How to know if your website connection is secure

We take lots of measures to help keep your files safe when they’re being sent or stored: From SSL, to HSTS, to certificate pinning, and perfect forward secrecy. And while we’re taking these steps, here are a few you can take to ensure you’re safely transmitting your important information online — like photos, usernames and passwords or bank information — on or off of Dropbox:

Step 1: Check the URL

Standard websites use the prefix “http://”, but secure websites will use “https://” – that extra ‘s’ means your connection to the website is encrypted.

Step 2: Check for a lock

Depending on your browser, when a site is secure, you’ll see a padlock displayed either in the address box or bottom right corner of your browser window.

Step 3: If you get an SSL warning, don’t click through

If your browser (i.e. Chrome or Firefox) believes that the site you’re connecting to isn’t what it should be, a warning will be displayed about the site’s security certificate being untrusted. To be safe, you shouldn’t proceed unless you know and understand the technical reason why you’ve received the warning.
