Website Overview

DNSSEC, certificate-issuance restrictions and browser-security headers provide complementary protections across several layers. 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 2015, this domain has about 11 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 Gandi SAS, a widely used domain service provider. The domain uses the common .org extension, which is not an independent safety signal.

DNS and Email

Nameservers are provided by Amazon Route 53, indicating managed DNS hosting. MX records point to the Google Workspace 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 issuer is GlobalSign nv-sa, a commercial certificate authority. 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 is valid for about 396 days in total, with 147 days remaining.

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. The x-cache, x-served-by 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 contains the custom value gunicorn.

Technology Stack Analysis

The public page identifies Fastly without precise versions, leaving fewer clues for version-specific scanning.

Search and Social Sharing

Twitter Card metadata is configured. The title has 31 characters, within a common display range. A meta description is present, with 96 characters. The observed directives allow indexing and link following. No Generator meta tag is publicly exposed.
