When employees are outside the office, the goal is to keep all traffic between the laptop and the corporate network encrypted and authenticated. A VPN achieves this by creating an encrypted tunnel over the public internet and authenticating the user or device before granting access. Once connected, the laptop behaves as if it’s inside the company network, allowing secure access to internal resources even over potentially untrusted networks like coffee shop Wi‑Fi. This protects data in transit from eavesdropping and tampering and ensures that only authorized users reach the network.

SSL/TLS, while essential for securing individual web sessions and applications, does not by itself provide full network access to the internal corporate network; it secures specific connections rather than the entire network path. A firewall is a protective barrier at the network edge, not a remote-access mechanism. A DMZ is a network zone designed to expose services to the internet, not a solution for securely connecting roaming employees to internal resources. VPN is the right choice for secure, encrypted remote access.
