IPsec (Internet Protocol Security)

IPsec (Internet Protocol Security) is a set of protocols that secures data transmitted over the internet or other networks. It ensures privacy and authenticity by encrypting data and verifying the identity of communicating devices. Think of it as a secure private tunnel for information traveling between computers or networks, preventing hackers from reading or tampering with the data. IPsec is commonly used in Virtual Private Networks (VPNs), allowing secure remote access to organizational networks. It provides reliable security without altering the way data is routed, making online communications safer and more trustworthy.
