Transport Layer Security (TLS)
Transport Layer Security (TLS) is an encryption standard that protects emails and sensitive information during the sending and receiving process. It also authenticates the sender and verifies email content and data to ensure the data has not been tampered with.
Other forms of cryptographic protocols include Secure Sockets Layer (SSL) and end-to-end encryption. Unlike end-to-end encryption, TLS doesn’t encrypt emails during sending. Instead, it adds a layer of security to emails, making them less prone to spoofing attacks, hacks, and other malicious activities by cybercriminals.
