What is vpnui.exe?

cisco-anyconnect-exe is the executable for the Cisco AnyConnect Secure Mobility Client, a VPN application that establishes encrypted tunnels to Cisco VPN gateways. It includes a UI component (vpnui.exe) and a background service (vpnagent.exe) that manage connections, authentication, and traffic routing.

Cisco AnyConnect uses a modular architecture with a UI process and a background VPN agent. It creates a virtual network adapter and routes traffic through the encrypted tunnel, enabling remote access while enforcing security policies from the VPN gateway.

Quick Fact: Cisco AnyConnect introduced robust VPN tunneling with user-mode UI and a persistent agent to maintain connections across network changes.
