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.

Quotes from Members

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

Pros

"The initial setup is easy."

"Palo Alto is the core of the security infrastructure in the environment."

"The live terminal is probably the best thing ever. It gives you the access to get straight onto any machine."

"The solution is a new generation XDR that has a lot of artificial intelligence modules."

"The anti-exploit is impenetrable."

"It blocks malicious files, prevents attacks, and doesn't require many updates because it is a very light application."

"I recommend this solution to others because it is easy to manage, reliable, and overall good to use."

"Cortex XDR alerts us on the dashboard when there's a threat, which allows us to restrict that user and helps secure our infrastructure."

More Cortex XDR by Palo Alto Networks pros

"The advice I would give to anyone considering WatchGuard Firebox is that it is a good product, despite what they say about it not being in the Gartner quadrant leaders."

"WatchGuard is very user-friendly. It provides us with all of the security services we need."

"Two of the functionalities we use most are the traffic monitoring and the full panel dashboard. Those are two things that are very useful for us... In addition, it provides us with layered security. It allows us to determine what types of access, to which networks, we want to allow or deny."

"The alarm system is valuable."

"I like the High Availability features of the newest ones I'm using because they allow a firewall to fail and still be up and running."

"It does the job of what it says it does. We set it to what we want it to block and then it blocks it."

"It works right out of the box. You just have to enable it and you can start working."

"My favorite aspect is that its security capabilities are very good, with all-in-one security service capabilities including Intrusion Prevention System, IPS, Gateway Antivirus, Application Control, and Web Filtering."

More WatchGuard Firebox pros

"Zscaler Client Connector has eliminated VPN bottlenecks and outages, improved user productivity with instant secure access, and reduced help desk tickets related to VPN issues, overcoming 60% of VPN-related problems while allowing faster onboarding of remote users and better enforcement of zero-trust security policies."

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

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

"Zscaler Client Connector is quite scalable, and I would rate its scalability as nine or ten out of ten."

"The solution operates in the background seamlessly without the user noticing."

"The real-time analytics feature in Zscaler Client Connector is another valuable feature called Digital Experience, or ZDX, which can easily identify the root cause of issues accessing public or internal resources and provide good analysis so relevant teams can quickly resolve them, making it a very good tool that helps customers."

"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."

"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."

Cons

"There are some default policies which sometimes affect our applications and cause them to run around. In the hotel industry, we use a different type of data versus Oracle and SQL. By default, there are some policies which stop us from running properly. Because of this, the support level is also not that strong. We have to wait to get a results."

"The solution should add unwanted malicious hash values to a block list so that whenever the action is triggered, it will automatically prevent the malicious content."

"The solution can never really be an on-premises solution based simply on the way it is set up. It needs metadata to run and improve. Having an on-premises solution would cut it off from making improvements."

"The dashboard could use some significant improvement, just making it more useful with more information. It has a limited amount of information right now. It is customizable, but I'd love to see a better out-of-box dashboard."

"I would rate it an 8 rather than a 10 mainly because there is still room to improve the user experience around complex investigations, including alert tuning and third-party integration."

"I am facing issues with customer support for Cortex XDR by Palo Alto Networks, so I am not satisfied with customer support."

"The price could be a little lower."

"The onboarding process could be better."

More Cortex XDR by Palo Alto Networks cons

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

"The data loss protection works well, but it could be easier to configure."

"The main trouble is the price of the product."

"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."

"There is room for improvement in WatchGuard Firebox regarding customization and AI functionality."

"WatchGuard Gateway AntiVirus is just a firewall."

"The data loss protection works well, but it could be easier to configure. The complexity of data loss protection makes it a more difficult feature to fully leverage. Better integration with third-party, two-factor authentication would be advantageous."

"The user interface and configuration can be improved."

More WatchGuard Firebox cons

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

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

"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."

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

"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."

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

Pricing and Cost Advice

"This is an expensive solution."

"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."

"The price of the solution could be reduced. I have customers that have voiced that the solution is good for the value but if I want to sell more of the solution the price reduction would help."

"Cortex XDR’s pricing is very reasonable."

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

"If one wishes to work with another team or large number of users at a future point, he must purchase a license for them."

"The cost depends on your chosen license type, like Pro or other licenses."

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

More Cortex XDR by Palo Alto Networks pricing and cost advice

"I would rate the pricing at seven out of ten. As for the licensing costs, we typically have yearly licenses for our clients, but there are no additional costs beyond the standard licensing fees."

"I buy a three-year renewal on the main device, which is usually around $3,000 to $4,000. They usually upgrade the device when I do it. You get a big discount when you do three years."

"Firebox is priced reasonably."

"It costs me about $800 a year."

"The pricing of WatchGuard is probably a little higher than the SonicWall, but it makes up for it in dependability. It's worth it to me, especially since it's not much higher. For just a little bit higher price you get the dependability of the firewall with the WatchGuard brand."

"It's fair pricing, but it could always be reduced."

"The solution's most valuable feature is its pricing."

"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."
