Security Headers Fix Plan
Diagnose security headers and policies in your browser. No input is sent to a server. Use it for first-pass checks before rollout.
Status
Runs in your browser. No input is sent to a server. Use this as a first-pass diagnostic step.
How to use
Paste response headers and click “Plan”. It outputs prioritized steps.
Notes (this tool)
- The plan follows common priorities. Adjust it to your business requirements and constraints.
- Avoid all-at-once rollout; apply items incrementally and validate impact.
About this page
What does this tool do?
Prioritizes missing security headers and suggests an implementation order.
Debugging workflow (recommended)
- Check priorities with Fix Plan
- Use Security Headers Recommendation for values
- Validate with CSP/HSTS Inspect
Recommendations (practical)
- Prioritize CSP/HSTS
- Roll out gradually (report-only → enforce)
- Add lower-risk headers after core ones

Operational notes
- Recommended values are environment-dependent. Validate against functional requirements before applying.
- In production, use phased rollout with report monitoring.

FAQ
What is the safest order for remediation?
Start with low-risk/high-impact items (for example Referrer-Policy, X-Content-Type-Options), then roll out CSP/HSTS in phases with validation.
What if issues appear after rollout?
Use pre-defined rollback criteria, limit blast radius, and redeploy incrementally. Keep logs and repro steps for prevention.

Page-specific case studies
Use this page to convert findings into an executable remediation sequence with short and long-term tracks.
- Separate immediate fixes from design-heavy changes like CSP redesign.
- Reorder tasks by technical dependencies.
- Split broad-impact changes into phased rollouts.
Page-specific implementation checklist
- Attach deadlines and owners to each remediation task.
- Define done criteria with measurable header outputs.
- Define rollback triggers and rollback procedures.
- Track plan revision history for auditability.
