Website Overview

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 2017, 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 registrar is GoDaddy.com, LLC, a widely used domain service provider. Registration contact information is publicly available through RDAP. The domain uses the common .ai 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. 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

X-Powered-By exposes backend information: Next.js. The response lacks these common security headers: Referrer-Policy, Permissions-Policy. The cf-ray 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 cloudflare without an exact version.

Technology Stack Analysis

The public page identifies WordPress, Next.js, Google Tag Manager, Cloudflare, Vercel without precise versions, leaving fewer clues for version-specific scanning.

Search and Social Sharing

The meta description has 192 characters and may be shortened in search results. Twitter Card metadata is configured. JSON-LD includes Organization data, helping describe the organization as an entity. The title has 51 characters, within a common display range. The observed directives allow indexing and link following.
