Manager, Information Technology Operation/Presales at TechMonarch

A stable solution with an intuitive interface and quick customer service

I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

Perimeter security has reduced botnet attacks and now needs better interface and logging

The best features Arista Edge Threat Management NG Firewall offers are its ability to push a lot of traffic along with bandwidth management and traffic policy. Bandwidth management and traffic policy help my organization by keeping our internet subscription low. Arista Edge Threat Management NG Firewall has positively impacted my organization by reducing botnet attacks. Immediately after I installed the firewall, it stopped a few botnet attacks.

Has streamlined secure deployments across large enterprises while offering reliable protection and intuitive management

The centralized management console, also referred to as the Zscaler dashboard, impacts the ability of my customers to respond to security incidents significantly. I see it as user-friendly, and clients are really happy with using it, which motivates them to keep using Zscaler Cloud Firewall because they enjoy the GUI. It's very intuitive, making it easy to navigate alerts and incidents. My clients rarely have questions about where to find specific information once Zscaler Cloud Firewall is running. The interface speaks for itself, requiring little to no additional training, which is a major plus. Advanced threat protection features in Zscaler Cloud Firewall are practically the key component that every customer wants. Unfortunately, it is an option and not included in the basic package. Clients need to pay for the next higher bundle to access it, but practically all clients I have dealt with want this feature 100%. Regarding visibility, I can confirm that Zscaler Cloud Firewall indeed includes a feature for application layer visibility embedded in the service. It provides visibility into what you're doing, which is especially interesting nowadays when discussing AI tools, as companies do not want their employees to copy-paste sensitive information into AI systems. We have seen cases such as Samsung's chip design where sensitive info got exposed. The visibility of applications, including cloud applications and AI tools, is significant for compliance with data policies, and you can also run reports and alerts on it.

Quotes from Members

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

Pros

"The SD-WAN feature is the most valuable. This feature evolved from link load balancing. It has helped us in terms of our uptime and privatizing applications whenever we experience an outage. The SD-WAN feature has been a plus for us. Two-factor authentication has allowed us to add more users in terms of remote working. We have two-factor authentication for remote workers to authenticate them before they get on the network."

"Fortinet FortiGate has reasonable pricing and is easy to operate; it is efficient and represents the future for security, including cloud security and branch-to-cloud security."

"I like Fortinet FortiGate's antispam filter, SPN, and clustering features."

"The solution is superior to Cisco in terms of security."

"The most valuable features of Fortinet FortiGate are it is one of the most mature firewalls in the UTM bundle."

"In terms of security, we have not experienced any security flaws or loopholes, and it has proven to be quite stable."

"We use the filtering feature the most. It has filtering and inbuilt securities. We can create customized rules to define which users can access a particular type of site. We can create policies inside the firewall."

"The web filtering feature and the intrusion protection system are the most valuable. It is a resilient appliance. I never had an issue with it in terms of any security breaches."

More Fortinet FortiGate pros

"The product's initial setup phase is easy."

"Arista Edge Threat Management NG Firewall has positively impacted my organization by reducing botnet attacks."

"Phish Blocker is a valuable feature."

"The scalability is okay. We have around 2200 people using this solution."

"It provides in-depth visibility into your network, ensuring that traffic flowing into your organization, be it from offices or individual users, is effectively filtered and secured through multiple layers of protection."

"Most of the features that Zscaler has to offer, we will deploy."

"The initial setup is straightforward."

"Includes advanced tech protection."

"The solution offers good sandboxing."

"Zscaler Cloud Firewall understands the applications in the current generation and adapts to the present generation cloud applications."

"Zscaler is still a very good product."

More Zscaler Cloud Firewall pros

Cons

"Fortinet FortiGate could improve by having better visibility. Palo Alto has better visibility."

"Fortinet FortiGate could improve by having more storage in the hardware for log data."

"I think there could be more QoS features"

"FortiOS is not simple."

"It would be ideal if they had some sort of GUI interface for troubleshooting and diagnostics."

"There are just some services that aren't available. For example, the Ethernet or point-to-point protocols. They could add these services to their product offering - especially services for ISPs."

"The only challenge with Fortinet FortiGate is the pricing model."

"A sandbox would be good in order to be able to inspect the emails containing spam and be able to validate the emails that contain malware, prior to delivering to the customer."

More Fortinet FortiGate cons

"The documentation is not clear."

"The product has a lot to improve in the area of policy implementation."

"Arista Edge Threat Management NG Firewall can be improved, particularly the user interface, which is not very good, and also the logs, which are not very good."

"Data Leak Prevention is only for web filtering and there is no protection for email."

"There are some areas it could improve when it comes to blocking, we have to block some things manually. For example, if we block a top-level domain we have seen that the new IPs come through, the IPs are not blocked. There should be some more granular way of doing it. My only request is if you're blocking something at a top level, the sub-level sub-domains and all those other IPs should be blocked too automatically."

"The product could improve its integration with some legacy systems."

"Apart from the issues associated with the product in areas like the DC performance issues and DC failover, Zscaler Cloud Firewall's IP should not have a proxy IP."

"Instead of the standard license, they should certainly provide customers with the visibility to access and view the logs."

"The issue right now is probably that Zscaler is not providing web browser isolation. Another solution, Menlo, offers this. For one customer, we had to send traffic to Menlo to do the isolation for us. It was requested by the customer so that they could integrate any iframe. Zscaler needs to add this type of feature in their next release."

"They do not provide a few components that are fundamental to differentiate the products"

"We are having some issues with internet access being denied when organizational ID-based policies change. For example, a lower level employee ends up getting the same level of access as that of a higher level employee."

More Zscaler Cloud Firewall cons

Pricing and Cost Advice

"Go for long term pricing negotiated at the time of purchase."

"The price is relatively expensive compared to other solutions which are providing similar features."

"Setup cost may be not so low, as you expect, because it depends on different factors, but TCO for 5 years may pleasantly surprise you."

"It's a very full-featured and it's priced well solution."

"The price for the device and software is high. However, the solution is of good quality and has a lot of features."

"Pricing for Fortinet FortiGate SWG is more suitable for enterprise or large-sized organizations because they are the ones who can afford it versus small and medium-sized organizations."

"It is cost-effective, and provides a good value for your money. The pricing, and license renewal, is very reasonable for us."

"The tool is a bit pricey for small businesses, but it is still bearable in terms of cost."

More Fortinet FortiGate pricing and cost advice

"The tool is quite cheap."

"I consider it an averagely-priced tool."

"There are licensing costs, and I would not say that it's a cheap vendor."

"It is expensive for small businesses."

"The licensing is on a yearly basis. It is somewhere around 30 or 40 pounds per user for our organization."

"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing an eight out of ten."

"It is not the most budget-friendly solution, but it's important to consider its overall value."

"The product is a bit expensive compared to the solutions offered by its competitors, like Palo Alto. There is a need to make yearly payments towards the license in charges associated with the product."

"There is an annual license required for the use of the Zscaler Cloud Firewall."

"There are different subscription models available."
