Tolu Omolaja - PeerSpot reviewer
Great URL scanning and attachment scanning, but I would like more proactive threat analysis
The two main features that prove most beneficial for us are URL scanning and attachment scanning. URL scanning involves an automatic scan of links and emails. When a user clicks on a link within an email, the system promptly checks the link's safety. If the link is deemed safe, access is granted automatically. However, if it is flagged as unsafe, we receive feedback and notification to caution us about the potentially harmful link. At this point, we are presented with the option to proceed or return. I have personally witnessed the system identify a few unsafe links, making this the primary advantage of using the solution. The second crucial aspect is the scanning of attachments. When an email containing an attachment arrives, we receive a notification of the new email, along with information that the attachment is being scanned for threats. This additional layer of security provides peace of mind for our organization. While Microsoft Defender for Office 365 offers numerous features, these two stand out as particularly impressive and valuable to us.
William Schellhaas - PeerSpot reviewer
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.
LARK IT - PeerSpot reviewer
Easy to setup, stable and highly scalable
The ability for users to look at their own quarantine box needs improvement. So at the moment, it doesn't give you the ability to see every email that has been quarantined. No end-user has the ability to see what's being quarantined. It's only people who have access to the back-end platform that can actually see what has been quarantined. The end user doesn't know if they have an email that has been quarantined, only if they're expecting something that didn't come through. In future releases, I would just like to see that ability for users to see what's being quarantined and what's not quarantined but safe. Just those genuine false positives.

Quotes from Members

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

Pros

"The product is not resource-intensive."
"Threat Explorer is an invaluable tool for me, and it plays a crucial role in helping me discern the origins of various email campaigns, pinpointing where they emanate from, and identifying the individuals within our organization who are affected."
"Does a thorough job of examining email and URLs for malicious content."
"The product's scalability is good."
"Since we have started using the solution, there have been fewer compromises."
"Microsoft Defender for Office 365 helps people to work remotely. It is a secure solution. We don't need to use our company's computers or get VPN connections to the networks. I can control how they share screens and what they send to the devices. It keeps our organizations confidential and sensitive information safe."
"Defender for Office 365 has helped eliminate having to look at multiple dashboards and that is the aspect I like most about it. It is simpler, effective, and convenient. The users like the process efficiency."
"The initial setup was easy."
"Ease of use is undoubtedly one of the most valuable features of 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."
"I would recommend Abnormal Security."
"Their ability to take things out of the mailbox and catch things much faster than users is excellent."
"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."
"The features that appeal to me most are the combination of auto-remediation and Detection 360."
"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 have never encountered any stability issues with Abnormal."
"I like its ability to detect and block."
 

Cons

"You should be able to deploy Defender for every subscription without the need to add servers."
"I'd like some additional features any product can give me to protect our environment in a better way."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats. For example, information about best practices on how to protect their own devices against hackers and scammers, such as educational information or training. This would help others have a better understanding of cyber security. Additionally, there can be more security features added."
"The pre-sales cost calculations could be more transparent."
"We noticed that from time to time, Microsoft's stability does have problems. Sometimes the service goes up and down. Sometimes they change without prior notice."
"Configuration requires going to a lot of places rather than just accessing one tab."
"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."
"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."
"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."
"There could be more selectable options and more granular selections available."
"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."
"There could be room for improvement in enhancing integration with other cybersecurity tools."
"The ability for users to look at their own quarantine box needs improvement. So at the moment, it doesn't give you the ability to see every email that has been quarantined. No end-user has the ability to see what's being quarantined. It's only people who have access to the back-end platform that can actually see what has been quarantined. The end user doesn't know if they have an email that has been quarantined, only if they're expecting something that didn't come through."
 

Pricing and Cost Advice

"The product is expensive."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"I know that the product is incredibly expensive."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"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!"
"The pricing appears fair, and they demonstrate a genuine willingness to work with us on it."
"Overall, we'd certainly prefer lower pricing, but Abnormal Security doesn't seem unreasonable compared to similar offerings in the market."
"I would rate the pricing of Sublime Security as a seven out of ten. It is reasonably well-priced."
