Website Overview
An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality. Several search or sharing settings need attention. Together they may make snippets, preview images or preferred URLs less consistent across platforms.
Domain and Registration
Registered in 1998, this domain has about 28 years of history. That suggests continuity, although ownership and purpose may have changed. Transfer-protection status is present, helping reduce the risk of unauthorized domain transfers. The domain uses the common .org extension, which is not an independent safety signal.
DNS and Email
Nameservers are provided by NS1, indicating managed DNS hosting. MX records point to the Google Workspace email service. No CNAME was found; the observed records resolve directly to addresses. SPF and DMARC are configured. DKIM status is unknown. TXT records include verification markers for Google. Such markers may also remain after a service stops being used.
TLS and Certificates
The certificate includes the organization field Rutgers, The State University of New Jersey. The certificate uses an RSA 2048-bit public key, offering broad client compatibility. The server supplied a complete certificate chain. The certificate is valid for about 198 days in total, with 121 days remaining. The certificate SAN covers 7 names.
HTTP and Browser Security
X-Powered-By exposes backend information: Express. The response lacks these common security headers: CSP, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, clickjacking protection. No obvious internal addresses or debug information were found in the headers. Cookie security attributes are unknown. No explicit CDN or WAF marker was found in the response headers.
Technology Stack Analysis
The public page identifies Bootstrap, Express without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
The meta description has 397 characters and may be shortened in search results. No homepage canonical URL was detected. If duplicate URLs exist, consolidation may be less explicit. Open Graph is partially configured; og:type is missing. Twitter Card metadata is configured. The title has 18 characters, within a common display range.
