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.

Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"But overall, when we speak about security and protection, they are one of the top providers."
"Stability-wise, it is good; I did not hear about any issues in terms of stability, and Cortex XDR by Palo Alto Networks can be trusted completely."
"Cortex XDR by Palo Alto Networks has changed the way my security team detects, investigates, and responds to threats, as we are able to see the files, unwanted files, unsecured files, and unauthorized files, so we are quarantining them."
"When the pandemic started, Palo Alto came up with many solutions, which helped with the quick shift from on-premises to the cloud."
"Based on my experience with Cortex XDR by Palo Alto Networks, I highly recommend it due to its quick response to zero-day attacks and low utilization from end-user devices."
"It'll not slow down your system when compared to others."
"If you are looking to deploy a security solution as a whole, this is a good option."
"The solution's most valuable feature is its ability to rapidly detect certain hardware files."
"A very useful feature in Darktrace for real-time threat analysis is the packet inspection that analyzes the packet traffic in real time."
"It is a very simple product to use."
"The most beneficial feature in Darktrace is identifying phishing emails with the help of the AI engine and machine learning."
"The Antigena feature is very useful."
"The solution automatically monitors everything on the network to prevent anti-phishing by monitoring, responding, and restoring the system."
"While it is complex, and difficult to use, once you understand the correct way to use it, it's a very good platform."
"I can rate Darktrace's technical support as one of the best products in the world."
"Darktrace's most valuable features are that it understands the network environment and is able to trace the traffic and alert on anomalies."
"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

"The connection to the internet has not performed as expected."
"The price could be a little lower."
"Cortex XDR by Palo Alto Networks is a strong tool, but it is true that digesting information sometimes makes the tool go a little bit slower."
"If they had pulse rate detection, it would be better."
"It's more focused on network communication. If a customer wants to increase the level of protection and start working with documents, it's impossible to integrate these features into the system. It's more of a communication-oriented system than a content security-oriented system."
"Although I would say this product is highly-rated, it could probably do more because nothing does everything that you want."
"In the next release, I would like to see more UI improvements. Their UI is a bit basic. When we are speaking about Palo Alto Networks they are the big company, so they can improve the UI a little bit. The UI, the reports, the log system can all be improved."
"The dashboard could use some significant improvement, just making it more useful with more information. It has a limited amount of information right now. It is customizable, but I'd love to see a better out-of-box dashboard."
"It would be good if they can include some endpoint protection for remote workers. Nowadays, most people are working remotely. Therefore, they should include some type of sensors that can be installed on the endpoint in order to directly report the main usage and protect remotely. Phone protection will also be a great feature to add to Darktrace."
"Darktrace needs to simplify most of the positive reports. We have to field all the positive reports, false positives, too."
"The solution's user interface and stability could be improved."
"I was under impression that Darktrace's automatic blocking would be an out-of-the-box feature, but we had to integrate it with our firewall to get it to block automatically. The salesperson should be upfront and explain that you need to integrate it with your network. I would also like to see more reporting on risk. Banks in my region want to see at a glance the risk level of various assets."
"Darktrace could improve its features, such as monitoring and detecting ransomware."
"Pricing bothers me and this is one of the major factors when choosing a solution."
"Needs to improve its collaboration with local partners."
"One thing I would like is for Darktrace to flag SMB traffic more accurately. Currently, it only flags that SMB traffic has occurred, but it doesn't specify which file was being transferred. This makes it difficult to investigate incidents involving SMB traffic, as we don't have concrete evidence of what was being sent."
"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

"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."
"Compared to CrowdStrike, Cortex XDR is an expensive solution."
"It is "expensive" and flexible."
"Cortex XDR by Palo Alto Networks is an expensive solution."
"Very costly product."
"We didn't have to pay any additional fee for the cloud instance. It just came with the renewal, which was nice."
"This is an expensive solution."
"In terms of the cost Cortex XDR by Palo Alto Networks is very expensive because we are a Mexican company and when you translate dollars to pesos the cost is very high. The solution is very expensive for Mexican companies. I understand that they have international prices, but I do not think it offsets the price enough for many companies in countries, such as Mexico. The amount it is reduced is not a massive percentage."
"It was $3,600 a month or $2,000 plus or so. I am not sure. Its licensing is pretty simple."
"The cost is moderate."
"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."
"It is a very expensive product."
"Darktrace is expensive. You can pay for the license yearly."
"All of the other modules, such as the licensing modules, are on par. It's one for one."
"Darktrace is quite an expensive solution."
"The price of the solution is not cheap. It is not a one-time purchase, there is a subscription that needs to be paid every one to five years depending on your choice. It is expensive but you can reduce the price by only using the services that you want."
"It’s a single license platform."
