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

"I would recommend Abnormal Security."
"The features that appeal to me most are the combination of auto-remediation and Detection 360."
"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."
"It protects us from being business email compromised, which is invaluable for maintaining our security."
"I have never encountered any stability issues with Abnormal."
"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."
"In general, my company is happy with Microsoft support...My company hasn't faced any stability issues with the solution."
"We can migrate seamlessly without any disruptions to our operations."
"The most valuable feature of Microsoft Exchange Online Protection is the accidental release of information protection capabilities. Additionally, the solution is easy to use."
"The email policy configuration options in Microsoft EOP are satisfactory."
"We like the holding facility that is available for potentially suspicious URL's. This allows a real-time review to be performed before the email reaches a users inbox."
"You can use the product to create special accounts."
"The initial setup is just a standard process."
"The security features provided by Microsoft are robust."
 

Cons

"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."
"I would like to have the ability to customize the auto-remediation feature."
"There could be more selectable options and more granular selections available."
"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 biggest pain point for us is the lack of support for on-premise email systems."
"I would like to get reports about vulnerable connections from our clients with information about domains, public IPs, etc. That would be highly useful."
"Having orchestration features added to Microsoft Exchange Online Protection, particularly automation and remediation, would be quite useful."
"The solution lacks to elaborate on its spam policies."
"I think the implementation could be more streamlined."
"The solution must improve the user experience."
"The security features could be better."
"When the product is being updated, it changes some of the setups. The support team is also not good."
"The licensing can be on the expensive side, especially in the cloud space."
 

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!"
"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."
"On a scale of one to ten, where one is cheap, and ten is very expensive, I rate the pricing a six. For licensing, we can make monthly or yearly payments. Right now, we pay 5 USD per month to secure a person's license."
"The price of Microsoft Exchange Online Protection is reasonable."
"Online Protection is fairly expensive."
"The product is bundled with Microsoft 365."
"The product's pricing is competitive for the US market."
"The pricing for the solution depends on what you are trying to achieve with the use of the product, but I know that it is not a cheaply priced product. Yearly payments have to be made towards the licensing fees of the solution."
"The solution is priced high and could be less expensive compared to other solutions."
"It's a high price."
