SSL certificate is a security feature that protects the transmission of data between a website and its visitor. It makes sensitive information such as passwords or payment details encrypted and better Protected from abuse. It can be recognised by addresses starting with "https://" and lock icons. It is used on most modern websites, especially e-shops and B2B websites. Sometimes also referred to as TLS certificate.
An SSL certificate protects data transmission, but it does not, on its own, protect a website from attacks. If an attack does occur, read the article about it, What to Do If Your Website Is Compromised, and how to handle it as a company.
An SSL certificate is just one of the requirements a website must meet today. Another is a properly configured cookie banner. To find out what requirements it must meet and how much it costs to implement, see the article on cookies on the website.
