Website Overview

Identifiable technologies and additional version or configuration signals make the service easier to fingerprint, which may help targeted scanners narrow their checks. An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality.

Domain and Registration

Registered in 2018, this domain has about 8 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 domain uses the common .com 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 ovh.net, indicating managed DNS hosting. MX records point to the ovh.net email service. DNSSEC is enabled, allowing validating resolvers to authenticate signed DNS data. No CNAME was found; the observed records resolve directly to addresses.

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 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

X-Powered-By exposes backend information: PHP/8.2. The response lacks these common security headers: HSTS, CSP, X-Content-Type-Options, Permissions-Policy, clickjacking protection. CORS permits any origin to read this response. This is common for public resources; sensitive responses need narrower handling. No obvious internal addresses or debug information were found in the headers. Cookie security attributes are unknown.

Technology Stack Analysis

The public page identifies WordPress 5.8.19, Google Analytics, PHP, with exact versions exposed for 1 technologies. These details can narrow vulnerability checks, although exposure alone is not a vulnerability.

Search and Social Sharing

The Generator tag identifies WordPress 5.8.19, making the publishing system easier to fingerprint. Twitter Card metadata is configured. JSON-LD includes Organization data, helping describe the organization as an entity. The title has 46 characters, within a common display range. A meta description is present, with 147 characters.
