Security headers: C, 65 out of 100
Number 47 of 105 in the ranking. Missing 3 of the 9 headers we check.
Below the B minimum (70/100) in our RFP clause. A buyer using it would ask for a dated fix for each missing header.
With these headers missing, docker.com is more exposed to malicious JavaScript, redirected forms, hijacked payments and clickjacking.

Content-Security-Policy 0 of 25
Tells the browser which scripts may run on the page, where its forms may submit, and where it may send data.
Without it: This is the main defence against malicious JavaScript. If an attacker gets any script onto the page (through a bug, a compromised analytics tag, chat widget or ad, or a poisoned package), the browser runs it with the signed-in user's full access. It can capture what they type, quietly point a sign-in or checkout form at the attacker's server, and skim card numbers as they are entered. A strict policy blocks scripts it does not list, and its form-action and connect-src rules leave stolen data nowhere to go.
-
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.
