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.

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.

Has supported consistent deployment across departments but needs better OS compatibility and detection performance
I am not really looking for a new solution, actually, I was preparing for an interview and wanted to have a comparison between both tools. I have not worked with any of these products before, but we had a training demonstration yesterday with Dynatrace, and I have investigated the Wiz solution better. In terms of experience, it will be my first time with CDR. I am working with something for EDR, specifically, we have an EDR, it's VMware Carbon Black Cloud. They have a hybrid environment, both on-prem and cloud. I would usually recommend this product for big companies, because it's not cheap, so only big companies would I expect to pay for that. The review rating for VMware Carbon Black Cloud is 6 out of 10.

Quotes from Members

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

Pros

"Monitoring is most valuable."
"The policy configuration is great, the granularity of policies that are available is very helpful, it is straightforward to set up, and it has pretty much everything we need and works well within the Palo Alto ecosystem."
"The solution is a new generation XDR that has a lot of artificial intelligence modules."
"They did what they said, and this solution could apply to any scenario."
"The behavior-based detection feature is valuable."
"Cortex XDR by Palo Alto Networks has changed the way my security team detects, investigates, and responds to threats, as we are able to see the files, unwanted files, unsecured files, and unauthorized files, so we are quarantining them."
"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."
"We can use Cortex XDR to get the entire graph of the incidents from source to destination, and we can take remedial action."
"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."
"For setup, the server can be given to you as a VM image and with minimal configuration needed."
"They're highly stable in comparison with other solutions I have."
"Probably the most valuable feature of CB Response is its ability to isolate a host and take it off the network, so it's not spreading anything. We have two security operations centers around the globe. When an SOC analyst sees something on an endpoint, they can use Carbon Black Response to isolate that host from the customer's environment and prevent any kind of lateral spread."
"The most valuable feature of VMware Carbon Black Cloud is the possibility of securing any PC worldwide."
"We use it for platform metrics, for all use cases."
"The market information they gather from the community is really good. Their configuration capabilities are good."
"With this product in our hands, we are able to remotely isolate exploited endpoints in seconds and perform a live deep dive of any endpoint into its running processes (as necessary) without the need for extra scripts."
"The most valuable feature is its ability to seek out abnormal activity and to create alerts."
 

Cons

"In an upcoming release, the solution could improve by proving hard disk encryption. If it could support this it would be a complete solution."
"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."
"Cortex XDR by Palo Alto Networks could improve by adding a sandbox feature to better compete with their competitors which have it."
"The configuration could be simplified. I would like to see better protection, specifically to protect email applications."
"The GUI could be improved. It's a little bit cumbersome. It could be more user-friendly."
"We had a problem with getting our older endpoints up to date, but their newest updates have been really good. I've been pleased with it in terms of what our needs are. It's doing what we want it to do."
"Being able to filter the events to see those that are related to the actual alert would save time spent by the engineer."
"Technology evolves every day, so it would be nice if it gets more secure. It can also have more integration with other platforms."
"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."
"It's not highly available, so you have to have a core server."
"There have been some performance issues when deploying on Windows Server, but I believe Carbon Black is working on that."
"The threat intelligence feed could use some fine tweaking."
"The dashboard should be more user-friendly."
"Training and education for both partner and customer, including product marketing need to be improved."
"If Carbon Black could improve in the area or reducing the number of false positives or if there was a better way to filter out false positives that would enhance efficiency and utility."
"It's not highly available, so you have to have a core server. If the primary server goes down, you need a new one. It's not available at the same time, however. It's not automatically swapped from one server to another."
"Setup is incredibly complex and poorly documented. Every time an upgrade was needed we would need to engage Professional Services for troubleshooting help. Certificates and web services proved to be the most significant sticking points. Since the product runs on a Linux platform, perhaps having staff with more Linux experience could have alleviated some difficulty."
 

Pricing and Cost Advice

"It is cost-effective compared to similar solutions. It fits for the small businesses through to the big businesses."
"The price was fine."
"Its pricing is kind of in line with its competitors and everybody else out there."
"The solution is expensive. It's pricing is on a yearly-basis."
"The solution has one subscription for endpoint protection and one subscription for detection and response. The two licenses combined give you the BRO version."
"When we first bought it, it was a bit expensive, but it was worth it. The licensing was straightforward."
"It is "expensive" and flexible."
"This is an expensive solution."
"It’s a single license platform."
"VMware Carbon Black Cloud is an expensive solution."
"Pricing for this solution could be made lower."
"Purchase Professional Services up front as part of the implementation package, then renew hours annually to ensure you have adequate support for upgrades and enhancements. Overbuy by at least 10% to account for infrastructure growth."
"The solution is very inexpensive so there is great cost savings to using it."
"You need to pay for the licensing of the product. The pricing is costly."
"We had no issues purchasing through our preferred reseller and were able to get a fair price even when not purchasing direct. Carbon Black Enterprise Response didn’t break the bank, though adding on the matching antivirus and anti-malware components of the Protect product was more than we could afford, even with some discounting. Cb Response is really designed to complement Carbon Black’s Defense product. While Response can be used on its own, coupling with Defense seems like the best strategy if you can afford the price tag."
