Website Overview
Several search or sharing settings need attention. Together they may make snippets, preview images or preferred URLs less consistent across platforms. An active inbound-mail setup with incomplete authentication may leave the domain more open to impersonation. Provider hosting alone does not close that gap.
Domain and Registration
Transfer-protection status is present, helping reduce the risk of unauthorized domain transfers. The domain has about 5 years of registration history; its current configuration provides more context than age alone. The domain uses the common .io extension, which is not an independent safety signal.
DNS and Email
MX records exist, but SPF, DKIM and DMARC were not detected. Protection against domain impersonation may be incomplete. Nameservers are provided by Google Cloud DNS, indicating managed DNS hosting. MX records point to the Google Workspace email service. DNSSEC is enabled, allowing validating resolvers to authenticate signed DNS data. CAA records restrict which certificate authorities are authorized to issue certificates.
TLS and Certificates
The certificate uses an RSA 2048-bit public key, offering broad client compatibility. The server supplied a complete certificate chain. No organization name is present in the certificate; the available fields are consistent with domain validation. The certificate was issued by Let's Encrypt, commonly associated with automated certificate services. The certificate's total validity is about 89 days, consistent with a short renewal cycle.
HTTP and Browser Security
The response lacks these common security headers: CSP, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, clickjacking protection. CORS permits any origin to read this response. This is common for public resources; sensitive responses need narrower handling. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. No obvious internal addresses or debug information were found in the headers. The Server header contains the custom value Vercel.
Technology Stack Analysis
The public page identifies Vercel without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
The title has 78 characters and may be truncated in search results. The Generator tag identifies Docusaurus v3.7.0, making the publishing system easier to fingerprint. Open Graph is partially configured; og:type is missing. Twitter Card metadata is configured. The page declares 2 language or regional alternatives using hreflang.
