SSL enforced


This security best practice should be enforced by your organization, at least for your API routes.

Here are 4 risk examples when allowing unsecure HTTP:

  • Man in the Middle attacks: hackers can intercept and alter data from a legitimate request.
  • Misuse of data: confidential information can be accessed by hackers.
  • Downranking of websites: your website can be considered insecure by search engines and rated as not trustworthy.
  • Loss of customers' trust: without a secure HTTPS padlock displayed on your website, users may rightfully consider it to be unsafe.

Using HSTS is not a solution to this problem, as it won't protect against MITM attacks and regular "public wifi sniffing" until connection has been upgraded to HTTPS. As recommended by Google, make sure that no cookies are being sent through HSTS.


Enforce using HTTPS (using an SSL certificate) in order to protect your users' connections. In most cases, this must be done at ingress/(reverse-)proxy level.

If you are using Let's Encrypt certificates, make sure to authorize HTTPS to HTTPS redirections on the path /.well-known/acme-challenge/ to avoid any issues.
