Tanium and Microsoft Defender XDR are competitors in the enterprise security solution category. Microsoft Defender XDR appears to have the upper hand due to its comprehensive features and perceived value.

Features: Tanium provides real-time data visibility, endpoint management, and in-depth asset management, making it ideal for large networks. Microsoft Defender XDR offers integrated threat detection, automated response, and cross-platform security services, enhancing threat detection across multiple environments.

Room for Improvement: Tanium could improve its user interface and simplify its complex configurations. Its reliance on heavy infrastructure can also be a drawback. Microsoft Defender XDR can benefit from reduced false positives and enhanced analytics to better handle zero-day threats and threats outside the Microsoft ecosystem.

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 Currently, some resources online are very out-of-date.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

"For me, the advanced hunting capabilities have been really great. It allowed querying the dataset with their own language, which is KQL or Kusto Query Language. That has allowed me to get much more insight into the events that have occurred. The whole power of 365 Defender is that you can get the whole story. It allows you to query an email-based activity and then correlate it with an endpoint-based activity."

"The common and advanced security policies for threat hunting and blocking attacks are valuable."

"The 'Incidents and Alerts' tab is a valuable feature where we can find triggered alerts."

"It has been great for us. Previously, we didn't have a solution to protect us, especially from malware, whereas now, we are getting protection up front, especially from the malware attacks coming through emails or endpoints."

"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."

"I like that it's fully integrated with Windows, Microsoft 365 Exchange Online, and Outlook. It is better than other antivirus solutions because it's fully integrated with all Microsoft products. It's easy to integrate them and onboard all Windows devices from SCCM."

"Defender is easy to use. It has a nice console, and everything is all in one place."

"Microsoft Defender XDR is very comprehensive, covering a lot of the services, tools, and applications that we use, so it's very efficient, and it works out of the box."

More Microsoft Defender XDR pros

"The security features are very valuable."

"The most valuable features of this solution are the consolidation of all historical data on device endpoints, security drivers, firmware, and Software version gaps."

"Tanium has made the process of detecting threats more proactive with its detection. So, the process is easier and more efficient."

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

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

"When I push a quick update, it's done right away, and I can rescan immediately to confirm completion within minutes."

"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."

"I would say Tanium is the best tool for vulnerability management."

More Tanium pros

Cons

"I do think that maybe having a feature within my organization where there are three different domains within which we have to operate would be helpful, as there is currently no unified view within the domains."

"There are a few technical issues with Defender XDR that can be improved. Sometimes, the endpoint devices are not reporting properly to the Defender 365 portal. When you're getting all the information from the Microsoft portal, the devices are sometimes not in sync. We have hundreds of endpoint devices, some needing to be onboarded again."

"The abundance of sub-dashboards and sub-areas within the main dashboard can be confusing, even if it all technically makes sense."

"The support could be more knowledgable to improve their offering."

"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."

"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."

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

"The dashboard should be easier to use. There is also improvement needed in the reporting when it comes to exporting or scheduling reports."

More Microsoft Defender XDR cons

"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."

"Tanium's limitations should be improved because although it is a great tool, it is limited to only a few classes during a session."

"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."

"The performance could improve in future releases. We have had performance issues in specialized web environments, but overall I think the problems are less than 2% of the computer systems being used."

"They could improve the UI."

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

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

"We had some issues with the solution's OS upgrade."

More Tanium cons

Pricing and Cost Advice

"Understanding the subscription model has been a bit challenging, as every feature or requirement comes with an additional cost."

"Purchasing Microsoft Defender XDR as part of a Microsoft 365 bundle can be cost-effective, but acquiring it as a standalone product may be more expensive."

"Microsoft Defender XDR is included in our license."

"The product is fairly priced for what we get from it."

"The licensing fee for Microsoft 365 Defender is fair."

"They have moved from a licensing model to pay-per-use... The question is: What happens if, for any reason, there's not enough budget to accept this model? That could be a great problem."

"It has consistently offered highly appealing academic pricing, with distinct rates for higher education and general educational purposes."

"365 Defender is billed per account. I don't know the exact price, but my supervisor told me that Microsoft Defender is cheaper than the alternatives. It's bundled, so you get all the features in one place."

More Microsoft Defender XDR pricing and cost advice

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

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

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

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

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

"The solution offers value for money."

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