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

"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."
"Its ability to react to cyber data attacks is awesome. That is pretty much the use of it. What blows your mind is the ability to access your assets remotely and see what is actually going on with them. You can not only see them in a console. You can also react very rapidly to your assets that are compromised."
"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."
"We can visualize and control the activities in the environment from anywhere."
"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's a nice product that's stable and scalable."
"Its interface and pricing are most valuable, and it is better than other vendors in terms of security."
"There has been a significant reduction of approximately 70% to 80% in our internal MTTR and MTTD metrics, now around five to eight minutes whereas previously it was hours, which has helped tremendously."
"Its most valuable feature is its ability to identify malicious connected IPs from outside and the attacks that get through to the inside."
"The product is extremely stable and mature."
"The features that are most valuable to me include detection, response with analytics, and network detection."
"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."
"I particularly like Antigena and the analytics around the real-time monitoring of our network."
"The Antigena feature is most valuable. Once it learns your environment, Antigena can step in and block a denial of service attack, a ransomware attack, or just about anything that doesn't belong in the environment. It can detect any type of attack that hits the environment because it understands what normal looks like for the network. It is very useful for an autonomous response."
"Darktrace is very flexible."
"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."
"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

"Although I would say this product is highly-rated, it could probably do more because nothing does everything that you want."
"It is an enterprise-level solution. Its price could be less expensive."
"The solution should add unwanted malicious hash values to a block list so that whenever the action is triggered, it will automatically prevent the malicious content."
"The MAC agent is not as robust feature-wise as the PC version."
"I am facing issues with customer support for Cortex XDR by Palo Alto Networks, so I am not satisfied with customer support."
"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."
"As an improvement, I would like to see enhanced connection speeds."
"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."
"It's a very complex platform."
"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."
"This is quite an expensive product so the pricing is something that can be improved."
"The only thing that I can think of that would improve it would be if they had a better visualization and a reporting portal."
"There is a high ratio of false positive information."
"This product needs more in terms of prevention. The detection capabilities work well but once a threat has been detected, Darktrace should work to prevent it from doing anything malicious."
"The product doesn't have an endpoint agent that can react to triggers set on the device,"
"The dashboard and reporting for this solution could be improved as it is currently complex. The GUI for this solution could also be improved."
"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."
"Cortex XDR by Palo Alto Networks is an expensive solution."
"It has a yearly renewal."
"It is cost-effective compared to similar solutions. It fits for the small businesses through to the big businesses."
"It's about $55 per license on a yearly basis."
"It has a higher cost than other solutions, like CrowdStrike or Microsoft’s EDR tools, but it reduces the cost of our operations because it’s a new generation antivirus tool."
"Our license will require renewal in August, after which the maintenance will continue as usual."
"I don't like that they have different types of licenses."
"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 cost is moderate."
"The pricing is subscription-based and it is high."
"It is expensive. I don't have the price for other competitors."
"The pricing is reasonable."
"It is pretty expensive, but it is worth it. Its licensing is yearly."
"Darktrace is pricey, but the price is reasonable for what the solution does, and it's comparable to other products."
"Our customers feel that the price of Darktrace is quite high compared to other solutions."
"It’s a single license platform."
