Featured Reviews

ChrisBrown5 - PeerSpot reviewer
Automated threat detection that protects against corruption with minimal intervention
Abnormal Security is valuable because it features an automated scoring tool that doesn't require much intervention from our team. It enhances threat detection capabilities by making the process automated and is easy to scale to our entire environment. Additionally, it protects us from being business email compromised, which is invaluable for maintaining our security.
Frank Rawson - PeerSpot reviewer
It gives clients peace of mind and helps them educate their users about threats
A few years ago, our team found the implementation to be somewhat challenging. It has gotten easier as we've grown more experienced. The difficulty depends on the expertise of the person doing it. I don't work with Mimecast every day, so it might be more difficult for me than it is for one of my techs who regularly does Mimecast implementations. It requires some specific in-depth product knowledge and an understanding of email solutions. The deployment time varies. In South Africa, it depends on who you use to deploy it. If you use one of Mimecast's local partners, it can take up to two weeks because of their process. However, it's only about four to eight hours of work. After deployment, there isn't much maintenance aside from supporting and educating your customers. Users require constant education on how to use the Mimecast client and release an email that has been blocked.

Quotes from Members

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

Pros

"Initial auto-remediation allows us to auto-remediate before the email lands in the end user's inbox for a split second."
"The features that appeal to me most are the combination of auto-remediation and Detection 360."
"I have never encountered any stability issues with Abnormal."
"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."
"It protects us from being business email compromised, which is invaluable for maintaining our security."
"Ease of use is undoubtedly one of the most valuable features of Abnormal Security."
"I would recommend Abnormal 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."
"The solution offers good technical support."
"The product is good. To date, we have not faced any challenges."
"It offers an easy initial setup."
"The biggest advantage of Mimecast Email Security is its spam filtering. Its filtering feature is interesting."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
"Due to our specialized use case, that HIPAA dictionary really comes in handy."
"It's good, it keeps the spam out."
"It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."
 

Cons

"I would like to have the ability to customize the auto-remediation feature."
"Abnormal should add more automatic reports. I have an open request to our account team for more notification and report types that can be sent automatically. For example, they have an awesome report that gets sent weekly, and I also want them monthly, so I don't need to do so much adding up when my director wants numbers over time."
"The pricing for academic institutions and student mailboxes is challenging."
"The biggest pain point for us is the lack of support for on-premise email systems."
"There could be more selectable options and more granular selections available."
"There could be more selectable options and more granular selections available."
"One feature I'd love to see is outbound scanning."
"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."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"As a user, the user interface of the management console could be upgraded, for example."
"Its pricing can be improved. It is a bit expensive."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"External security features need improvement."
"I'd like to have better support from the product in the future."
"The installation is not so straightforward."
"They should improve the cookies management feature."
 

Pricing and Cost Advice

"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."
"Abnormal Security, on the other hand, provides the same level of functionality for just over $60,000 – that's half the price!"
"The license is based on the user count, so the number of users that have an email address in the organization."
"For what it is, the product is overpriced."
"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."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"It is a bit expensive."
"The product has good pricing in terms of return on investment."
"We pay monthly fees to our provider."
"The customers can select the license packages as per their requirements."
"The solution is expensive."
