Website Overview
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 1 years of registration history; its current configuration provides more context than age alone. The registrar is Porkbun LLC, a widely used domain service provider. The domain uses the common .org extension, which is not an independent safety signal.
DNS and Email
The observed email authentication setup is incomplete: DMARC is missing. The lowest TTL is 60 seconds, supporting rapid record changes at the cost of more frequent lookups. Nameservers are provided by vercel-dns.com, indicating managed DNS hosting. MX records point to the porkbun.com email service. 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 Next.js, Vercel without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
The canonical URL points to another host: https://satslayer.org/. Search engines may consolidate indexing signals there. Twitter Card metadata is configured. The title has 57 characters, within a common display range. A meta description is present, with 154 characters. The observed directives allow indexing and link following.
