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

Bruno Simon's website is a personal portfolio showcasing his work as a creative developer based in Paris. The site highlights his freelance services and educational offerings related to web development, particularly using three.js technology. The business model centers on personal branding and teaching, targeting developers and learners interested in creative coding. The domain is well-established since 2009, indicating a stable online presence. Technically, the website employs modern web technologies including three.js for interactive 3D content, Google Fonts for typography, and Google Analytics and Tag Manager for user tracking. The site is hosted by IONOS SE and uses HTTPS, ensuring basic transport security. Performance and mobile optimization appear good, though accessibility features are basic. SEO is supported by proper meta tags and Open Graph data. From a security perspective, the site lacks advanced security headers and DNSSEC is not enabled, which could be improved. No privacy or cookie policies are present, and no consent mechanisms for tracking are implemented, indicating gaps in privacy compliance. No contact or incident response information is provided, limiting transparency and user trust. The WHOIS data is consistent and legitimate, with no suspicious patterns. Overall, the website is professional and functional with good technical implementation but requires enhancements in privacy compliance, security best practices, and contact transparency to improve trust and regulatory adherence.

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 an individual freelance developer and educator with a niche focus on creative web development using three.js. The market positioning is that of a specialized personal brand offering both freelance services and educational content. Revenue streams likely include freelance projects and paid courses or tutorials. The target audience includes web developers, creative coders, and learners seeking to improve their skills. The partnership with threejs-journey.com suggests an ecosystem around educational content. Growth indicators include a long domain history and active use of modern web technologies. The business operates independently without subsidiaries or parent companies.

Security posture

The security maturity level is moderate. HTTPS is enabled, and domain transfer is protected by clientTransferProhibited status. However, the absence of DNSSEC and security headers such as Content-Security-Policy and Strict-Transport-Security reduces the overall security posture. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is weak due to missing privacy and cookie policies and lack of consent mechanisms. Incident response readiness is not evident as no security contact information is provided. The use of Google Analytics without visible consent may pose compliance risks under GDPR. Overall, the security culture appears informal, typical for a personal portfolio site.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish comprehensive privacy and cookie policies with GDPR compliance details.
  4. Add visible contact information including a security or abuse contact email.
  5. Consider adding a vulnerability disclosure policy and security.txt file to improve transparency and trust.

Technical notes

Notes

The website uses a modern technology stack centered on three.js for 3D interactive content, supported by Google Fonts and Google Analytics for typography and analytics respectively. The hosting provider is IONOS SE, a reputable registrar and hosting company. The site loads quickly and is mobile optimized with responsive design. SEO is supported by well-structured meta tags and Open Graph data. No CMS or frameworks beyond three.js are detected. There is no evidence of technical debt or outdated libraries. Accessibility is basic but could be improved with ARIA attributes and semantic HTML enhancements. Overall, the technical infrastructure is solid for a personal portfolio site.
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.
