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.

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

"We've had a significant increase in blocking with a decrease in false positives, because it's looking at how the files work, not just a list of files that it's been told to look for."
"We can use Cortex XDR to get the entire graph of the incidents from source to destination, and we can take remedial action."
"Stability is one of the features we like the most."
"The solution's stability is generally good."
"The anti-exploit is impenetrable."
"The user interface of the solution is sophisticated and straightforward."
"It integrates well into the environment."
"The stability is pretty good except for one or two cases, and based on the performance, it's been okay with pretty high performance, no bugs or glitches, and it doesn't crash or freeze."
"It is easy to use because it is already pre-installed in Windows 10. We don't have to do anything to configure it. You can also configure the firewall by using a group policy so that it can be easily adopted in an environment."
"I have been using it for a while, and I have never had any virus infection, data leak, or other security breaches."
"There are several features that have helped to improve our security posture at the prevention level, such as the attack surface reduction controls and the exploit prevention control."
"What I found most valuable in Microsoft Defender for Endpoint is that it's out-of-the-box, which brings more value to the customer."
"The intelligence mechanisms are good."
"It is easy to install and use requiring little maintenance but applying updates."
"For companies that are Microsoft shops, I would recommend the product."
"Defender is an antivirus program available at a lower price than other products, like Symantec, McAfee, etc."
"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

"It takes time to scan the servers and devices."
"It is not a suitable solution if you are looking for a single product with multiple features such as DLP, encryption, rollback, etc."
"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 solution should force customers to integrate with network traffic to see the full benefits of XDR."
"Cortex XDR by Palo Alto Networks could improve by offering remote management. It would be useful to look at the client's issue to fix it."
"Cortex XDR by Palo Alto Networks can improve mobile integration to allow access to the console."
"Cortex XDR by Palo Alto Networks could improve by offering remote management."
"The tool needs to be improved in terms of integration and interface."
"The solution could be even more secure and provide an even higher level of security."
"Defender’s GUI can be optimized. The console needs to be more refined."
"Initially, I experienced performance issues that hampered our servers. However, after setting appropriate exclusions, everything seemed to work fine."
"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."
"When compared with other vendors, the pricing is very high."
"The scalability could be improved - I would rate it between a seven and an eight."
"There is room to improve the security of the solution."
"It can be more secure."
"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

"Every customer has to pay for a license because it doesn't work with what you get from a managed services provider."
"If one wishes to work with another team or large number of users at a future point, he must purchase a license for them."
"Its pricing is kind of in line with its competitors and everybody else out there."
"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."
"Cortex XDR is a costly solution."
"Cortex XDR by Palo Alto Networks is quite an expensive solution."
"I don't recall what the cost was, but it wasn't really that expensive."
"The cost depends on your chosen license type, like Pro or other licenses."
"I'm not too familiar with costs as I'm an architect, though I know about online pricing, as I help two teams with online purchasing and procurement. Nowadays, everyone has an enterprise agreement, such as an E3 license, which we provide to our customers."
"The normal, standalone model, is not expensive, but the enterprise model that includes the bundle with email and some web protection, is a bit more expensive."
"We have seen ROI. Most of the other competing alternatives will cost up to around $30 per user device. We average 400 devices. Therefore, the amount that we save each year is 400 times $30."
"The cost is high for E5 licenses, but if we go with the E3 license, most of the features are not covered."
"It is free."
"This product is included in the pricing for Windows."
"Microsoft Defender for Endpoint is cost-effective because there's one unified license, and with this unified license, you get the capabilities for your cloud applications, servers, and endpoints as well. Therefore, it saves us a lot of money because the cost with other solutions is for just one piece of OS or maybe an urban environment. The licensing process is not complex as well."
"This solution is part of an enterprise license we have."
"It’s a single license platform."
