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 product is very good, it has caught a lot of exploits that most products would not."
"After installing this solution, it identified, blocked, and provided the complete attack chain, which was very helpful."
"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."
"The anti-exploit is impenetrable. We chose Traps because it is the only product that we were not able to get anything past."
"Overall, it's a great platform; it integrates very well with other solutions from Palo Alto and also with our vendors, the ease of use is excellent, I love the root cause analysis from Cortex, which is amazing, and in a few clicks you can have the full root cause."
"We've had a significant increase in blocking with a decrease in false positives, because it's looking at how the files work, not just a list of files that it's been told to look for."
"What I like about Cortex XDR by Palo Alto Networks is that it is a comprehensive solution that contains everything the organization may need when using endpoints."
"The correlation with the firewall and the creation of policies by areas have facilitated security management in my company by allowing me to create more fine-tuned policies that take into account multiple aspects of the operation, multiple effects, multiple sources, and multiple destinations."
"AI analytics are built directly into the product."
"The most valuable feature of Darktrace is the AI that detects abnormal network activity."
"The most valuable part of the product is the whole package, as the features included in the Enterprise Immune System are complete and effective and its detection engine is ridiculously good."
"Darktrace is very flexible."
"The most valuable features of Darktrace are its full capabilities, as you have visibility of everything happening on your network, emails, and SaaS applications."
"Darktrace has helped our organization be secure from network spam and attacks."
"The ability to detect activity on the network is very useful to us. Even if it's not necessarily an illegal activity, if it is abnormal activity, it is able to detect it and notify us."
"I have found the automation and AI features to be valuable. If someone were to come in to the office at midnight and log in, Darktrace would flag it."
"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

"Traps doesn't work with McAfee. You need to remove McAfee to install Traps. This is very common, and its nothing that should be an issue. Some antivirus engines recognize Traps as an threat component, so maybe they need to shake hands somewhere."
"The GUI could be improved."
"Dashboards do not allow everyone to see what's happening."
"It'll help if customization was easier."
"We have found that there are times Cortex XDR by Palo Alto Networks does not detect some of the viruses, we have to use another protection solution called Kaspersky."
"Cortex XDR is trickier to configure than other Palo Alto products. This is one area where we are not so satisfied."
"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 would like to see them include NDR (Network Detection Response). Then it would work well with SIEM Response."
"I feel that Darktrace could be improved, particularly in the support aspect which is currently very poor. We need to chase Darktrace instead of them being proactive with us."
"The pricing is a bit high for the region."
"I did not use the AI features because they should make it more user-friendly which would be a benefit. Additionally, the solution could integrate with more SIEM or SOAR tools."
"Needs to improve its collaboration with local partners."
"It could build in integrations for some complementary products, but it has an assistant plugin so this is not really a big deal."
"I would like to see a feature where the tool ingests information from an anti-malware product that is present at the endpoint."
"This is quite an expensive product so the pricing is something that can be improved."
"The cost of the solution is expensive for smaller businesses."
"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."
