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 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. 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
The lowest TTL is 60 seconds, supporting rapid record changes at the cost of more frequent lookups. Nameservers are provided by Amazon Route 53, indicating managed DNS hosting. MX records point to the Microsoft 365 email service. 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, Payload. The response lacks these common security headers: X-Content-Type-Options, Referrer-Policy, Permissions-Policy. No obvious internal addresses or debug information were found in the headers. The Server header contains the custom value Vercel. No explicit CDN or WAF marker was found in the response headers.
Technology Stack Analysis
The public page identifies Next.js, Google Tag Manager, Vercel without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
No homepage canonical URL was detected. If duplicate URLs exist, consolidation may be less explicit. Open Graph is partially configured; og:type is missing. Twitter Card metadata is configured. The title has 17 characters, within a common display range. A meta description is present, with 105 characters.
