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.

We have improved network security with user-friendly controls and high threat intelligence

FortiOS is very user-friendly and easy to configure for L1, L2, and L3 personnel. Its web filtering, application control, and IPS features are very user-friendly, easy to manage, and deploy. The threat intelligence in FortiOS is very high, and the system is scalable without additional licensing costs. FortiOS allows us to expand the number of users and devices as our network needs grow.

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.

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

Pros

"We have found it to be very reliable and that's why our teams and various users in our company use it as our main firewall every day."

"Mainly the FortiGate reporting system is very good. It guides us through all the expectations of security. Fortinet provides us all that we need for security. Also, Fortinet FortiGate is a next-generation firewall. It is much more advanced than others."

"The Fortinet FortiGate local partners were good. I did not have direct contact with Fortinet support."

"The wireless control is helpful."

"It's very good and very stable for businesses. It works very well."

"The email protection and VPN features are the most valuable."

"The most valuable feature is the interface, which is very user friendly. We are utilizing most of the features, like content filtering. The firewall is powerful."

"I really like the captive portal feature for our guest network. It has nice VLAN features in terms of separating our network. The anti-virus is also good."

More Fortinet FortiGate pros

"The most valuable features are the ease of use, and the overall simplicity, everyone can use it with a small introduction."

"All of the features in this solution are effective and efficient."

"Overall, I would rate FortiOS at least a nine out of ten."

"The information security features are the most valuable."

"The solution is very easy to configure and has a good interface, plus it offers more configuration options than other vendors."

"In terms of benefits, it’s a standard solution used by many, and our customers and partners widely utilize the VPN features. It’s elementary to work with and implement because it is familiar across different infrastructures."

"The pricing is excellent."

More Fortinet FortiOS 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."

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

More Zscaler Cloud Firewall pros

Cons

"I would like some automated custom reporting."

"It would be nice if backups could more easily migrate between different models."

"In the next release, maybe the documentation on how to use this solution could be improved."

"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."

"There are some cloud-based features that could be much more flexible than they currently are."

"The command line is complicated, and the interface could be better."

"The customization could be improved. Cisco, for example, is much better at this. They need to work to be at least as good as they are."

"FortiGate can improve its token system, as it requires a purchase before use."

More Fortinet FortiGate cons

"The reporting for this solution could be improved. It could also be more stable and offer better pricing."

"I would like to see more statistics in the monitoring part."

"The signature discs, compared to Palo Alto, aren't as good. It takes more time to get the signature updates."

"A switch should be introduced."

"Fortinet FortiOS could improve by having better authentication methods with Microsoft or Google Services."

"The pricing model makes this product far more expensive than similar solutions."

"The product needs a feature that allows users to create another site on a VPN."

"The technical support is good. However, during the holidays they can get a little slow to respond."

More Fortinet FortiOS cons

"There are several areas for improvement. Firstly, the GUI is outdated, with noticeable lags and delays, especially when generating reports for past transactions."

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

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

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

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

"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."

"When it comes to customer support, there is room for improvement in Zscaler's service."

"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."

More Zscaler Cloud Firewall cons

Pricing and Cost Advice

"The pricing is perfect."

"A year or two years back, its price was competitive and reasonable. That was one of the reasons that people easily switched to Fortinet. Over the last two years, the prices have increased drastically. However, the prices of others have also increased. An advantage is there from the price point but not as much as it was previously."

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

"Fortigate's pricing is competitive."

"I think the price of Fortinet FortiGate is very reasonable."

"The price of FortiGate is good."

"The Indian market is different than the European and American markets. When you compare they need to be a bit more aggressive on pricing."

More Fortinet FortiGate pricing and cost advice

"The pricing could always be lower."

"We had a three-year license to use Fortinet FortiOS and we are going to renew it this year."
