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 1994, this domain has about 32 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
Nameservers are provided by siteground.net, indicating managed DNS hosting. MX records point to the Microsoft 365 email service. SPF and DMARC are configured. DKIM status is unknown. TXT records include verification markers for Google, Microsoft. Such markers may also remain after a service stops being used. 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 response lacks these common security headers: HSTS, Referrer-Policy, Permissions-Policy. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. No obvious internal addresses or debug information were found in the headers. The Server header identifies Apache without an exact version. No explicit CDN or WAF marker was found in the response headers.
Technology Stack Analysis
The public page identifies WordPress 7.1.2, jQuery, Apache, 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 7.1.2, making the publishing system easier to fingerprint. Open Graph is partially configured; og:image is missing. Twitter Card metadata is configured. JSON-LD includes Organization data, helping describe the organization as an entity. The title has 57 characters, within a common display range.
