Website Overview

An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality. Several search or sharing settings need attention. Together they may make snippets, preview images or preferred URLs less consistent across platforms.

Domain and Registration

Registered in 2014, this domain has about 12 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 .org extension, which is not an independent safety signal.

DNS and Email

Nameservers are provided by DigitalOcean, indicating managed DNS hosting. MX records point to the Zoho Mail email service. CAA records restrict which certificate authorities are authorized to issue certificates. No CNAME was found; the observed records resolve directly to addresses. SPF and DMARC are configured. DKIM status is unknown.

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

No X-Powered-By header was found, reducing one common source of backend fingerprinting information. All six checked browser-security headers are present. Their effectiveness still depends on the policy values and application behavior. 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 Apache without precise versions, leaving fewer clues for version-specific scanning.

Search and Social Sharing

The title has 86 characters and may be truncated in search results. The meta description has 185 characters and may be shortened in search results. Open Graph is partially configured; og:description is missing. Twitter Card metadata is configured. The observed directives allow indexing and link following.
