How is this different from your /magento-store-health-checklist?

Different scope, different depth, complementary.

/magento-store-health-checklist:

• Broader, covers SEO, performance, UX, content, conversion, accessibility, plus security.
• Lighter on security, ~10 security questions out of ~60 total.
• Static checklist with self-rating; no weighted scoring.
• Best for: a quarterly "is everything still okay" review.

/magento-security-score-checker (this tool):

• Narrower, security-only across 5 categories.
• Deeper, 25 questions weighted by severity, server-scored, with a prioritized fix list.
• Real numeric output, 0-100 score + A/B/C/D/F + 5 sub-scores.
• Best for: pre-PCI-audit prep, post-incident review, or a focused security improvement sprint.

Recommended cadence:

• Monthly: Run /magento-store-health-checklist as a 15-min overall posture review.
• Quarterly: Run this security score checker as a 5-min focused security drill.
• Annually: Commission a real external pentest + (if applicable) PCI assessment.

The two tools share their philosophy: free, anonymous, honest, severity-weighted, no upsell required. If the score checker surfaces a critical gap, the health checklist will usually agree, just less specifically.
