Website Overview

An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality. Page metadata, canonical configuration and social previews work together to provide more consistent search and sharing presentation.

Domain and Registration

Registered in 2016, this domain has about 10 years of history. That suggests continuity, although ownership and purpose may have changed. The domain uses the common .to extension, which is not an independent safety signal.

DNS and Email

Nameservers are provided by Cloudflare, 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, Apple, Meta. Such markers may also remain after a service stops being used.

TLS and Certificates

The certificate issuer is GlobalSign nv-sa, a commercial certificate authority. 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 is valid for about 396 days in total, with 104 days remaining.

HTTP and Browser Security

The response lacks these common security headers: Permissions-Policy. 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 React, Varnish without precise versions, leaving fewer clues for version-specific scanning.

Search and Social Sharing

Twitter Card metadata is configured. The title has 13 characters, within a common display range. A meta description is present, with 83 characters. The observed directives allow indexing and link following. No Generator meta tag is publicly exposed.
