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

"The initial setup is easy."
"Its interface and pricing are most valuable, and it is better than other vendors in terms of security."
"I can highlight that we have not faced any security incidents with Cortex XDR by Palo Alto Networks, and even though our environment is quite dynamic, we have not faced any security incident with Cortex XDR by Palo Alto Networks until now."
"The solution's most valuable feature is the user interface."
"It is easy to use."
"The most valuable feature of Cortex XDR by Palo Alto Networks is its machine-learning capabilities. Additionally, there is full integration with other solutions."
"Cortex XDR by Palo Alto Networks has helped lighten the load of our security analysts because it was the major tool that we were using and the one we utilized most."
"Cortex is the best tool for endpoint detection, and I have used it to verify hashes or domains to identify malicious activity, trigger playbooks that automate and gather endpoint logs, block malicious processes, and update incident tickets, showcasing end-to-end processes with automation in investigation and reducing the analysis workflow."
"The active threat dashboard is the most valuable feature of this solution."
"Darktrace has helped our organization be secure from network spam and attacks."
"It provides a comprehensive, detailed view of network activity and whatever is happening inside it."
"It is very easy to work with Darktrace once you know how it works and the type of permissions that you need to get related to the security over a network. The interface is awesome. I'm sure that you have seen Ironman, and you know Jarvis, the computer of Tony Stark. The interface of Darktrace is very similar, and you can see in 3D, like a hologram, the whole network, traffic, and all the traces inside the network. The interface is awesome, and it provides a lot of information. At least for us, it is very easy to handle this interface, get the reports, and do the interpretation of those reports. Darktrace also provides mobile monitoring. With an app on your mobile phone, you can view the information live, which is very useful for area directors and field engineers. Darktrace can be also correlated with any type of big data solution, such as Splunk."
"It is really good; it has given us a view of our company and it has actually caught a couple of people that were doing data exfiltration and stealing data from our company, and we caught them doing it in the act in live time, which is just incredible."
"AI analytics are built directly into the product."
"The most valuable feature is that it works autonomously."
"The most valuable feature of Darktrace and the most valuable feature is the artificial intelligence module because that is the tool that determines automatically if there is any risk or not in the network."
"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

"Cortex XDR by Palo Alto Networks could improve its user interface, which is more complicated compared to competitors such as SentinelOne."
"Previously, the endpoint would leave the environment, not being on our VPN, essentially unable to interact with the server to upload files. It was unable to retrieve new file verdicts. It was using a thing called "local analysis" to determine if something was a malicious file or not. There was no dynamic analysis."
"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 core analysis, and security analysis, Cortex needs to provide more information."
"This is a very costly product."
"Limited remote connection."
"A better pricing plan would make this product more competitive."
"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."
"The module can improve so that every time it's more intelligent."
"I would like to see more protection in the endpoint. Especially because we have a lot of people using VPNs."
"It should be easier to access the Darktrace portal and its documentation. Only the customer can access their portal and support. It could be cheaper."
"The solution would benefit from automation. Currently, you have to know what you are searching for."
"The solution could be easier to use."
"As of now, I feel Darktrace can be improved to better detect end device activities, such as laptops or desktops, to bind it with our network."
"The pricing model is a little too high and could be more flexible."
"Block attack capabilities or integration with other SIEM solutions such as IBM QRadar."
"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

"I don't like that they have different types of licenses."
"I don't have any issues with the pricing. We are satisfied with the price."
"The price of the solution could be reduced. I have customers that have voiced that the solution is good for the value but if I want to sell more of the solution the price reduction would help."
"The solution is expensive. It's pricing is on a yearly-basis."
"Cortex XDR’s pricing is very reasonable."
"Traps pays for itself within the first 16 months of a three-year subscription. This is attributed to OPEX savings, as security teams spent less time trying to identify and isolate malware for analysis as a result of a reduction in malware incidents, false positives, and breach avoidance."
"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."
"The pricing is quite high, estimated at around $350,000 per year."
"I'm unfamiliar with the exact cost, but we have a yearly license and had to pay for Darktrace's services before the deployment. The product is very expensive, so some organizations can't afford to pay the total amount directly, meaning they often seek a partner or pay in installments, which increases the price more."
"If you consider the features and the cost of market leaders, we are satisfied with the pricing."
"When it comes to large installations, it can be expensive, but for small accounts it's fine."
"This solution is expensive."
"Darktrace is pricey, but the price is reasonable for what the solution does, and it's comparable to other products."
"It is pretty expensive, but it is worth it. Its licensing is yearly."
"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."
"It’s a single license platform."
