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

"The policy configuration is great, the granularity of policies that are available is very helpful, it is straightforward to set up, and it has pretty much everything we need and works well within the Palo Alto ecosystem."
"Their XDR agent and their behavioral indicators of compromise (BIOC) are pretty nice. Their managed threat hunting is also pretty nice. They also have WildFire, which is a service for actively looking for malware. It's quite useful."
"Palo Alto is the core of the security infrastructure in the environment."
"The most valuable feature is that you can select remote access of any machine for sandboxing."
"The main benefit of using Cortex XDR by Palo Alto Networks while employing Palo Alto Firewall at the internet edge is that it improves security on our endpoint devices, integrating seamlessly with Palo Alto Firewalls to deliver comprehensive network, analyst, and security details all in a single dashboard, which allows us to manage everything from our network devices."
"Cortex XDR by Palo Alto Networks's ability to block sophisticated threats in real time is quite good and is on par with SentinelOne's."
"The product has an intuitive dashboard."
"Has great threat detection capabilities."
"Darktrace's most valuable features are that it understands the network environment and is able to trace the traffic and alert on anomalies."
"The most valuable feature of Darktrace is the AI that detects abnormal network activity."
"The most valuable feature is that it works autonomously."
"The most valuable feature of this solution is that it does not require human intervention to eliminate a threat; it blocks everything automatically."
"The platform has many modules, and each module examines a different situation in the behavior."
"I am a very happy user and a happy seller of Darktrace."
"It's a very stable product."
"Implementing this solution has given us confidence that we are secure."
"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

"Palo Alto Networks Cortex XDR does not detect malicious activity like in other anti-virus solutions like Trend Micro and Windows with Cisco."
"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."
"It tends to do 99.9% of things. The only thing I'd like is single sign-on authentication into their cloud platform so that my users can be properly authenticated against it."
"It is not very strong in terms of endpoint management. It should have additional features like DLP, encryption, or advanced device control. Currently, Cortex is good in terms of the security of the endpoints, but it is not as good as other vendors in terms of the management of the endpoint."
"It's very time-consuming to log support issues and the people that answer the tickets aren't very knowledgeable."
"A better pricing plan would make this product more competitive."
"Every 30 or 40 days, there's a new version and we need to go and make sure our customer's laptops are upgraded."
"They've been having some issues with updating their endpoint agents, and it has been quite frustrating."
"If asked to rate Darktrace support on a scale from zero to ten where ten is the best, I would give them five points."
"The pricing is expensive. It costs over $100,000 a year."
"It would be good if they can include some endpoint protection for remote workers."
"Updates keep coming, which is great, but I prefer a unified UI experience. The intelligence section and the incident view should be seamlessly connected in one view to avoid jumping between pages."
"The solution could have better integration capabilities."
"Darktrace could improve its features, such as monitoring and detecting ransomware."
"The technical support is not very good."
"Its documentation is not up to the mark. At times, I have a lot of trouble finding a solution. Even when I posted questions on the community chats, it took a lot of time for me to get answers. That's something that can be improved. Darktrace can focus on creating a more interactive community. If there are more people from Darktrace to focus on community chats, it would be better."
"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

"Licensing for Palo Alto Networks Cortex XDR can be costly, especially when it comes to a hundred users. A license is required for each user, and the subscription must be renewed on a yearly basis."
"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."
"Cortex XDR by Palo Alto Networks is quite an expensive solution."
"It is "expensive" and flexible."
"Our license will require renewal in August, after which the maintenance will continue as usual."
"The price of the solution is high for the license and in general."
"The pricing is a little bit on the expensive side."
"It has reasonable pricing for the use cases it provides to the company."
"The pricing is quite high, estimated at around $350,000 per year."
"We had an issue with pricing initially and had to cancel some of the features of the projects to fit the budget. I would like to see pricing that is not broken up into parts so that we can buy the whole package once. Darktrace is more expensive than an average solution, but it's functionality won't match that of an average solution."
"Our customers feel that the price of Darktrace is quite high compared to other solutions."
"The cost of the solution can be reduced to make it more appealing to customers."
"The cost is moderate."
"If you consider the features and the cost of market leaders, we are satisfied with the pricing."
"It's an expensive solution."
"The pricing is expensive. It costs over $100,000 a year."
"It’s a single license platform."
