IPsec VPN Definition: IPsec VPN: A secure network connection that uses the IPsec (Internet Protocol Security) protocol suite to encrypt and authenticate data transmitted between two or more endpoints over the internet.
IPsec VPN, or Internet Protocol Security Virtual Private Network, is a secure network connection that encrypts and authenticates data traffic between two endpoints using the Internet Protocol (IP). It ensures the confidentiality, integrity, and authenticity of data as it travels between devices, providing a secure tunnel for sensitive information to pass through, protecting it from unauthorized access or tampering. IPsec VPNs use various cryptographic protocols and algorithms to establish secure communication channels, making them a fundamental tool for ensuring secure remote access and secure data transmission across networks.
