Yapıdan

Meets the B minimum (70/100) in our RFP clause.

With these headers missing, yapidan.com is more exposed to man-in-the-middle attacks, redirected forms and hijacked payments.

Missing 1

• Strict-Transport-Security 0 of 20

  Tells browsers to use HTTPS for this domain, every time, without trying plain HTTP first.

  Without it: The site is open to man-in-the-middle attacks. The first request a user makes (typing the domain, following an old http:// link) can go out unencrypted, and anyone on the same network, such as café, hotel or airport Wi-Fi, can intercept it before the redirect to HTTPS. From there they can read passwords, session cookies and card numbers, serve a fake sign-in page, or inject their own JavaScript into the real one.
