Is columbia.edu a scam? Here's what we found.
Excellent security hygiene with modern TLS 1.3 encryption, HSTS enforcement, and Google Web Risk identifying no threats. This indicates a strong commitment to protecting visitor data.
The WHOIS data clearly identifies Columbia University as the registrant, with the domain active since 1985, establishing a very strong and verifiable identity for this long-standing academic institution.
A high Tranco rank and clean DNS blacklist status contribute to a good reputation, though the 403 status encountered by our crawler is an unusual flag for such a prominent site.
While legally owned by a major university, the absence of obvious contact info, social media links, and even a favicon on the homepage makes the site less transparent than one would expect for a leading educational institution.
The critical absence of a privacy policy and terms of service is a major compliance concern for any website, especially one associated with an organization that handles personal and academic data.
Robust email authentication (SPF and DMARC) and quick page load times suggest a well-managed backend. The Cloudflare server is a common choice for performance and security.
