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.

Email Security Engineer at Logic Infosecurity
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."
"I have never encountered any stability issues with Abnormal."
"Their ability to take things out of the mailbox and catch things much faster than users is excellent."
"Initial auto-remediation allows us to auto-remediate before the email lands in the end user's inbox for a split second."
"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."
"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."
"Ease of use is undoubtedly one of the most valuable features of Abnormal Security."
"The solution is scalable."
"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 initial setup is easy."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
"The piece that is most valuable from the Mimecast standpoint will be the sandboxing feature."
"It's good, it keeps the spam out."
"I would rate Mimecast Email Security a nine out of ten."
"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."
 

Cons

"One feature I'd love to see is outbound scanning."
"The biggest pain point for us is the lack of support for on-premise email systems."
"There could be room for improvement in enhancing integration with other cybersecurity tools."
"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."
"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."
"I would like to have the ability to customize the auto-remediation feature."
"The solution is expensive in comparison to similar solutions."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"We discussed the phishing aspect, the DNS system, and the key rotation."
"The attachment scanning feature doesn't work properly."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"Technical support has been slower than it was in the past, likely due to the pandemic."
"Its pricing can be improved. It is a bit expensive."
"The system is not user-friendly because you have to create policies that are mapped in a dictionary."
 

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 licensing costs are per-user for the product that you get with them."
"The customers can select the license packages as per their requirements."
"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."
"The price of Mimecast Mailbox Continuity is expensive."
"I'm always going to say the price needs to be lower, but it's reasonable."
"The product has good pricing in terms of return on investment."
"It is a bit expensive."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
