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.

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.

Offers comprehensive security, easy integration, and good support
It integrated easily. About 99% of the time, we do not face any challenges in integrating any product of Trend Micro with the existing network. It is usually compatible with all kinds of networks. They have recently added AI to all Trend Micro products. It makes life a little bit easier by catching viruses, providing solutions, and helping out whenever you are stuck somewhere. It is one of the very good features they have right now. For example, one of our clients experienced a network attack and became confused about resolving the issues. The AI was helpful by suggesting initial steps to solve the problem.

Quotes from Members

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

Pros

"The deployment capability is a great feature."
"The email protection is excellent, especially in terms of anti-phishing policies."
"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
"Microsoft Defender for Office 365 is a stable solution."
"Scalability-wise, I do not think there are any issues so far."
"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"The product's scalability is good."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"The features that appeal to me most are the combination of auto-remediation and Detection 360."
"Ease of use is undoubtedly one of the most valuable features of Abnormal Security."
"Initial auto-remediation allows us to auto-remediate before the email lands in the end user's inbox for a split second."
"It protects us from being business email compromised, which is invaluable for maintaining our security."
"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."
"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 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."
"The tool provides a strong defense against attacks. It is also easy to use. Trend Micro Email Security's integration capabilities are great."
"The most valuable features of this solution are the antivirus, antispam, and integration with cloud services. This is a multifunctional solution."
"The interface is really good."
"Trend Micro Email Security’s most valuable feature is spam filtering."
"Trend Micro Email Security has a feature for secure protection of OneDrive, Google Drive, and CloudApp security."
"The most valuable features of the solution are spam protection and email continuity."
"It does a good job of ensuring users are not compromised via email."
"The most valuable features include email filtering to block spam and phishing attempts, the use of DMARC for email authentication, and robust malware scanning."
 

Cons

"Microsoft Defender for Office 365 must improve the overall management style, including the GUI. It also needs to change the filters so that it is easy to whitelist and blacklist data."
"The visibility into threats is not up to the mark, as I do not have control. I rate my experience with Microsoft Defender for Office 365 as six out of ten due to troubleshooting and pricing concerns."
"Microsoft Defender for Office 365 should improve the troubleshooting tools. It's unclear whether the device is blocked at the firewall level or at the device itself. The granularity needed for troubleshooting is currently lacking. From my perspective, Microsoft should address this issue to benefit many users who likely share the same sentiment."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"Microsoft sometimes has downtime, and we'll get several incidents coming in back to back. We have a huge backlog of notifications, many of which may be false positives. However, there might be serious alerts, so we can't risk dismissing all of them at once."
"The only thing they should improve is the licensing model. They should stop changing it. A year ago, the five features I mentioned were included in one product. Now, three of them are bundled into one product, and you have to pay extra for the other two. I don't mind paying extra, but I don't want them to change it every year or every six months. I need to know what I'm looking at and not worry about it next year."
"Microsoft wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"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."
"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."
"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."
"There could be more selectable options and more granular selections available."
"One feature I'd love to see is outbound scanning."
"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 patch management could improve in Trend Micro Email Security."
"It is a bit expensive than the market price."
"There is room for improvement in threat detection, especially for advanced attacks and business email compromise."
"While they are good, not 100% of email is protected just yet."
"There is a lot of room for improvement towards the phishing kind of email filtering, with the different hijacking attacks, and with the kind of password attacks which these phisher attackers do."
"The product must provide better customization features."
"There needs to be more documentation for the product."
"The tool's dashboard is old."
 

Pricing and Cost Advice

"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."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"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."
"I know that the product is incredibly expensive."
"The product is expensive."
"For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."
"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."
"Trend Micro Email Security's pricing is reasonable."
"It is expensive. The cost is per box, and it depends on how big your environment is. Prices range from 11 to 12 dollars for licenses and can fluctuate up and down, but for environments with 4,000 to 5,000 users, it can be between 6 to 8 dollars."
"Price-wise, it is a cheap solution. I rate the solution's pricing a one on a scale of one to ten, where ten is expensive. Annual payments are made for the licensing."
"The price is more accessible compared to some other solutions, like FortiMail. It offers excellent value for the price."
"The solution's pricing is very optimum, given its quality, features, and stability."
"Trend Micro Email Security is not an expensive solution."
"The tool must improve its pricing."
"The cost is about $6,000 for 300 users for one year."
