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.

Layered email security has protected sensitive research and still flags phishing in real time
The valuable features of Microsoft Exchange Online Protection (EOP) include providing an additional layer of protection, as it builds on the basic Exchange level of security that allows us to get our work done. Another feature I appreciate is the ability to question things, as our Exchange server allows us to identify in real-time if an email is a phishing email or spam email. It really helps us identify risks, especially through our external exchanges via email or through our cloud-based platforms. Our Exchange system blocks any embedded AI from all our applications and products, so we cannot use embedded AI in our daily work from our official laptops because we have secure information. The system is quite locked down.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"I would recommend Abnormal 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."
"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."
"Their ability to take things out of the mailbox and catch things much faster than users is excellent."
"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 valuable features of Microsoft Exchange Online Protection (EOP) include providing an additional layer of protection, as it builds on the basic Exchange level of security that allows us to get our work done."
"In general, my company is happy with Microsoft support...My company hasn't faced any stability issues with the solution."
"The email policy configuration options in Microsoft EOP are satisfactory."
"Microsoft Exchange Online Protection (EOP) is the best email solution with more features and robust security, making it ideal for corporate use."
"We use the solution in all our environments. We use it for remedy tickets and give them updates. It was our main communication point."
"I like the product's ZAP feature."
"It offers great security against malware and other threats."
"Overall, I think it's really a great product."
 

Cons

"There could be room for improvement in enhancing integration with other cybersecurity tools."
"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."
"The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails."
"The pricing for academic institutions and student mailboxes is challenging."
"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."
"I would like to have the ability to customize the auto-remediation feature."
"The biggest pain point for us is the lack of support for on-premise email systems."
"There could be more selectable options and more granular selections available."
"Not all settings can be configured automatically and most still require manual configuration. However, there is an automation tool available that can be used to input all the configurations either as a script or a tool it would be helpful."
"The user interface of Microsoft Exchange Online Protection (EOP) has room for improvement, as at times it doesn't make sense where to go to access certain features."
"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."
"The product needs more granularity. Some features, like encryption, are not available."
"It wasn't easy or intuitive enough for me to start using it. So, the reason was that the solution changed."
"The solution must improve the user experience."
"The price could be lower."
"I think the implementation could be more streamlined."
 

Pricing and Cost Advice

"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 pricing appears fair, and they demonstrate a genuine willingness to work with us on it."
"The license is based on the user count, so the number of users that have an email address in the organization."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
"It is a low-price solution."
"The product is bundled with Microsoft 365."
"The solution is priced high and could be less expensive compared to other solutions."
"The solution falls on the higher or more expensive side of the spectrum."
"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."
"It's a high price."
"Microsoft Exchange Online Protection's pricing is a little bit more because its price has recently increased."
