Senior Process Expert at A.P. Moller - Maersk
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.

Automated security monitoring increases efficiency, but market visibility needs improvement
I am currently evaluating Stellar Cyber Open XDR in terms of their support. I do not see any major areas for improvement as of now. Their support is good, and the team is small, enabling them to cater to everyone effectively. While I have not encountered significant drawbacks so far, market penetration is challenging due to the product's newness, despite its flexibility and customization features. I find their user interface to be quite good.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The stability is pretty good except for one or two cases, and based on the performance, it's been okay with pretty high performance, no bugs or glitches, and it doesn't crash or freeze."
"It has pretty much everything we need and works well within the Palo Alto ecosystem."
"The policy configuration is great, the granularity of policies that are available is very helpful, it is straightforward to set up, and it has pretty much everything we need and works well within the Palo Alto ecosystem."
"There are a lot of lead solutions in this space, however, Palo Alto is number one."
"Stability-wise, it is good; I did not hear about any issues in terms of stability, and Cortex XDR by Palo Alto Networks can be trusted completely."
"Previously, we had to install endpoint protection per machine and then scan and update, but Cortex XDR basically does that centrally and predictably, so we have more time to do day-to-day work rather than spend time chasing those endpoints."
"Palo Alto is constantly adding new features."
"There has been a significant reduction of approximately 70% to 80% in our internal MTTR and MTTD metrics, now around five to eight minutes whereas previously it was hours, which has helped tremendously."
"Darktrace is valuable since it offers full packet capture and detailed metadata."
"I highly recommend the overall solution to other users and rate it as nine out of ten."
"Its AI technology supports cybersecurity by learning my environment and accurately responding to threats."
"We have found the product to be stable and issue-free."
"You can have a one-person IT team and with Darktrace, you can get notification of potential threats that are incoming or are already happening on the network."
"The most valuable feature of this solution is that it does not require human intervention to eliminate a threat; it blocks everything automatically."
"The most valuable feature in Darktrace is that it gives me a comprehensive, detailed view of my network and whatever is happening inside it."
"The Dynamic Threat Dashboard is very nice, as it lists all of your threats and rates them, and then you can choose whether to investigate further."
"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

"This is a very costly product."
"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."
"They've been having some issues with updating their endpoint agents, and it has been quite frustrating."
"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."
"The connection to the internet has not performed as expected."
"I think Cortex XDR by Palo Alto Networks could be improved by having tiered pricing by device, especially since we have not covered mobile devices because the cost is very high."
"The dashboard is the area that needs to improve so that we can have the ability to drill down without having to go elsewhere to verify results."
"The server sometimes stops continuously to check things so it would be helpful to receive access updates or technical reasons."
"They just need to make it a little bit more accurate as far as their alerts are concerned. It does generate some false positives that you have to tune. You have to do a lot of tuning when you first get it because of the false positives, but once it is all tuned up and ready to go, it will do its thing from there."
"Darktrace needs significant improvement in its notification capabilities."
"It could build in integrations for some complementary products, but it has an assistant plugin so this is not really a big deal."
"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."
"The price point for the product was too high for what our possible use case could be."
"Updates keep coming, which is great, but I prefer a unified UI experience. The intelligence section and the incident view should be seamlessly connected in one view to avoid jumping between pages."
"I believe their network monitoring device licensing module could use some improvement."
"Darktrace needs to simplify most of the positive reports. We have to field all the positive reports, false positives, too."
"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
