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 good thing about the product is that it's always scanning."
"The solution allows control over the user and his machine through Cortex XDR security policies."
"It is a simple platform to use."
"The initial setup is pretty easy."
"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."
"From the Palo Alto side, whatever they buy, they integrate that really well into their integration suite, and that makes a massive difference."
"The protection offered by this product is good, as is the endpoint reporting."
"The product's initial setup phase is very easy."
"The solution is outstanding from a monitoring perspective."
"I have found the most valuable features to be artificial intelligence for cybersecurity, advanced machine learning capabilities, enterprise Immune System, Antigena Network, and Antigena Email. The way the solution detects the threat over the network before it spreads is very good. It notifies you of what the threat is exactly doing and gives you all the details about the execution of that application that had created the threat over your network."
"I particularly like Antigena and the analytics around the real-time monitoring of our network. I also like its reporting because it has got a seven-day reporting period within the system. Every time you run the reports, it gives you the data about the previous seven days. I like that because it is in real-time. I enjoy reading those reports and getting a very clear and decisive idea of what's happening on my network on a real-time basis. I like the actual real-time monitoring of spoofing and things like that. I also like the user monitoring as well as the network logging capabilities."
"The product is extremely stable and mature."
"Technical support is helpful and responsive."
"The scalability of Darktrace is very high."
"The most valuable feature is the solution's ability to trim out the false positives and point your attention to the real important stuff."
"We're very pleased with Darktrace so it is a bit difficult to pinpoint areas for improvement."
"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

"The playbooks could be improved to include more functionalities or actions."
"It would be better if they could educate the customers more. Some sort of seminars and roadshows will help educate the customers and show what the product can do. The price could be better. It would also help if they had a team for deployment and support."
"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."
"One thing that was missing was the integration part. Currently, they don't have out-of-box integration with IBM QRadar, or if they have the integration, the integration doesn't work well."
"The tool needs to be improved in terms of integration and interface."
"I would like to see them include NDR (Network Detection Response)."
"In reporting they should have a customizable dashboard due to the fact that C-level people don't like reporting to the IT department. They prefer to have a real-time dashboard. That kind of dashboard needs to have various customizations."
"Cortex XDR by Palo Alto Networks could improve by adding a sandbox feature to better compete with their competitors which have it."
"The solution can improve the reporting. Currently, it only runs weekly and the reporting is complex."
"I would like to see a feature where the tool ingests information from an anti-malware product that is present at the endpoint."
"The pricing is costly in USD, and they charge based on device counts."
"The one downside is the pricing, which is quite high."
"It's quite expensive to have."
"In terms of improvements, fine-tuning is the area where we have to spend some time because it works on unsupervised machine learning. It would be good if they can improve their algorithm or technical functionality to reduce the fine-tuning effort. They can also come up with something at the endpoint level. So far, Darktrace has been a network detection response (NDR) solution. It does not offer much at the endpoint level or on user-client devices or servers. There should be more visibility at the endpoint level. It would be good to have the detection and response at the endpoint level by Darktrace. It should also have integration with an agile environment so that we can have continuous development and continuous integration in the application development environment. This is currently not there. It should also have internet-facing platform visibility, which is currently missing. They also need to improve the reporting and management dashboards. Currently, these are not so easy for a non-technical person. All these features would make Darktrace much better, and they would also be helpful in selling more solutions."
"In a shared environment, it doesn't work, and there are still some integration issues."
"The pricing is based on the number of endpoints, so the program is rather expensive."
"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

"The pricing seems fair, and I do like the licensing model. You use wherever they are, and it is elastic."
"Cortex XDR is a costly solution."
"Our license will require renewal in August, after which the maintenance will continue as usual."
"Cortex XDR by Palo Alto Networks is quite an expensive solution."
"I am using the Community edition."
"I don't have any issues with the pricing. We are satisfied with the price."
"The price was fine."
"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 pricing is very flexible for Darktrace. Sometimes, a customer does not have the appropriate budget, but Darktrace can handle that. They offer monthly payments, so the customer can acquire the solution very easily."
"In the ballpark, we're talking about $30K, $50K, and up. It can even be as much as $50K or $100K."
"The product is expensive."
"I am using a demo of Darktrace for deployment and testing which is free."
"It is expensive."
"It is a very expensive product."
"We had an issue with pricing initially and had to cancel some of the features of the projects to fit the budget. I would like to see pricing that is not broken up into parts so that we can buy the whole package once. Darktrace is more expensive than an average solution, but it's functionality won't match that of an average solution."
"They are too expensive compared with other vendors."
"It’s a single license platform."
