The website enforces HTTPS with a good SSL configuration and uses AWS infrastructure, which is generally secure. Security headers are partially present or implied but not explicitly detailed in the HTML. No sensitive data or vulnerable libraries are exposed. The site lacks a published security policy or incident response contact information, which is a gap in transparency and readiness. DNSSEC is not enabled, which is a recommended improvement for DNS security. No vulnerability disclosure program or security.txt file is found.
