SSL Certificates provide secure, encrypted communications between a website and an internet browser. SSL stands for Secure Sockets Layer, the protocol which provides the encryption. SSL Certificates are typically installed on pages that require end-users to submit sensitive information over the internet like credit card details or passwords. Example pages include payment pages, online forms and login pages.
Data transferred in plain-text form or in non-encrypted format can be intercepted, eavesdropped, compromised and stolen. Transactions performed online may involve submitting personal information such as credit card information, social security numbers, usernames and passwords. Cybercriminals who intercept unencrypted communications will gain full access to this data and can use it for fraudulent purchases and activities.
