Gained full visibility and streamlined threat detection through behavior-based insights and AI integration
Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth. We have fine-tuned our security policies and allowed different levels of policies to get rid of those false positives. Currently, we are getting a fairly good amount of incidents that are not false positives or benign, but actionable items. The process is streamlined. In the initial days, the operations used to get involved in a lot of benign and other activities, but now the process is streamlined. We are leveraging the auto-detection and remediation plans. The operations teams are now more involved in other business roles as well, not just looking into the logs and fetching out what's happening there. They have fixed a lot of things. Initially, they didn't have IAC code drift detection, cloud posture management, or security posture management, but they have those now. They purchased different vendors and did a merger with that. They have now Prisma Cloud that gets integrated and now they are working with Cortex Cloud. Everything that was negative has now been addressed, and the product altogether looks to be in a very better and mature shape now. Currently, it's more or less detecting the workloads with AI-based best practices. Since most organizations are consuming AI agents and other things, we are looking forward to seeing what other feature enhancements Palo Alto can support in that.

Integrated defenses have unified threat hunting, phishing simulations, and identity investigations
I appreciate Microsoft Defender XDR's MDE, Microsoft Defender tool, which has Attack Simulator. Instead of doing a phishing campaign and getting a separate tool, Microsoft Defender XDR does it all. These features of Microsoft Defender XDR have helped us conduct a phishing campaign quarterly, which has been beneficial. I also appreciate the fact that it has Defender for Office integrated, Defender for Identity, and everything integrated together. I would describe the process of using Microsoft Defender XDR to prioritize incidents in my security operations as quite decent. I appreciate the automatic alerting system where any incidents or alerts we receive come directly to our email. From there, we can open the email, go directly to Microsoft Defender XDR, and start our investigations and remediations. I perceive the integration of security and identity access management in Microsoft Defender XDR as affecting my identity protection strategies very well because it is well integrated with Purview, integrated well with Entra ID, and integrated well with Exchange. I especially appreciate MDO, the Office product. If anything happens and I want to conduct an investigation, it takes me directly to Exchange, where I can also investigate any emails or phishing incidents. Instead of going to different portals, everything can be done from Microsoft Defender XDR. If necessary for further investigation, Microsoft Defender XDR then directs me to that environment. I would assess the integration of AI in guiding security actions within Microsoft Defender XDR as quite positive. Recently, Security Copilot went big, and it is beneficial that I can use that, especially to write KQL. I can do threat hunting features and intelligence all within using Microsoft's Security Copilot. It also has a nice AI feature for threat hunting. I know that all the Defender logs go to Sentinel, and I can pull it up from Microsoft Defender XDR or from Sentinel. The fact that I can actually do all that within Microsoft Defender XDR is a nice feature. In the top module, I can do threat lookups, and I can actually type KQLs in Microsoft Defender XDR and look up incidents. Predictive shielding has had a nice impact on my proactive security measures. It is beneficial that it has, similar to Entra ID, a secure score. For me to improve the product, the secure score helps me out. If I rate it from highest to lowest, I can see what things I can improve. Secure score helps me see what areas I can improve in Microsoft Defender XDR to increase my score and bring it to 80 or more. Knowing Microsoft Defender XDR from using it since 2019, before COVID days, I know that they have improved significantly. It is much more user-friendly and has a very nice vulnerability feature that I find handy and useful. The fact that this feature integrates into Intune is also very decent.

A scalable and stable solution with straightforward deployment
We can generate maps from the environment. For example, suppose there is a virus that has a zero-day attack and is publicly unknown. We can block that and keep it away from the network so it is not further replicated. It also has custom white and black lists. We can add a good reputation on both lists and use the sonar technology for Symantec and the online network for advanced reports.

