0–100, higher is better. How it is calculated

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 design work, including the popular Inter typeface. The target audience includes software developers and technology enthusiasts interested in open source projects and software design. The business model is primarily personal branding with some commercial activity via an online shop. Technically, the site uses modern web standards including HTML5, CSS3, JavaScript, and WebAssembly, with hosting supported by Cloudflare DNS and Google Analytics for traffic monitoring. The site is mobile optimized and performs well with good SEO practices. Security posture is solid with HTTPS enabled and domain transfer protection, but lacks DNSSEC and security headers, and does not publish privacy or cookie policies, which are compliance gaps. No contact emails or phone numbers are provided, limiting direct communication channels. Overall, the site is trustworthy and professional but could improve privacy compliance and security hardening.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

8 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The website represents a niche personal brand in the technology sector, focusing on software development and design. It leverages open source projects and technical content to build reputation and community engagement. Revenue streams likely include sales from the online shop and possibly consulting or speaking engagements. The site’s partnership ecosystem includes GitHub and Cloudflare services. Growth indicators include a large archive of projects and articles dating back over a decade. The business model is content and project-driven rather than product-centric, targeting a specialized audience of developers and designers.

Security posture

The security maturity is moderate. HTTPS is properly implemented, and domain registration includes clientTransferProhibited status to prevent unauthorized transfers. However, the absence of DNSSEC and security headers such as Content-Security-Policy and Strict-Transport-Security reduces defense-in-depth. No privacy or cookie policies are published, which is a compliance risk under GDPR. No incident response or vulnerability disclosure information is available. No forms or input fields reduce attack surface but also limit user engagement. Overall, the site is low risk but would benefit from enhanced security controls and compliance documentation.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and integrity.
  2. Implement and publish comprehensive privacy and cookie policies to meet GDPR and other privacy regulations.
  3. Add security headers including Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security to harden the site against common web attacks.
  4. Provide clear contact information or a dedicated security contact for incident reporting and vulnerability disclosures.
  5. Consider implementing a cookie consent mechanism to inform users and obtain consent for tracking.

Technical notes

Notes

The website is built with modern web technologies including HTML5, CSS3, JavaScript, and WebAssembly, indicating a high level of technical sophistication. It uses Google Analytics and Google Tag Manager for analytics and tracking. Hosting is supported by Cloudflare DNS, providing reliable DNS resolution. The site is mobile responsive and loads quickly, with well-structured meta tags for SEO. No CMS or frameworks are detected, suggesting a custom or static site architecture. The absence of security headers and privacy policies indicates areas for technical improvement. Overall, the technical infrastructure is solid but could be enhanced with additional security and compliance features.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
