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.

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.

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 product's initial setup phase is very easy."

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

"My advice for others looking into using Cortex is that it is very easy to use and very useful for the customer environment, whether it's a public or private one."

"I like that the product has behavior-based detection which offers many benefits over signature-based detection."

"From the Palo Alto side, whatever they buy, they integrate that really well into their integration suite, and that makes a massive difference."

"It collects and caches and the knowledge of machine learning from different customers to take to the cloud, it makes it better to use for everybody, it allows for quick learning and updates and can, therefore, offer zero-day malware security, and this sharing of metadata helps make the solution very safe."

"The most valuable features of this product are the management capabilities, which allow an IT organization to get quite a good picture of attempted cyber attacks, and its out-of-the-box investigation capabilities."

"Once you become familiar with it, Cortex XDR by Palo Alto Networks is a more powerful tool and I would say that I prefer it over MDE because it is a stronger tool for me."

More Cortex XDR by Palo Alto Networks pros

"It's pretty simple to use. It's pretty simple to understand, and there's plenty of documentation. It does a pretty good job of what it is meant to do."

"The GUI is easy and intuitive."

"Hands down, it's one of the best firewalls I have ever worked with."

"Management and visibility are the most valuable features."

"WatchGuard Firebox offers a satisfying VM and hardware"

"WatchGuard Firebox simplifies my job through the policies we can define, and when we create a policy, it simplifies our workflow, which helps with our overall efficiency."

"The interface is very good."

"The firewall aspect and the branch office VPNs are the most valuable features... We don't have any issues with it. We don't have to spend a lot of time maintaining it."

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."

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

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

"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."

"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."

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

Cons

"The deployment is pretty hard."

"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."

"The main issue I could point out is the offline agents and the way that it is missing."

"It automatically detects security issues. It should be able to protect our network devices while operating autonomously."

"It tends to do 99.9% of things. The only thing I'd like is single sign-on authentication into their cloud platform so that my users can be properly authenticated against it."

"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."

"A potential area of improvement for Cortex XDR by Palo Alto Networks is the cost."

"It's more focused on network communication. If a customer wants to increase the level of protection and start working with documents, it's impossible to integrate these features into the system. It's more of a communication-oriented system than a content security-oriented system."

More Cortex XDR by Palo Alto Networks cons

"Multi properties could be added to the solution in the future to make it better."

"I don't think I can get a full-blown DNS client from it. I've been trying to have DNS services. It has forwarding, but I don't get the services of a full DNS client. My main difficulty with it is that I can't run a complete service. I need NTP. I need DNS. I need DHCP for my domain, but I only get forwarding. As far as I can tell, I don't get caching and the kinds of reporting and registration needed to host a DNS for a domain. I have to have a separate solution for that."

"While the management of interfaces is straightforward, certain advanced configurations can become complex in large deployments, as it mainly targets small to mid-cap industries."

"The only downside is that it is missing an API, that you can use to easily collect information from it."

"The software in it could be a bit more friendly for an amateur user. I look at it and don't understand what half the stuff is. Looking at the interface, it is all mumbo-jumbo to me. It's not a simple interface. You have to be an IT guy to understand it. It is not for your average person to use, then walk away from it. It is much more entailed."

"The user interface for WatchGuard Firebox has room for improvement. Right now, it's a bit complex to work with and could be easier."

"The few issues that we have had, such as not knowing where to go, they have been answered quickly."

"What could use some significant improvement in WatchGuard Firebox would be its interface and policy management. An additional feature I'd like to see in the next release of WatchGuard Firebox is the ability to modify an existing policy instead of having to recreate a policy when changes are necessary. At the moment, there's no possibility to modify the policy. You have to delete the policy and recreate it."

More WatchGuard Firebox cons

"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."

"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."

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

"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."

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

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."

"The pricing is okay, although direct support can be expensive."

"This is an expensive solution."

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

"Cortex XDR by Palo Alto Networks is quite an expensive solution."

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

"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 solution is expensive. It's pricing is on a yearly-basis."

More Cortex XDR by Palo Alto Networks pricing and cost advice

"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."

"We license the WatchGuard Firebox annually. There are different types of subscriptions available. We are paying approximately $15,000 annually. The cost can increase if you purchase different subscriptions."

"The price of the solution is not expensive, it is less than FortiGate."

"The subscription that was purchased is for three years, but it is usually for one year at a time."

"Cheap."

"The price is very good."

"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."

"The solution is a bit more expensive than other options."
