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.

Helps us stay compliant, has excellent malware detection, and is stable
The solution helped our organization stay 100 percent compliant with industry standards. MetaDefender Email Security can be set to be very aggressive for identifying attacks. This can be done based on how we want it. If we set it to this level, most of our emails will be blocked because the system will block anything that looks suspicious. We will also need to set the spam severity. This is the severity of everything, including phishing, spoofing, and other types of attacks. I would give the solution's ability to identify attacks a nine out of ten. MetaDefender helps us improve our spam catch rate. Any spam we receive is usually due to user subscriptions. We can specify rules of exclusion to meet our requirements as well. It also detects and blocks the links with suspicious codes. MetaDefender Email Security's multi-scanning capabilities for malware detection work based on how we set the parameters. The solution perfectly detects malware. MetaDefender can identify and disarm emails in zero-day attacks.

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 benefit that stands out to me is the ability for multiple individuals to collaborate simultaneously within the same document. Additionally, there is the option to save the document directly in the integrated OneDrive or SharePoint."
"Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable."
"The solution is very easy to use. All you have to do is to assign the license to the end-user and it's done. The customer will only have the feature activated, and the solution will monitor the emails to determine if they are a threat or not."
"There are several features that I consider valuable."
"The technical support is good and quick to resolve issues."
"Microsoft Defender for Office 365 has improved my organization's security. It makes it easier to manage the infrastructure without the help of third-party applications."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"The product is not resource-intensive."
"The sanitization is very good."
"The most valuable feature is called summary reconstruction which is used to deliver encrypted files to users."
"The most valuable feature of MetaDefender Email Security is the CDR. Customers purchase this solution specifically for data communication, as the other features can be obtained through other technologies that most customers already possess. Therefore, data communication serves as the foundation for the platform."
"The most valuable features include email filtering to block spam and phishing attempts, the use of DMARC for email authentication, and robust malware scanning."
"The best features are that it is very convenient to configure new rules onto it and it gives very good insight on what has entered my system and what the email security solution has taken action upon."
"The tool provides a strong defense against attacks. It is also easy to use. Trend Micro Email Security's integration capabilities are great."
"The initial setup is not overly complex."
"Trend Micro Email Security has a feature for secure protection of OneDrive, Google Drive, and CloudApp security."
"Trend Micro has inter-domain security features that solutions from other vendors like Forcepoint lack."
"The interface is really good."
"The integration capability of the solution is good."
 

Cons

"They can improve their security in a way where a customer can know if all their attachments are safe or not to open through a report. The solution does its job perfectly, but it never reports to the customer whether those attachments have been stopped before or not."
"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."
"In the areas of improvement for Microsoft Defender for Office 365, the console is the biggest challenge for me."
"Several simulation options are available within 365, and the phishing simulation could be better."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"We need to be able to whitelist data at the backend."
"The phishing and spam filters could use some improvement."
"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."
"Although the number of AV engines is good, it could be better."
"The DLP should be upgraded and has room for improvement."
"They offer a feature called SmartLink neutralization. I have tried it before. It seemed to work most of the time; however, I had a few users for whom it just wouldn't work. Whenever they click on a link, it stays on the MetaDefender page, saying that it's scanning it and never moves forward."
"The tool's dashboard is old."
"In our company, we found out that the solution wasn't well-tested by Trend Micro, resulting in a performance and bandwidth problem."
"The capacity handling and the scalability of the solution need to be improved since I feel Trend Micro lacks in such areas."
"The patch management could improve in Trend Micro Email Security."
"Trend Micro Email Security can improve on scam detection. It could use AI in this area."
"There is room for improvement in threat detection, especially for advanced attacks and business email compromise."
"The solution's configuration policy should be easier."
"I rate Trend Micro support four out of 10. The support in our region isn't very good. They do not respond quickly when we open up a case."
 

Pricing and Cost Advice

"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"The pricing is normal. Considering its popularity, it's not overpriced."
"I know that the product is incredibly expensive."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"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 product is very expensive."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"According to our customers, the price of MetaDefender is high and it continues to increase by almost 15 percent each year."
"Trend Micro Email Security's pricing is reasonable."
"The solution's pricing is very optimum, given its quality, features, and stability."
"The price of Trend Micro Email Security is more than Sophos' similar solution."
"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 cost is about $6,000 for 300 users for one year."
"The tool must improve its pricing."
"Trend Micro Email Security is not an expensive solution."
"The price of Trend Micro Email Security is annual. There are no additional fees."
