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.

A competitive choice for network detection and response with exceptional user interface, ease of implementation and minimal false positives
The NDR feature analyzes network traffic, creating records with connection details. While these records offer insights, there's a limitation in investigating payloads directly. ExtraHop provides an option for an additional server to save payloads, but its temporary storage has constraints. Unlike some competitors, it lacks an automatic payload-saving feature for each detection, presenting an improvement opportunity. Suggested enhancement involves the main sensor prompting payload storage for specific detections, streamlining the investigation process, and contributing to a more efficient workflow. A drawback includes packet storage limitations for payload data, necessitating timely extraction for thorough investigations.

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 have found in our test Cortex XDR by Palo Alto Networks to be a very good tool."
"We can visualize and control the activities in the environment from anywhere."
"It's very stable. I've never experienced downtime for the ASM console or ASM core."
"Their XDR agent and their behavioral indicators of compromise (BIOC) are pretty nice. Their managed threat hunting is also pretty nice. They also have WildFire, which is a service for actively looking for malware. It's quite useful."
"WildFire AI is the best option for this product."
"Monitoring is most valuable."
"It blocks malicious files. It prevents attacks. It doesn't require many updates, it's a very light application."
"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."
"It is very easy to collect and handle data in ExtraHop Reveal(X) Cloud. Integration with Big Data is also easy. Many of our customers integrate it with Big Data platforms like Splunk or Elastic. It is also easy to handle and easy to understand."
"It is scalable."
"It stands out for its intuitive and efficient user interface, robust detection capabilities with minimal false positives, and the ability to handle encrypted traffic, making it a valuable asset for network security and management."
"Their technical support is more effective and of better quality than other competitors."
"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

"Currently, if you use Palo Alto endpoint protection as the only solution it's very complicated to remove pre-existing threats."
"The technical support is not very good. I find the process difficult."
"Cortex XDR by Palo Alto Networks could improve by offering remote management."
"To jump from the partner to Palo Alto directly was challenging."
"It would be good to have a better way to search for a file within the UI."
"There are some false positives."
"It is not easy to sell Cortex XDR, not because it isn't a good tool."
"I don't like that they have different types of licenses. For example, if users select a license, they think they will have all the platforms they need to improve their network or security. But after some time, Palo Alto Networks changed their licensing, and some of the features that, for example, were free at the beginning now have a cost. I think the integration can be improved. For example, a lot of tools are just integrated through APIs."
"They can include integration with SAP. Currently, no vendor provides network performance monitoring in the SAP market. It is a very big market. We have around 400 customers for SAP in Korea. In the USA, there are more than 10,000 customers."
"There needs to be more support."
"A drawback includes bucket storage limitations for payload data, necessitating timely extraction for thorough investigations."
"Their professional service can be improved."
"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

"Our license will require renewal in August, after which the maintenance will continue as usual."
"We didn't have to pay any additional fee for the cloud instance. It just came with the renewal, which was nice."
"The pricing is a little high. It is per user per year."
"This is an expensive solution."
"The pricing is okay, although direct support can be expensive."
"I am using the Community edition."
"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."
"Our customers have expressed that the price is high."
"When compared to other solutions, it aligns with the market average, indicating a competitive pricing level."
"It’s a single license platform."
