SSL and the padlock: what it does and does not mean

16 December 2025 · LMJ Web Design

Every site should have the padlock, and every site we manage does. But it is worth knowing what it actually promises.

What it means

Traffic between the visitor and the site is encrypted, so nobody on the café wifi can read the form they fill in. Browsers now mark sites without it as "not secure", and Google ranks them lower.

What it does not mean

That the site is honest, well-built or safe from being hacked. A phishing site can have a padlock. Encryption is the floor, not the ceiling.

The bit that goes wrong

Certificates expire. When one lapses, the site shows a full-page warning and visitors leave. On managed sites the certificate renews automatically and we are alerted if renewal fails, which is the kind of dull job a managed service exists to do.
