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.

Automatically isolates threats and integrates with logging to reduce response time

Overall, I would evaluate the Microsoft support level that I receive at probably about a seven, but that depends on the day. It has been spotty. We have had issues where the urgency level of the Microsoft support is not as high as ours, especially during a data breach or potential data breach situation. We have had issues with some of the offshore support being lackluster. One specific thing that comes to mind is we were on a support call with our CISO on the call, and the Microsoft agent, who did not actually work for Microsoft, is one of the vendors that Microsoft uses for support, said, "Just to set expectations, my lunch break is in an hour and I am going to go away then." For us, it was already ten o'clock at night and we had been working on this for a couple of hours, trying to get a security engineer on with us. For him to tell us that he was going to go away and have lunch, it was, "Okay, but go find somebody else if you need to." It was just the lackluster approach, and it seemed like he did not really care. We seem to get a lot of this when we get non-Microsoft support. I can identify areas for improvement with Microsoft Defender for Endpoint, as it is kind of a convoluted mess to try to take care of false positives. Especially when they have been identified as false positives but they keep going off over and over again. It is great for my pocketbook because it generates a lot of on-call action, but I would really prefer more sleep at two o'clock in the morning than dealing with false positives. I would say that the unified portal for managing Microsoft Defender for Endpoint is suitable for both teams as they are all in there. It would be great if they would stop moving things around and renaming things, which makes sense. The new XDR portal is pretty nice. Being able to have it central again inside of the regular Security Center without having to open up two windows is helpful. Overall, I think it is pretty good. There is always going to be something that could be improved, such as alerting and the ability to modify alerts would be a little bit helpful to have. Being able to add more data into the alerts and turn off alerts that are not as useful would be beneficial. It is hard to say what the quantitative impact the security exposure management feature has had on our company's security, because a lot of it is kind of subjective. I think we are sitting at around a fifty percent score still, and a lot of it is just kind of unusual circumstances that we cannot really implement without breaking the organization.

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

"Cortex XDR is a very capable solution for protecting large networks and a lot of endpoints. It's very useful because the automation is very high, and if you combine it with the features on Palo Alto firewalls, it provides very strong protection."

"The user interface of the solution is sophisticated and straightforward."

"From a single pane of glass, you can easily manage all of your endpoints."

"Stability is a primary factor, and then there's the ease of distribution and policy management; Cortex XDR by Palo Alto Networks is very easy to work with, and we're quite happy with them."

"The tool is easy to use."

"I generally believe that Cortex XDR by Palo Alto Networks is probably the best in the market right now."

"The product's initial setup phase is very easy."

"The stability of the solution is very good. We have about 100 users on it right now, and we use it twice a week."

More Cortex XDR by Palo Alto Networks pros

"The best thing I like about it is its interaction with the other Defender products. It provides the ability to push telemetry up. It gives me endpoint visibility and allows me to take automated actions."

"It has Kusto Query Language (KQL), so we can use our own queries to find anything."

"The most valuable feature is that we can use the solution right out of the box without too much configuration."

"Integration between Microsoft products is very easy."

"Microsoft Defender for Endpoint has helped free up my SOC team to work on other projects and tasks, and the automated reporting and dashboarding has saved them a lot of time, amounting to several man-hours."

"We have just started to implement it. It is useful for protection from malware and ransomware."

"Its real-time security is the most valuable."

"DFE organizational security posture has been a positive experience. We're a Microsoft house. It works. Once it's deployed and once it's configured, it works and our clients tend to be happy with it. I haven't really experienced anyone who has been so unsatisfied with the platform that they wanted to go a couple of different directions, that has never happened to me."

More Microsoft Defender for Endpoint pros

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

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

Cons

"While using Cortex, I noticed some aspects that could be improved, such as increasing the synchronization speed between XDR and Xnor."

"There is a severe gap in functionality between Windows, Linux, and Mac versions."

"Managing the product should be easier."

