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 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."

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

"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."

"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."

"Cortex XDR is a very capable solution for protecting large networks and a lot of endpoints. It's very useful because the automation is very high, and if you combine it with the features on Palo Alto firewalls, it provides very strong protection."

"Cortex XDR by Palo Alto Networks should be a stable solution."

"When the pandemic started, Palo Alto came up with many solutions, which helped with the quick shift from on-premises to the cloud."

"Cortex XDR by Palo Alto Networks has changed the way my security team detects, investigates, and responds to threats, as we are able to see the files, unwanted files, unsecured files, and unauthorized files, so we are quarantining them."

More Cortex XDR by Palo Alto Networks pros

"We use the on-premises deployment model. It's a great product."

"The most valuable feature is the ease of use of the interface."

"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."

"Overall, I value the platform because it combines multiple layers of security, centralized management, and strong network performance into a single solution, making it easier to maintain both protection and operations."

"The solution simplifies my business. Normally, for administration, we are using NetApp System Manager on Window since it's easy to create new policies. In a short amount of time, you can create new policies based on new requirements. For example, in the last few months, many requirements changed due to the coronavirus, adding the use of new services, like Office 365, and eLearning tools, like Zoom."

"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."

"Our opinion of it is that it flat-out works and we're very satisfied with it."

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

More WatchGuard Firebox pros

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

"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."

"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."

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

"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."

Cons

"The solution could improve by providing better integration with their own products and others."

"I would like to see some additional features related to email protection included."

"The MAC agent is not as robust feature-wise as the PC version."

"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 price could be a little lower."

"We have found that there are times Cortex XDR by Palo Alto Networks does not detect some of the viruses, we have to use another protection solution called Kaspersky."

"It's very time-consuming to log support issues and the people that answer the tickets aren't very knowledgeable."

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

More Cortex XDR by Palo Alto Networks cons

"The CLI could be improved in WatchGuard Firebox, and I think integration with a cloud solution—such as Microsoft Enterprise and Google Cloud—has room for improvement."

"In terms of usefulness and reducing frustration, at my level, it's a three."

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

"In terms of what could be improved, I would say their web blocker feature. It is still quite a confusing setup, especially when you want to filter out a particular category for granularity. For example, you do not want to filter Facebook but you do want to filter Facebook games only. It can be done, but the process to do it is very confusing."

"The solution needs to improve its accessibility."

"Reporting is something you've got to set up separately. It's not great. It's okay."

"There could also be better reporting. For example, there should be more out-of-the-box management reports."

"There is no message displayed for the user on the desktop informing them that access to a web page has been blocked by Application Control."

More WatchGuard Firebox cons

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

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

"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 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."

"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."

Pricing and Cost Advice

"Every customer has to pay for a license because it doesn't work with what you get from a managed services provider."

"This is an expensive solution."

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

"It has a yearly renewal."

"Its pricing is kind of in line with its competitors and everybody else out there."

"Very costly product."

"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's way too expensive, but security is expensive. You pay for your licensing, and then you pay for someone to monitor the stuff."

More Cortex XDR by Palo Alto Networks pricing and cost advice

"I haven't seen the pricing since 2017, but it was competitive. SonicWall, Barracuda, and WatchGuard were all about the same price when we did our last pricing."

"The licensing costs are comparatively lower than other providers, and I would rate the pricing as five out of five."

"As per my knowledge, the product is more affordable than alternatives."

"The primary reason that we went with Firebox was its cost. It is very economical and it provided us with all the security functions that we were looking for at the time. And the throughput was more than what we required, so it was a very cost-effective device to deploy on our network."

"Firebox is priced reasonably."

"The licensing can be a one-time purchase unless you need the extra services for example twenty-four seven support."

"It's in the medium range. Its price is pretty good considering the functions and add-ons that are used."

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