The device that a company would place at the edge of its network to view and control which Internet applications are being used is a Proxy Server.
A proxy server acts as an intermediary between a client and a server, intercepting requests from the client and forwarding them on to the server. In this case, the client would be a user on the company's network accessing the Internet, and the server would be the destination of the user's Internet traffic.
By placing a proxy server at the edge of its network, the company can view and control which Internet applications are being used by its users. The proxy server can inspect the contents of the requests and responses passing through it, and can apply policies to allow or block certain applications or types of traffic. For example, the company might want to allow access to certain websites or applications for business purposes, but block access to social media or file sharing sites.
The other options listed are also network security devices, but they would not be the best choice for this particular scenario:
A VPN concentrator is used to manage and secure remote access to a company's network over the Internet. While it can provide secure access to the company's network, it does not provide visibility into which Internet applications are being used.
An NGFW (Next Generation Firewall) is a type of firewall that provides more advanced security features than traditional firewalls, such as intrusion prevention and application-level controls. While it can provide some application-level controls, it does not provide the same level of visibility into Internet applications as a proxy server.
An IDS/IPS (Intrusion Detection System/Intrusion Prevention System) is used to detect and prevent unauthorized access to a company's network. While it can provide some visibility into network traffic, it is not specifically designed to control which Internet applications are being used.
Therefore, the best choice for a company that wants to view and control which Internet applications are being used is a Proxy Server.
