What is SSL (Secure Sockets Layer)?

Secure Sockets Layer (SSL) is a protocol that enables services to communicate over a network without compromising security. It creates a secure connection between the client and the server. Any amount of data is then sent securely over the connection. For example, if you process credit cards through online applications to process sensitive data such as personally identifiable information, or need to adhere to privacy standards, you should consider using SSL.
