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.

Reporting could be one of the areas for improvement, as they could put more reporting into Microsoft Exchange Online Protection (EOP) natively rather than requiring additional licensing or connecting to other parts of the Microsoft suite, but it depends on the license you have. There aren't significant concerns with Microsoft Exchange Online Protection (EOP), as it depends on what customers expect; if they expect more features, then it depends on what Microsoft 365 license they have. The important thing is to ensure they are using all the security features they get with their licensing. The basic one is Microsoft Exchange Online Protection (EOP). While it's nice to have more functionality, that's available through other licensing programs with Microsoft. While we'd prefer more features, as a basic tool, it's fine, but more advanced features come with the add-ons from other parts of the Microsoft 365 licensing. One feature that could improve Microsoft Exchange Online Protection (EOP) is automated malware detection, where it actually analyzes the file offline in a sandbox to determine if it's safe, potentially reducing false positives.

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."
"I have never encountered any stability issues with Abnormal."
"Ease of use is undoubtedly one of the most valuable features of Abnormal Security."
"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."
"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."
"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."
"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."
"What I like most about Microsoft Exchange Online Protection is its integration with Windows, so we have one central view for all alerts and incidents."
"The product protects against malware."
"It is an easy solution."
"The most valuable features of Microsoft Exchange Online Protection are the EOP, ATP, safe links, fishing, and antispam."
"We use the solution in all our environments. We use it for remedy tickets and give them updates. It was our main communication point."
"Microsoft EOP's most valuable feature is a shared mailbox."
"We can migrate seamlessly without any disruptions to our operations."
"It offers great security against malware and other threats."
 

Cons

"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."
"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."
"There could be room for improvement in enhancing integration with other cybersecurity tools."
"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 solution can be complex at times. It would be nice to have the on-server version. It needs to improve the stability as well."
"The tool is not 100% stable."
"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."
"I would like to get reports about vulnerable connections from our clients with information about domains, public IPs, etc. That would be highly useful."
"If a company wants to put in line back-to-back anti-spam solutions, they need to work on that part because Microsoft recommends either you use EOP as a front line or you don't use it."
"Some features, like encryption, are not available."
"Microsoft has some training portals, but more could be developed."
"The product could be more stable. Microsoft products could be more stable because sometimes, even though they are updating some things, we cannot find those updates."
 

Pricing and Cost Advice

"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."
"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."
"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 solution falls on the higher or more expensive side of the spectrum."
"Apart from the license fee for the solution, there are no additional costs."
"The price of Microsoft Exchange Online Protection is reasonable."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
"The price could be lower."
"The solution should reduce the cost."
"The solution is expensive but is backed by Microsoft's reputation."
