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.

Have found the AI analyst and detection functions highly valuable for network operations while managing complexity in initial setup
The functions I find most valuable in Darktrace ( /products/darktrace-reviews ) are the AI analyst as well as the detection.The autonomous response capabilities of Darktrace are not crucial for me because it doesn't work in a network where there are no core switches. In a modern network, the autonomous response doesn't work, especially when sitting in a shared data center.If I'm running a traditional network where I am not in a shared data center with a layer two dedicated for my resources, then it can work for me. However, if I am in a data center where I don't have layer two, it becomes an issue because the autonomous response is reliant on sending spoofed TCP resets to my core switch to block traffic, which is a major issue.

Quotes from Members

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

Pros

"Does a thorough job of examining email and URLs for malicious content."
"Microsoft Defender for Office 365's most valuable feature is its performance."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"It gives us visibility into threats and, for endpoints, it helps us to prioritize threats. We used to have a lack of visibility, but now our time to detect and respond has decreased."
"The most beneficial feature in Darktrace is identifying phishing emails with the help of the AI engine and machine learning."
"It has helped the organization to detect any malware affecting the machines...The network monitoring and the email monitoring features are very valuable for us."
"A simple, powerful AI solution that just does all the work for you when you turn it on."
"Darktrace provides better visibility into network risks, allowing you to take preemptive action against risky user behavior."
"The most valuable feature is that it works autonomously."
"The most valuable feature of this solution is that it does not require human intervention to eliminate a threat."
"AI analytics are built directly into the product."
"The main valuable feature is that we don't need a lot of analysts. With few analysts, we have all the network monitored, 24/7."
"The solution provides protection with its Email Track Records and Machine Manual features."
"With Trend Micro email security gateway, we can deploy features like DLP and BEC."
"With Trend Micro email security gateway, we can deploy features like DLP and BEC."
"The technical support services are excellent."
 

Cons

"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."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"It would be better if it were more scalable. It depends on the architecture, but we would like to make it more scalable for both data centers."
"The product must provide better malware detection."
"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 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."
"Configuration requires going to a lot of places rather than just accessing one tab."
"In the areas of improvement for Microsoft Defender for Office 365, the console is the biggest challenge for me."
"One thing that I would like to look at going forward is to have a fully automated network infrastructure that is monitored automatically real-time, and that gives me this kind of capability where I would be able to look at my network at any given time and see the state of my network. With Darktrace, at the moment, I have to almost put in a date and tell them that want you to give me data from this date to this date. I don't want that. I want a fast solution in which it doesn't matter when I log into the application. Whenever I log in, I must be able to see my network and run a report. In other words, if I go in now and I say, "Give me a full report of what happened today, it must be able to give me that. It mustn't just be limited to a seven-day period, for argument's sake. It must be able to give me real-time and day-to-day tracking of what has happened within my network."
"Its documentation is not up to the mark. At times, I have a lot of trouble finding a solution. Even when I posted questions on the community chats, it took a lot of time for me to get answers. That's something that can be improved. Darktrace can focus on creating a more interactive community. If there are more people from Darktrace to focus on community chats, it would be better."
"Darktrace needs significant improvement in its notification capabilities."
"Darktrace could improve its features, such as monitoring and detecting ransomware."
"We'd like threat hunting, and we'd like to see a global solution that can automate vulnerability scans. I know it is something they are working on."
"I was under impression that Darktrace's automatic blocking would be an out-of-the-box feature, but we had to integrate it with our firewall to get it to block automatically. The salesperson should be upfront and explain that you need to integrate it with your network. I would also like to see more reporting on risk. Banks in my region want to see at a glance the risk level of various assets."
"I think there is some MSSP missing."
"The main portal needs improvement as it is difficult to use."
"The solution's pricing could be improved."
"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."
"The product's pricing could be more flexible."
"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."
