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

"It is a simple platform to use."
"I've found the solution to be highly scalable for enterprises."
"They have a new GUI which is just fantastic."
"The best feature of Cortex XDR by Palo Alto Networks is that it collects logs from different sections such as the endpoint, the network, and the cloud, making it easy to investigate alerts, collect some of the investigation packages related to the infected machines, and provide live response."
"It blocks malicious files, prevents attacks, and doesn't require many updates because it is a very light application."
"These days it's machine-learning technology and behavior-based analytics features that make us more secure."
"In one single alert, we are getting the network telemetry, endpoint telemetry, email security telemetry, and proxy telemetry all in one single ticket, making it very easy."
"Cortex XDR alerts us on the dashboard when there's a threat, which allows us to restrict that user and helps secure our infrastructure."
"The most valuable feature of Darktrace is its ability to detect and counter threats before they occur."
"Darktrace is extremely stable."
"Based on our experience with DarkTrace, I would advise that if they are comparing prices, ROI and everything, I think Darktrace is better than FireEye."
"Overall, this is a good product that seems to be working well."
"Its most valuable feature is its ability to identify malicious connected IPs from outside and the attacks that get through to the inside."
"The ability to see what we have not seen before is most valuable. It is very interesting to find out the most vulnerable devices in our network."
"It has helped the organization to detect any malware affecting the machines...The network monitoring and the email monitoring features are very valuable for us."
"The product is extremely stable and mature."
"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 product's pricing could be better."
"Based on our experience so far, its implementation is quite complex."
"The solution lags to the real-time scenarios here and there."
"It takes time to scan the servers and devices."
"I have seen lagging with Cortex XDR by Palo Alto Networks. There was one time when we faced a threat actor trying to gain access to our system. When our team utilized the tool, we were all on the same dashboard and we faced a lag issue at that time of around five minutes, which was quite significant."
"I would like to see them include NDR (Network Detection Response). Then it would work well with SIEM Response."
"Impact on system performance is horrible, adding a lot of delays for users."
"The downsides of Cortex XDR by Palo Alto Networks are that in many incidents, when I enter the causality chain, there are numerous logs."
"We want to continue using Darktrace but it's very expensive."
"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."
"The solution would benefit from automation. Currently, you have to know what you are searching for."
"The pricing is a bit high for the region."
"The cost of the solution is quite high."
"They are too expensive compared with other vendors."
"The solution can improve the reporting. Currently, it only runs weekly and the reporting is complex."
"Its documentation is not up to the mark. At times, I have a lot of trouble finding a solution. Even when I posted questions on the community chats, it took a lot of time for me to get answers. That's something that can be improved. Darktrace can focus on creating a more interactive community. If there are more people from Darktrace to focus on community chats, it would be better."
"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

"We didn't have to pay any additional fee for the cloud instance. It just came with the renewal, which was nice."
"It is "expensive" and flexible."
"The pricing is a little high. It is per user per year."
"The pricing seems fair, and I do like the licensing model. You use wherever they are, and it is elastic."
"This is an expensive solution."
"It's way too expensive, but security is expensive. You pay for your licensing, and then you pay for someone to monitor the stuff."
"I don't recall what the cost was, but it wasn't really that expensive."
"Cortex XDR’s pricing is very reasonable."
"We've budgeted about 50,000 Kuwaiti dinars for the solution. That is a yearly operating cost."
"Darktrace is quite an expensive solution."
"The pricing is expensive. It costs over $100,000 a year."
"It's an expensive solution."
"It is a very expensive product."
"All of the other modules, such as the licensing modules, are on par. It's one for one."
"The cost of the solution is expensive for smaller businesses. They will not be able to afford it or might not need this type of security solution."
"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’s a single license platform."
