Easy to manage with good web filtering and good security

Reliable management with user-friendly features and straightforward deployment

Pros

"It is user-friendly when it comes to turning on features, and it has been reliable and effective."

Cons

"There should be more documentation on how to use the CLI or how to perform CLI versions of tasks that can be done through the GUI."

Product version discussed: 7.4.7.12
Provides effective filtering features, good stability but initial setup is moderately challenging

Pros

"I find filtering traffic, filtering web traffic, session traffic, and managing the network as valuable features. "

Cons

"There is room for improvement in the reporting part. The reporting is only for logging data, and it's just a tabulation of the log in the report. I would like to be able to take down more information in the event of an incident."

Security features have improved protection with reliable updates and support

Pros

"Fortinet delivers a good balance of price and performance."

Cons

"Stability is a seven out of ten because during version migrations, and sometimes with new versions, Fortinet is not as good. Palo Alto is more stable than Fortinet, but this depends on the configuration."

Useful for site-to-site VPNs, reporting features, and wireless capabilities

Pros

"We primarily use Fortinet FortiOS for site-to-site VPNs, reporting features, and wireless capabilities. It is well integrated within the Fortinet ecosystem. "

Cons

"The main challenge with Fortinet FortiOS is integration with third-party solutions. I don't see any other areas for improvement. Nowadays, all products work well for 50-60 percent of needs. We must only fulfill 60-70 percent of client requirements because they don't use 100 percent of product features. Banks and financial sectors might need more security features. I don't work much in banking, but they often use multiple products for different security layers, not just firewalls. They might use various products or APIs for different purposes. In the end, clients use the products that suit their needs. "

Pros

"The technical support on offer has always been quite good."

Cons

"The pricing of the product is too high. "
