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

"Cortex is a very good total solution on the endpoints."
"I don't have to do much monitoring with it; I don't have to have anybody manually looking at this, it gives us reports, and it lets us know if something needs to be addressed, and we can easily address it."
"The most valuable feature of Cortex XDR by Palo Alto Networks is its machine-learning capabilities. Additionally, there is full integration with other solutions."
"The stability is pretty good except for one or two cases, and based on the performance, it's been okay with pretty high performance, no bugs or glitches, and it doesn't crash or freeze."
"When the pandemic started, Palo Alto came up with many solutions, which helped with the quick shift from on-premises to the cloud."
"Cortex is the best solution for avoiding security breaches, malware attacks, and other kinds of security issues."
"We can visualize and control the activities in the environment from anywhere."
"The biggest positive impact I see from Cortex XDR by Palo Alto Networks is a significant reduction in the number of people required to manage it."
"It's a very stable product."
"A very useful feature in Darktrace for real-time threat analysis is the packet inspection that analyzes the packet traffic in real time."
"This is something that is really easy to implement in an organization, gives us good visibility about what is happening in our networks and on the system, and we like the transparency available within our infrastructure now."
"What I like about Darktrace, is that you can quickly identify threats."
"The most valuable feature is the alerts. The alerts are meaningful. The event rolls up into meaningful and actionable alerts rather than just being noise."
"Because of unsupervised machine learning, its detection capability is quite good."
"The product can scale."
"The most valuable feature has been the behavioral analytics that allows us to monitor all the traffic."
"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

"They are charging for Network Traffic Analyzer (NTA) services, so if the per GB data could be provided at a certain level free of cost or at the same cost which the customer is taking for the entire bundle, that would be better."
"There is a severe gap in functionality between Windows, Linux, and Mac versions. For example all folder restriction settings are Windows only. Traps 5.0+ does not have SAML / LDAP integration."
"It'll help if customization was easier."
"Cortex XDR by Palo Alto Networks is not only pricey; it is extremely expensive."
"There are some default policies which sometimes affect our applications and cause them to run around."
"Technology evolves every day, so it would be nice if it gets more secure. It can also have more integration with other platforms."
"The installation should be easier and the Palo Alto pre-sales and sales teams should have more information on the product because they don't know what they are selling."
"It's very time-consuming to log support issues and the people that answer the tickets aren't very knowledgeable."
"Darktrace should have more automation and integrations with other security monitoring tools."
"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."
"Block attack capabilities or integration with other SIEM solutions such as IBM QRadar."
"They just need to work on their price."
"The pricing is based on the number of endpoints, so the program is rather expensive."
"The Darktrace Mobile app needs improvement as it's currently limited in functionality, and the learning AI takes a while to adapt to new devices, flagging new users as threats for up to a month before recognizing them as regular network users."
"I would like to see a feature where the tool ingests information from an anti-malware product that is present at the endpoint."
"The level of tracking within the network from the transmission level up to the machine level can use improvement."
"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

"This is an expensive solution."
"Compared to CrowdStrike, Cortex XDR is an expensive solution."
"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."
"We pay about $50,000 USD per year for a bundle that includes Cortex XDR."
"Cortex XDR by Palo Alto Networks is an expensive solution."
"The pricing is a little high. It is per user per year."
"Cortex XDR by Palo Alto Networks is quite an expensive solution."
"It's the most expensive solution, but features-wise, it's quite strong. It's very good for protection, so the results are very good in the case of protection. I would rate it a two out of ten in terms of pricing."
"It's an expensive solution."
"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."
"All of the other modules, such as the licensing modules, are on par. It's one for one."
"Darktrace is expensive. You can pay for the license yearly."
"There is an annual license to use Darktrace."
"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."
"The pricing is subscription-based and it is high."
"It is expensive. I don't have the price for other competitors."
"It’s a single license platform."
