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.

Automated security monitoring increases efficiency, but market visibility needs improvement
I am currently evaluating Stellar Cyber Open XDR in terms of their support. I do not see any major areas for improvement as of now. Their support is good, and the team is small, enabling them to cater to everyone effectively. While I have not encountered significant drawbacks so far, market penetration is challenging due to the product's newness, despite its flexibility and customization features. I find their user interface to be quite good.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Traps pays for itself within the first 16 months of a three-year subscription."
"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."
"It's very stable. I've never experienced downtime for the ASM console or ASM core."
"Cortex is the best solution for avoiding security breaches, malware attacks, and other kinds of security issues."
"Cortex XDR by Palo Alto Networks is easy to use and does not consume a lot of hardware resources."
"The most valuable features are the fact that it was running in the background and it would intercept any weird stuff, and the fact that it would send things directly to the cloud for sandboxing. It's quite practical."
"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."
"Palo Alto is one of the tech vendors that always provides top-of-the-line products."
"SIEM log collection is great, and all of the rules that support updates with maintenance."
"We're using it more for reporting, that's all. We're using it to help our customers to pass any kind of audits that they receive."
"The vulnerability scanning is helpful to identify the areas that need patching or fixes installed."
"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 provides a checklist answer when using SIEM."
"The UI is clean and easy to use."
"This solution can completely detect and prevent incidents on your network."
"Being able to identify security issues as they occur at near real time and then respond to them as soon as they occur is priceless."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"It can integrate with almost any cybersecurity tool available in the market."
 

Cons

"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."
"The only issues that we have are, one the cost, two the dashboard is not very intuitive, even though you can drill down within the dashboard, we usually have to gather information from other sources to determine locations and if its a false positive."
"In reporting they should have a customizable dashboard due to the fact that C-level people don't like reporting to the IT department. They prefer to have a real-time dashboard. That kind of dashboard needs to have various customizations."
"It'll help if customization was easier."
"There are some false positives."
"The technical support is not very good. I find the process difficult."
"The solution should force customers to integrate with network traffic to see the full benefits of XDR."
"Taking into account that server access credentials are controlled by the tool, some more management-focused actions could be performed from AlienVault."
"This solution could be easier to use. It is hard for some people to understand, and they need to get training and certification just to understand what it's showing them."
"The reporting is mediocre and is something that needs to be improved."
"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... The logger can only hold so much data. If they improved that, that would help."
"AlienVault cannot automatically respond to threats like other SIEM solutions, such as Sentinel and LogRhythm. Most of our clients are far away, so it's often challenging to handle alerts when they come up on our dashboard."
"The GUI needs to improve because it's not user-friendly."
"The log query capability is pretty restrictive and I find myself searching through raw logs via command line more often than the GUI."
"The vulnerability management solution is worse than buying a Nessus Professional license."
"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

"Licensing for Palo Alto Networks Cortex XDR can be costly, especially when it comes to a hundred users. A license is required for each user, and the subscription must be renewed on a yearly basis."
"I feel it is fairly priced."
"The pricing seems fair, and I do like the licensing model. You use wherever they are, and it is elastic."
"I don't have any issues with the pricing. We are satisfied with the price."
"This is an expensive solution."
"It has a yearly renewal."
"This is an expensive solution."
"The cost of Cortex XDR by Palo Alto Networks is $55 to $90 USD per endpoint per month."
"The price for this solution is very good, but since the features do not work the price is expensive."
"The pricing is a good value. The key thing is that for the new product, the licensing of it, is subscription-based and it's based on data. Clients need to be really careful when thinking about that, because odds are they're going to need to put a lot more data into it than what they initially estimate, which is going to drive their subscription costs up."
"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."
"We pay around $12,000 a year including storage."
"Its price is much lower than McAfee ESM."
"Pricing is very competitive with other products and you get much more functionality from AlienVault."
"It is affordable, and it also has many features that the premium products such as ArcSight and QRadar have. It is a very good platform for a SIEM solution. Everything is included in the price."
"It’s a single license platform."
