Payment page tamper detection that catches Magecart-style card skimming. Each scan loads the page in headless Chrome, SHA-256 hashes every script, inline event handler and security header (CSP, HSTS), and compares them against an approved baseline. Tag manager and analytics scripts are matched by URL and ID, and per-visit nonces are stripped, to reduce false alerts.
Alerts go to the internal team or the client based on who owns the change, approvals need a named reviewer and a second confirmation, and every decision is logged with CSV export. The admin dashboard uses passwordless one-time-code sign-in with HMAC-hashed codes and sessions, rate limits, __Host- cookies and cross-site request blocking.
Code is private (client work).
