    HTTPS gives your users a safe and secure connection to your website. It is recognisable by the padlock in your web browser. This is a fundamental security standard which ensures that your user’s connection cannot be tapped or manipulated.

    Why?

    • "Why HTTPS for Everything?" by CIO.gov
    • "Still think you don't need HTTPS?"by Scott Helme
