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 2010, this domain has about 15 years of history. That suggests continuity, although ownership and purpose may have changed. The registrar, CSC Corporate Domains, Inc., specializes in corporate domain and brand management, suggesting attention to domain asset protection. Transfer-protection status is present, helping reduce the risk of unauthorized domain transfers. The domain uses the common .io 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 Cloudflare Email Routing email service. DNSSEC is enabled, allowing validating resolvers to authenticate signed DNS data. CAA records restrict which certificate authorities are authorized to issue certificates. No CNAME was found; the observed records resolve directly to addresses.
TLS and Certificates
The certificate includes the organization field VMware LLC. The certificate issuer is DigiCert Inc, a commercial certificate authority. The certificate uses an RSA 2048-bit public key, offering broad client compatibility. The server supplied a complete certificate chain. The certificate is valid for about 396 days in total, with 207 days remaining.
HTTP and Browser Security
The response lacks these common security headers: CSP, Permissions-Policy. CORS permits any origin to read this response. This is common for public resources; sensitive responses need narrower handling. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. 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.
Technology Stack Analysis
The public page identifies Gatsby 5.13.7, Google Tag Manager, Cloudflare, 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 Gatsby 5.13.7, making the publishing system easier to fingerprint. Open Graph is partially configured; og:title, og:description, og:type is missing. Twitter Card metadata is configured. The title has 13 characters, within a common display range. A meta description is present, with 63 characters.
