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

"We use Cortex XDR by Palo Alto Networks for its ability to detect based on behavior rather than simple virus scan to prevent malicious activities."
"Monitoring is most valuable."
"It can automatically correlate events and logs, which is very helpful for an IT administrator. It can correlate different kinds of malware activities over a network, agent, or host system. You do not need to do it manually. It is a good feature. It is also a user-friendly solution. We have deployed it on the cloud because our space does not provide any flexibility for on-premises deployment, but Palo Alto has added some flexibility to install it on-premises. It must be like the same Cortex XDR agent for all the VPN services, web filtering services, and everything else."
"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."
"Cortex XDR features advanced threat detection capabilities."
"I recognize that Cortex XDR by Palo Alto Networks is one of the best products in its category regarding capabilities."
"We switched because there were a lot of added features with Palo Alto that Check Point didn't have, and it was an upgrade for us."
"I like that the product has behavior-based detection which offers many benefits over signature-based detection."
"Darktrace has improved our knowledge of abnormal phenomenen which could have potentially be hazardous for the organization."
"The product is extremely stable and mature."
"It's a very stable product."
"Artificial intelligence and machine learning functionalities are valuable."
"It is a stable solution without downtime."
"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."
"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."
"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

"Previously, the endpoint would leave the environment, not being on our VPN, essentially unable to interact with the server to upload files. It was unable to retrieve new file verdicts. It was using a thing called "local analysis" to determine if something was a malicious file or not. There was no dynamic analysis."
"It's very time-consuming to log support issues and the people that answer the tickets aren't very knowledgeable."
"The main issue I could point out is the offline agents and the way that it is missing."
"I don't like that they have different types of licenses. For example, if users select a license, they think they will have all the platforms they need to improve their network or security. But after some time, Palo Alto Networks changed their licensing, and some of the features that, for example, were free at the beginning now have a cost. I think the integration can be improved. For example, a lot of tools are just integrated through APIs."
"Technology evolves every day, so it would be nice if it gets more secure. It can also have more integration with other platforms."
"We have found that there are times Cortex XDR by Palo Alto Networks does not detect some of the viruses, we have to use another protection solution called Kaspersky."
"The price could be a little lower."
"A little bit more automation would be nice."
"I believe their network monitoring device licensing module could use some improvement."
"The dashboard and reporting for this solution could be improved as it is currently complex. The GUI for this solution could also be improved."
"The program is quite expensive."
"A reporting portal could be a great addition to help customize reports."
"This is quite an expensive product so the pricing is something that can be improved."
"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."
"Darktrace should have more automation and integrations with other security monitoring tools."
"The stability isn't good but I like the product."
"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

"Cortex XDR by Palo Alto Networks is an expensive solution."
"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."
"If one wishes to work with another team or large number of users at a future point, he must purchase a license for them."
"The price is on the higher side, but it's okay."
"When we first bought it, it was a bit expensive, but it was worth it. The licensing was straightforward."
"It is cost-effective compared to similar solutions. It fits for the small businesses through to the big businesses."
"Cortex XDR by Palo Alto Networks is quite an expensive solution."
"It's way too expensive, but security is expensive. You pay for your licensing, and then you pay for someone to monitor the stuff."
"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 is expensive. I don't have the price for other competitors."
"Darktrace is expensive. You can pay for the license yearly."
"The cost is moderate."
"There is an annual license to use Darktrace."
"Our customers feel that the price of Darktrace is quite high compared to other solutions."
"I am using a demo of Darktrace for deployment and testing which is free."
"The pricing is reasonable."
"It’s a single license platform."
