AI Summary
The website rsms.me is a personal portfolio and project showcase site for Rasmus Andersson, a Swedish software developer based in San Francisco. The site highlights a variety of software projects, technical talks, and personal interests, targeting software developers and technology enthusiasts. The business model is primarily personal branding with some e-commerce elements such as a shop for posters and typefaces. The site is well-structured with good content quality and consistent branding, serving a niche audience in the technology sector. Technically, the website uses modern web standards including HTML5, CSS3, JavaScript, and WebAssembly. It leverages Cloudflare for DNS and likely CDN services, and integrates Google Analytics and Google Tag Manager for user tracking. The site is mobile optimized and performs well, though accessibility features are basic. SEO optimization is present but minimal. From a security perspective, the site enforces HTTPS and has domain transfer protections in place. However, DNSSEC is not enabled, and no security headers were detected in the provided data. There is no published privacy policy, cookie policy, or terms of service, which impacts compliance and user trust. No contact information or incident response channels are provided, limiting transparency. The site does not appear to be behind a WAF or security challenge, and no vulnerabilities were identified in the analysis. Overall, the website is safe, professional, and technically sound but lacks formal privacy and security documentation. Strategic improvements in privacy compliance, security headers, and contact transparency would enhance trust and compliance posture.

Security Posture Analysis
Comprehensive Security Assessment
The security maturity of rsms.me is moderate. HTTPS is enforced, and domain transfer protections are active, which are positive indicators. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options represents a gap in defense-in-depth. The lack of privacy and cookie policies, as well as missing incident response contacts, indicates limited compliance with GDPR and best practices. No vulnerability disclosure or security.txt files were found, reducing transparency for security researchers. The use of Google Analytics introduces moderate user tracking, but no cookie consent mechanism was detected. Overall, the site is secure enough for its purpose but would benefit from enhanced security controls and compliance documentation.
