Efficient, user-friendly, and affordable

In the past, NSS Labs was utilized to test files and verify the numbers and datasheets. It would be beneficial to have an organization or testing lab that can verify the numbers in our datasheets since changes are frequently made, which can be inconvenient for review. For instance, when comparing different competitors such as Forcepoint, Palo Alto, and Check Point, the throughput or numbers in the datasheet may be lower than the actual numbers. Conversely, Fortinet typically reports very high numbers, but they cannot be replicated in the real world. Therefore, it would be advantageous for them to partner with a neutral testing organization such as NSS Labs to validate these numbers, thus providing more credibility and comfort to everyone regarding the accuracy of the datasheets. 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. This tool shows a lot of promise and is very good. Making it free would help many companies deliver their products in a more efficient and integrated way. It would also be more valuable to include the tool with the firewall package or license instead of having to pay extra for it. Paying extra puts more pressure on small companies to deliver the firewall and complete the configuration, especially if they have hundreds or thousands of policies. It's very painful to move through these policies line by line. The stability has room for improvement. When it comes to Secure SD-WAN, everything is fine. They are going the right way. SD-WAN is very promising. They can provide the SD-WAN solution separately, but they will not take this approach because even the smallest firewall can support the features, so there is no need to have a separate service or appliance. They are following the right steps, and there is nothing to be improved. Feature-wise, I'm really satisfied with the new release, and the features they have added. For now, it's fine.

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 ease of use."

"The CLI and GUI do a good job of putting a lot at your fingertips."

"The reporting and monitoring are very good."

"Easy to implement, and it is also reliable."

"This version is stable. I don't have any issues with this solution, in our environment, it works well."

"The wireless control is helpful."

"All of the features of Fortinet FortiGate are useful and the security protection is good."

"It has very easy management and an amazing ETM configuration."

More Fortinet FortiGate pros

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

"The technical support from Zscaler was excellent."

"Includes advanced tech protection."

"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."

"The visibility and log availability offered are highly valued for troubleshooting purposes, and this is a key factor driving customer interest in the firewall module."

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

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

"The solution is scalable."

More Zscaler Cloud Firewall pros

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

"The solution can scale well."

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

Cons

"Fortinet FortiGate is a firewall solution and once it's deployed, you can rest assured that your system is secure."

"In the balance between links feature normally you can just choose one option to balance. It would be better for the solution to have more than one option, preferably three."

"Some of the features in the graphical user interface do not work, which requires that we used the command-line-interface."

"They sometimes hide some features and if you want to enable them, you have to go in the CLI, enable the feature and configure it through the CLI. Customers, typically, like everything to be done by the GUI."

"When we cluster the two Fortinet FortiGate boxes together we have some issues."

"In my opinion, Fortinet FortiGate could be improved by making the appliance smaller than what we have here, as it is pretty big."

"I think there could be more QoS features"

"The only issue that I have is with FortiNAC. The firewall is fine, but the FortiNAC interface is a little bit too jumbled or too complicated, not as straightforward as it is on the Fortinet FortiGate firewall and FortiAnalyzer."

More Fortinet FortiGate cons

"I don't have the visibility of a control dashboard or a network management system."

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

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

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

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

"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."

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

"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."

More Zscaler Cloud Firewall cons

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

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

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

Pricing and Cost Advice

"If you compare Fortinet FortiGate with Sophos and other firewall products available in the market, this solution is affordable."

"It is expensive. You need to pay for the subscription every year, which is very expensive. The subscription includes technical support and hardware exchange in case of failure."

"Fortinet has more device options that are affordable for small businesses than Palo Alto, and its enterprise-level models are also cheaper. Palo Alto also has a separate license for VPN connections and SD-WAN, but FortiGate offers these features standard."

"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."

"The pricing of the solution is very competitive."

"In the Asian economy in which we operate, FortiGate is expensive."

"FortiGate's pricing falls within the mid-range when compared to other leading firewall solutions."

"If the customer is looking for SD-WAN, it comes free with FortiGate."

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."

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

"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."

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

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

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

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."
