Security headers: B, 70 out of 100

Number 40 of 95 in the ranking. Missing 3 of the 9 headers we check.

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

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

Missing 3

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.
Cross-Origin-Opener-Policy 0 of 5

Cuts the link between the product's window and windows opened by, or opening, other sites.

Without it: A page that opens the product keeps a handle on its window and can later redirect it to a look-alike sign-in or payment page (tab-nabbing) while the user thinks they are still on the real site. It is also part of the isolation browsers need to defend against Spectre-style attacks.
Cross-Origin-Resource-Policy 0 of 5

Tells browsers which sites may load this site's resources.

Without it: Other sites can pull the product's responses into their own pages, which makes side-channel leaks of what a signed-in user can see easier.
