Third-Party Scripts
Every third-party script loaded on your page is a potential privacy, performance, and security liability. SaaSalyst inventories all external domains your site communicates with and categorizes them by function — analytics, ads, payments, CDNs, and more.
What SaaSalyst Checks
SaaSalyst intercepts all network requests during page load in a real browser, identifies script/XHR/fetch requests to external domains, and categorizes them (analytics, ads/tracking, payment, CDN, fonts, social). Sites with 0–5 third-party domains pass, 6–15 get a warning, and 16+ fail.
Why This Matters
Third-party scripts create compliance exposure under GDPR and CCPA — each external domain that receives visitor data is a potential data processor requiring disclosure. Security teams flag heavy third-party dependency as supply chain risk.
Performance also suffers: each external domain adds DNS lookups, TLS handshakes, and blocking script execution. Enterprise procurement teams evaluate third-party dependency as part of vendor security assessments.
How to Fix It
- Audit your third-party scripts: remove any that aren't actively needed. Each script removed reduces risk and improves performance.
- Self-host critical scripts (fonts, analytics libraries) to eliminate external dependencies where possible.
- Implement Content-Security-Policy headers to control which external domains can execute scripts.
- Document all third-party data processors in your privacy policy for GDPR/CCPA compliance.
