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.

Professional Services Engineer at Next7 IT

Centralized security management has improved VPN reliability and simplified daily operations

WatchGuard Firebox is a strong and reliable platform overall, but there are a few areas where improvements could make the experience even better. One area is the user interface and navigation in some management tools. While the platform is powerful, certain configurations and troubleshooting workflows can feel less intuitive compared to some newer cloud-native firewall platforms. Another point is reporting and log analysis. Although the logging features are very useful, deeper analytics and more customizable reporting dashboards would make security monitoring much more effective. Firmware upgrades and policy synchronization can sometimes require careful planning to avoid security interruptions. Overall, the core security and VPN functionality are very solid, but improving usability, reporting, and automation would make the platform even stronger. One area that could be improved is the learning curve for new administrators. While experienced engineers can work with the platform effectively, some advanced networking and security configurations can be a bit complex for junior technicians. More guided configuration workflows, smarter recommendations, and simplified troubleshooting tools would make onboarding easier. Another improvement would be more flexible reporting customization for executive-level and client-facing reports.

Quotes from Members

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

Pros

"Cortex is the best tool for endpoint detection, and I have used it to verify hashes or domains to identify malicious activity, trigger playbooks that automate and gather endpoint logs, block malicious processes, and update incident tickets, showcasing end-to-end processes with automation in investigation and reducing the analysis workflow."

"The solution's most valuable feature is the user interface."

"My advice for anybody who is considering Cortex XDR is that it is a complete solution, and has very good features."

"We think that this product will help us grow, as it meets our needs currently and we can grow with it over time."

"Cortex XDR is stable, offering high quality and reliable performance."

"Traps pays for itself within the first 16 months of a three-year subscription."

"It can automatically correlate events and logs, which is very helpful for an IT administrator. It can correlate different kinds of malware activities over a network, agent, or host system. You do not need to do it manually. It is a good feature. It is also a user-friendly solution. We have deployed it on the cloud because our space does not provide any flexibility for on-premises deployment, but Palo Alto has added some flexibility to install it on-premises. It must be like the same Cortex XDR agent for all the VPN services, web filtering services, and everything else."

"Stability is a primary factor, and then there's the ease of distribution and policy management; Cortex XDR by Palo Alto Networks is very easy to work with, and we're quite happy with them."

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."

"One of my favorite features is the Geolocation service, where you can actually block specific activity or IP addresses registered to certain countries. For example, I don't want any web traffic from Russia or North Korea. I may even lock down certain policies down to 'I only want U.S. IP addresses.' I find that very useful."

"It just works and I may have to reboot it once every two or three years."

"The most valuable feature of WatchGuard Firebox is its ease of use."

"The most valuable features of this solution are live logging, rule setup and maintenance, and VPN creation."

"It's pretty simple to understand when you want to do any diagnostics on your network. If you want to go in and see what packages are having trouble getting through, what's being held, stalled, etc., it's very easy to use in that way."

"[A] valuable feature would be the branch office. We have five offices throughout the United States, and it coordinates the connections of those offices."

"The technical support is very fast - when we raise an incident, we get a solution in no time."

"WatchGuard Firebox made it so that I can connect to my remote offices without having to set up every computer to connect to our headquarters."

More WatchGuard Firebox pros

Cons

"Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth."

"I don't like that they have different types of licenses. For example, if users select a license, they think they will have all the platforms they need to improve their network or security. But after some time, Palo Alto Networks changed their licensing, and some of the features that, for example, were free at the beginning now have a cost. I think the integration can be improved. For example, a lot of tools are just integrated through APIs."

"I have run into some detection issues with Cortex XDR. It needs to be better at detection of internal attacks."

"While using Cortex, I noticed some aspects that could be improved, such as increasing the synchronization speed between XDR and Xnor."

"We had a problem with getting our older endpoints up to date, but their newest updates have been really good. I've been pleased with it in terms of what our needs are. It's doing what we want it to do."

"Enhancing UI simplicity and playbook flexibility are areas that could benefit from more low-code automation options for smoother integrations."

"Cortex XDR by Palo Alto Networks is not only pricey; it is extremely expensive."

"It takes time to scan the servers and devices."

More Cortex XDR by Palo Alto Networks cons

"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."

"The major problem is pricing and licensing loss. In India, the cost for renewal after three years is 75% of the hardware cost, which is a significant problem."

"An area for improvement is that when we use a web administration link, there is no security."

"WatchGuard should offer more visibility into user activity. For example, we should have more details when WatchGuard denies a user access to a port."

"The way Secure Sign-On authentication is happening needs to be improved. When the Secure Sign-On portal is turned on, anybody who comes into the campus, whether he or she is a staff member or a guest, has to go past the initial portal. One of the shortcomings is the username. It shouldn't allow permutations or combinations with upper or lower cases. For example, when there is a username abc, it shouldn't allow ABC or Abc. It should not allow the same username, but currently, two separate people can go in. Therefore, its authentication or validation should be improved, and the case sensitiveness should be picked up. If I have restricted someone to two devices, they shouldn't be able to use different combinations of the same username and get into the third or fourth device. It shouldn't allow different combinations of alphabets to be used to log in."

"WatchGuard Gateway AntiVirus is just a firewall."

"It would be wonderful if the WatchGuard team develops nice products for threat intelligence."

"The website must provide more information on the product."

"The pricing of WatchGuard Threat Detection and Response could be improved."

More WatchGuard Firebox cons

Pricing and Cost Advice

"We didn't have to pay any additional fee for the cloud instance. It just came with the renewal, which was nice."

"The solution has one subscription for endpoint protection and one subscription for detection and response. The two licenses combined give you the BRO version."

"The pricing is a little bit on the expensive side."

"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."

"This is an expensive solution."

"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."

"The pricing is a little high. It is per user per year."

"The cost of Cortex XDR by Palo Alto Networks is $55 to $90 USD per endpoint per month."

More Cortex XDR by Palo Alto Networks pricing and cost advice

"It’s a single license platform."

"I spent $600 or $800 on this product and I'm paying a couple of hundred dollars a year in a subscription service to keep the lights on, on it... It works out to $100 or $200 a year if you buy several years at once. It's fair."

"WatchGuard Firebox is a cheap solution."

"They have an annual subscription license. Initially, we had opted for three years. After that, we went for another three years, and after that, we have been doing it yearly. They also have a license for five years."

"The pricing is competitive."

"WatchGuard Firebox has good quality, but it is expensive."

"Very competitive pricing regarding throughput compared to other alternatives."

"The solution is cheap."

"It has a very good price. It is not the most expensive one, and it is also not the cheapest one. It is just spot-on in terms of price."
