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.

Consistent threat hunting and anomaly detection deliver valuable insights for network security management
In terms of improvement for Darktrace, pricing is the main concern. Pricing bothers me and this is one of the major factors when choosing a solution. When we get feedback from customers, that's the only felt need. When we factor in Darktrace, we do it only limited. We put it on where the perimeters and connections are, but still, some gray areas are left out, especially if we have multiple branches. We need Darktrace on each branch to get the data out, and I suggest having some kind of a centralized product that gets data from multiple sources to aggregate and provide the data.

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

"On a scale from one to ten, I would rate Cortex XDR by Palo Alto Networks a nine."
"Its interface and pricing are most valuable, and it is better than other vendors in terms of security."
"The user interface of the solution is sophisticated and straightforward."
"We use Cortex XDR by Palo Alto Networks for its ability to detect based on behavior rather than simple virus scan to prevent malicious activities."
"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."
"The solution's most valuable feature is the user interface."
"They did what they said. This solution could apply to any scenario."
"One thing that I like about Cortex XDR is its ability to detect all the suspicious or malicious binaries, and it can integrate with Palo Alto Firewall."
"Darktrace's most valuable features are that it understands the network environment and is able to trace the traffic and alert on anomalies."
"The most valuable feature is that it gives us visibility of rogue traffic that is on the network."
"This solution is both scalable and stable."
"Darktrace is very flexible."
"It provides a comprehensive, detailed view of network activity and whatever is happening inside it."
"One member of staff is enough for deployment and maintenance because Darkforce is AI-driven; it does a lot of things by itself."
"The most valuable part of the product is the whole package, as the features included in the Enterprise Immune System are complete and effective and its detection engine is ridiculously good."
"While it is complex, and difficult to use, once you understand the correct way to use it, it's a very good platform."
"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

"There are some limitations on the Traps agents."
"There are some default policies which sometimes affect our applications and cause them to run around. In the hotel industry, we use a different type of data versus Oracle and SQL. By default, there are some policies which stop us from running properly. Because of this, the support level is also not that strong. We have to wait to get a results."
"Additionally, I think the price is very high, and if it can be adjusted, I believe it will be a very good solution."
"As an improvement, I would like to see enhanced connection speeds."
"Cortex XDR by Palo Alto Networks is a very good product, but financially, it is very expensive, so the company should look into that area."
"It is not a suitable solution if you are looking for a single product with multiple features such as DLP, encryption, rollback, etc."
"Every 30 or 40 days, there's a new version and we need to go and make sure our customer's laptops are upgraded."
"The downside to the solution is that there are a large number of false positives."
"The solution could be easier to use."
"In an upcoming release, there could be more customizable playbooks or a library of playbooks to choose from."
"It can have more integration with orchestration or event management solutions. They can provide more knowledge or research information for analysts for investigating cases and detecting anomalies in networks."
"The cost of the solution is expensive for smaller businesses."
"This product needs more in terms of prevention. The detection capabilities work well but once a threat has been detected, Darktrace should work to prevent it from doing anything malicious."
"We want to continue using Darktrace but it's very expensive."
"Darkforce could be improved in the range of the interface; how to interact with the actions it's taking or not taking."
"I did not use the AI features because they should make it more user-friendly which would be a benefit."
"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

"It is present, but when compared to other competitive products, I would say it is not less expensive; however, when all of the other added values are considered, the price is reasonable."
"It is cost-effective compared to similar solutions. It fits for the small businesses through to the big businesses."
"In terms of the cost Cortex XDR by Palo Alto Networks is very expensive because we are a Mexican company and when you translate dollars to pesos the cost is very high. The solution is very expensive for Mexican companies. I understand that they have international prices, but I do not think it offsets the price enough for many companies in countries, such as Mexico. The amount it is reduced is not a massive percentage."
"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."
"I don't recall what the cost was, but it wasn't really that expensive."
"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."
"I feel it is fairly priced."
"The pricing is a little high. It is per user per year."
"It is expensive."
"The tool's pricing is costly."
"Darktrace is quite an expensive solution."
"Our customers feel that the price of Darktrace is quite high compared to other solutions."
"The price of the solution is not cheap. It is not a one-time purchase, there is a subscription that needs to be paid every one to five years depending on your choice. It is expensive but you can reduce the price by only using the services that you want."
"The pricing is subscription-based and it is high."
"There is an annual license to use Darktrace."
"Darktrace is pricey, but the price is reasonable for what the solution does, and it's comparable to other products."
"It’s a single license platform."
