Is eff.org a scam? Here's what we found.
The security posture is excellent, featuring a valid SSL certificate, modern TLS, clean Google Web Risk results, and no DNS blacklist presence. This indicates a well-maintained and secure website.
With a domain age of 35 years, this site demonstrates a very well-established and stable identity. The WHOIS information is publicly available, reinforcing transparency.
The extremely high Tranco rank confirms this is a widely recognized and high-traffic website, contributing significantly to its reputable status. Its long history further solidifies its standing.
The site provides clear contact information, robust branding, and a strong social media presence. However, the lack of entries in the sitemap is a minor point, potentially impacting navigability for tools, but the primary user-facing aspects are clear.
The absence of either a privacy policy or terms of service is a notable compliance gap that users should be aware of, even for a non-profit. This warrants attention particularly as a consumer safety journalist.
Email authentication (SPF, DMARC) is properly configured, indicating a professional email setup. The lack of DNSSEC is a minor weakness, but overall, the infrastructure is solid with efficient DNS resolution and a reliable server.
