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

"Initial auto-remediation allows us to auto-remediate before the email lands in the end user's inbox for a split second."
"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."
"It protects us from being business email compromised, which is invaluable for maintaining our 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."
"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."
"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."
"I have never encountered any stability issues with Abnormal."
"I would recommend Abnormal Security."
"The most valuable feature is the DMARC Analyzer."
"I have been satisfied with Mimecast Email Security as a good solution."
"The initial setup is very straightforward."
"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 product's most valuable features are impersonation protection and phishing countermeasures."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
"The solution is pretty straightforward to use and easy to set up."
"I would rate Mimecast Email Security a nine out of ten."
 

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."
"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."
"There could be more selectable options and more granular selections available."
"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 room for improvement in enhancing integration with other cybersecurity tools."
"The biggest pain point for us is the lack of support for on-premise email systems."
"For Abnormal Security as a product, I would say probably somewhere around a seven, as there are some other areas where they can improve to achieve a higher rating."
"Its pricing can be improved. It is a bit expensive."
"The price of the solution is expensive. It can improve by reducing the price."
"The interface isn't the best. How everything works on the back end is confusing."
"They could provide a unified licensing model, including all the security features."
"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."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"Certainly, the primary area needing improvement is Mimecast's customer support. Our experience as Mimecast customers has been less than satisfactory. Even when raising a priority ticket, the response time is unacceptably long, often taking around five to six hours. This level of service is disappointing. Additionally, there have been recurring service disruptions in the UK region, leading to extended email delays due to various service issues. This year alone, we've encountered such problems on approximately four occasions."
"The interface and the documentation could be improved. They can also include some more training resources and content like video. While setting things up, I had to search for the information quite a bit. It took me time to find the correct way to do something. The information is there, but it is sort of all over the place. They can create a better help knowledge base or help portal. It retains your email for 45 days. They can maybe increase this duration."
 

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 solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
"The solution is expensive."
"I'm always going to say the price needs to be lower, but it's reasonable."
"For what it is, the product is overpriced."
"The product price is moderate. I rate the pricing a five out of ten."
"It is a bit expensive."
"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."
"It's an expensive solution."
