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:

"The dashboard is customizable."
"The solution is a new generation XDR that has a lot of artificial intelligence modules."
"Technical support is the best in class, in my opinion, because they have invested heavily in research and development."

Cons

"The playbooks could be improved to include more functionalities or actions."
"I would like to see some additional features related to email protection included."
"Technology evolves every day, so it would be nice if it gets more secure. It can also have more integration with other platforms."
"Cortex XDR could improve its sales support team, including better commission structures and referral programs."
"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."
"It's not an ideal choice for smaller businesses, as you need a minimum of 200 endpoints to even use the solution at all."
"Every 30 or 40 days, there's a new version and we need to go and make sure our customer's laptops are upgraded."
"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 could improve by being more user-friendly."
"There aren't so many third-party vendor platforms natively integrated with the platform."
"I think there is some MSSP missing."
"The management dashboards and the meter dashboards should be more user-friendly and simple to use for easy management."
"The solution would benefit from automation. Currently, you have to know what you are searching for."
"In an upcoming release, there could be more customizable playbooks or a library of playbooks to choose from."
"If asked to rate Darktrace support on a scale from zero to ten where ten is the best, I would give them five points."
"Darktrace does not have any capabilities to configure. So I would like to see supervised machines and capabilities in the next version."
"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

"Every customer has to pay for a license because it doesn't work with what you get from a managed services provider."
"Cortex XDR by Palo Alto Networks is an expensive solution."
"Compared to CrowdStrike, Cortex XDR is an expensive solution."
"Its pricing is kind of in line with its competitors and everybody else out there."
"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."
"We pay about $50,000 USD per year for a bundle that includes Cortex XDR."
"Cortex XDR by Palo Alto Networks is quite an expensive solution."
"The price is on the higher side, but it's okay."

"Prior to negotiating, Darktrace offered their appliance and service for $80,000 per year."
"They are too expensive compared with other vendors."
"It’s a single license platform."
