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.

Automated security monitoring increases efficiency, but market visibility needs improvement
I am currently evaluating Stellar Cyber Open XDR in terms of their support. I do not see any major areas for improvement as of now. Their support is good, and the team is small, enabling them to cater to everyone effectively. While I have not encountered significant drawbacks so far, market penetration is challenging due to the product's newness, despite its flexibility and customization features. I find their user interface to be quite good.

Quotes from Members

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

Pros

"The level of security I get for my endpoints and servers is extremely valuable."
"The most valuable features are incident creation, policy-based protection, IP whitelisting, and device encryption. These are beneficial for endpoint and server security."
"Cortex XDR lets us manage several clients from the same console, and its endpoint defense is more advanced than traditional antivirus."
"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."
"Cortex covers everything I need. It's a perfect solution. Cortex provides a different level of visibility because it's an extended EDR, allowing you to grab logs from the network and firewalls. Palo Alto invented the concept of the extended EDR or XDR."
"From the Palo Alto side, whatever they buy, they integrate that really well into their integration suite, and that makes a massive difference."
"Palo Alto is one of the tech vendors that always provides top-of-the-line products."
"My advice for anybody who is considering Cortex XDR is that it is a complete solution, and has very good features."
"The stability is great. I haven't seen any outages with Microsoft."
"Defender for Endpoint allows us automatic resolutions if a unit is compromised or if a user clicks a malicious link."
"This product is flexible, and it is very easy to get updates from the Microsoft website."
"The most important and the most relevant features of Defender for Endpoint are the malware and ransomware protection."
"It's free because it comes with Windows."
"It is stable and very easy to use."
"I've started to test it from the security point of view. There are plenty of features that are interesting, but at this time, the XDR functionality is most valuable. It is endpoint security on steroids."
"This product offers cost-effective threat protection, which integrates with Office 365 and has unified endpoint management features."
"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

"In some cases, there are too many options for me, and it is a bit too hard to find some settings which I really need to implement."
"As an improvement, I would like to see enhanced connection speeds."
"The onboarding process could be better."
"There are some false positives."
"The playbooks could be improved to include more functionalities or actions."
"It is not very strong in terms of endpoint management. It should have additional features like DLP, encryption, or advanced device control. Currently, Cortex is good in terms of the security of the endpoints, but it is not as good as other vendors in terms of the management of the endpoint."
"I think sometimes Cortex XDR agent automatically stops event capturing from the device, and then even the dashboard does not get any notifications from the agent."
"The GUI could be improved. It's a little bit cumbersome. It could be more user-friendly."
"There could be an increase in security for the solution."
"Features like device inventory continue to lack essential workstation drill-downs showing the entire device information with the least effort."
"The GUI is very complex and could be more user friendly."
"Microsoft Defender in the basic form is not very useful for managing the security environment. The free version is not capable of covering the needs of centralized management, EDR, and behavioral analysis. If you don't have the commercial version, you can't have centralized management and set up the policies and other things. Each client is a standalone installation, which is not useful for security in an enterprise model."
"Integrating this with third-party systems has some complexity involved."
"Microsoft should improve support for third-party platforms, because not all functionality is available for all of them. It's a good product, but they should just extend the functionality for all platforms."
"Microsoft Defender for Endpoint could improve by adding more security features."
"Defender's cloud integration could be improved."
"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."
"The price is on the higher side, but it's okay."
"Our customers have expressed that the price is high."
"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."
"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."
"We pay about $50,000 USD per year for a bundle that includes Cortex XDR."
"It is cost-effective compared to similar solutions. It fits for the small businesses through to the big businesses."
"Cortex XDR by Palo Alto Networks is quite an expensive solution."
"Most people don't realize M365/E5 licenses are an amazing deal. They think "Oh, it's expensive," and I'll ask, "Compared to what?" If you don't have it you will have to buy licenses for multiple products to fill the same security space that you would have gotten with the Microsoft product. Go figure out how much it costs you per product, per user, and then come back and tell me how things add up financially."
"Pricing can always be lower."
"There is not a license required for this particular solution."
"Licensing options vary. Some customers buy it as an enterprise agreement and pay yearly. Others buy it as a CSP, so they pay per month. It completely depends on the customer's needs."
"The licensing fee is a function of your Office 365 license. The feature set you get is a function of the license as well. There is probably an E2 version, an E3 version, and an E5 version. There are several versions, and not all features are the same. So, you might want to check what features you're expecting because you might get shocked. If you only have an E3 license, the capability isn't the same."
"The product is free of charge and comes integrated into Windows."
"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."
"The solution is free and comes with Windows."
"It’s a single license platform."
