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.

Delivers efficiency and agility with USB control limitations

One area where we lag is that, since we use everything from Heimdal, including XDR and other features, we also use the privilege manager feature called Elevation. What we lack is granular USB control. We have an issue where we can only switch USB on or off. I want to whitelist specific devices in the network, which I currently cannot do.

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

"The tool's use cases are relevant to security."

"It has absolutely improved the way our organization functions, we are more secure, it is giving us more peace of mind, and it has found malicious activity happening on our endpoints that probably would not have been detected if we didn't have it."

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

"WildFire AI is the best option for this product."

"The dashboard is customizable."

"My advice for anybody who is considering Cortex XDR is that it is a complete solution, and has very good features."

"The live terminal is probably the best thing ever. It gives you the access to get straight onto any machine."

"After deploying Traps, we saw the performance of the network improve by 65 to 70 percent."

More Cortex XDR by Palo Alto Networks pros

"Heimdal is a very agile and lightweight solution."

"As compared to multiple solutions I have used in the past, Heimdal is a very agile and lightweight solution."

"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

"Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth."

"Cortex XDR could improve its sales support team, including better commission structures and referral programs."

"It is not a suitable solution if you are looking for a single product with multiple features such as DLP, encryption, rollback, etc."

"This product has not improved my organization - in fact, we are in the process of moving back to another product as a result of Cortex's horrible impact on system performance."

"It should support more mobile operating systems. That is one of the cons of their infrastructure right now."

"Data privacy is a matter of concern. You have to be careful with data privacy, it can be sensitive and Cortex can have most of your access."

"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."

"If Palo Alto reduces the pricing slightly for their products, it would make them more scalable in markets such as India and globally for cybersecurity."

More Cortex XDR by Palo Alto Networks cons

"What we lack is granular USB control."

"What we lack is granular USB control. We have an issue where we can only switch USB on or off."

"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

"I am using the Community edition."

"It is "expensive" and flexible."

"The cost of Cortex XDR by Palo Alto Networks is $55 to $90 USD per endpoint per month."

"The price of the product is not very economical."

"Cortex XDR by Palo Alto Networks is an expensive solution."

"Cortex XDR's pricing is ok."

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

"I did PoCs on products called Cylance and CrowdStrike. Although, I consider these products and they were also good, when it come to cost and budgetary factors, Traps has been proven to be better than the other two products. It is quite cost-effective and delivers all the entire solution which we require."
