A Virtual Private Network, or VPN, is used primarily for the purposes of remote access and protecting confidential data. In particular cases, it can be imperative for a small business to use a VPN to cut costs and save time.
In simple terms, a VPN establishes a point to point connection between two points and allows a user to access another computer from their own, usually using tunnelling protocols.
In order to protect your data and to stop other users from intercepting the data during transmission, the traffic is often encrypted with cryptographic network protocols like SSH or IPsec.
In the past, encryption ciphers were simpler, but as computers have advanced to generate complex ciphers, it is difficult for humans to manually decode them.
Levels of complexity in the encryption vary depending to what level a user wishes to protect their data, but usually a simple SSH tunnel allows remote and protected access from one device to another.
Businesses often use a VPN as an auxiliary tool to support certain aspects of the company:
