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.
Amber Worth - PeerSpot reviewer
Retrieves data from quarantines and easy to read logs with robust security features
Some of the searchability when looking for specifics in Exchange logs is tedious. Although eventually the information is located, it can be difficult if detailed information is lacking. Improving the search process by allowing searches with different types of parameters and facilitating searches within emails would be advantageous. Simplifying interfaces would also be appreciated.

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."
"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 features that appeal to me most are the combination of auto-remediation and Detection 360."
"Their ability to take things out of the mailbox and catch things much faster than users is excellent."
"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."
"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."
"Microsoft EOP's most valuable feature is a shared mailbox."
"I like the product's ZAP feature."
"The pre-set policies and configuration analyzer are the most valuable features."
"The initial setup was easy. The configuration process is very straightforward."
"Microsoft Exchange Online Protection (EOP) is used essentially for email filtering, acting as an anti-spam and security product for email."
"We use the solution to receive emails. We do not use the calendar function as our clients are slow adaptors to the latest features."
"The most valuable feature is the ease of administration. Other solutions require complex administration, but Microsoft Exchange Online Protection is easier."
"The security features provided by Microsoft are robust."
 

Cons

"There could be more selectable options and more granular selections available."
"One feature I'd love to see is outbound scanning."
"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."
"The biggest pain point for us is the lack of support for on-premise email systems."
"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."
"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."
"I would like to have the ability to customize the auto-remediation feature."
"It doesn't protect against everything. We do need protection for, for example, endpoints."
"We have experienced issues while migrating from on-prem to the cloud. The tool needs to improve its stability."
"When the product is being updated, it changes some of the setups. The support team is also not good."
"Our company faces difficulty with Microsoft Exchange Online Protection (EOP) because it's too big, clunky, and difficult for a small client to implement quickly and easily."
"The security features could be better."
"I think the implementation could be more streamlined."
"The solution lacks to elaborate on its spam policies."
"The security compliance features need to be improved. Sometimes, a client's mailbox becomes full because of retained information and not because of mail. I would like to see improvement in block rules as well."
 

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."
"Regarding the price, it's comparable to other service providers. We've also looked at Check Point's offerings, and the pricing doesn't seem to be an issue."
"The pricing of the solution is reasonable."
"The product is expensive."
"Microsoft Exchange Online Protection's pricing is a little bit more because its price has recently increased."
"The solution is expensive but is backed by Microsoft's reputation."
"Online Protection is fairly expensive."
"The tool's pricing is excellent."
"The product is bundled with Microsoft 365."
