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.

Immediate results in patching promptly address vulnerabilities

When working with Tanium, there are some older devices that haven't been patched for a long time, and certain patches are not included in Tanium. I have to search outside to download patches, create bundles, and then perform the task. It would be easier if Tanium provided the patches directly. Some other brands provide the patch with a direct download link, which facilitates the process. Also, I feel that if there were more detailed documents and remediations readily available online for troubleshooting, especially more up-to-date information, it would be beneficial. Currently, some resources online are very out-of-date.

Quotes from Members

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

Pros

"The visibility into threats is also very impressive because Microsoft helps you predict things and provides analytics to help you really improve your security. And all of this technology works across the domain, so it is pretty helpful in terms of threat analytics."

"It reduces the risk of users accidentally clicking on phishing emails."

"It's a very scalable tool that can be used in a very small environment or in a very large environment. Everything can be managed from a simple dashboard and can be scaled up or down depending on the customer's environment."

"Vulnerability assessment and just-in-time access are some valuable features of Defender for server plans."

"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."

"The ability to hunt that IM data set or the identity data set at the same time is valuable. As incident response professionals, we are very used to EDRs and having device process registry telemetry, but a lot of times, we do not have that identity data right there with us, so we have to go search for it in some other silo. Being able to cross-correlate via both datasets at the same time is something that we can only do in Def"

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

"The summarization of emails is a valuable feature."

More Microsoft Defender XDR pros

"Tanium's most valuable feature is its instant discovery aspect."

"The security features are very valuable."

"The product is granular and can build complex roles compared to other EDR vendors."

"I'm not so familiar with the tool but I like the interaction of the console to the picture. Patching is the primary model I have been focusing on for the last couple of weeks. So I have created a proof of concept environment and have been checking the available features."

"Tanium’s best features include support for any Windows, Linux, or Mac endpoint, regardless of where it is, and the ability to do IT operations and security operations."

"I like the tool's incident response and security patching."

"I like the fact that you can create patching campaigns depending on the area of your network that you want to address first. I like the ability it has to make several campaigns that work in parallel."

"For incident response tasks, all these tasks can get done in minutes with minimal disruption to the end-user."

More Tanium pros

Cons

"There is no comprehensive visibility, making it less user-friendly."

"The mobile app support for Android and iOS is difficult and needs improvement."

"The customer support aspect can be better because it's the biggest complaint I hear about Microsoft. They can improve the ease of support and licensing processes."

"The licensing is a nightmare and has room for improvement."

"The automation response being slow is the main concern; when an incident occurs or if I run a remediation, it takes significant time to complete the remediation."

"Just like in any solution, the price can always be cheaper."

"Generally, antivirus products provide a central control to manage every device in terms of who is installing it or who is trying to disable it, but Microsoft doesn't have such a control center for the antivirus product it provides."

"The solution could enhance the threat Intelligence feature by making it more relevant to specific industries. Much of the threat intelligence information isn't directly applicable to our environment. It would be beneficial if the threat intelligence were tailored to the industry, such as healthcare or fintech, where the solution is being used."

More Microsoft Defender XDR cons

"The solution needs to improve the reporting and tracking capabilities."

"Any movement into a SaaS solution has challenges since the processes and data flows are not well defined. Hence, you need to build it at the same time."

"When working with Tanium, there are some older devices that haven't been patched for a long time, and certain patches are not included in Tanium."

"They could improve the UI."

"There are some bugs in the product. The tool needs to improve in the area of reporting."

"I would like to have more integrations and custom plugins to input. Integration is always a big deal in a lot of different environments."

"The main issues are the network connection because different customers have issues with their networks. It's difficult implementing this type of solution because the network is the main feature in the architecture for these types of solutions. Tanium could improve by creating some network optimization."

"When working with Tanium, there are some older devices that haven't been patched for a long time, and certain patches are not included in Tanium. I have to search outside to download patches, create bundles, and then perform the task."

More Tanium cons

Pricing and Cost Advice

"The bundling of software makes it easier to manage our setup, but Microsoft purposefully obfuscates this through marketing ploys to hide costs."

"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."

"Defender XDR is included in the E5 license, but it's a bit too expensive."

"Microsoft Defender XDR is included in our license."

"Defender plan 1 is tenant-wise, and Defender plan 2 is per-user, which makes it more expensive. To have certain features, you would need to purchase the E5 license. For all of the capabilities that the tool provides, the price, though it can be high, is fair."

"Microsoft Defender XDR is already included in our Office 365 licensing. It is better because we're saving money by using it."

"While the standalone price of Defender XDR might seem high, its value becomes clear when considering the ease of implementation and smooth integration with our existing Microsoft infrastructure, especially when bundled with other Microsoft products."

"Microsoft Defender XDR's licensing is complicated."

More Microsoft Defender XDR pricing and cost advice

"The product's pricing differs from region to region depending on negotiations and the number of endpoints."

"Tanium is a more expensive solution in Latin America than some of the competitors, such as BigFix."

"There is an annual license required to use this solution."

"The solution is expensive but it's a good investment."

"It's an expensive solution. It would be nice if the cost were lower."

"It is higher than some competitors in the market."

"The solution offers value for money."
