What is the STARTTLS Protocol?
STARTTLS is a protocol command used to upgrade an existing unencrypted connection to an encrypted one using Transport Layer Security (TLS). It is commonly used in email protocols such as SMTP to enable encryption during transmission.
STARTTLS provides opportunistic encryption, meaning encryption is used when supported by both parties.
What is the STARTTLS Protocol used for?
STARTTLS is used to protect email communications from interception, reducing the risk of Packet Sniffing and Man-in-the-Middle (MitM) attacks.
Organizations implement STARTTLS to enhance email security, but it is often complemented by stricter encryption policies and TLS enforcement to ensure consistent protection.
