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 of the solution is very good. We have about 100 users on it right now, and we use it twice a week."
"It is a simple platform to use."
"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."
"One of the main benefits of the solution is its intelligence to correlate the events into an incident."
"We have a complete overview of all our PCs and it's very easy to handle and to use the interface. It has a lot of benefits for us."
"Implementing Cortex XDR by Palo Alto Networks has had a significant impact on my security analyst workload because it becomes much easier."
"The live terminal is probably the best thing ever. It gives you the access to get straight onto any machine."
"Since they've done their most recent update, the ease to isolate endpoints is valuable. If we find one where there is a virus on it, we can easily isolate it. We don't even have to contact the user. We don't have to manually take them off the network. We can easily isolate them."
"It provides a comprehensive cybersecurity solution that monitors my cloud accounts as well as my local network."
"Technical support is great. They are very responsive and helpful."
"The AI-based pattern is the most valuable feature."
"It is a stable solution."
"It is very stable and easy to use."
"We are able to detect a lot of things, actually, and see what is happening in our network."
"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."
"It is a very simple product to use."
"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

"There's an overall lack of features."
"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."
"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."
"Currently, we are monitoring all USB drives and ports but we would like to improve our device control capabilities."
"The server sometimes stops continuously to check things so it would be helpful to receive access updates or technical reasons."
"Every 30 or 40 days, there's a new version and we need to go and make sure our customer's laptops are upgraded."
"On the pricing aspect, Cortex XDR by Palo Alto Networks needs to have a more reasonable rate, particularly for customers in Sri Lanka and Asian countries."
"The GUI could be improved. It's a little bit cumbersome. It could be more user-friendly."
"The product doesn't have an endpoint agent that can react to triggers set on the device,"
"It would be useful if there was a way to check to see if there are certain devices that are not in sync with the solution. I'm not sure if this is an option or not."
"The user interface and the configuration are a bit complex and should be improved or simplified."
"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."
"The stability isn't good but I like the product."
"The interface is too mathematical and it should be simplified."
"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."
"It can have more integration with orchestration or event management solutions."
"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

"The solution is expensive. It's pricing is on a yearly-basis."
"The cost of Cortex XDR by Palo Alto Networks is $55 to $90 USD per endpoint per month."
"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."
"It has reasonable pricing for the use cases it provides to the company."
"Cortex XDR by Palo Alto Networks is quite an expensive solution."
"I don't recall what the cost was, but it wasn't really that expensive."
"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."
"The price of Darktrace is high and could be reduced. We pay approximately $30,000 to $54,000 annually."
"The pricing is reasonable."
"Prior to negotiating, Darktrace offered their appliance and service for $80,000 per year."
"It is inexpensive considering what it can do and the competition."
"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."
"The product is expensive."
"The pricing is very flexible for Darktrace. Sometimes, a customer does not have the appropriate budget, but Darktrace can handle that. They offer monthly payments, so the customer can acquire the solution very easily."
"It's an expensive solution."
"It’s a single license platform."
