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 by Palo Alto Networks has helped lighten the load of our security analysts because it was the major tool that we were using and the one we utilized most."

"I can highlight that we have not faced any security incidents with Cortex XDR by Palo Alto Networks, and even though our environment is quite dynamic, we have not faced any security incident with Cortex XDR by Palo Alto Networks until now."

"Cortex XDR by Palo Alto Networks saves time in various ways, although the user interface is fairly standard."

"I have found the solution to be very easy in respect of the integration and configurable."

"If you are looking for security, mainly for advanced threat prevention from ransomware and malware attacks, I would recommend Cortex."

"The product has an intuitive dashboard."

"The integrations are out-of-the-box, as are the playbooks."

"There are a lot of lead solutions in this space, however, Palo Alto is number one."

More Cortex XDR by Palo Alto Networks pros

"The most valuable features are the AI and advanced learning tools that distinguish it from other products."

"Because of unsupervised machine learning, its detection capability is quite good."

"The autonomous mode, which is the Antigena AI response, is particularly valuable."

"They've worked hard to be the top security control in terms of AI and machine learning, and their product works well."

"The models, triggers, and alerts are customizable."

"t was pretty as far as the granularity of what you were getting out of it."

"It has helped the organization to detect any malware affecting the machines...The network monitoring and the email monitoring features are very valuable for us."

"In terms of features, the data or information they collect and unsupervised machine learning are very valuable. Its unsupervised machine learning has reduced our team's effort. Both Darktrace and Vectra work on unsupervised machine learning that learns the behavior or develops a profile on its own, which allows our security team to do some other tasks rather than spending time on Darktrace or Vectra. Because of unsupervised machine learning, its detection capability is quite good. Along with that, if we utilize the integration feature properly, the automated incident response capability of Darktrace is quite useful."

More Darktrace pros

"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

"Palo Alto Networks Cortex XDR does not detect malicious activity like in other anti-virus solutions like Trend Micro and Windows with Cisco."

"The GUI could be improved. It's a little bit cumbersome. It could be more user-friendly."

"The dashboard is the area that needs to improve so that we can have the ability to drill down without having to go elsewhere to verify results."

"There's room for improvement with Mac device installations, which can be challenging."

"The solution lags to the real-time scenarios here and there."

"There are some false positives. What our guys would have liked is that it would have been easier to manipulate as soon as they found a false positive that they knew was a false positive. How to do so was not obvious. Some people complained about it. The interface, the ESM, is not user-friendly."

"Dashboards do not allow everyone to see what's happening."

"The onboarding process could be better."

More Cortex XDR by Palo Alto Networks cons

"This is quite an expensive product so the pricing is something that can be improved."

"The only thing that I can think of that would improve it would be if they had a better visualization and a reporting portal."

"In terms of improvements, fine-tuning is the area where we have to spend some time because it works on unsupervised machine learning. It would be good if they can improve their algorithm or technical functionality to reduce the fine-tuning effort. They can also come up with something at the endpoint level. So far, Darktrace has been a network detection response (NDR) solution. It does not offer much at the endpoint level or on user-client devices or servers. There should be more visibility at the endpoint level. It would be good to have the detection and response at the endpoint level by Darktrace. It should also have integration with an agile environment so that we can have continuous development and continuous integration in the application development environment. This is currently not there. It should also have internet-facing platform visibility, which is currently missing. They also need to improve the reporting and management dashboards. Currently, these are not so easy for a non-technical person. All these features would make Darktrace much better, and they would also be helpful in selling more solutions."

"In the next version, I'd like to see penetration testing."

"The main portal needs improvement as it is difficult to use."

"Darktrace would tell you, for example, if there was a ransomware attack, but it wouldn't stop the attack."

"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."

More Darktrace cons

"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

"The cost depends on your chosen license type, like Pro or other licenses."

"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."

"I am using the Community edition."

"The price is on the higher side, but it's okay."

"Our license will require renewal in August, after which the maintenance will continue as usual."

"Our customers have expressed that the price is high."

"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."

More Cortex XDR by Palo Alto Networks pricing and cost advice

"It is expensive."

"It is inexpensive considering what it can do and the competition."

"In the ballpark, we're talking about $30K, $50K, and up. It can even be as much as $50K or $100K."

"It is expensive. I don't have the price for other competitors."

"It's an expensive solution."

"The pricing is subscription-based and it is high."
