Senior Process Expert at A.P. Moller - Maersk
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

"We have a complete overview of all our PCs and it's very easy to handle and to use the interface. It has a lot of benefits for us."
"The integrations are out-of-the-box, as are the playbooks."
"The level of security I get for my endpoints and servers is extremely valuable."
"We can visualize and control the activities in the environment from anywhere."
"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."
"Cortex XDR alerts us on the dashboard when there's a threat, which allows us to restrict that user and helps secure our infrastructure."
"It's very stable. I've never experienced downtime for the ASM console or ASM core."
"The anti-exploit is impenetrable. We chose Traps because it is the only product that we were not able to get anything past."
"It is autonomous. So, it learns. It uses algorithms and AI to learn the common behavioral patterns on the network, and it is able to identify threats based on abnormal patterns."
"t was pretty as far as the granularity of what you were getting out of it."
"I can rate Darktrace's technical support as one of the best products in the world."
"The most valuable feature is the alerts. The alerts are meaningful. The event rolls up into meaningful and actionable alerts rather than just being noise."
"A simple, powerful AI solution that just does all the work for you when you turn it on."
"We have found the product to be stable and issue-free."
"The Enterprise Immune System, Cyber Artificial Intelligence Analyst, and Antigena technology are all very useful aspects of the product."
"It is very stable and easy to use."
"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

"It would be good to have a better way to search for a file within the UI."
"In reporting they should have a customizable dashboard due to the fact that C-level people don't like reporting to the IT department. They prefer to have a real-time dashboard. That kind of dashboard needs to have various customizations."
"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."
"There's an overall lack of features."
"They have the worst support, as a company, that I have ever worked with, as they are difficult to get a hold of and keep on the phone. They don't know what they are talking about when you get them on the phone. They don't like to respond to messages when you send them to them. They like to "research problems" for weeks on end, then pass you off to somebody else."
"The solution should add unwanted malicious hash values to a block list so that whenever the action is triggered, it will automatically prevent the malicious content."
"It's not an ideal choice for smaller businesses, as you need a minimum of 200 endpoints to even use the solution at all."
"It takes time to scan the servers and devices."
"I feel that Darktrace could be improved, particularly in the support aspect which is currently very poor. We need to chase Darktrace instead of them being proactive with us."
"Its documentation is not up to the mark. At times, I have a lot of trouble finding a solution."
"They just need to work on their price. In terms of features, we are trying to understand all the features that we have. We're still exploring everything that we have so that we can fully utilize it. At this point in time, it is not about the features. It is more about utilization. We're just trying to utilize everything to full capacity."
"They just need to make it a little bit more accurate as far as their alerts are concerned. It does generate some false positives that you have to tune. You have to do a lot of tuning when you first get it because of the false positives, but once it is all tuned up and ready to go, it will do its thing from there."
"The technical support is not very good."
"Darktrace needs to automate the reports of false positives, botnets and everything."
"It's quite expensive to have."
"The module can improve so that every time it's more intelligent."
"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 is "expensive" and flexible."
"I am using the Community edition."
"In terms of the cost Cortex XDR by Palo Alto Networks is very expensive because we are a Mexican company and when you translate dollars to pesos the cost is very high. The solution is very expensive for Mexican companies. I understand that they have international prices, but I do not think it offsets the price enough for many companies in countries, such as Mexico. The amount it is reduced is not a massive percentage."
"The solution is expensive. It's pricing is on a yearly-basis."
"The cost of Cortex XDR by Palo Alto Networks is $55 to $90 USD per endpoint per month."
"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."
"The price of the solution is high for the license and in general."
"It's way too expensive, but security is expensive. You pay for your licensing, and then you pay for someone to monitor the stuff."
"We've budgeted about 50,000 Kuwaiti dinars for the solution. That is a yearly operating cost."
"It's an expensive solution."
"This solution is expensive."
"They are too expensive compared with other vendors."
"It is expensive. I don't have the price for other competitors."
"Prior to negotiating, Darktrace offered their appliance and service for $80,000 per year."
"Darktrace is pricey, but the price is reasonable for what the solution does, and it's comparable to other products."
"When it comes to large installations, it can be expensive, but for small accounts it's fine."
"It’s a single license platform."
