Security Policy & Cryptographic Data Integrity Standards

Markets In Spain operates on an immutable, edge-rendered Jamstack architecture backed by Cloudflare Pages, enforcing TLS 1.3 encryption, Content Security Policies, and zero database-stored user credentials.

Edge Infrastructure & Transport Layer Security (TLS)

All HTTP requests to marketsspain.online and its edge endpoints are terminated via modern TLS 1.3 cryptographic protocols with automated HTTP Strict Transport Security (HSTS) preloading. Cleartext HTTP traffic is permanently redirected to secure HTTPS via 301 edge redirects.

Our static assets and HTML documents are pre-compiled and served directly from edge nodes with sub-millisecond cryptographic integrity verification, eliminating server-side SQL injection or remote code execution vulnerabilities.

Content Security Policy (CSP) & Subresource Integrity

To prevent cross-site scripting (XSS), data exfiltration, or malicious script injection, we maintain strict HTTP security headers:

  • Content-Security-Policy: Restricting script execution strictly to verified first-party scripts and approved Google Fonts endpoints.
  • X-Content-Type-Options: nosniff: Enforcing strict MIME-type sniffing prevention.
  • X-Frame-Options: DENY: Preventing clickjacking and unauthorized iframe embeddings.
  • Referrer-Policy: strict-origin-when-cross-origin: Protecting user referral context across external navigation.
