For site-to-site connections, and even for remote access, one of the most common ways to secure the WAN traffic is by using VPN, or that is the virtual private network. Think of it like having a virtual tunnel between your sites. All traffic between the sites will then pass through the virtual tunnel, hence, a virtual private network. You can also add encryption and authentication to a VPN connection so as to keep your data more secure. However, with added security measures, it will add overhead to the network traffic as well.
