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

"Its interface and pricing are most valuable, and it is better than other vendors in terms of security."
"It has absolutely improved the way our organization functions, we are more secure, it is giving us more peace of mind, and it has found malicious activity happening on our endpoints that probably would not have been detected if we didn't have it."
"Cortex XDR by Palo Alto Networks should be a stable solution."
"The product's initial setup phase is very easy."
"The level of security I get for my endpoints and servers is extremely valuable."
"Its ability to react to cyber data attacks is awesome. That is pretty much the use of it. What blows your mind is the ability to access your assets remotely and see what is actually going on with them. You can not only see them in a console. You can also react very rapidly to your assets that are compromised."
"Based on my experience with Cortex XDR by Palo Alto Networks, I highly recommend it due to its quick response to zero-day attacks and low utilization from end-user devices."
"I don't have to do much monitoring with it; I don't have to have anybody manually looking at this, it gives us reports, and it lets us know if something needs to be addressed, and we can easily address it."
"Ability to see events and exactly what traffic or website the device had tried to connect to that raised the alert or issue."
"Darktrace is very useful for us because it has a large number of models for detecting threats."
"The technical support from Darktrace is very good, including support from their resellers."
"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 features are the AI and advanced learning tools that distinguish it from other products."
"The support was fantastic, really good."
"The solution is stable. We've never had any problems with it."
"The solution automatically monitors everything on the network to prevent anti-phishing by monitoring, responding, and restoring the system."
"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

"I feel that it should not be a licensed activity because a feature should allow us to see applications running on end devices."
"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."
"It would be good to have a better way to search for a file within the UI."
"There is a severe gap in functionality between Windows, Linux, and Mac versions. For example all folder restriction settings are Windows only. Traps 5.0+ does not have SAML / LDAP integration."
"Based on our experience so far, its implementation is quite complex."
"Being able to filter the events to see those that are related to the actual alert would save time spent by the engineer."
"We had a problem with getting our older endpoints up to date, but their newest updates have been really good. I've been pleased with it in terms of what our needs are. It's doing what we want it to do."
"For working with the solution, you only really need a web browser, however, we've found that working on Chrome, for example, is horrible."
"Darktrace needs to simplify most of the positive reports. We have to field all the positive reports, false positives, too."
"It would be good if they can include some endpoint protection for remote workers."
"There are still some issues with the network capturing or blocking traffic even after implementing exceptions. It requires more learning in this area."
"The management dashboards and the meter dashboards should be more user-friendly and simple to use for easy management."
"Block attack capabilities or integration with other SIEM solutions such as IBM QRadar."
"We'd like threat hunting, and we'd like to see a global solution that can automate vulnerability scans. I know it is something they are working on."
"Darktrace could improve by being more user-friendly."
"Darktrace could improve its features, such as monitoring and detecting ransomware."
"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

"It is "expensive" and flexible."
"Our license will require renewal in August, after which the maintenance will continue as usual."
"We pay about $50,000 USD per year for a bundle that includes Cortex XDR."
"The price is on the higher side, but it's okay."
"It's about $55 per license on a yearly basis."
"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."
"Cortex XDR's pricing is ok."
"The pricing seems fair, and I do like the licensing model. You use wherever they are, and it is elastic."
"The pricing is a little high compared to the competition."
"The cost is moderate."
"Our customers feel that the price of Darktrace is quite high compared to other solutions."
"I am using a demo of Darktrace for deployment and testing which is free."
"They are too expensive compared with other vendors."
"Darktrace is quite an expensive solution."
"The price of the solution is not cheap. It is not a one-time purchase, there is a subscription that needs to be paid every one to five years depending on your choice. It is expensive but you can reduce the price by only using the services that you want."
"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."
