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.

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.

It Manager at Diamond Braces

A robust appliance that is reasonably priced and straightforward to set up

Although manageable, the user interface is a little bit slow and could be improved. There are two user interface options available, namely the basic and the advanced. The basic UI is not very good and doesn't have a lot of features, although it is fast. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists. At one of our sites, the CPU utilization was very high, and for no reason. Technical support needs to be more responsive to requests.

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

"Fortinet FortiGate is a stable solution."

"Good performance, stability, and virtual domain ability."

"Fortinet FortiGate positively provides my clients' organizations with a high return on investment."

"One of the valuable features is a standardized OS."

"The primary feature I appreciate about Fortinet FortiGate is the ease of setup."

"It is a one box solution, which covers most of the edge device’s requirements."

"Overall, the pricing of the solution is very good. The product offers good value."

More Fortinet FortiGate pros

"It helps a lot of companies to reduce their downtime. Also, It helps businesses in terms of being secured and protected from any threats."

"Zscaler is still a very good product."

"Includes advanced tech protection."

"Since it is really customizable, I can use it and avoid enabling access to the full network."

"Zscaler provides effective protection against various cyber threats ensuring a safe environment"

"The solution offers good sandboxing."

"The initial setup is straightforward."

"The technical support from Zscaler was excellent."

More Zscaler Cloud Firewall pros

"The solution can scale well."

"This is a capable appliance and the standard features work well for us."

"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."

Cons

"It is somewhat expensive compared to other solutions such as Sophos."

"We would like to see better pricing."

"The solution could be improved by addressing limited local reporting. It requires obtaining the FortiAnalyzer for proper visibility because you can't do much from a reporting perspective with just the firewall alone."

"The built-in logging and reporting is limited without FortiAnalyzer."

"Though the tool's GUI is user-friendly, it can be considered as an area with certain shortcomings where improvements are required."

"Monitoring and reporting could be better."

"For the migration, everyone has a firewall in use and I am selling Fortinet. Typically, I am replacing another firewall. Previously, there was a tool available to convert configurations from one firewall, such as Palo Alto, to Fortinet, but this tool is no longer free. If it could be made free again, it would be very beneficial."

"It is stable, but its stability can be improved."

More Fortinet FortiGate cons

"It would be better if they improved their policy, package visibility, and flexibility while we're creating rules for inspection. It could also be cheaper or more things could be included in the basic package. In the next release, I would like better coverage in the Asia Pacific region and better quality of service."

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

"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."

"Zscaler Cloud Firewall should have a better understanding of all dynamic cloud applications."

"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."

"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."

More Zscaler Cloud Firewall cons

"Although manageable, the user interface is a little bit slow and could be improved."

"The product has some scalability and data management issues where improvements are required."

"Sometimes it reboots when you least expect it, and that's the main issue."

Pricing and Cost Advice

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

"Fortinet FortiGate gives you most of the features in one license."

"It's one of the more expensive brands. The 100 series costs around $4,000. They are similar in pricing to what you might get from Cisco solutions and probably other similar ones. They're not more expensive than other similar solutions, but they're certainly not cheaper either."

"For the performance that we get, the price is reasonable. There are cheaper options, but they may not deliver the same kind of performance that we want. For the performance they provide, the price is acceptable."

"You need to pay a license for this solution. Our licensing is now done in our subsidiary."

"Licensing for Fortinet FortiGate is on a yearly basis. Pricing for it is a bit high. It could be cheaper."

"Before choosing a piece of equipment you have to take into account the cost-benefit offered by each one. Sometimes it is not worth paying a very cheap price to have a minimum level of security."

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

More Fortinet FortiGate pricing and cost advice

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

"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."

"It comes at a significantly reduced cost while ensuring control and effectiveness."

"Zscaler is priced too high compared to the cost of Fortinet."

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

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

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

"There are different subscription models available."

More Zscaler Cloud Firewall pricing and cost advice

"This gateway is pretty cheap."

"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