Quotes from Members

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

Pros

"But overall, when we speak about security and protection, they are one of the top providers."
"Stability is one of the features we like the most."
"Cortex XDR by Palo Alto Networks is easy to use and does not consume a lot of hardware resources."
"They have a new GUI which is just fantastic."
"We can use Cortex XDR to get the entire graph of the incidents from source to destination, and we can take remedial action."
"The most valuable feature is that you can select remote access of any machine for sandboxing."
"They did what they said, and this solution could apply to any scenario."
"My advice for anybody who is considering Cortex XDR is that it is a complete solution, and has very good features."
"The ability to integrate and observe a more cohesive narrative across the products is crucial."
"Defender XDR has a feature called the timeline that lets you track all activities. It helps a lot with investigations."
"The EDR features are valuable. By getting the EDR features, we have more control over the device. We have information about events in real-time and more protection against zero-day threats and zero-day vulnerabilities. We can monitor every event or action that a device is going through. We can get an idea if it is something malicious or if we have to take any actions."
"Microsoft 365 Defender is a stable solution."
"Microsoft Defender's most critical component is its CASB solution. It has many built-in policies that can improve your organization's cloud security posture. It's effective regardless of where your users are, which is critical because most users are working from home. It's cloud-based, so nothing is on-premise."
"Vulnerability assessment and just-in-time access are some valuable features of Defender for server plans."
"Defender XDR enables you to scan a system remotely and get a complete inventory of its assets. You can gather more information from the asset inventory and apply threat intelligence using Office 365 or something."
"Microsoft Defender is very stable, and you can see that there is a 99.9% success rate when they give us good service."
"We can block a virus that has a zero-day attack and is publicly unknown and keep it away from the network so it is not further replicated."
"You can advise the solution and protect your environment."
 

Cons

"The dashboard could use some significant improvement, just making it more useful with more information. It has a limited amount of information right now. It is customizable, but I'd love to see a better out-of-box dashboard."
"For Cortex XDR by Palo Alto Networks, if I had to point out improvements, I would say the UI is still somewhat difficult for beginners."
"The encryption is not up to the mark."
"If you compare it to SentinelOne, which has more functionalities and detection capabilities on an open platform, the pricing on SentinelOne is far more reasonable and cheaper than Cortex XDR by Palo Alto Networks."
"The product's pricing could be better."
"There are some default policies which sometimes affect our applications and cause them to run around. In the hotel industry, we use a different type of data versus Oracle and SQL. By default, there are some policies which stop us from running properly. Because of this, the support level is also not that strong. We have to wait to get a results."
"Additionally, I think the price is very high, and if it can be adjusted, I believe it will be a very good solution."
"It is a complex solution to implement."
"These days, in the security industry, there is a buzzword called zero trust. I personally have not seen much evidence of how Defender can enhance the story of Zero Trust for enterprises."
"365 Defender has multiple subsets, including Defender for Cloud Apps. When integrating Defender for Cloud Apps with apps on third-party cloud platforms like AWS or GCP, there are limitations on our ability to control user activities. If Microsoft added more control over third-party products, that would be a game-changer and help us quite a lot."
"There is no common area where we can manage all the policies for the EDR, third-party solutions, devices, servers, Windows, Mac, etc., but it's on the road map, and we ware waiting for that feature."
"The design of the user interface could use some work. Sometimes it's hard to find the exact information you need."
"Microsoft Defender XDR can be improved as a solution because it's still quite costly; it's part of E5, E5 security, so the cost is still quite high, especially considering SME and C customers, or SMB customers."
"Microsoft frequently changes the names of its products, sometimes even renaming entire portals or features."
"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."
"Since all of our databases are updated and located in the cloud, I would like additional support for this."
"The solution should have better reporting."
 

Pricing and Cost Advice

"Very costly product."
"The pricing is a little high. It is per user per year."
"It's the most expensive solution, but features-wise, it's quite strong. It's very good for protection, so the results are very good in the case of protection. I would rate it a two out of ten in terms of pricing."
"It is present, but when compared to other competitive products, I would say it is not less expensive; however, when all of the other added values are considered, the price is reasonable."
"When we first bought it, it was a bit expensive, but it was worth it. The licensing was straightforward."
"We didn't have to pay any additional fee for the cloud instance. It just came with the renewal, which was nice."
"Compared to CrowdStrike, Cortex XDR is an expensive solution."
"It has a yearly renewal."
"On average, we pay around 55 euros per user for the services and features we receive."
"The product is fairly priced for what we get from it."
"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."
"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."
"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."
"We have a lot of problems in Latin America regarding the price of Microsoft 365 Defender, because the relationship between dollars and the money of the different countries, it's is a lot. Many customers that have small businesses say that they would like the solution but it is too expensive. However, large companies do not find the cost an issue."
"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."
