Website Overview

Several search or sharing settings need attention. Together they may make snippets, preview images or preferred URLs less consistent across platforms.

Nameservers are provided by Akamai Edge DNS, indicating managed DNS hosting. MX records point to the Proofpoint 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, Atlassian, Microsoft. Such markers may also remain after a service stops being used.

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

X-Powered-By exposes backend information: Mythical Beasts. The response lacks these common security headers: X-Content-Type-Options, Referrer-Policy, Permissions-Policy. The 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. The Server header identifies Apache without an exact version.

Technology Stack Analysis

The public page identifies Drupal 10 (https://www.drupal.org), Drupal, Apache without precise versions, leaving fewer clues for version-specific scanning.

Search and Social Sharing

The meta description has 196 characters and may be shortened in search results. The Generator tag identifies Drupal 10 (https://www.drupal.org), making the publishing system easier to fingerprint. Open Graph is partially configured; og:type is missing. Twitter Card metadata is configured. The title has 27 characters, within a common display range.
