IPSec
IPSec is a standard security system that helps protect information as it travels across computer networks, especially the internet. Think of it like a secure tunnel that keeps data safe from unauthorized access. Network engineers and security professionals use IPSec to create safe connections between different office locations, for remote workers connecting to company networks, or to protect sensitive business communications. It's similar to other security technologies like SSL/TLS or VPNs, which all serve to keep network communications private and secure.
