E-commerce website security benchmarks — how online stores score
E-commerce sites carry an unusual amount of front-end complexity — payment widgets, analytics SDKs, A/B test scripts, chat tools, and recommendation engines all execute in the customer's browser, often before checkout. That breadth makes a tight Content-Security-Policy unusually hard to ship without breaking pricing or cart state, which is why CSP is the most-skipped header across the sector. TLS posture is generally strong (PCI DSS sets a high floor) but the browser-side controls have meaningful room to grow.

62–82/ 100
Approximate range based on common findings in this sector. For live data, scan any of the representative sites listed below.
What they tend to get right
TLS protocols and certificates are almost always modern (TLS 1.2+, valid chains, automated renewal). PCI DSS scoping forces baseline cryptographic hygiene that most non-regulated industries don't enforce. Cookie attributes (Secure, HttpOnly, SameSite) on session and cart cookies are typically correct because cart-recovery flows would break otherwise.
Where they fall short
CSP is the headline gap — large stores often skip it entirely or ship CSPs so permissive that they offer no real protection (script-src includes wildcards, unsafe-inline, and unsafe-eval to keep tag managers happy). Permissions-Policy is rare. Server banners frequently leak the platform (Shopify-Storefront-Renderer, Magento, etc.), narrowing exploit research for attackers.
Common findings in this sector
Findings that show up frequently across e-commerce sites we’ve scanned, ranked by approximate prevalence.
- ~78% of sites
Often skipped to avoid breaking tag managers and ad scripts
- ~60% of sites
When present, allowlists frequently include 'unsafe-inline'
- ~72% of sites
Rarely set even though most stores don't need camera/mic/geolocation
- ~45% of sites
Platform banners (Shopify, Magento) make targeting easier
- ~35% of sites
Order-confirmation mail goes out under brand, but DMARC stays at p=none

Regulatory context
Stores handling card data are in PCI DSS scope. PCI 4.0 specifically calls out script management on payment pages (Requirement 6.4.3) — CSP is the canonical way to satisfy that.
