HTTPS

HTTPS (HyperText Transfer Protocol Secure) is the encrypted version of HTTP, the foundational protocol used to transfer data between a web browser and a server. HTTPS wraps the standard HTTP communication inside a TLS (Transport Layer Security) layer, which encrypts every byte of data exchanged between the two endpoints. This means that login credentials, form submissions, payment details, and any other information sent through the connection cannot be read or modified by anyone intercepting the traffic — whether that is someone on the same Wi-Fi network, an internet service provider, or a malicious actor. You can identify HTTPS connections by the padlock icon in your browser's address bar and the "https://" prefix in the URL.

Browsers now flag non-HTTPS sites with a visible "Not Secure" warning, which erodes reader trust immediately. Beyond trust, HTTPS is a confirmed Google ranking factor, giving secure sites a measurable advantage in search results. For any publication that collects lead data through forms or processes payments, HTTPS is not optional — it is a baseline requirement for privacy regulations like GDPR and PCI DSS. Even for content that does not collect data, the absence of HTTPS signals to visitors that the publisher has not invested in basic security, which reflects on overall brand credibility.

Every flipbook and document published through FlipLink is served over HTTPS by default, with no additional configuration needed. FlipLink's viewer at go.fliplink.me uses TLS encryption for all traffic, protecting reader interactions including [lead capture](/features/lead-capture) form submissions and payment transactions. When you set up a [custom domain](/features/custom-domains) for your publications, FlipLink automatically provisions and manages an SSL certificate for that domain through Let's Encrypt, so your branded links remain fully secure without manual certificate management. Certificate renewals happen automatically — you never need to worry about expiration. All [embedded](/glossary/embed-code) flipbooks also inherit HTTPS when the host page uses it, maintaining a secure chain throughout.
