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

"Cortex XDR is stable, offering high quality and reliable performance."
"Overall, it's a great platform; it integrates very well with other solutions from Palo Alto and also with our vendors, the ease of use is excellent, I love the root cause analysis from Cortex, which is amazing, and in a few clicks you can have the full root cause."
"If the user leaves our premises or network, Palo Alto Traps will still be on that endpoint and will still apply our policies."
"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."
"Cortex covers everything I need. It's a perfect solution. Cortex provides a different level of visibility because it's an extended EDR, allowing you to grab logs from the network and firewalls. Palo Alto invented the concept of the extended EDR or XDR."
"I recommend this solution to others because it is easy to manage, reliable, and overall good to use."
"The product is very good, it has caught a lot of exploits that most products would not."
"Stability is one of the features we like the most."
"It is a very simple product to use."
"The solution automatically monitors everything on the network to prevent anti-phishing by monitoring, responding, and restoring the system."
"The ability to detect activity on the network is very useful to us. Even if it's not necessarily an illegal activity, if it is abnormal activity, it is able to detect it and notify us."
"Implementing this solution has given us confidence that we are secure."
"The product can scale."
"I can rate Darktrace's technical support as one of the best products in the world."
"While it is complex, and difficult to use, once you understand the correct way to use it, it's a very good platform."
"Its most valuable feature is its ability to identify malicious connected IPs from outside and the attacks that get through to the inside."
"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

"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 connection to the internet has not performed as expected."
"Cortex XDR could improve its sales support team, including better commission structures and referral programs."
"It'll help if customization was easier."
"The deployment is pretty hard."
"Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth."
"There's an overall lack of features."
"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."
"Its documentation is not up to the mark. At times, I have a lot of trouble finding a solution."
"The program is quite expensive."
"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."
"The pricing is expensive. It costs over $100,000 a year."
"The interface and dashboards could be improved for ease-of-use."
"There aren't so many third-party vendor platforms natively integrated with the platform."
"One area for improvement is the alerting system, which generates too many alerts and becomes labor-intensive for organizations not equipped with enough personnel in their SOC."
"There is no dedicated salesperson in Egypt, and having one would help to improve focus on this market."
"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

"It's way too expensive, but security is expensive. You pay for your licensing, and then you pay for someone to monitor the stuff."
"When we first bought it, it was a bit expensive, but it was worth it. The licensing was straightforward."
"The price was fine."
"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."
"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."
"I am using the Community edition."
"The pricing is a little high. It is per user per year."
"I did PoCs on products called Cylance and CrowdStrike. Although, I consider these products and they were also good, when it come to cost and budgetary factors, Traps has been proven to be better than the other two products. It is quite cost-effective and delivers all the entire solution which we require."
"The pricing is subscription-based and it is high."
"If you consider the features and the cost of market leaders, we are satisfied with the pricing."
"It is inexpensive considering what it can do and the competition."
"It's an expensive solution."
"The pricing is quite high, estimated at around $350,000 per year."
"All of the other modules, such as the licensing modules, are on par. It's one for one."
"I am using a demo of Darktrace for deployment and testing which is free."
"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’s a single license platform."
