What this page helps you understand
The best checklist is one your team will actually use. This one focuses on public risks that can be checked quickly and discussed clearly.

Input handling
A launch-ready checklist guide connected to scan evidence
Start with transport security: HTTPS should work, HTTP should redirect safely, and forms should not submit over insecure connections.
Then review browser protections, public files, login routes, API endpoints, and user input. The goal is not perfection in one pass; it is repeatable improvement.
Use Fixnx to automate the first pass and keep the checklist connected to evidence.
Example Fixnx finding
Issue: Missing Content-Security-Policy
Risk: Medium
Evidence: The Content-Security-Policy header was not found on tested pages.
Recommended fix: Start with a report-only CSP, review violations, then enforce a policy that matches the site.
CSP can reduce browser-side injection impact when it is designed and tested carefully.
What to fix first
- Critical exposed files, admin panels, secrets, or takeover paths.
- Broken HTTPS, missing redirects, weak SSL/TLS behavior, or unsafe cookie handling.
- Confirmed injection, XSS, access-control, authentication, or sensitive API evidence.
- High-impact security headers and browser protections that reduce attack impact.
- Medium and low hardening recommendations after the risky public evidence is fixed.

FAQ
How often should I run a website security checklist?
Run it before major releases, after hosting changes, and periodically for public websites.
What should I fix first?
Fix confirmed exploitable vulnerabilities first, then likely high-impact issues, then hardening items.
What can I do after reading Website Security Checklist Guide?
Run a Fixnx scan, review the evidence, fix the highest-risk public issues first, and rescan after deployment so the report reflects the current site.
Is Fixnx only for security teams?
No. Fixnx is written for developers, agencies, founders, and security teams that need practical website risk evidence without a long setup process.
