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.

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.

Correlates incidents, allows for quicker identification and helps prioritize investigations

The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

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."

"The multi-layered approach to the product gives you confidence that it will stop exploits, ransomware, worms, or viruses from compromising endpoints, essentially providing peace of mind."

"Threat identification and detection are the most valuable features of this solution."

"The product's most valuable features are massive user and feature intelligence exploit detection."

"The solution allows us to make investigations. Other XDR solutions also provide similar capabilities but for investigation, Cortex XDR is better."

"I don't have to do much monitoring with it; I don't have to have anybody manually looking at this, it gives us reports, and it lets us know if something needs to be addressed, and we can easily address it."

"Stability is one of the features we like the most."

"Monitoring is most valuable."

More Cortex XDR by Palo Alto Networks pros

"The support provides a 24 hrs service which I am completely satisfied with."

"A crucial aspect for our team is the inclusion of identity and access management tools from the vendor."

"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."

"The most valuable features are machine learning, AI, and auto-remediation of none malicious alerts."

"I rate Microsoft Defender XDR 10 out of 10."

"Many people don't realize that Microsoft Azure, Exchange Online, and the security and compliance portal all sync together. For instance, within the Azure portal you can set security restrictions and policies to help secure your tenants... The good part of it is that these products have already been integrated. When you sign on as an admin you have global admin rights and that gives you access to all these features."

"Microsoft Defender XDR provides strong identity protection with comprehensive insights into risky user behavior and potential indicators of compromise."

"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

"It can integrate with almost any cybersecurity tool available in the market."

"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."

Cons

"There are some false positives. What our guys would have liked is that it would have been easier to manipulate as soon as they found a false positive that they knew was a false positive. How to do so was not obvious. Some people complained about it. The interface, the ESM, is not user-friendly."

"It takes time to scan the servers and devices."

"Every 30 or 40 days, there's a new version and we need to go and make sure our customer's laptops are upgraded."

"Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth."

"The solution lacks real-time, on-demand antivirus."

"Cortex XDR could improve its sales support team, including better commission structures and referral programs."

"The installation should be easier and the Palo Alto pre-sales and sales teams should have more information on the product because they don't know what they are selling."

"The setup is quite easy. We had appropriate support from the manager. One thing that was missing was the integration part."

More Cortex XDR by Palo Alto Networks cons

"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."

"Some of our older hardware experienced a slight bump in CPU and memory usage. Although I don't have empirical data to back that up, I would suggest possibly more streamlining in the software."

"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."

"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."

"When discussing the secure score, which includes overviews and recommended actions, some of these recommended actions are not applicable to us, particularly those related to Microsoft Internet Explorer, which we do not use in any of our environments."

"The dashboards could be improved."

"The data recovery and backup could be improved."

"The documentation on their website is somewhat outdated and doesn't show properly. I wanted to try a query in Microsoft Defender 365. When I opened the related documentation from the security blog on the Microsoft website, the figures were not showing. It was difficult to understand the article without having the figures. The figures were there in the article, but they were not getting loaded, which made the article obsolete."

More Microsoft Defender XDR cons

"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."

"Support is an issue because they have a limited number of resources."

Pricing and Cost Advice

"I don't have any issues with the pricing. We are satisfied with the price."

"We pay about $50,000 USD per year for a bundle that includes Cortex XDR."

"Licensing for Palo Alto Networks Cortex XDR can be costly, especially when it comes to a hundred users. A license is required for each user, and the subscription must be renewed on a yearly basis."

"I am using the Community edition."

"The pricing is a little bit on the expensive side."

"Cortex XDR by Palo Alto Networks is an expensive solution."

"It has reasonable pricing for the use cases it provides to the company."

"This is an expensive solution."

More Cortex XDR by Palo Alto Networks pricing and cost advice

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

"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."

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

"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."

"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."

"With the little idea I have about the costs, I can say that XDR tools tend to be a bit expensive. If you are using Microsoft Defender XDR, then you need to go for a subscription-based pricing model."

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

"Sometimes 365 Defender is expensive, but it can be moderate, depending on the organization's size and the license type. We're satisfied with the cost because it gives us a product that protects our entire environment with DLP. To compromise some cost, of course, we are to complete the most secure environment."
