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.

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.

Client activity has been monitored efficiently through in-depth log analysis and traffic filtering

I use the Zscaler speed test, and it is very nice. We use some logs from Zscaler Client Connector to collect data and see what is happening, such as if there is an interruption or something. There is a specific tunnel version that we have to use because, depending on the internet provider, some of them have lower speed, so we have some issues. This is because of the provider, not from Zscaler. We use Office 365 services and Office applications, and because some connections are slow and they do not have full coverage from the internet provider, we have some issues. If the speed is slow for Zscaler Client Connector connection, then we have issues because if the speed is not good, then Zscaler Client Connector goes down. This may be because they put some policy. Of course, if you use Office 365 services such as Outlook, the minimum bandwidth is 5 megabits and more, so this causes issues if the users do not have a good remote connection. This depends on the companies and the users, so they need to fix it. This is not from us or our company. It is very useful, and the logs are very helpful. When we go to logs, we understand what is happening.

"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."

"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 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."

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

"Threat identification and detection are the most valuable features of this solution."

More Cortex XDR by Palo Alto Networks pros

"Watchguard Firebox is easy to use and easy to configure."

"We experienced that WatchGuard is easy to setup regarding VPN compared to other firewalls of other brands."

"The VPN is very secure and that's of huge importance because we have remote users who depend on it to do their jobs."

"I find WatchGuard Firebox provides very good value, with configuration migration between boxes, more flexible traffic management, best performance, strong security layers and dependencies, protocol-oriented design, rapid deploy for remote configuration, total protection for inbound and outbound traffic with deep understanding of the traffic, powerful DNS security for both network and mobile users, SD-WAN features that manage line quality, extensive exception handling, and a rich set of integrated security services like Access Portal, Application Control, APT Blocker, Botnet Detection, DLP, Gateway AntiVirus, DNSWatch, Geolocation, IntelligentAV, IPS, Reputation Enabled Defense, spamBlocker, Threat Detection and Response, and WebBlocker."

More WatchGuard Firebox pros

"I'd rate the solution nine out of ten."

"It is very important to see what is happening between the user and the applications that we have, and to filter the traffic from outbound traffic and inside traffic."

"It is very useful, and the logs are very helpful; when we go to logs, we understand what is happening."

"The best features of Zscaler Client Connector are that it gives the client a much more transparent experience, as they don't have to worry about connecting to a VPN."

Cons

"On the pricing aspect, Cortex XDR by Palo Alto Networks needs to have a more reasonable rate, particularly for customers in Sri Lanka and Asian countries."

"A little bit more automation would be nice."

"Cortex does not offer an on-premises solution. However, some customers would prefer not to be on the cloud. It would be ideal if it could offer something on-prem as well."

"Cortex XDR by Palo Alto Networks is a strong tool, but it is true that digesting information sometimes makes the tool go a little bit slower."

"Cortex XDR by Palo Alto Networks can improve mobile integration to allow access to the console."

"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."

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

"Limited remote connection."

More Cortex XDR by Palo Alto Networks cons

"The UI and web view aren't nice."

"It's very hard to get information from their website, for exactly what I need to do. Sometimes I end up having to open a lot of support tickets... It's a navigational issue which makes it hard to find what I'm looking for and it's just so broad."

"What could use some significant improvement in WatchGuard Firebox would be its interface and policy management."

"They need to stop the VLAN limitation. They have a VLAN limitation on the size of their boxes; it is the worst thing ever."

"Websense gives you detailed information as far as the source, but this one only gives you very basic information and, on top of that, it's a free version for only a few months and then you have to pay for it."

"Reporting and advanced threat analytics can be improved in WatchGuard Firebox."

"The control software is currently only available for Windows, which can be a little annoying for Linux users."

"A 12-hour power outage... got our batteries."

More WatchGuard Firebox cons

"The stability of Zscaler Client Connector needs improvement, as it often disconnects and reconnects."

"There is a hard learning curve for Zscaler Client Connector; their support isn't the greatest all the time."

"Zscaler Client Connector is not low in cost; it is definitely on the higher side."

"If the speed is slow for Zscaler Client Connector connection, then we have issues because if the speed is not good, then Zscaler Client Connector goes down."

"There is room for improvement regarding the price of Zscaler Client Connector, as it is one of the most expensive solutions available."

"I rate this product nine out of ten because I have seen some minor instability issues after updates and some room for UI improvement for deeper analytics, with instances of major issues after updating the GCC that required rollbacks."

Pricing and Cost Advice

"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."

"It has a yearly renewal."

"I don't like that they have different types of licenses."

"It is present, but when compared to other competitive products, I would say it is not less expensive; however, when all of the other added values are considered, the price is reasonable."

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

"I feel it is fairly priced."

"We pay about $50,000 USD per year for a bundle that includes Cortex XDR."

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

More Cortex XDR by Palo Alto Networks pricing and cost advice

"We don't have any other costs other than the licensing stuff."

"I think the larger firewall packages are much better because a normal firewall is not enough for these times. You need IPS, APT, and all the security features of a firewall that you can buy."

"The licensing contract we have is on a three-year basis. There aren't any costs in addition to the standard licensing fees—usually, every three years, we just purchase or renew the same license and we are okay. Every six years, we completely change the firewall, but that's the usual schema. So after three years, we just renew the licenses for another three years, and then after that particular period of time, we just purchase another firewall equivalent to the ones that we currently use."

"Each one, for the primary unit, was $8,600 and the High Availability unit was $2,000. That's with three years of subscription and support and the Total Security Suite."

"Its cost is okay. It is not too expensive, not too low. I would rate it a nine out of ten in terms of pricing."

"It is an entry-level product, so the price is cheap."

"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."

"The solution is cheap."
