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

"My advice for others looking into using Cortex is that it is very easy to use and very useful for the customer environment, whether it's a public or private one."
"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."
"Implementing Cortex XDR by Palo Alto Networks has had a significant impact on my security analyst workload because it becomes much easier."
"Being a cloud solution it is very flexible in serving internal and external connections and a broad range of devices."
"It has pretty much everything we need and works well within the Palo Alto ecosystem."
"The product is very good, it has caught a lot of exploits that most products would not."
"Previously, we had to install endpoint protection per machine and then scan and update, but Cortex XDR basically does that centrally and predictably, so we have more time to do day-to-day work rather than spend time chasing those endpoints."
"We've had a significant increase in blocking with a decrease in false positives, because it's looking at how the files work, not just a list of files that it's been told to look for."
"t was pretty as far as the granularity of what you were getting out of it."
"What I like about Darktrace, is that you can quickly identify threats."
"It is very easy to work with Darktrace once you know how it works and the type of permissions that you need to get related to the security over a network. The interface is awesome. I'm sure that you have seen Ironman, and you know Jarvis, the computer of Tony Stark. The interface of Darktrace is very similar, and you can see in 3D, like a hologram, the whole network, traffic, and all the traces inside the network. The interface is awesome, and it provides a lot of information. At least for us, it is very easy to handle this interface, get the reports, and do the interpretation of those reports. Darktrace also provides mobile monitoring. With an app on your mobile phone, you can view the information live, which is very useful for area directors and field engineers. Darktrace can be also correlated with any type of big data solution, such as Splunk."
"Its AI technology supports cybersecurity by learning my environment and accurately responding to threats."
"The NDR is good in their solution and they have NTG for email."
"Darktrace is very useful for us because it has a large number of models for detecting threats."
"Artificial intelligence and machine learning functionalities are valuable."
"The most valuable feature of this solution is that it does not require human intervention to eliminate a threat; it blocks everything automatically."
"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

"I feel that it should not be a licensed activity because a feature should allow us to see applications running on end devices."
"Palo Alto Networks Cortex XDR does not detect malicious activity like in other anti-virus solutions like Trend Micro and Windows with Cisco."
"If he is using a smaller company, he can depend on some other tools because Cortex XDR by Palo Alto Networks is a bit expensive."
"It's very time-consuming to log support issues and the people that answer the tickets aren't very knowledgeable."
"Additionally, I think the price is very high, and if it can be adjusted, I believe it will be a very good solution."
"There are some limitations on the Traps agents."
"Currently, if you use Palo Alto endpoint protection as the only solution it's very complicated to remove pre-existing threats."
"I think sometimes Cortex XDR agent automatically stops event capturing from the device, and then even the dashboard does not get any notifications from the agent."
"The solution would benefit from automation. Currently, you have to know what you are searching for."
"We'd like threat hunting, and we'd like to see a global solution that can automate vulnerability scans. I know it is something they are working on."
"Darktrace could improve by being more user-friendly."
"Darktrace could expand into EDR (endpoint detection and response) and combine it with its network detection."
"Block attack capabilities or integration with other SIEM solutions such as IBM QRadar."
"The pricing is expensive. It costs over $100,000 a year."
"Its documentation is not up to the mark. At times, I have a lot of trouble finding a solution."
"It would be useful if there was a way to check to see if there are certain devices that are not in sync with the solution. I'm not sure if this is an option or not."
"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 solution has one subscription for endpoint protection and one subscription for detection and response. The two licenses combined give you the BRO version."
"Cortex XDR by Palo Alto Networks is an expensive solution."
"It is cost-effective compared to similar solutions. It fits for the small businesses through to the big businesses."
"I don't have any issues with the pricing. We are satisfied with the price."
"Cortex XDR by Palo Alto Networks is quite an expensive solution."
"The price is on the higher side, but it's okay."
"The cost depends on your chosen license type, like Pro or other licenses."
"Every customer has to pay for a license because it doesn't work with what you get from a managed services provider."
"When it comes to large installations, it can be expensive, but for small accounts it's fine."
"It's an expensive solution."
"It was $3,600 a month or $2,000 plus or so. I am not sure. Its licensing is pretty simple."
"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 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."
"I am using a demo of Darktrace for deployment and testing which is free."
"The tool's pricing is costly."
"In the ballpark, we're talking about $30K, $50K, and up. It can even be as much as $50K or $100K."
"It’s a single license platform."
