Layer 7 of The OSI Model: Application Layer is the OSI layer closest to the end user, which means that both the OSI application layer and the user interact directly with the software application. This layer interacts with software applications that implement a communicating component.

Is TLS layer 4 or layer 5?

Because TLS operates at Layers 4 through 7 of the OSI model, as opposed to Layer 3, which is the case with IPsec, each application and each communication flow between client and server must establish its own TLS session to gain authentication and data encryption benefits.

Is VPN a Layer 7?

Unlike traditional IP Security (IPSec)-based VPNs, which operate at Layer 3 (the network layer) of the Open Systems Interconnection model, application-layer VPNs operate at Layer 7 (the application layer).

Is firewall a Layer 7?

A layer 7 firewall, as the name suggests, is a type of firewall that operates on the OSI model's 7 layers. The seventh layer of the OSI model, often known as the application layer, allows for more advanced traffic-filtering rules.
