Enables customers to manage security effortlessly with intuitive features and easy integration

In terms of improvements for Fortinet FortiGate, they could offer evaluation licenses, as compared to Meraki, which provides a 90-day evaluation. In Fortinet FortiGate, they do not provide standard evaluation licenses; instead, we need to request them from the OEM through the account manager for POCs. If we want to conduct a demo, we need to work with real hardware. In comparison to Cisco, we have DCloud, which helps with providing demos to customers, but in Meraki, I need to reach out to them, book a lab, and they need to provide all the hardware. I need remote access and L3 engineers to program it; only then can I offer a real-time demo to the customer.

Abhishek Saini

Professional Services Engineer at Nex7 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.

IT Support Admin at Kuehne & Nagel Inc.

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

"If you are looking for a lifestyle solution, then FortiGate is my choice."

"Fortinet has got great firewalls; they do everything, from FortiTokens for two-factor to IPsec VPNs and SSL VPNs, with a great GUI that makes it easy to use while the support is great."

"The most valuable features of Fortinet FortiGate are the APIs. They are the most widely known."

"Overall, I am satisfied with the product."

"The most useful features of Fortinet FortiGate IPS are you can create a virtual firewall within it, most other firewalls do not have this feature, you are able to manage your network and have network segmentation within your firewall, and additionally, you can create virtual switches within the firewall and have policy management, such as firewall and access policy."

"The solution is very easy to understand. It's not overly complex."

"I have found most of the features to be good with excellent functionality."

"The solution is very stable; it doesn't have bugs or glitches, it doesn't crash or freeze, and it's reliable."

More Fortinet FortiGate pros

"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 hard to pick one feature over another. But if I had to pick one, the UTM would be the most valuable because of the notification. I get notified via email if there is any type of threat detection or alert, telling me something is wrong."

"The interface is very good."

"I recommend Firebox since this device will not let anyone down."

"Simple to move settings between WatchGuard boxes."

"I like WatchGuard's network segmentation features. It's easy to configure user policies."

"Firebox is 10 out of 10 at what it does."

"It is a scalable solution."

More WatchGuard Firebox pros

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

"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."

"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 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."

"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."

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

"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

"The people we are working with are not able to configure MFA. They are having some technical issues. Fortinet needs to ensure that its partners are well-trained."

"Its technical support could be better."

"In the future, I would like to see improvements made to cloud-based management."

"The SD-WAN functionality is a bit overly complicated and not fully documented."

"Overall it is not scalable."

"The advanced models are expensive."

"We had some issues in the beginning while setting it up, but after doing the firmware update, it is working fine."

"While the security is good, we'd always prefer if it was even better to ensure protection."

More Fortinet FortiGate cons

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

"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."

"In general, I would rate WatchGuard Firebox around 6-7; it is a good firewall, but they lack good administration tools. We experience many problems with the performance and administration tools on the web, including several issues with VPNs."

"The product's technical support services need improvement."

"The level of support from WatchGuard is not as good."

"The solution needs to improve the interface. I'm not able to easily find things using it."

"The solution can improve by adding a feature to tag a MAC address of a computer system in the policy and more IP configuration settings."

"Proxy actions can be a little bit complicated."

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."

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

"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

"It was pretty affordable. We did go a little bit above MSRP, but the service pack that was included was quite worth the additional costs. It is competitively priced compared to other major players in the market. It is significantly cheaper than Check Point, which is a primary competitor. Additionally, its pricing is comparable to that of Cisco's ASA and a few other vendors."

"It is not a very costly product if you compare it with other products. The return on investment is also good. If you compare the return of investment and money that you are spending on this product with Palo Alto, Cisco, Check Point, and other solutions, the investment is very less. We are happy with this solution. The optional licenses are there, and you can choose which one you want and which one to avoid."

"It's very competitive."

"Pricing is good. They offer a lot of things, the most important is the support. Every time you upgrade your license, you also get insurance for the equipment. If you have any problem with equipment, they send in new equipment."

"It is a good product from a price perspective versus functionality."

"The license is too expensive to renew. The license renewal process is also complex."

"Its price is reasonable. They have a clear pricing policy. It is not complicated by the number of VPN users at a time. We know what the price is. The yearly subscription for the security license is rather high, but it is all included for whatever number of users you have and the kind of functions you need."

"In my opinion, the pricing of the product is reasonable."

More Fortinet FortiGate pricing and cost advice

"There is a license required to use the solution and we pay annually. The price could be reduced because it is a bit expensive."

"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."

"WatchGuard offers competitive pricing with attractive margins, benefiting both the company and its partners."

"The licensing model for WatchGuard Application Control is based on the number of users. WatchGuard Application Control also has licensing models with several features."

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

"We pay about $3,500 every three years."

"The two larger devices are about $1,000 each and the smaller ones are about $500 or $600 each... It's cheaper and you have more control because it's self-managed."

"I think the tool is quite competitive compared to the other brands."
