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 registrar is Gandi SAS, 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. Nameservers are provided by gandi.net, indicating managed DNS hosting. MX records point to the gandi.net email service. No CNAME was found; the observed records resolve directly to addresses. DNSSEC signatures were not detected, so this additional DNS authenticity protection is not confirmed.
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 checked browser-security headers were not detected, leaving fewer explicit browser-side safeguards. 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. The x-cache, x-served-by, via response header indicates a CDN or caching proxy in the delivery path. No obvious internal addresses or debug information were found in the headers.
Technology Stack Analysis
The public page identifies Fastly without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
No homepage meta description was detected, leaving snippet selection more dependent on page text. 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 13 characters, within a common display range.
