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

"Palo Alto is constantly adding new features."
"It blocks malicious files, prevents attacks, and doesn't require many updates because it is a very light application."
"The product is very good, it has caught a lot of exploits that most products would not."
"Cortex XDR by Palo Alto Networks should be a stable solution."
"Cortex XDR can integrate the firewalls and determine the tendencies of the attacks. It's a new generation antivirus, with protection endpoints and detection response. It is very easy to use and everybody can operate the solution."
"It detected stuff that other things wouldn't detect."
"One of the main benefits of the solution is its intelligence to correlate the events into an incident."
"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."
"The most valuable feature of Darktrace is its ability to detect and counter threats before they occur."
"This solution is both scalable and stable."
"You have visibility, and it will find anything that you miss with other solutions."
"Technical support is great. They are very responsive and helpful."
"The most valuable features are the AI and advanced learning tools that distinguish it from other products."
"Darktrace is valuable since it offers full packet capture and detailed metadata."
"Implementing this solution has given us confidence that we are secure."
"The most valuable part of the product is the whole package, as the features included in the Enterprise Immune System are complete and effective and its detection engine is ridiculously good."
"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 onboarding process could be better."
"This product has not improved my organization - in fact, we are in the process of moving back to another product as a result of Cortex's horrible impact on system performance."
"Fine-tuning the detection policy requires experience because the policy is very complex in Cortex XDR by Palo Alto Networks, and we get high false positive alerts."
"I would like to see some additional features related to email protection included."
"There's room for improvement with Mac device installations, which can be challenging."
"One thing that was missing was the integration part. Currently, they don't have out-of-box integration with IBM QRadar, or if they have the integration, the integration doesn't work well."
"There is also no recovery feature; if some endpoint is under attack there must be the possibility of recovering it or restoring it to a normal state."
"The solution should offer more dashboards and they should be better customized."
"This product needs more in terms of prevention."
"I would like to see some additional enhancements."
"Needs to improve its collaboration with local partners."
"Its threat analyzer could be better. It should also have agents. They should improve this product by installing agents for the machine to get more visibility. Currently, they are monitoring only the network. They should also monitor the agents from inside. It should also have a better pricing plan because it is an expensive product."
"Darktrace could improve its features, such as monitoring and detecting ransomware."
"There aren't so many third-party vendor platforms natively integrated with the platform."
"The initial setup is a bit complex."
"The management dashboards and the meter dashboards should be more user-friendly and simple to use for easy management."
"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

"The pricing is a little high. It is per user per year."
"Cortex XDR by Palo Alto Networks is an expensive solution."
"It has reasonable pricing for the use cases it provides to the company."
"The cost of Cortex XDR by Palo Alto Networks is $55 to $90 USD per endpoint per month."
"Cortex XDR’s pricing is very reasonable."
"It is "expensive" and flexible."
"Every customer has to pay for a license because it doesn't work with what you get from a managed services provider."
"The price of the solution is high for the license and in general."
"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 am using a demo of Darktrace for deployment and testing which is free."
"In the ballpark, we're talking about $30K, $50K, and up. It can even be as much as $50K or $100K."
"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."
"When it comes to large installations, it can be expensive, but for small accounts it's fine."
"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."
"It is pretty expensive, but it is worth it. Its licensing is yearly."
"It’s a single license platform."
