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

"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."
"It is an easy-to-use tool."
"One thing that I like about Cortex XDR is its ability to detect all the suspicious or malicious binaries, and it can integrate with Palo Alto Firewall."
"These days it's machine-learning technology and behavior-based analytics features that make us more secure."
"The product is mostly automated, and we do not have to make decisions, because all the decisions are made by the product itself and we are not required to create any custom policies since the policies that are created are well defined in the product itself."
"It is a simple platform to use."
"Cortex covers everything I need. It's a perfect solution. Cortex provides a different level of visibility because it's an extended EDR, allowing you to grab logs from the network and firewalls. Palo Alto invented the concept of the extended EDR or XDR."
"The main benefit of using Cortex XDR by Palo Alto Networks while employing Palo Alto Firewall at the internet edge is that it improves security on our endpoint devices, integrating seamlessly with Palo Alto Firewalls to deliver comprehensive network, analyst, and security details all in a single dashboard, which allows us to manage everything from our network devices."
"I am impressed with the product's ability to give insights into network traffic."
"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."
"The solution is stable. We've never had any problems with it."
"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 feature is the alerts. The alerts are meaningful. The event rolls up into meaningful and actionable alerts rather than just being noise."
"The product is extremely stable and mature."
"Darktrace is very useful for us because it has a large number of models for detecting threats."
"Darktrace is very stable, and I would rate its stability a ten out of ten."
"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

"The connection to the internet has not performed as expected."
"Managing the product should be easier."
"I would like to see some additional features related to email protection included."
"I would like to see them include NDR (Network Detection Response). Then it would work well with SIEM Response."
"It should support more mobile operating systems. That is one of the cons of their infrastructure right now."
"The tool needs to be improved in terms of integration and interface."
"Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth."
"The solution can never really be an on-premises solution based simply on the way it is set up. It needs metadata to run and improve. Having an on-premises solution would cut it off from making improvements."
"The main portal needs improvement as it is difficult to use."
"There are still some issues with the network capturing or blocking traffic even after implementing exceptions."
"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."
"The cost of the solution is quite high."
"It would be good if they can include some endpoint protection for remote workers."
"Darkforce could be improved in the range of the interface; how to interact with the actions it's taking or not taking."
"I did not use the AI features because they should make it more user-friendly which would be a benefit. Additionally, the solution could integrate with more SIEM or SOAR tools."
"Darktrace would tell you, for example, if there was a ransomware attack, but it wouldn't stop the attack."
"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

"Cortex XDR is a costly solution."
"Very costly product."
"It is present, but when compared to other competitive products, I would say it is not less expensive; however, when all of the other added values are considered, the price is reasonable."
"The price of the solution could be reduced. I have customers that have voiced that the solution is good for the value but if I want to sell more of the solution the price reduction would help."
"I don't like that they have different types of licenses."
"It has reasonable pricing for the use cases it provides to the company."
"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's pricing is ok."
"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."
"The price of Darktrace is high and could be reduced. We pay approximately $30,000 to $54,000 annually."
"The pricing is quite high, estimated at around $350,000 per year."
"Darktrace is expensive. You can pay for the license yearly."
"It's an expensive solution."
"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."
"We've budgeted about 50,000 Kuwaiti dinars for the solution. That is a yearly operating cost."
"It’s a single license platform."
