For many users, a VPN is simply an “On” button. However, when it comes to building your own secure tunnel, it’s important to understand its architecture. OpenVPN is based on two key ideas: the client-server model and Public Key Infrastructure (PKI).

The Client-Server Model

The concept is simple:

Server — the entry point into your secure network. It constantly “listens” for incoming requests and is ready to accept connections.
Client — your device (laptop, phone) that initiates the connection to the server.

Once the server and client “agree,” a secure tunnel is created between them, and all traffic passes through it.

We needed to find out why the site periodically goes down. Mikhail conducted an audit and found the problem. He's a competent specialist — a pleasure to work with. He approaches tasks responsibly, doesn't disappear or forget )))
