Is duckduckgo.com a scam? Here's what we found.
Security is strong overall, with a valid SSL certificate using TLS 1.3, HSTS, CSP, and clickjacking protection, but a high number of external scripts presents a minor potential risk.
The domain has been active for over 18 years, indicating a well-established entity, though the upcoming domain expiry should be watched.
With a high Tranco rank, clean Google Web Risk, and no DNS blacklist detections, the site maintains a solid reputation as a major internet player.
Contact information and legal pages are present, contributing to good transparency. However, the absence of social media links on the homepage is a slight omission for a prominent business.
The presence of both privacy policy and terms of service pages demonstrates good adherence to standard legal and user compliance expectations.
The infrastructure is robust, featuring strong email authentication (SPF, DMARC), a sitemap, present robots.txt, and fast page load times, supporting reliability and discoverability.
