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

"Monitoring is most valuable."
"The most valuable features of this product are the management capabilities, which allow an IT organization to get quite a good picture of attempted cyber attacks, and its out-of-the-box investigation capabilities."
"It has pretty much everything we need and works well within the Palo Alto ecosystem."
"It is easy to use."
"The information the dashboard provides is very clear."
"Monitoring is most valuable."
"Cortex XDR by Palo Alto Networks's ability to block sophisticated threats in real time is quite good and is on par with SentinelOne's."
"The most valuable feature of Cortex XDR by Palo Alto Networks is its machine-learning capabilities. Additionally, there is full integration with other solutions."
"It is autonomous, so it learns; it uses algorithms and AI to learn the common behavioral patterns on the network, and it is able to identify threats based on abnormal patterns."
"The technical support from Darktrace is very good, including support from their resellers."
"We have found the product to be stable and issue-free."
"We liked their approach to identifying intrusions or network anomalies using AI."
"The most valuable feature is that it works autonomously."
"Darktrace impacts my organization positively by providing us with a better understanding of abnormal activities detected among users."
"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."
"One member of staff is enough for deployment and maintenance because Darkforce is AI-driven; it does a lot of things by itself."
"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

"We would also like to have advanced tech protection and email scanning."
"It's very time-consuming to log support issues and the people that answer the tickets aren't very knowledgeable."
"Every 30 or 40 days, there's a new version and we need to go and make sure our customer's laptops are upgraded."
"It is not easy to sell Cortex XDR, not because it isn't a good tool. Its marketing needs to be improved."
"Every 30 or 40 days, there's a new version and we need to go and make sure our customer's laptops are upgraded."
"I think sometimes Cortex XDR agent automatically stops event capturing from the device, and then even the dashboard does not get any notifications from the agent."
"While using Cortex, I noticed some aspects that could be improved, such as increasing the synchronization speed between XDR and Xnor."
"There are some limitations on the Traps agents."
"In an upcoming release, there could be more customizable playbooks or a library of playbooks to choose from."
"There are still some issues with the network capturing or blocking traffic even after implementing exceptions. It requires more learning in this area."
"It would be helpful if they could recognize incidents and simplify the customer's challenge to identify what is happening."
"It is expensive, but everything else has been great so far."
"Its documentation is not up to the mark. At times, I have a lot of trouble finding a solution. Even when I posted questions on the community chats, it took a lot of time for me to get answers. That's something that can be improved. Darktrace can focus on creating a more interactive community. If there are more people from Darktrace to focus on community chats, it would be better."
"Darktrace could improve by being more user-friendly."
"The management user interface needs improvement."
"It's a very complex platform."
"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 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."
"Our license will require renewal in August, after which the maintenance will continue as usual."
"Cortex XDR is a costly solution."
"It is cost-effective compared to similar solutions. It fits for the small businesses through to the big businesses."
"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's way too expensive, but security is expensive. You pay for your licensing, and then you pay for someone to monitor the stuff."
"The solution is expensive. It's pricing is on a yearly-basis."
"Cortex XDR's pricing is ok."
"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 quite high, estimated at around $350,000 per year."
"They are too expensive compared with other vendors."
"The tool's pricing is costly."
"Darktrace is quite an expensive solution."
"It is a very expensive product."
"If you consider the features and the cost of market leaders, we are satisfied with the pricing."
"In the ballpark, we're talking about $30K, $50K, and up. It can even be as much as $50K or $100K."
"It’s a single license platform."
