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.

Consistent threat hunting and anomaly detection deliver valuable insights for network security management
In terms of improvement for Darktrace, pricing is the main concern. Pricing bothers me and this is one of the major factors when choosing a solution. When we get feedback from customers, that's the only felt need. When we factor in Darktrace, we do it only limited. We put it on where the perimeters and connections are, but still, some gray areas are left out, especially if we have multiple branches. We need Darktrace on each branch to get the data out, and I suggest having some kind of a centralized product that gets data from multiple sources to aggregate and provide the data.

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

"The most valuable aspect of Cortex XDR by Palo Alto Networks for me is its integration with AI detection, where we get to know the behavioral detection based on users, traffic patterns, and different services that we consume."
"The stability of the solution is very good. We have about 100 users on it right now, and we use it twice a week."
"Its interface and pricing are most valuable. It is better than other vendors in terms of security."
"The positive impacts I see from Cortex XDR by Palo Alto Networks include a complete 360-degree view of our security posture altogether, being a uniform platform where we are ingesting logs from multiple resources."
"The initial setup is pretty easy."
"Its ability to react to cyber data attacks is awesome."
"The solution doesn't need a high level of technical training."
"The most valuable features are incident creation, policy-based protection, IP whitelisting, and device encryption. These are beneficial for endpoint and server security."
"While it is complex, and difficult to use, once you understand the correct way to use it, it's a very good platform."
"The product offers us a very good user interface and we've found the network visibility to be very good so far."
"You have visibility, and it will find anything that you miss with other solutions."
"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."
"I like the dashboards, which are cool. They are more user-friendly, in my experience. Its learning capabilities are really good."
"The ability to see what we have not seen before is most valuable. It is very interesting to find out the most vulnerable devices in our network."
"I would 100% recommend Darktrace."
"The technical support from Darktrace is very good, including support from their resellers."
"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

"We had a problem with getting our older endpoints up to date, but their newest updates have been really good."
"Cortex XDR could improve its sales support team, including better commission structures and referral programs."
"Data privacy is a matter of concern. You have to be careful with data privacy, it can be sensitive and Cortex can have most of your access."
"When it comes to core analysis and security analysis, Cortex needs to provide more information."
"It automatically detects security issues. It should be able to protect our network devices while operating autonomously."
"Data privacy is a matter of concern. You have to be careful with data privacy, it can be sensitive and Cortex can have most of your access."
"Palo Alto Networks Cortex XDR does not detect malicious activity like in other anti-virus solutions like Trend Micro and Windows with Cisco."
"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 should be easier to access the Darktrace portal and its documentation. Only the customer can access their portal and support. It could be cheaper."
"The cost is a bit on the higher side."
"Block attack capabilities or integration with other SIEM solutions such as IBM QRadar."
"The product is considered expensive compared to others."
"The level of tracking within the network from the transmission level up to the machine level can use improvement."
"I would like for the product to work on the endpoints as well. I would like to see enhanced visibility into the endpoints and network but this solution only sits on the network itself."
"I think there is some MSSP missing."
"Darktrace does not have any capabilities to configure."
"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

"I don't have any issues with the pricing. We are satisfied with the price."
"It's about $55 per license on a yearly basis."
"The cost depends on your chosen license type, like Pro or other licenses."
"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."
"Cortex XDR by Palo Alto Networks is quite an expensive solution."
"Cortex XDR's pricing is ok."
"We pay about $50,000 USD per year for a bundle that includes Cortex XDR."
"It has a yearly renewal."
"The cost of the solution can be reduced to make it more appealing to customers."
"The cost of the solution is expensive for smaller businesses. They will not be able to afford it or might not need this type of security solution."
"It is expensive. I don't have the price for other competitors."
"The pricing is a little high compared to the competition."
"When it comes to large installations, it can be expensive, but for small accounts it's fine."
"I am using a demo of Darktrace for deployment and testing which is free."
"It was $3,600 a month or $2,000 plus or so. I am not sure. Its licensing is pretty simple."
"We had an issue with pricing initially and had to cancel some of the features of the projects to fit the budget. I would like to see pricing that is not broken up into parts so that we can buy the whole package once. Darktrace is more expensive than an average solution, but it's functionality won't match that of an average solution."
"It’s a single license platform."
