If you've been directed to bris.idm.oclc.org to log in to your library's online resources, you're in the right place. This is an EZproxy authentication gateway, a standard tool used by thousands of libraries worldwide to give patrons secure access to journals, databases, and e-books. The site is a subdomain of OCLC (Online Computer Library Center), a global nonprofit that has been serving libraries for over 50 years.
The security here is up to scratch: the connection is encrypted, the certificate is valid, and there are no malware or phishing flags. The robots.txt file blocks search engine crawlers, which is normal for a login page that shouldn't appear in search results. You won't find a privacy policy or terms of service on this specific page because those documents live on your library's main website or OCLC's primary domain — that's standard practice.
There aren't many user reviews for bris.idm.oclc.org specifically, but that's true for nearly every library authentication page. The technology behind it, Shibboleth and EZproxy, is widely trusted across academic institutions. If you're wondering whether this is a scam or fake, the evidence points the other way: the operator is transparent about who they are, and the site's infrastructure is solid. Always double-check the full URL before entering your library credentials, but in this case, the domain is exactly what it claims to be.
