Website Overview
An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality. 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
Registered in 2015, this domain has about 10 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 registrar is Gandi SAS, a widely used domain service provider. 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 Cloudflare, 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 public key uses EC with 256 bits. 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 within the Google Trust Services cloud or CDN ecosystem. The certificate's total validity is about 90 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 cf-ray 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 Tailwind CSS, Cloudflare without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
The title has 67 characters and may be truncated in search results. Twitter Card metadata is configured. A meta description is present, with 141 characters. The observed directives allow indexing and link following. No Generator meta tag is publicly exposed.
