SSL (Secure Sockets Layer) is the standard security technology for establishing an encrypted link between a web server and a browser. In simple, a SSL certiface secures your website from cyber-threats and hackings, and you avoid Google rating your website as 'not secure' to your prospects and clients.
The core function of an SSL certificate is to protect server-client communication. On installing SSL, every bit of information is encrypted. In layman’s terms, the data is locked and can only be unlocked by the intended recipient (browser or server) as no one else can have the key to open it. While dealing with sensitive data such as IDs, passwords, credit card numbers, etc., SSL helps you protect against the mischievous army of hackers and skimmers.
The primary task of an SSL certificate is to provide authentication to a website. Identity verification is one of the most important aspects as far as web security is concerned.
2. SSL helps you satisfy PCI/DSS requirements
If you accept online payments, you must know a thing or two about PCI/DSS requirements. To receive online payments, your website must be PCI compliant. Having an SSL certificate installed is one of the 12 primary requirements set by the payment card industry (PCI).
3. Better search engine ranking
Google made changes to its algorithm in order to give the upper hand to HTTPS-enabled websites. This has been evident in various studies conducted by SEO-experts around the world.
4. SSL improves customer trust
If it were up to us, we’d have renamed SSL (Secure Socket Layer) to TTL (Trust Transmitting Layer). Unfortunately, it isn’t. But that won’t stop us from singing the praises of a TTL —err, SSL certificate. Apart from encryption and authentication, SSL certificates are vital from a customer trust point of view.
