Fortinet Fortigate Pros and Cons


  • User-friendly VPN
  • Support for various wireless technologies
  • GUI (graphical user interface) is simple and intuitive
  • High performance threat protection


  • Slow technical support
  • Unstable firmware
  • Upgrades can cause compatibility issues

How to use Fortinet Fortigate?

FortiGate FortiOS is available in several models to meet the most demanding threat protection performance requirements, ranging from entry-level hardware to high-end appliances. The unit may operate in one of two modes: Transparent or NAT/Route mode. In Transparent mode, the device is placed between the internal network and the router. Between networks, the unit is used as a gateway or router in NAT/Route mode.

It’s important to choose a high availability (HA) configuration for all FortiGate SPUs (also referred to as a “cluster”). You may create the same settings on a standalone FortiGate using the graphical user interface (GUI). The GUI gives you access to most FortiOS capabilities, including Fortinet Security Fabric, FortiView, networking, system administration, firewall rules and exceptions, security profiles, IPsec VPNs, SSL VPNs, user accounts, and other features.

Our Rating Process

In a nutshell, firewalls are based on the simple idea that network traffic from less secure environments should be authenticated and inspected before moving into a more secure environment. While the concept is straightforward, the added layers of technical requirements and enough acronyms to fill a football stadium can be a deterrent for some companies to implement a network security solution. Fear not—we’ve broken down this Fortinet FortiGate firewall review into bitesize criteria based on performance, value, pricing, and security. Criteria are scored out of 5 points to help you in your next-gen firewall journey.

Performance – 5/5

FortiGate NGFW identifies thousands of applications inside network traffic to prevent and detect known and unknown attacks using continuous threat intelligence. You will be hard-pressed to find a Fortinet firewall review that doesn’t rave about FortiGate’s industry-leading threat protection performance and ultra-low latency.

Value – 5/5

Take a second to scroll down to the product comparison. If the long list of features isn’t enough to prove the value FortiGate has to offer, NSS Labs gave Fortinet a $2 TCO (total cost of ownership) per protected Mbps. For comparison, NNS Labs tested nine other NGFW vendors, some with a TCO as high as $57 per protected Mbps.

Pricing – 5/5

Security-driven networking delivers a high-density, flexible combination of various high-speed interfaces to enable the best TCO for customer deployments. Depending on network and user demands, entry-level hardware appliances start around $500 and can reach $350,000 for high-end enterprise pricing.

Security – 5/5

In a Breach Prevent System Test performed by NSS Labs, Fortinet FortiGate blocked 100% of web-delivered malware as well as drive-by and social exploits. Test results also reported 99.4% of mail-delivered malware was detected and blocked. Fortinet FortiGate received an overall score of 97.8% for security effectiveness.

Frequently Asked Questions

What is a next generation firewall?

A next generation firewall (NGFW) takes a regular firewall and makes it even better thanks to the additional multilayered security features. A traditional firewall will monitor incoming and outgoing network traffic, whereas a next generation firewall will do so while also providing more security elements like application awareness and control, deep packet inspection (DPI), cloud-delivered threat intelligence, sandbox integration and more. If you want a firewall with all the security bells and whistles, NGFW would be the route you want to go.

What is FortiClient?

FortiClient is a security solution that extends the power of FortiGate’s threat protection to endpoints on your network, including desktops, laptops, tablets, and smartphones. FortiClient has no per-seat license fees, eliminating the need to manage multiple endpoints so users and guests can work from anywhere without compromising network security. FortiClient can also be used as a standalone option.

How to disable Fortinet on Android?

To disable Fortinet web security on Android, select Unprotected, then toggle the Enabled switch to Off. To disable web security, toggle the Enabled switch to Off. When FortiGate endpoint control is managing FortiClient, the user cannot enable or disable web security.

To disable Fortinet auto start on Android, select the menu icon, then Settings in the dropdown list. In the FortiClient settings page, select Auto Start, then select Disabled. By default, auto start is enabled.

How much is a network firewall?

Network firewall pricing depends on several factors, including the size of your business, how much traffic the firewall will need to process, how many interfaces traffic will be segmented to, and what forms of traffic inspection will the firewall need to perform. It’s also important to consider the benefits of manual and human-delivered firewall management against the savings and flexibility provided by automation to accurately evaluate the total cost of ownership.
