Security between networks is implemented in an intermediary device (a router or firewall appliance) at the perimeter of the network. The firewall function performed by this device permits only known, trusted data to access the network.

Firewall act as a security gateway between two networks as trusted and untrusted networks. (VIKRAM SINGH)
A "go-between" acts as an intermediary between two individuals.
Speed, type of connection and security management tools
Telnet and FTP do not require middleware to function, as both are application layer protocols that directly operate over TCP/IP networks. They can connect clients and servers without intermediary software. However, middleware can be used to enhance their functionality, such as adding security features or facilitating communication between different systems.

In the context of mobile networks, a proxy is an intermediary server that acts as a gateway between a user's device and the internet. It processes requests from the device, forwarding them to the appropriate web servers, and then relays the responses back to the device. Proxies can enhance performance through caching, improve security by hiding the user's IP address, and enable content filtering or access control. They are commonly used in mobile networks to optimize data usage and manage bandwidth.
A between-step is an intermediate or intermediary step, stage or process.

Network architectures are classified according to the way they are controlled and the distance between their nodes.
A "go-between" is someone who acts as an intermediary between two or more parties.
