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.

Monitoring has improved data loss detection and now spots abnormal internal file transfers quickly
In my understanding, the best feature Darktrace offers is the identification of copying files, which acts as a DLP, and it is a main concern for companies because users sometimes copy data outside without knowing, especially those without a technical background. When I mention the DLP-like feature and file copying detection, the alerts have been very timely, as we get an alert within a couple of minutes, which is excellent. Even if some developers are working after hours and copying files, our SOC team detects this, and most of the time they call us so we can identify the users. The alerts are quite accurate and proactive.

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

"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."
"This software helps us understand any issues that may arise when someone is not at work."
"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."
"The most valuable aspect of Cortex XDR by Palo Alto Networks for me is its integration with AI detection, where we get to know the behavioral detection based on users, traffic patterns, and different services that we consume."
"The product's most valuable features are massive user and feature intelligence exploit detection."
"The scalability of Cortex XDR by Palo Alto Networks is very good."
"After installing this solution, it identified, blocked, and provided the complete attack chain, which was very helpful."
"These days it's machine-learning technology and behavior-based analytics features that make us more secure."
"A very useful feature in Darktrace for real-time threat analysis is the packet inspection that analyzes the packet traffic in real time."
"I have used multiple solutions, but its graphical user interface is quite interesting and quite descriptive. There are a lot of video animations, and we can easily see how the data is transferred between various points. That's something really interesting. It is also quite easy to understand for a new user."
"AI analytics are built directly into the product."
"The NDR is good in their solution and they have NTG for email."
"The scalability of Darktrace is very high."
"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."
"I can rate Darktrace's technical support as one of the best products in the world."
"This solution can reduce the resources required to run a security operation center by two-thirds."
"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 main issue I could point out is the offline agents and the way that it is missing."
"The solution should force customers to integrate with network traffic to see the full benefits of XDR."
"Palo Alto Networks Cortex XDR does not detect malicious activity like in other anti-virus solutions like Trend Micro and Windows with Cisco."
"Cortex XDR by Palo Alto Networks could improve by adding a sandbox feature to better compete with their competitors which have it."
"Cortex XDR by Palo Alto Networks could improve by offering remote management. It would be useful to look at the client's issue to fix it."
"The solution lags to the real-time scenarios here and there."
"Being able to filter the events to see those that are related to the actual alert would save time spent by the engineer."
"Based on our experience so far, its implementation is quite complex."
"The solution can improve the reporting. Currently, it only runs weekly and the reporting is complex."
"The dashboard and reporting for this solution could be improved as it is currently complex. The GUI for this solution could also be improved."
"The main portal needs improvement as it is difficult to use."
"Darktrace needs to simplify most of the positive reports. We have to field all the positive reports, false positives, too."
"The pricing is expensive. It costs over $100,000 a year."
"The solution could have better integration capabilities."
"The product doesn't have an endpoint agent that can react to triggers set on the device,"
"Darktrace requires numerous configurations. It would be beneficial if the configuration could be made simpler."
"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

"Our customers have expressed that the price is high."
"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 pricing is okay, although direct support can be expensive."
"The pricing is a little bit on the expensive side."
"Its pricing is kind of in line with its competitors and everybody else out there."
"Compared to CrowdStrike, Cortex XDR is an expensive solution."
"It's about $55 per license on a yearly basis."
"The solution is expensive. It's pricing is on a yearly-basis."
"It is expensive."
"The cost is moderate."
"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."
"It was $3,600 a month or $2,000 plus or so. I am not sure. Its licensing is pretty simple."
"It is a very expensive product."
"There is an annual license to use Darktrace."
"It is inexpensive considering what it can do and the competition."
"The pricing is expensive. It costs over $100,000 a year."
"It’s a single license platform."
