A Virtual Private Network (VPN) creates a secure tunnel between the remote user's device and the corporate network, encrypting data in transit, which helps protect sensitive corporate data from eavesdropping and man-in-the-middle attacks. Remote access and tunneling protocols can be part of a VPN solution, emphasizing the importance of encryption and a secure tunnel. A jump server, even though it acts as a bridge between different security zones, does not inherently encrypt traffic and is less suited as a comprehensive solution for remote employees' secure connectivity.
