Senior Director, Information Technology at a insurance company with 51-200 employees
AI has helped classify threat types more accurately but product ownership can improve
Ease of use is important, and Abnormal Security's responsiveness and ability to deliver solutions when issues arise are crucial. However, there is always room for improvement, as achieving a perfect 10 means there is no more room for enhancement. For Abnormal Security, it's about leveraging AI even more, which they are already working on in their roadmap.

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

"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."
"Their ability to take things out of the mailbox and catch things much faster than users is excellent."
"I have never encountered any stability issues with Abnormal."
"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 would recommend Abnormal 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."
"The features that appeal to me most are the combination of auto-remediation and Detection 360."
"It protects us from being business email compromised, which is invaluable for maintaining our security."
"I rate Microsoft Exchange Online Protection (EOP) nine out of ten."
"It is easy to configure, easy to use, easy to add exclusions, easy to track, and easy to add anything else if you want."
"The solution uses artificial intelligence and machine learning, so you don't need train it to detect something. The detection and response times are short. It's an excellent product."
"In general, my company is happy with Microsoft support...My company hasn't faced any stability issues with the solution."
"The initial setup is just a standard process."
"It has a really nice web-based administration console."
"We use the solution in all our environments. We use it for remedy tickets and give them updates. It was our main communication point."
"The scalability is pretty good; it does what it is supposed to do."
 

Cons

"I would like to have the ability to customize the auto-remediation feature."
"The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails."
"The biggest pain point for us is the lack of support for on-premise email systems."
"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 room for improvement in enhancing integration with other cybersecurity tools."
"There could be more selectable options and more granular selections available."
"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 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 reporting needs a little bit of improvement."
"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's end-of-life cycle could be extended."
"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 tool's classification for bulk email is cumbersome."
"Besides price, the main room for improvement includes the sandbox or something similar; the usability that solutions are focused on."
"Having orchestration features added to Microsoft Exchange Online Protection, particularly automation and remediation, would be quite useful."
 

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."
"It is a low-price solution."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
"Apart from the license fee for the solution, there are no additional costs."
"The solution should reduce the cost."
"The solution's pricing is subscription-based rather than a yearly licensing cost. Pricing is based on the size of the environment and company and can be expensive."
"The product's pricing is competitive for the US market."
"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."
