SSL/TLS (Secure Sockets Layer / Transport Layer Security) is a security protocol that protects data sent over the internet. Although many people still say “SSL,” modern websites use TLS because it offers stronger security. An SSL/TLS certificate enables encrypted communication between a website server and a user’s web browser.
When a website uses SSL/TLS, it encrypts all data during transmission. This process protects sensitive information such as passwords, personal details, and payment data. Hackers cannot easily intercept or read this encrypted data. In simple terms, it converts readable information into secure code that only the intended recipient can understand.
SSL/TLS also verifies website identity. It ensures users connect to the correct website instead of a fake or malicious copy. This verification helps prevent phishing attacks and protects user data.
You can recognise SSL/TLS by the “HTTPS” in a website’s URL and the padlock icon in the browser bar. These indicators show that the connection is secure and trustworthy.
Today, every website needs SSL/TLS. Search engines favour secure websites, which improves SEO rankings. At the same time, browsers warn users about non-secure sites. These warnings can reduce trust and increase bounce rates.
In summary, SSL/TLS protects online communication, improves website credibility, and supports better search visibility.
