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.

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 feature of Cortex XDR by Palo Alto Networks is its machine-learning capabilities. Additionally, there is full integration with other solutions."

"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 stability of the solution is very good. We have about 100 users on it right now, and we use it twice a week."

"The one feature of Palo Alto Networks Traps that our organization finds most valuable is the App ID service."

"They did what they said. This solution could apply to any scenario."

"Based on my experience, I would recommend Cortex XDR by Palo Alto Networks to other people."

"It has pretty much everything we need and works well within the Palo Alto ecosystem."

"Its interface and pricing are most valuable. It is better than other vendors in terms of security."

More Cortex XDR by Palo Alto Networks pros

"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."

"As we have to service several servers, we can manage them in a economical way, which is beneficial to our team and business."

"We find AlienVault to have the best price to performance value."

"Customer service was very responsive and support was excellent."

"Using the communication within the security device, it is easier to create plugins."

"AlienVault has provided a nice, unified system for monitoring and reporting."

"We evaluated every single SIEM on the market, and the major difference that made AlienVault stand out is the unification, meaning the integration of technologies out-of-the-box, as opposed to having to do it on your own."

"AlienVault gave our organization a centralized tool to manage our security with its intrusion detection, asset management, vulnerability assessments, along with all of its other features, it has become an invaluable asset for our small organization."

"As it includes a logger feature for gathering all logs from all devices (network devices, servers, hosts etc.) it has basically become the only software that we look at when we have a problem."

More USM Anywhere pros

Cons

"There's an overall lack of features."

"There are some third-party solutions that are difficult to integrate with, which is something that can be improved."

"It would be better if they could educate the customers more. Some sort of seminars and roadshows will help educate the customers and show what the product can do. The price could be better. It would also help if they had a team for deployment and support."

"It is not very strong in terms of endpoint management. It should have additional features like DLP, encryption, or advanced device control. Currently, Cortex is good in terms of the security of the endpoints, but it is not as good as other vendors in terms of the management of the endpoint."

"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."

"When it comes to core analysis, and security analysis, Cortex needs to provide more information."

"However, if you do not have Palo Alto in your environment, you are paying these additional services just for Cortex XDR by Palo Alto Networks, so it is not a cost-effective solution."

"Dashboards do not allow everyone to see what's happening."

More Cortex XDR by Palo Alto Networks cons

"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."

"Vendor. Not the best."

"Some customizations with the integration between AlienVault components have room for improvement and enabling users with WebUI interfaces instead of having to edit configuration files on the system to achieve certain actions would be a good improvement."

"I think plugin management should be self-service on AlienVault USM. The other product is self-service but on the USM side. You have to submit a ticket then AT&T creates and updates the plugins."

"Its reporting tools need improvements. It would be good if they can provide integration with other ticketing systems. Currently, we only have integration with Slack and Jira. It is also a bit slow, and its replication engine can be improved."

"I feel that some areas of improvement would be vulnerability scanning. We use a separate product that seems to do a much better job."

"Reporting and Windows log collection is the biggest drawback."

"The log query capability is pretty restrictive and I find myself searching through raw logs via command line more often than the GUI."

"One area that has room for improvement is storage. AllienVault is a good place to put logs, but sometimes it's a tough place to go get logs."

More USM Anywhere cons

Pricing and Cost Advice

"The pricing seems fair, and I do like the licensing model. You use wherever they are, and it is elastic."

"It has a higher cost than other solutions, like CrowdStrike or Microsoft’s EDR tools, but it reduces the cost of our operations because it’s a new generation antivirus tool."

"The price was fine."

"It has reasonable pricing for the use cases it provides to the company."

"It has a yearly renewal."

"Very costly product."

"The price of the solution is high for the license and in general."

"Our license will require renewal in August, after which the maintenance will continue as usual."

More Cortex XDR by Palo Alto Networks pricing and cost advice

"It’s a single license platform."

"It's affordable for most customers."

"I don't think the product's pricing is a good value because they try to raise the price 50 percent every year... AlienVault needs to understand that not all customers are huge enterprises... Their sales team is way too aggressive. The price they advertise is not always the price you get."

"The price of this solution is reasonable, which is one of the reasons why we selected it over other solutions."

"We ran a few PoCs. The price and feature set were the best with AlienVault."

"So far, I feel the product's pricing is a good value. The technology is decent. You get what you pay for. I think it's fair."

"It is a product that is priced in a medium range, making it neither a cheap nor a costly product."

"Its price is much lower than McAfee ESM."

"The ROI is quite good."
