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.

Though it helps deal with web traffic or any malicious traffic, it needs to work on its DC performance issues

The product's initial setup phase is moderate in level, so it is neither very complex nor very easy. For the deployment, my company first needs to gather all the requirements of the users and the domain names and consider how many users there are in the company. In the implementation and planning part, my company needs to consider what kind of policies we will create while ensuring that the policies are created based on the requirements of the users. There is a need to segregate the users' requirements since there are separate departments in the company, like the HR department, sales department, IT department, and manufacturing department, so that our company can create policies depending on their requirements. On-site, if you want a GRE tunnel, our company can handle GRE tunnel traffic routing and Zscaler Cloud Firewall, after which Zscaler will take action based on the policies created by our organization. For the deployments and maintenance, a team of five members consisting of two managers and three engineers is required.

Quotes from Members

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

Pros

"Easy to use support and licensing portal as well as activation process."

"The GUI is very simple, and what is very good is that every product, regardless of size, has the same interface."

"The solution is very, very easy to use."

"The initial setup is straightforward."

"FortiGate has led to a reduction in our security budget."

"The most valuable feature is the VDOM, which allows the customer to have multiple firewalls in a single campus."

"It is stable and easy to use. There are a lot of good resources available on the web."

"The usage in general is pretty good."

More Fortinet FortiGate pros

"The app inspection is very helpful for network security."

"The stability of Palo Alto Networks CN-Series is excellent."

"The product’s firewall and VPN package are fantastic compared to any other 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."

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

"If malicious traffic attacks our on-premises servers, then it gets blocked by Zscaler Cloud Firewall."

"Zscaler is still a very good product."

"I like the ease of deployment and its flexibility. We don't need to deal with license, quotes, procurement, delivery, and installation. Everything is software-based, and it's very easy to operate."

"It is a stable solution."

Cons

"Fortinet currently has many products bundled with FortiGate including the basic firewall and load balancer, and I think that that they need to have separate product portfolios for each of these specialized services."

"I would like to see more advanced developments of a wireless controller in the future."

"Tunnel flapping was one of the major things I had seen wherein your internet link remains but your VPN tunnel is down. However, since I got a fix from the TAC team, I have not noticed it, but the customer complained a few times that they couldn't access the internet because of this problem."

"Bandwidth usage in reporting could be improved for Fortinet FortiGate."

"The biggest "gotcha" is that if the client purchases what they call the UTM shared bundle, which has unified threat management on both, it's not as easy to manage if you have more than one firewall."

"Some of the filtering is not robust, you can escape it with a VPN. Some of the users bypass some of the filters. It catches some but it also misses some, that area could be improved. It's functioning reasonably but there's room for improvement in that area."

"Fortinet FortiGate needs to improve the logging and reporting. Additionally, the next-generation application's policies should be improved. When they were released they had bugs."

"I would rate the technical support of Fortinet FortiGate as a five because it is not as strong as Cisco. Additionally, the turnaround time is very high compared to Cisco."

More Fortinet FortiGate cons

"Palo Alto Networks CN-Series could improve on its pricing as it is quite expensive."

"I'd like to see more IOPs features."

"Certain criteria need to be met if you want to scale this solution."

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

"It would be nice to have some sort of a form factor, a physical form factor perhaps, or virtual machine that you could install on devices or on a cloud, and have some cloud computing."

"Its technical support services could be better."

"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"

"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."

Pricing and Cost Advice

"We just pay a flat monthly fee to the vendor for the support."

"If you purchase a one-year subscription with the hardware and then you want to renew for the second year, it is very costly."

"Fortinet FortiGate's price can be reduced."

"It has a competitive price."

"Some of our customers are using Sophos and SonicWall due to price concerns, as they can't manage the pricing of Fortinet FortiGate."

"It scales well if you know what to buy from a physical box standpoint. They seem to offer something for every level."

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

"The price of FortiGate is comparable to that of most other firewall solutions and is more affordable than Cisco."
