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

"Cortex XDR by Palo Alto Networks is easy to use and does not consume a lot of hardware resources."
"The most valuable feature is that you can select remote access of any machine for sandboxing."
"The level of security I get for my endpoints and servers is extremely valuable."
"The one feature of Palo Alto Networks Traps that our organization finds most valuable is the App ID service."
"Palo Alto is the best security solution in the market."
"The initial setup is easy."
"We have found in our test Cortex XDR by Palo Alto Networks to be a very good tool."
"The main benefit of using Cortex XDR by Palo Alto Networks while employing Palo Alto Firewall at the internet edge is that it improves security on our endpoint devices, integrating seamlessly with Palo Alto Firewalls to deliver comprehensive network, analyst, and security details all in a single dashboard, which allows us to manage everything from our network devices."
"Web filtering is the most valuable feature of Microsoft Defender for Endpoint because it effectively maintains security for website access."
"When it comes to technical support, I have found Microsoft to be outstanding."
"Integration between Microsoft products is very easy."
"It's a very complete application. I have all the controls in one site. I can track emails, attacks, and threats, and I can research information. I really like this configuration because I have all the information in place."
"What the Defender platform does is that it reduces the size of the haystack, and it'll say that the needle is over here."
"This is not an inventory solution, but it helps you take count of how many workstations you have, as well as what software is installed on each of them."
"We are able to productively integrate with existing on-prem, hybrid, or cloud applications."
"Along with security, there are certain IT policies in terms of accessibility of different sites, which are there in the organization, and with everything put together, there haven't been any instances where I have seen any kind of issues such as malware or other malicious event getting through on my laptop."
"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 the next release, I would like to see more UI improvements. Their UI is a bit basic. When we are speaking about Palo Alto Networks they are the big company, so they can improve the UI a little bit. The UI, the reports, the log system can all be improved."
"When it comes to malware files, it should be a little quick because, at times, it would give a wrong result in the sense of what it might be on malware, even if it still might be a normal one."
"The technical support is not very good. I find the process difficult."
"The encryption is not up to the mark."
"It is not a suitable solution if you are looking for a single product with multiple features such as DLP, encryption, rollback, etc."
"It would be good to have a better way to search for a file within the UI."
"It is not easy to sell Cortex XDR, not because it isn't a good tool. Its marketing needs to be improved."
"The solution should add unwanted malicious hash values to a block list so that whenever the action is triggered, it will automatically prevent the malicious content."
"My main issue with the tool is that there are too many menus."
"I think the solution needs to be more on par with other antivirus products in the market."
"Sometimes, there are different skews. In a basic skew, they should have basic log analysis without the need to integrate with any third-party or SIEM solutions, like Sentinel. This would make it so much easier for users who don't have log collection or log analysis."
"Auto recovery is the most important feature that we would need from this solution. For decryption, similar to Malwarebytes, there should be something to be able to recover the data up to the last normal status. Its ability to recover data to the last normal copy must not exceed 5 to 10 minutes."
"We encountered some issues when we were trying to enable automatic updates from our group policy."
"The scanning is slow when it is working with incoming emails."
"It can be more secure."
"The scalability could be improved - I would rate it between a seven and an eight."
"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

"The pricing seems fair, and I do like the licensing model. You use wherever they are, and it is elastic."
"I don't have any issues with the pricing. We are satisfied with the price."
"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."
"Every customer has to pay for a license because it doesn't work with what you get from a managed services provider."
"Its pricing is kind of in line with its competitors and everybody else out there."
"The price was fine."
"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."
"It's way too expensive, but security is expensive. You pay for your licensing, and then you pay for someone to monitor the stuff."
"AV solutions are pretty expensive because they are necessary, not just for protection, but many businesses need them to comply with regulatory bodies and receive accreditation. We recently purchased an E5 license, which gives us access to the entire Microsoft suite. I would say the pricing is competitive; most tools of this kind are similarly priced. There are minor differences between the competitors, but they aren't spectacularly different. Defender for Endpoint makes sense because all our solutions are in the same place, paid for with a single license. The subscription price is around £50 per user per month, though it may have increased slightly."
"The licensing costs for Microsoft Defender for Endpoint are reasonable."
"We have been using the free version."
"The price of Microsoft Defender for Endpoint is reasonable. Other solutions are more expensive, such as ClowdStrike."
"Licensing models of Microsoft are renowned for being complex. We just purchased the whole E5 stack. With E5 licenses for users, we get access to a bunch of features that are not just related to security. I would rate them a three out of five in terms of pricing."
"I recently switched from education to private business, and all I can say is that private business licensing from Microsoft is not cheap until you hit certain quantities or scale. That does not mean that it is not comparable to other industries. It is similar pricing, but it is still crazy to me how much you pay for a client. I feel it is high, but it is in line with other vendors."
"If we are acquiring everything in a single place, the front end becomes cost-effective."
"The pricing is competitive."
"It’s a single license platform."
