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 solution allows control over the user and his machine through Cortex XDR security policies."
"Cortex XDR by Palo Alto Networks is easy to use and does not consume a lot of hardware resources."
"If the user leaves our premises or network, Palo Alto Traps will still be on that endpoint and will still apply our policies."
"The initial setup is pretty easy."
"Cortex XDR by Palo Alto Networks should be a stable solution."
"The solution allows us to make investigations. Other XDR solutions also provide similar capabilities but for investigation, Cortex XDR is better."
"One thing that I like about Cortex XDR by Palo Alto Networks, it is detecting all the suspicious or malicious binaries, and it has integration with Palo Alto Firewall."
"My advice for others looking into using Cortex is that it is very easy to use and very useful for the customer environment, whether it's a public or private one."
"The most valuable feature of this solution is that it does not require human intervention to eliminate a threat; it blocks everything automatically."
"Darktrace is extremely stable."
"AI analytics are built directly into the product."
"The technical support is excellent; they walk you through the process and do a great job."
"The Antigena feature is very useful."
"A simple, powerful AI solution that just does all the work for you when you turn it on."
"Darktrace has helped our organization be secure from network spam and attacks."
"It is really good; it has given us a view of our company and it has actually caught a couple of people that were doing data exfiltration and stealing data from our company, and we caught them doing it in the act in live time, which is just incredible."
"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."
"To jump from the partner to Palo Alto directly was challenging."
"It's very time-consuming to log support issues and the people that answer the tickets aren't very knowledgeable."
"It is a complex solution to implement."
"The encryption is not up to the mark."
"Cortex XDR could be improved with more GUI features."
"There are some limitations on the Traps agents."
"While using Cortex, I noticed some aspects that could be improved, such as increasing the synchronization speed between XDR and Xnor."
"The solution could be easier to use."
"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."
"This product needs more in terms of prevention."
"If asked to rate Darktrace support on a scale from zero to ten where ten is the best, I would give them five points."
"I would like to see some additional enhancements."
"The pricing is a bit high for the region."
"They just need to work on their price."
"It's quite expensive to have."
"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

"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."
"The cost depends on your chosen license type, like Pro or other licenses."
"The price was fine."
"It has reasonable pricing for the use cases it provides to the company."
"It has a higher cost than other solutions, like CrowdStrike or Microsoft’s EDR tools, but it reduces the cost of our operations because it’s a new generation antivirus tool."
"Cortex XDR's pricing is ok."
"The tool's price is moderate."
"The return on investment is from the user side because we have seen the performance of it increase the delivery time of the product if we are using too many web-based and on-premise applications. In indirect ways, we saw the return of investment in terms of performance and user satisfaction increase."
"Prior to negotiating, Darktrace offered their appliance and service for $80,000 per year."
"The solution is about $6,000 per quarter."
"The cost of the solution can be reduced to make it more appealing to customers."
"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."
"Darktrace is expensive. You can pay for the license yearly."
"Our customers feel that the price of Darktrace is quite high compared to other solutions."
"It is expensive. I don't have the price for other competitors."
"They are too expensive compared with other vendors."
"It’s a single license platform."
