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

"Palo Alto Networks Traps improves our security posture and lowers risk by providing next-gen methods to combat against modern threats on all the major platforms."
"They did what they said, and this solution could apply to any scenario."
"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."
"Cortex XDR can integrate the firewalls and determine the tendencies of the attacks. It's a new generation antivirus, with protection endpoints and detection response. It is very easy to use and everybody can operate the solution."
"Stability is one of the features we like the most."
"They have a new GUI which is just fantastic."
"From the Palo Alto side, whatever they buy, they integrate that really well into their integration suite, and that makes a massive difference."
"The live terminal is probably the best thing ever. It gives you the access to get straight onto any machine."
"Technical support is helpful and responsive."
"Overall, this is a good product that seems to be working well."
"The solution automatically monitors everything on the network to prevent anti-phishing by monitoring, responding, and restoring the system."
"A simple, powerful AI solution that just does all the work for you when you turn it on."
"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."
"Darktrace is valuable since it offers full packet capture and detailed metadata."
"This is something that is really easy to implement in an organization, gives us good visibility about what is happening in our networks and on the system, and we like the transparency available within our infrastructure now."
"You have visibility, and it will find anything that you miss with other solutions."
"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 playbooks could be improved to include more functionalities or actions."
"The installation should be easier and the Palo Alto pre-sales and sales teams should have more information on the product because they don't know what they are selling."
"They are charging for Network Traffic Analyzer (NTA) services, so if the per GB data could be provided at a certain level free of cost or at the same cost which the customer is taking for the entire bundle, that would be better."
"The installation should be easier and the Palo Alto pre-sales and sales teams should have more information on the product because they don't know what they are selling."
"This is a very costly product."
"The solution lags to the real-time scenarios here and there."
"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."
"Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth."
"The interface and dashboards could be improved for ease-of-use."
"Darktrace could improve its features, such as monitoring and detecting ransomware."
"I would like to see some additional enhancements."
"Although we haven't detected any network threats since implementing Darktrace, we are unsure of its efficacy. It would be beneficial if the solution could offer additional details to the user regarding any potential or prevented threats. Additionally, there could be better search tools and integration."
"The pricing is a bit high for the region."
"Darkforce could be improved in the range of the interface; how to interact with the actions it's taking or not taking."
"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 solution's user interface and stability could be improved."
"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’s pricing is very reasonable."
"Cortex XDR by Palo Alto Networks is quite an expensive solution."
"I am using the Community edition."
"The pricing is okay, although direct support can be expensive."
"The cost depends on your chosen license type, like Pro or other licenses."
"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."
"The price is on the higher side, but it's okay."
