A virtual private network, or VPN, is an encrypted link between a device and a network via the Internet. The encrypted connection aids in the secure transmission of sensitive data. It protects against illegal eavesdropping on traffic and allows the user to work remotely.
Employees at a branch office, for example, could access to the main office's internal network via a VPN. A remote worker working from home, on the other hand, may need to connect to their company's internet or restricted programmes.
While you're online, a home VPN will disguise your IP address and prevent your ISP from monitoring your behaviour. When you use a VPN on your home network, you get the added benefit of anonymous browsing, which can lead to cheaper travel prices, unfettered streaming, and no digital restrictions.
A VPN can aid in the protection of that vital link. By putting your traffic through an encrypted tunnel between you and anyone attempting to spy on you, a VPN offers an extra degree of security to your online activity.
IPsec is a set of protocols (or rules) used by virtual private networks to protect a private connection between two sites, typically a laptop or smartphone and the Internet. VPNs would not be able to encrypt data and maintain user privacy without these protocols.
