Hello.

There is a way to encrypt DirectConnect communication using Site to Site VPN.  
With this setting, no settings are required on the client application side.

> This solution combines the benefits of the end-to-end secure IPsec connection with low latency and increased bandwidth of the AWS Direct Connect to provide a more consistent network experience than internet-based VPN connections. A BGP connection session is established between AWS Direct Connect and your router on the public VIF. Another BGP session or a static route will be established between the virtual private gateway and your router on the IPsec VPN tunnels.
