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

"Once you become familiar with it, Cortex XDR by Palo Alto Networks is a more powerful tool and I would say that I prefer it over MDE because it is a stronger tool for me."
"The solution doesn't need a high level of technical training."
"The most valuable for us is the correlation feature."
"Cortex XDR alerts us on the dashboard when there's a threat, which allows us to restrict that user and helps secure our infrastructure."
"One of the things that I enjoy the most is using policy extensions. It's like having host firewalls to control USB connections. I think it's a wonderful tool to restrict use when connecting to our computers. Another important tool is Home Insights. That is an add-on to the Cortex solution. I like that because we can see all the vulnerabilities in the environment and control what assets are connected to our network."
"The best feature of Cortex XDR by Palo Alto Networks is that it collects logs from different sections such as the endpoint, the network, and the cloud, making it easy to investigate alerts, collect some of the investigation packages related to the infected machines, and provide live response."
"What I like about Cortex XDR by Palo Alto Networks is that it is a comprehensive solution that contains everything the organization may need when using endpoints."
"The ability to kind of stitch everything together and see the actual complete picture is very useful. I guess you'd call it a playbook. Some people call it the forensics analysis of what was happening on particular endpoints when they detected some malicious behavior, and what transpired before that to cause that. It is also very user friendly. The way they have done everything and integrated all the solutions that they've purchased over the years to make it a very seamless, effective product is very good. One thing about Palo Alto is that they take the products or services that they purchase and make them seamless for the end user as compared to some companies that purchase other companies and then just kind of have their products off to the side or keep different interfaces. Palo Alto doesn't do that."
"I can rate Darktrace's technical support as one of the best products in the world."
"The most valuable feature is the solution's ability to trim out the false positives and point your attention to the real important stuff."
"The features that are most valuable to me include detection, response with analytics, and network detection."
"I like the dashboards, which are cool. They are more user-friendly, in my experience. Its learning capabilities are really good."
"I am a very happy user and a happy seller of Darktrace."
"Its most valuable feature is its ability to identify malicious connected IPs from outside and the attacks that get through to the inside."
"One member of staff is enough for deployment and maintenance because Darkforce is AI-driven. It does a lot of things by itself."
"We allow customers to access our Wi-Fi as guests, and some of them were going to restricted sites. Darktrace showed us what they were doing so we could block them."
"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

"There are some default policies which sometimes affect our applications and cause them to run around."
"The server sometimes stops continuously to check things so it would be helpful to receive access updates or technical reasons."
"Based on our experience so far, its implementation is quite complex."
"The solution needs better reports. I think they should let the customer go in and customize the reports."
"I have run into some detection issues with Cortex XDR. It needs to be better at detection of internal attacks."
"Fine-tuning the detection policy requires experience because the policy is very complex in Cortex XDR by Palo Alto Networks, and we get high false positive alerts."
"The main issue I could point out is the offline agents and the way that it is missing."
"They've been having some issues with updating their endpoint agents, and it has been quite frustrating."
"Darktrace needs to automate the reports of false positives, botnets and everything."
"It's a very complex platform."
"The management dashboards and the meter dashboards should be more user-friendly and simple to use for easy management."
"The interface and dashboards could be improved for ease-of-use."
"The user interface and the configuration are a bit complex and should be improved or simplified."
"Its threat analyzer could be better. It should also have agents."
"Pricing bothers me and this is one of the major factors when choosing a solution."
"It can have more integration with orchestration or event management solutions."
"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

"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 return on investment is from the user side because we have seen the performance of it increase the delivery time of the product if we are using too many web-based and on-premise applications. In indirect ways, we saw the return of investment in terms of performance and user satisfaction increase."
"Our customers have expressed that the price is high."
"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."
"The tool's price is moderate."
"It has reasonable pricing for the use cases it provides to the company."
"The price is on the higher side, but it's okay."
"It has a yearly renewal."
"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 inexpensive considering what it can do and the competition."
"They are too expensive compared with other vendors."
"The pricing is a little high compared to the competition."
"It is pretty expensive, but it is worth it. Its licensing is yearly."
"The pricing is expensive. It costs over $100,000 a year."
"It's an expensive solution."
"When it comes to large installations, it can be expensive, but for small accounts it's fine."
"It’s a single license platform."
