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.

Email defenses have reduced phishing risk and support strong compliance and user awareness
The improvement needed is not necessarily in the product itself, but rather around how other organizations have evolved. The DLP discussion is no longer limited to email; it has gone to border level with companies like Zscaler, Netskope, and Palo Alto giving the complete full-stack SASE setup. When somebody has a SASE setup, then Mimecast Advanced Email Security DLP might not even be needed at a point in time. Mimecast Advanced Email Security needs to improve in this area because they are only focusing on a particular set of problems which is on email and human risk, whereas companies that need a slightly bigger picture will look elsewhere. The second thing is when you buy an XDR provider, they give you a complete holistic story around it, showing what has happened, which email somebody has clicked on, whether there have been any changes, and whether there is any network activity. You get a holistic picture. When pushing Mimecast Advanced Email Security to end customers, people are more often saying that they would rather buy XDR from another provider because the story when an analyst sees is complete in terms of what they see, whereas they only get an email story from Mimecast Advanced Email Security. Mimecast Advanced Email Security has to improve there. Companies like Abnormal AI cover more on UEBA and user behavior, and there are many things for Mimecast Advanced Email Security to improve in this area as well. It is less of a technology issue; they are doing very well on email. The conversation for them to have is on how to get into a broader level or how to get a tie-up to become a broader supplier. At least from a service provider landscape, I can say that.

Quotes from Members

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

Pros

"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."
"Their ability to take things out of the mailbox and catch things much faster than users is excellent."
"Ease of use is undoubtedly one of the most valuable features of Abnormal Security."
"I would recommend Abnormal Security."
"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."
"The features that appeal to me most are the combination of auto-remediation and Detection 360."
"It protects us from being business email compromised, which is invaluable for maintaining our security."
"One of the things that I love about them is that the setup and installation are super easy. All you do is give them access to your Microsoft 365 tenant, and through APIs, they are able to do their work. They are doing all this through APIs, so you do not have to install the software and take a month to get it all set up to even see the value of the solution. You could be up and running in less than an hour."
"If I had to mention one or two things that bring the biggest benefit, I would say the security of the emails and dealing with everything."
"The solution's performance is good."
"I have been satisfied with Mimecast Email Security as a good solution."
"The most valuable feature is the DMARC Analyzer."
"The initial setup is easy."
"It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."
"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."
"Mimecast Mailbox Community is an email gateway required for every organization, regardless of size."
 

Cons

"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."
"There could be more selectable options and more granular selections available."
"I would like to have the ability to customize the auto-remediation feature."
"The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails."
"The biggest pain point for us is the lack of support for on-premise email systems."
"The pricing for academic institutions and student mailboxes is challenging."
"One feature I'd love to see is outbound scanning."
"We discussed the phishing aspect, the DNS system, and the key rotation."
"Mimecast Advanced Email Security needs to improve in this area because they are only focusing on a particular set of problems which is on email and human risk, whereas companies that need a slightly bigger picture will look elsewhere."
"Its pricing can be improved. It is a bit expensive."
"They could provide a unified licensing model, including all the security features."
"The product's interface could be improved to be more user-friendly."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"The price of the solution is expensive. It can improve by reducing the price."
"The price could be better, it should be reduced."
 

Pricing and Cost Advice

"The license is based on the user count, so the number of users that have an email address in the organization."
"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 pricing appears fair, and they demonstrate a genuine willingness to work with us on it."
"Two subscription options are currently offered: monthly and yearly. My suggestion is to opt for the yearly subscription as it can give some discount. The pricing isn't high as other cloud solutions are pricier than Microsoft's offerings."
"The product has good pricing in terms of return on investment."
"The customers can select the license packages as per their requirements."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
"Compared to the other products in the market, it is neither cheap but nor very expensive. I would rate it somewhere in the middle, 5 out of 10."
"The licensing costs are per-user for the product that you get with them."
"The price of Mimecast Mailbox Continuity is expensive."
"It is a bit expensive."