"In reporting they should have a customizable dashboard due to the fact that C-level people don't like reporting to the IT department. They prefer to have a real-time dashboard. That kind of dashboard needs to have various customizations."

"Cortex XDR by Palo Alto Networks is a very good product, but financially, it is very expensive, so the company should look into that area."

"I would like to see them include NDR (Network Detection Response). Then it would work well with SIEM Response."

"I would like to see improvement in the tool's user interface, particularly in the area of managing alerts and providing more reporting capabilities."

"The MAC agent is not as robust feature-wise as the PC version."

More Cortex XDR by Palo Alto Networks cons

"With increase of cyber threats and cybersecurity issues, I would recommend that the product be developed like an AI product with more features which can counter any threat in the coming eras."

"I would like to see fewer pop messages and alerts."

"Some integration components for Mac should be added. We use both Windows 10 desktops and Mac desktops, but presently, the Mac component is still lagging a bit behind."

"My main issue with the tool is that there are too many menus. This causes a steep learning curve for those without training or unfamiliar with Defender for Endpoint. From an end-user perspective, the solution is there on the machine and does its job; it works seamlessly. However, as a security professional dealing with it behind the scenes, the learning curve can be steep, but not too steep. Still, it has taken some of my analysts up to a month to get familiar with the product."

"Lacks some additional integration."

"The dashboard customization could be improved."

"I would like the solution to be able to prevent unauthorized programs from installing and to block unauthorised URLs which is similar to web filtering product."

"The log searches for Microsoft Defender for Endpoint are pretty difficult to navigate. It needs a better UI or more intuitive search and filter mechanisms to make it easy to get through and filter through all the data logs."

More Microsoft Defender for Endpoint cons

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

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

Pricing and Cost Advice

"Every customer has to pay for a license because it doesn't work with what you get from a managed services provider."

"It is cost-effective compared to similar solutions. It fits for the small businesses through to the big businesses."

"Its pricing is kind of in line with its competitors and everybody else out there."

"I feel it is fairly priced."

"The price is on the higher side, but it's okay."

"It has a higher cost than other solutions, like CrowdStrike or Microsoft’s EDR tools, but it reduces the cost of our operations because it’s a new generation antivirus tool."

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

"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."

More Cortex XDR by Palo Alto Networks pricing and cost advice

"The cost is high, compared to other products in the market, if you look at it as a separate product. If you look at the cost where it is part of a bundle, the cost is okay."

"The product is free of charge and comes integrated into Windows."

"The solution comes as part of Microsoft Windows."

"The licensing costs for Microsoft Defender for Endpoint are reasonable."

"Because Microsoft Defender comes as an add-on, it can be a bit expensive if you're trying to buying it separately. Another option is to upgrade, but the enterprise licenses for Microsoft can also be quite a bit pricey. Overall, the cost of Microsoft Defender compared to that of other endpoint detection solutions is slightly higher."

"Licenses depend upon what you are looking for and what kind of security do you want to implement. There are costs in addition to the standard licensing fees. When we used to buy Symantec, we used to spend on 100 licenses. We used to spend approximately $2,700 for those many licenses, and they came in packs. To add one more license, I had to buy a pack with a minimum of 10 licenses. I had to spend on nine extra licenses because I can't get a single license, whereas when we go for Microsoft, we can get as many licenses as we want. If I have 100 users today, and tomorrow, I have 90 users, I can release my 10 licenses next month. With any other software vendor, you buy licenses for one year, and you have to stick with that. If today you have 100 licenses, and tomorrow, you have 50, you have already paid for one year's license. You can't go back and tell them that I don't require these 50 licenses because I have lost my 50 users, but with Microsoft Defender, licensing is on a monthly basis. It gives you both options. You can go yearly and save on it, or you can go monthly. You will, again, save on it. It is very fair everywhere."

"Microsoft Defender is an expensive product in my country."

"They are now doing it on an endpoint basis. It is based on the number of endpoints, which is good."
