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.
Mike Bulyk - PeerSpot reviewer
Can quickly identify, track, tag, and categorize internal emails. Reporting accessibly via the main dashboard would be a great addition.
If Cisco could continue to develop integrations, whether it's internal tooling, Threat Grid, or AMP reporting which could be accessible via a single web page, that would be helpful. This would essentially add additional context on messages as well as files or links being detected. Potentially adding additional context on why certain messages are tagged as spam or malware. In our case, malware hasn't been detected yet, but spam certainly has been. Knowing what engines or which components of the message make it identifiable as spam, that could be useful. Additional context and reporting accessibly via the main dashboard would be great. There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools. There is also some room for improvement needed in terms of the reporting.

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 ability to respond to threats if very important."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"My experience with customer support and technical support for Microsoft Defender for Office 365 has been excellent."
"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"Since we have started using the solution, there have been fewer compromises."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"Defender for 365 is a comprehensive cloud-based solution. The value of the cloud is that you aren't alone. Threat intelligence and analytics are shared in the cloud. We don't have to find the solution alone. If you face an unknown threat with traditional solutions like Trend Micro and Symantec, you need to open a case and send your information to them to analyze forensically and identify the source of the attack."
"The initial setup is straightforward. You just add the license, click it, and then you can set up the rules. It is quite simple."
"I highly recommend it as one of the best choices."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"It's very easy to deploy and configure."
"This solution is easy to use."
"It has an efficient email filtering feature."
"The product offers protection, email security, anti-spam, and antivirus."
"The solution is stable."
"The most valuable features of the solution are spam protection and email continuity."
"Trend Micro Email Security scans all email attachments because, nowadays, ransomware or malware files are sent through email attachments."
"The most valuable feature of Trend Micro Email Security is effective phishing prevention."
"The interface is really good."
"The solution's initial setup process was easy since it was deployed on the cloud."
"The solution's most valuable feature is ATP (Advanced Threat Protection), which utilizes the machine learning algorithm."
"Since implementing it, we've seen a significant improvement in security. We no longer receive spam emails, and we're protected from various cyberattacks, including ransomware and social engineering."
"The integration capability of the solution is good."
 

Cons

"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 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."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"Several simulation options are available within 365, and the phishing simulation could be better."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"Too many false positives and lacks an accurate capability to detect malicious SharePoint sites."
"One area for improvement is integration. For example, when it comes to external SaaS platforms, we were not able to get a lot of information on integrations with such apps for security and authentication."
"They have moved features from one console to another. Things have been moved around in the interface and it takes me time to find where certain features are."
"We encounter issues while searching for missing emails."
"This solution could be improved by integration with Sandbox."
"The solution is a bit expensive."
"Cisco Secure Email Cloud Mailbox can improve by adding advanced phishing, then the solution would become the best in the market. However, this could increase the price even more. Additionally, if CES with domain protection could be added it would be an even better solution."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"The physical appliance has been discontinued, although the platform still exists."
"There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools. There is also some room for improvement needed in terms of the reporting."
"The search area has room for improvement. When you go to the next page, it remains at the bottom of the current page that you're on. Also, under the reports section, it allows you to see any "convictions," but if you want to search for those convictions you have to remember when they all came in and go back and edit the search accordingly. You cannot click on the list of convictions to actually see if you had a spike at a certain time."
"In our company, we found out that the solution wasn't well-tested by Trend Micro, resulting in a performance and bandwidth problem."
"I would like to see more integration of Trend Micro Email Security with different platforms."
"The capacity handling and the scalability of the solution need to be improved since I feel Trend Micro lacks in such areas."
"Trend Micro Email Security should introduce new features, improvements, and updates which are cost-effective and easy to deploy."
"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."
"The product must provide better customization features."
"It is a bit expensive than the market price."
"There is room for improvement in mobile device management. The company also needs to work on pricing because it is quite costly compared to other products."
 

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 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 has become expensive."
"The license is expensive because the cost is based on the number of users."
"The pricing is normal. Considering its popularity, it's not overpriced."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"Cisco Secure Email Cloud Mailbox does not have any competition with Sophos, Trend Micro, or other vendors of the world. However, there is a pricing premium for the solution. One has to look at it from that angle that while they are buying Cisco, there will be a premium, and Cisco justifies that premium value. That's why they're charging a high price."
"The solution’s pricing is manageable."
"The feedback from vendors and customer is that it is expensive."
"It is expensive compared to other vendors."
"Trend Micro Email Security is not an expensive solution."
"It's a VPN solution. Trend Micro is reasonably priced."
"The price of Trend Micro Email Security is annual. There are no additional fees."
"The cost is about $6,000 for 300 users for one year."
"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."
"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."
"The solution is inexpensive so we recommend it to small to mid-sized businesses."
"Trend Micro Email Security's pricing is reasonable."
