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

"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."
"I would recommend Abnormal Security."
"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."
"I have never encountered any stability issues with Abnormal."
"It protects us from being business email compromised, which is invaluable for maintaining our security."
"Initial auto-remediation allows us to auto-remediate before the email lands in the end user's inbox for a split second."
"Their ability to take things out of the mailbox and catch things much faster than users is excellent."
"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."
"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."
"In the current environment that the world is in, everyone is trying to hack everyone else, so Project+ definitely helps a lot there."
"It's good, it keeps the spam out."
"What I like about the integration is that it is directly into Microsoft 365, users can use their Microsoft 365 credentials to log into the portal and access their mail."
"The product is good. To date, we have not faced any challenges."
"Due to our specialized use case, that HIPAA dictionary really comes in handy."
"The platform's most valuable features are journaling and email archiving, effectively stopping phishing attacks."
"The initial setup is very straightforward."
 

Cons

"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."
"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 room for improvement in enhancing integration with other cybersecurity tools."
"There could be more selectable options and more granular selections available."
"The pricing for academic institutions and student mailboxes is challenging."
"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."
"There could be more selectable options and more granular selections available."
"They should improve the cookies management feature."
"Its pricing can be improved. It is a bit expensive."
"I did have a problem with Mimecast. That is why I was looking for an alternative solution because their sender IP address gets poorly rated by Microsoft."
"The product's interface could be improved to be more user-friendly."
"Lately, Mimecast's outbound mail servers have been regularly blocklisted by spam filters. That didn't happen a few years back, but it seems to be a more frequent problem these days. When a server is blocklisted, it means all of my outgoing mail ends up in the recipient's junk mail. That affects my reputation and business confidence."
"The system is not user-friendly because you have to create policies that are mapped in a dictionary."
"We discussed the phishing aspect, the DNS system, and the key rotation."
"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 charge an extraction fee."
 

Pricing and Cost Advice

"The pricing appears fair, and they demonstrate a genuine willingness to work with us on it."
"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."
"Abnormal Security, on the other hand, provides the same level of functionality for just over $60,000 – that's half the price!"
"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."
"We pay monthly fees to our provider."
"The customers can select the license packages as per their requirements."
"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."
"It is a bit expensive."
"The solution is expensive."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
