FortiGate Next-Generation Firewall technology delivers complete content and network protection by combining stateful inspection with a comprehensive suite of powerful security features.
Application control, firewall, antivirus, IPS, Web filtering and VPN along with advanced features such as an extreme threat database, vulnerability management and flow-based inspection work in concert to identify and mitigate the latest complex security threats. The security-hardened FortiOS operating system is purpose-built for inspection and identification of malware and supports direct Single Root I/O Virtualization (SR-IOV) for higher & more consistent performance.
FortiGate firewall for AWS supports "Unicast HA" to allow active/passive HA configurations. When a failure is detected, the passive firewall instance becomes active and utilizes AWS API calls to configure its interfaces/ports.
