I want to build commercial server on ( c++ or c run on windows and Linux ) with maximum security possible , that send/receive data to the client ( html + java script vanilla )

What I have tried:

Library :
1- Websocket server ( wss ) : https://github.com/uNetworking/uWebSockets
2- Authentication ( OAuth 2.0 ) : https://github.com/Microsoft/cpprestsdk

My plan is to use the the 2nd library for authentication only and the 1st as websocket server ( because of the performance & lightweight ) .
and using this as example : "C++ REST SDK OAuth 2.0 server" on www.cookinapps.io


My question is
Is this solution is the best or there are other options or libraries with better security & performance on the same platform
