Practical Security Guides For Your Team

Your server's encryption setup has a misconfiguration in how it handles a specific downgrade-prevention signal. When a browser tries to detect whether someone is tampering with its connection, your server responds with the wrong error — like a smoke detector that beeps when you test it, but with the wrong tone. The protection may still be partially in place, but the server isn't behaving according to the standard, which can confuse security tools and warrants a closer look.

Your website already uses a secure connection (HTTPS), which is great. But there's a setting that tells browsers how long to remember to always use that secure connection — and yours is set too low. Think of it like a reminder that expires too quickly: if a user's browser forgets before their next visit, there's a brief window where they could be exposed to a connection that isn't fully protected.

Your web server is missing a simple one-line instruction that tells browsers how to handle the files it sends. Without it, some browsers may try to 'guess' what type of file they've received — and in certain situations, that guess could cause a harmless-looking file to be treated as executable code. Think of it like a label on a package: without it, the delivery driver has to guess what's inside.

Your website is missing a small but important instruction it should send to browsers — one that tells them to always use a secure, encrypted connection. Without it, browsers may occasionally connect over an unencrypted channel, and there is no browser-level safeguard to prevent that from happening. Think of it like a lock on your front door: your HTTPS certificate is the lock, but this header is the sign that tells visitors to always use the locked entrance.
