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 us to gain remote access without the user's knowledge and take the necessary actions on the device."
"Cortex XDR by Palo Alto Networks has helped lighten the load of our security analysts because it was the major tool that we were using and the one we utilized most."
"The most valuable features are the fact that it was running in the background and it would intercept any weird stuff, and the fact that it would send things directly to the cloud for sandboxing. It's quite practical."
"The tool is designed to scale for large enterprises and handle large volumes of data."
"The level of security I get for my endpoints and servers is extremely valuable."
"Stability is a primary factor, and then there's the ease of distribution and policy management; Cortex XDR by Palo Alto Networks is very easy to work with, and we're quite happy with them."
"I like that the product has behavior-based detection which offers many benefits over signature-based detection."
"It detected stuff that other things wouldn't detect."
"It's beneficial to me and I can see that with more time and energy put into optimizing it and personalizing the unit, it can be much more powerful than the way I am using it now."
"The solution is stable. We've never had any problems with it."
"I particularly like Antigena and the analytics around the real-time monitoring of our network. I also like its reporting because it has got a seven-day reporting period within the system. Every time you run the reports, it gives you the data about the previous seven days. I like that because it is in real-time. I enjoy reading those reports and getting a very clear and decisive idea of what's happening on my network on a real-time basis. I like the actual real-time monitoring of spoofing and things like that. I also like the user monitoring as well as the network logging capabilities."
"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."
"We are able to detect a lot of things, actually, and see what is happening in our network."
"It is a stable solution without downtime."
"The solution is powerful and very useful, it has the ability to avert many attacks."
"The most valuable feature is the endpoint protection."
"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 downsides of Cortex XDR by Palo Alto Networks are that in many incidents, when I enter the causality chain, there are numerous logs."
"A better pricing plan would make this product more competitive."
"They have the worst support, as a company, that I have ever worked with, as they are difficult to get a hold of and keep on the phone. They don't know what they are talking about when you get them on the phone. They don't like to respond to messages when you send them to them. They like to "research problems" for weeks on end, then pass you off to somebody else."
"The solution can never really be an on-premises solution based simply on the way it is set up. It needs metadata to run and improve. Having an on-premises solution would cut it off from making improvements."
"A little bit more automation would be nice."
"The downside to the solution is that there are a large number of false positives."
"The solution needs better reports. I think they should let the customer go in and customize the reports."
"I recommend adding a data loss prevention (DLP) solution to Cortex XDR by Palo Alto Networks. The inclusion of this feature would allow the application of DLP policies alongside antivirus policies via a single agent and console, making it more competitive as other OEMs often offer DLP solutions as part of their antivirus products."
"The only thing that I can think of that would improve it would be if they had a better visualization and a reporting portal."
"The technical support is not very good."
"In an upcoming release, there could be more customizable playbooks or a library of playbooks to choose from."
"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."
"It's quite expensive to have."
"The price point for the product was too high for what our possible use case could be."
"I would like to see some additional enhancements."
"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 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 price of the solution could be reduced. I have customers that have voiced that the solution is good for the value but if I want to sell more of the solution the price reduction would help."
"Cortex XDR’s pricing is very reasonable."
"The solution has one subscription for endpoint protection and one subscription for detection and response. The two licenses combined give you the BRO version."
"The pricing is okay, although direct support can be expensive."
"The tool's price is moderate."
"It has reasonable pricing for the use cases it provides to the company."
"Licensing for Palo Alto Networks Cortex XDR can be costly, especially when it comes to a hundred users. A license is required for each user, and the subscription must be renewed on a yearly basis."
"It is "expensive" and flexible."
"The pricing is subscription-based and it is high."
"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."
"This solution is expensive."
"All of the other modules, such as the licensing modules, are on par. It's one for one."
"The cost is moderate."
"The price of Darktrace is high and could be reduced. We pay approximately $30,000 to $54,000 annually."
"The tool's pricing is costly."
"If you consider the features and the cost of market leaders, we are satisfied with the pricing."
"It’s a single license platform."
