Is ubuntu.com a scam? Here's what we found.
The site uses a modern TLS 1.3 protocol with HSTS, has a Content Security Policy, and is deemed clean by Google Web Risk, indicating a very strong security posture. The Let's Encrypt certificate is standard and fine.
With a domain age of over 21 years and a reputable registrar like MarkMonitor, the site's identity is well-established and transparent. The high Tranco rank further solidifies its legitimate presence.
The website holds an excellent global Tranco rank and is clean on all DNS blacklists, reflecting a very strong and untarnished reputation. The lack of a Trustpilot profile is not a negative for an open-source project.
The presence of clear contact information, legal pages like privacy and terms, and active social media channels demonstrates a high level of transparency and engagement with its users.
The site provides both a privacy policy and terms of service, which are essential for user trust and regulatory compliance, and a robots.txt and sitemap are well-configured for search engines.
Critical elements like email authentication (SPF/DMARC) and multiple IP resolution are well-configured, and DNSSEC is correctly unsigned as reported. However, the approaching domain expiry date is a significant concern that needs immediate attention.
