Security Headers and HTTPS

Set headers that block common attacks.

Headers as a First Defense

A few response headers tell the browser how to behave safely. They are cheap to add and block whole classes of attacks.

Why HTTPS Is Non-Negotiable

Over plain HTTP, anyone on the path can read or change traffic. HTTPS encrypts it so passwords and tokens stay private.
