Advanced threat hunting saves significant time in tracking and responding to incidents

Microsoft Defender XDR could be improved with a lower price. My main suggestion would essentially be what Copilot is providing, which is a single pane of glass, so I don't have to go to different windows. That's just a workflow consideration for me. It would be great to have all the information centralized into one particular data app. If I need to open up extra ones, I can, however, I would appreciate a future where everything I need is right there on one single pane of glass. Beyond that, there's really nothing else I see that I would want Microsoft to improve.

Client activity has been monitored efficiently through in-depth log analysis and traffic filtering

I use the Zscaler speed test, and it is very nice. We use some logs from Zscaler Client Connector to collect data and see what is happening, such as if there is an interruption or something. There is a specific tunnel version that we have to use because, depending on the internet provider, some of them have lower speed, so we have some issues. This is because of the provider, not from Zscaler. We use Office 365 services and Office applications, and because some connections are slow and they do not have full coverage from the internet provider, we have some issues. If the speed is slow for Zscaler Client Connector connection, then we have issues because if the speed is not good, then Zscaler Client Connector goes down. This may be because they put some policy. Of course, if you use Office 365 services such as Outlook, the minimum bandwidth is 5 megabits and more, so this causes issues if the users do not have a good remote connection. This depends on the companies and the users, so they need to fix it. This is not from us or our company. It is very useful, and the logs are very helpful. When we go to logs, we understand what is happening.

Quotes from Members

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

Pros

"You can configure the product very easily."

"Within advanced threat hunting, the tables that have already been defined by Microsoft are helpful. In the advanced threat hunting tab, there were different tables, and one of the tables was related to device info, device alert, and device events. That was very helpful. Another feature that I liked but didn't have access to was deep analysis."

"From an attack chain perspective, Defender XDR handles phishing and spam emails easily, while Defender for Endpoint manages endpoints effectively. We've drastically improved our user experience."

"Defender XDR has a feature called the timeline that lets you track all activities. It helps a lot with investigations."

"It provides a single pane of glass within the 365 admin interface, streamlining our experience by consolidating information in one place and eliminating the need to navigate through multiple interfaces."

"The most valuable feature depends on the scenario. For compliance, I like Microsoft Purview Information Protection and Data Loss Prevention. Sentinel is the most helpful feature for security. 365 Defender helps us prioritize threats across an enterprise. It's a crucial feature for the managed services team."

"In our company,we have faced multiple attacks over the last few months, but none of them have been successful, and I think Microsoft Defender XDR has played a major role in it."

"The most valuable feature is the DLP because that's where we can have an added data protection layer and extend it not just to emails but to the documents that users are working on. We can make sure that sensitive data is tagged and flagged if unauthorized parties are using it."

More Microsoft Defender XDR pros

"The solution operates in the background seamlessly without the user noticing."

"The real-time analytics feature in Zscaler Client Connector is another valuable feature called Digital Experience, or ZDX, which can easily identify the root cause of issues accessing public or internal resources and provide good analysis so relevant teams can quickly resolve them, making it a very good tool that helps customers."

"It is very useful, and the logs are very helpful; when we go to logs, we understand what is happening."

"Zscaler Client Connector is quite scalable, and I would rate its scalability as nine or ten out of ten."

"It is very important to see what is happening between the user and the applications that we have, and to filter the traffic from outbound traffic and inside traffic."

"The best features of Zscaler Client Connector are that it gives the client a much more transparent experience, as they don't have to worry about connecting to a VPN."

"It is very important to see what is happening between the user and the applications that we have, and to filter the traffic from outbound traffic and inside traffic."

"It is very useful, and the logs are very helpful; when we go to logs, we understand what is happening."

Cons

"The licensing process needs improvement and clarification, as it is currently difficult to understand which features are licensed to which users."

"Because of the training model, Defender XDR's automatic response sometimes blocks legitimate users and activities. Also, the UI sometimes responds slowly."

"I haven't really come across the incident Q assistant helping improve the efficiency of my SOC workflow."

"The initial time spent setting up and configuring Defender XDR is a bit longer than the other solutions. If everything were on one portal, the platforms for managing policies or alerts would be simpler. We must automate and manage policies on Intune rather than the same portal."

"It would be beneficial to have a more seamless experience with everything consolidated in one place, particularly when dealing with aspects related to the Exchange console."

"We struggle sometimes with tier one support agents who give canned responses."

"Sometimes, configurations take much longer than expected."

"The solution could improve by having better machine learning and AI. Additionally, the interface, documentation, and integration could be better."

More Microsoft Defender XDR cons

"There is room for improvement regarding the price of Zscaler Client Connector, as it is one of the most expensive solutions available."

"Zscaler Client Connector is not low in cost; it is definitely on the higher side."

"There is a hard learning curve for Zscaler Client Connector; their support isn't the greatest all the time."

"The stability of Zscaler Client Connector needs improvement, as it often disconnects and reconnects."

"If the speed is slow for Zscaler Client Connector connection, then we have issues because if the speed is not good, then Zscaler Client Connector goes down."

"There is room for improvement regarding the price of Zscaler Client Connector, as it is one of the most expensive solutions available."

"If the speed is slow for Zscaler Client Connector connection, then we have issues because if the speed is not good, then Zscaler Client Connector goes down."

Pricing and Cost Advice

"Microsoft should provide lower-level licensing options. They should do it in such a way that even an individual could purchase a license, and it should be entirely flexible."

"The pricing of Microsoft 365 Defender is definitely on the costly side, but with the features and services that Microsoft provides, such as the seamless integration of all the Defender tools, while the price is on the higher side, there is no alternative."

"Licensing is somewhat confusing, particularly when presenting our pitch decks to stakeholders and leveraging key features in premium SKUs, but we managed with some assistance from Microsoft."

"The functionality is fantastic, but for medium and small-sized companies it's overpriced. It would be better if it were a little bit cheaper."

"The license cost for a year is approximately forty-four thousand, and this annual saving is a significant factor in our decision to switch."

"On average, we pay around 55 euros per user for the services and features we receive."

"The most valuable licensing option is expensive, so pricing could be improved. Licensing options for this solution also need to be consolidated, because they frequently change."

"365 Defender can get expensive because you pay per gigabyte of data ingested. On the other hand, much of the data available in the other Microsoft security solutions are made available relatively cheaply—sometimes at cost or for free. Integrating only a limited set of third-party solutions with Sentinel would be cost-effective. It's much more affordable if companies only have Microsoft stuff."
