Featured Reviews

William Schellhaas - PeerSpot reviewer
Senior Director of IT at Crunch Fitness West Florida and Atlanta (CR Fitness)
Provides comprehensive email security management, effective in detecting a wide range of email threats
The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails. This means Abnormal Security would assess emails before they reach my inbox, even if it happens slightly after Microsoft's initial scan. Currently, the process isn't seamless. Microsoft analyzes emails and delivers legitimate ones to my inbox. Abnormal Security then scans these delivered emails, and if flagged as malicious, they disappear. This creates a problem for our ticketing system mailbox, which is a third-party service. Emails sent to the ticketing system address are automatically forwarded by Microsoft. However, if these emails are malicious, Abnormal Security only cleans them from my Outlook mailbox after they've been forwarded. Since we primarily rely on the ticketing system and not the Outlook mailbox, these malicious emails still reach the ticketing system.

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 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."
"I would recommend Abnormal Security."
"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."
"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."
"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."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
"Mimecast certainly helped my customers reduce phishing emails."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"We like the content filtering and secure messaging features."
"The initial setup is very straightforward."
"It's good, it keeps the spam out."
"The solution offers good technical support."
"I have been satisfied with Mimecast Email Security as a good solution."
 

Cons

"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."
"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."
"There could be more selectable options and more granular selections available."
"The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails."
"There could be room for improvement in enhancing integration with other cybersecurity tools."
"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."
"One feature I'd love to see is outbound scanning."
"The system is not user-friendly because you have to create policies that are mapped in a dictionary."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"Many of our users complain that the system is blocking too many attachments. It's a good practice from a security perspective, but our users think Mimecast is doing too much. It might be something we'll have to adjust."
"The solution is complex and not easy to use."
"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."
"The attachment scanning feature doesn't work properly."
"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."
"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 license is based on the user count, so the number of users that have an email address in the organization."
"Overall, we'd certainly prefer lower pricing, but Abnormal Security doesn't seem unreasonable compared to similar offerings in the market."
"Abnormal Security, on the other hand, provides the same level of functionality for just over $60,000 – that's half the price!"
"The pricing appears fair, and they demonstrate a genuine willingness to work with us on it."
"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."
"For what it is, the product is overpriced."
"I'm always going to say the price needs to be lower, but it's reasonable."
"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."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
"It's an expensive solution."
