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

"Threat identification and detection are the most valuable features of this solution."
"The solution's stability is generally good."
"It detected stuff that other things wouldn't detect."
"Cortex XDR is stable, offering high quality and reliable performance."
"The initial setup is pretty easy."
"They did what they said. This solution could apply to any scenario."
"One of the main benefits of the solution is its intelligence to correlate the events into an incident."
"From the Palo Alto side, whatever they buy, they integrate that really well into their integration suite, and that makes a massive difference."
"The most valuable features of Darktrace are its full capabilities. You have visibility of everything."
"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 beneficial feature in Darktrace is identifying phishing emails with the help of the AI engine and machine learning."
"We're very pleased with Darktrace so it is a bit difficult to pinpoint areas for improvement."
"The product is extremely stable and mature."
"The NDR is good in their solution and they have NTG for email."
"I have used multiple solutions, but its graphical user interface is quite interesting and quite descriptive, with a lot of video animations where we can easily see how the data is transferred between various points, and it is also quite easy to understand for a new user."
"It provides a comprehensive cybersecurity solution that monitors my cloud accounts as well as my local 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

"Being able to filter the events to see those that are related to the actual alert would save time spent by the engineer."
"There is also no recovery feature; if some endpoint is under attack there must be the possibility of recovering it or restoring it to a normal state."
"Cortex does not offer an on-premises solution. However, some customers would prefer not to be on the cloud. It would be ideal if it could offer something on-prem as well."
"The tool needs to be improved in terms of integration and interface."
"For Cortex XDR by Palo Alto Networks, if I had to point out improvements, I would say the UI is still somewhat difficult for beginners."
"Basically, they don't provide customer support tools just to investigate the logs."
"There's room for improvement with Mac device installations, which can be challenging."
"For working with the solution, you only really need a web browser, however, we've found that working on Chrome, for example, is horrible."
"It would be useful if there was a way to check to see if there are certain devices that are not in sync with the solution. I'm not sure if this is an option or not."
"It would be good if they can include some endpoint protection for remote workers."
"The Darktrace Mobile app needs improvement as it's currently limited in functionality, and the learning AI takes a while to adapt to new devices, flagging new users as threats for up to a month before recognizing them as regular network users."
"A reporting portal could be a great addition to help customize reports."
"One area for improvement is the alerting system, which generates too many alerts and becomes labor-intensive for organizations not equipped with enough personnel in their SOC."
"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 management dashboards and the meter dashboards should be more user-friendly and simple to use for easy management."
"The solution's user interface and stability could 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

"The pricing seems fair, and I do like the licensing model. You use wherever they are, and it is elastic."
"The solution has one subscription for endpoint protection and one subscription for detection and response. The two licenses combined give you the BRO version."
"Cortex XDR by Palo Alto Networks is an expensive solution."
"Our license will require renewal in August, after which the maintenance will continue as usual."
"It's the most expensive solution, but features-wise, it's quite strong. It's very good for protection, so the results are very good in the case of protection. I would rate it a two out of ten in terms of pricing."
"Our customers have expressed that the price is high."
"The tool's price is moderate."
"We didn't have to pay any additional fee for the cloud instance. It just came with the renewal, which was nice."
"Darktrace is quite an expensive solution."
"Our customers feel that the price of Darktrace is quite high compared to other solutions."
"The pricing is reasonable."
"It is expensive."
"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."
"The cost is moderate."
"It's an expensive solution."
"It’s a single license platform."
