Why It Matters
Without SSL/TLS, data travels across the internet in plain text, meaning anyone on the same network could potentially read it. This is especially dangerous on public Wi-Fi. Beyond security, SSL/TLS directly affects your business in two practical ways. First, Google uses HTTPS as a ranking signal, so unencrypted sites are at a disadvantage in search results. Second, modern browsers display prominent “Not Secure” warnings on sites without SSL/TLS, which erodes visitor trust and increases bounce rates. For any site that handles personal data, payments, or logins, encryption is not optional. It is a legal and commercial necessity.
Example
An accountancy firm’s website collects client information through an enquiry form. Without SSL/TLS, the data submitted through that form travels unencrypted and could be intercepted. After installing an SSL certificate and enabling HTTPS, all form submissions are encrypted in transit. The browser shows a padlock, the “Not Secure” warning disappears, and the firm meets its data protection obligations under GDPR. More definitions are available in the glossary.
