IPsec

IPsec (Internet Protocol Security) is a set of protocols that creates a secure, encrypted connection between two computers over the internet. Think of it like a private, invisible tunnel that keeps your data safe from eavesdroppers and hackers while it travels between locations. It's commonly used by businesses and organizations to securely connect remote offices or employees to the main network. By authenticating devices and encrypting data, IPsec ensures sensitive information remains confidential and protected during transmission, maintaining trust and security over potentially insecure networks.
