Website security

Review cookie security attributes without exposing values.

The checker keeps cookie contents out of results and inspects only names and attributes that affect browser handling.

What to review

Read the finding in context.

Secure

HTTPS-only transport

Secure restricts a cookie to secure transport. SameSite=None also requires Secure in modern browsers.

HttpOnly

JavaScript access

HttpOnly can keep a server-managed session cookie out of document.cookie and reduce the impact of some XSS paths.

SameSite

Cross-site requests

Lax and Strict reduce when cookies accompany cross-site requests. The right value depends on login/payment/integration flows.

Prefixes

__Host- and __Secure-

Cookie prefixes impose additional browser rules when supported and can make intended scope easier to audit.
