What is a frame security policy?
Frame security is enforced via the CSP frame-ancestors directive (or legacy X-Frame-Options). It defines which origins can embed your pages in iframes - critical to preventing clickjacking and UI redress attacks.
What this checker validates
- Presence and syntax of
frame-ancestors - Conflicts with X‑Frame‑Options and missing coverage
- Overly broad allowances (e.g., *) and safer alternatives
How to set a safe policy
- Prefer:
frame-ancestors 'none'unless embedding is required - If partners must embed, list exact origins and review regularly
- Remove X‑Frame‑Options once CSP coverage is consistent to avoid conflicts
Tool-specific questions
Is X-Frame-Options enough?
Can I allow only a subpath?
