AWS native network services offer vast functionality and inter-connectivity between the cloud and on-premises networks.

Web Filtering:

FortiGate for AWS offers advanced web filtering capabilities, which allow organizations to control and monitor web access. This feature complements AWS's native security services by providing granular control over web traffic (Option B).

OSPF over IPSec:

FortiGate for AWS can establish dynamic routing protocols such as OSPF (Open Shortest Path First) over IPSec tunnels. This capability enhances network routing flexibility and security, which is not natively provided by AWS (Option C).

Secure SD-WAN with Application Visibility:

FortiGate for AWS provides Secure SD-WAN functionality, offering enhanced application visibility and traffic management. This is a significant addition to AWS's networking services, optimizing application performance and security (Option E).

Comparison with Other Options:

Option A (Higher VPN throughput) is not specifically enhanced by FortiGate as compared to AWS native services.

Option D (Advanced dynamic routing) is partially covered under OSPF over IPSec but is not as specific as the other chosen options.
