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.

Very good threat protection, spam filtering, and cloud backups
Considering it integrates with Azure, I would like to be able to effectively set up policies where people are by default included in certain settings. For instance, for email quarantine, I can't set up a global setting. Users must go through an induction session where I guide them in configuring quarantine alerts rather than having default settings based on group membership. This seems like an oversight since they already use Active Directory details. They should assign policies based on group membership, which configures these settings by default.
Nadeem Syed - PeerSpot reviewer
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

"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."
"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."
"The product's scalability is good."
"It also gives the vulnerability status according to the versions you have selected. Let's say you have Google Chrome. It mentions the versions it has, and it updates. Within two hours of an update, it is reflected in the dashboard. That's really nice to have."
"The risk level notifications are most valuable. We get to know what kind of intrusion or attack is there, and we can fix a problem on time."
"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."
"Our customers are satisfied with Defender for 365 because Microsoft products are easy to use and customize to meet the client's needs. Everything is in one place, so we can adjust policies as needed for phishing, DLP, ATP, or any other security features that our clients want to apply."
"My experience with customer support and technical support for Microsoft Defender for Office 365 has been excellent."
"The most helpful aspect for me is the out-of-the-box configuration, which is fairly good."
"When we got the service, it included the email archiver with unlimited storage."
"The solution is straightforward to set up."
"Barracuda email protection is stable. I would give it a nine because of its strong cybersecurity features."
"The product is easy to deploy and maintain."
"The archiving and search features are very good."
"I would rate the solution nine out of ten."
"The most valuable aspect includes attempts to spoof or compromise domains from external sources."
"The email and the signature based protection is the most valuable feature."
"Trend Vision One has helped to reduce my time to detect and respond to threats; it was our gateway for almost 12 years."
"The interface is really good."
"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."
"Trend Micro Email Security’s most valuable feature is spam filtering."
"Some people can hack our system by sending emails from our domain to our domain. This is blocked completely by Trend Micro."
"The solution's most valuable feature is ATP (Advanced Threat Protection), which utilizes the machine learning algorithm."
"The technical support is good."
 

Cons

"Configuration requires going to a lot of places rather than just accessing one tab."
"Too many false positives and lacks an accurate capability to detect malicious SharePoint sites."
"Microsoft Defender for Office 365's Mac functionality requires improvement to deliver the same level of protection found on Windows devices."
"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."
"The UI needs to be more user-friendly."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"We need to be able to whitelist data at the backend."
"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."
"I would like to see better integration with other products."
"They could simplify the licensing and the pricing."
"Considering it integrates with Azure, I would like to be able to effectively set up policies where people are by default included in certain settings."
"The customer service and support could be improved if the support were available directly in Europe. Currently, the support is often managed from India, so we sometimes need to wait due to the time zone difference. It would be quicker and better if the support were provided by European staff."
"The solution's graphical user interface (GUI) could be improved visually."
"Barracuda Email Protection needs better reporting and more robust integration with security awareness training platforms and third-party solutions."
"Sometimes it is somewhat laggy, especially on the Archiver side. It should have improved performance on their Message Archiver."
"Two to three months back, we got fraudulent emails in which someone in the organization was being blamed."
"While they are good, not 100% of email is protected just yet."
"There is a limitation when customers are using their email from a third-party solution that isn't from Trend Micro."
"The company also needs to work on pricing because it is quite costly compared to other products."
"I would like to see more integration of Trend Micro Email Security with different platforms."
"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."
"The initial setup was straightforward. This is a virtual appliance, it takes a short time to deploy the solution. However, it is not difficult if you understand the technology. You must have good knowledge of the email security area to set up the product correctly. There are many features in this solution and a high risk of having mistakes with the configuration."
"They need to adjust the spam filtering and make it stronger."
"Trend Micro Email Security could improve by advancing its artificial intelligence in email security. There are rules that have to be configured. There should be less configuring."
