricing can be improved. It is a bit expensive."
"The solution's console interface was recently changed for the admins, but the previous one was much better because we could open tabs on it."
"We have subscribed to an archival service, and yet, when we have to get our data out, we have to pay a fee to get our own data."
"They could provide a unified licensing model, including all the security features."
"Its pricing can be improved. It is a bit expensive."
 

Pricing and Cost Advice

"The pricing appears fair, and they demonstrate a genuine willingness to work with us on it."
"Abnormal Security, on the other hand, provides the same level of functionality for just over $60,000 – that's half the price!"
"Overall, we'd certainly prefer lower pricing, but Abnormal Security doesn't seem unreasonable compared to similar offerings in the market."
"The license is based on the user count, so the number of users that have an email address in the organization."
"The product price is moderate. I rate the pricing a five out of ten."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"The customers can select the license packages as per their requirements."
"It is a bit expensive."
"Its price is in the middle range. It is a structured licensing model where there are various components that you can add or choose to add or not."
"For what it is, the product is overpriced."
"The licensing costs are per-user for the product that you get with them."
"The product has good pricing in terms of return on investment."
