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

Kévin Dunglas' website serves as a professional technical blog and portfolio highlighting his expertise as a software architect and API expert. The site prominently features his open source projects such as API Platform, FrankenPHP, Mercure.rocks, and Vulcain.rocks, positioning him as a recognized figure in the PHP and API development community. The business model revolves around open source software creation, consulting, training, and sponsorship, targeting developers and technology enthusiasts globally. The site is well-branded, consistent, and content-rich, reflecting a high level of professionalism and technical authority. Technically, the website is built on WordPress with modern plugins for SEO, social integration, and code syntax highlighting. It uses HTTPS with good SSL configuration and loads quickly with mobile optimization and accessibility considered. However, some security best practices such as explicit security headers and privacy/cookie policies are missing, which could be improved to enhance compliance and trust. From a security perspective, the site shows a mature posture with no visible vulnerabilities or exposed sensitive data. The absence of privacy and cookie policies and incident response information are notable gaps. Analytics usage is minimal and not fully configured, indicating a low level of user tracking. Overall, the site is trustworthy and safe for general audiences. Strategically, the site would benefit from adding comprehensive privacy and cookie policies, implementing security headers, and publishing vulnerability disclosure and incident response details to strengthen compliance and security posture. These improvements would enhance user trust and align the site with best practices in data protection and security governance.

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 reflects a strong market position in the technology sector, particularly in open source API and PHP development. Kévin Dunglas leverages his expertise to build and maintain influential projects that serve a global developer audience. Revenue streams likely include consulting, training, sponsorships, and possibly product support. The partnership ecosystem includes related domains for his projects and cooperative. The site’s long history and active content updates indicate sustained growth and engagement. The business model is community-driven with a focus on innovation and developer empowerment. Strategic observations suggest opportunities to formalize compliance and security policies to support scaling and enterprise adoption.

Security posture

The current security maturity level is good with HTTPS enforced and no visible vulnerabilities or sensitive data leaks. However, the lack of security headers and formal security policies limits the overall security posture. Compliance gaps include missing privacy and cookie policies and no public incident response or vulnerability disclosure mechanisms. Data protection practices appear informal, with minimal user tracking and no explicit data retention policies. Incident response readiness is unclear due to lack of published contact channels. The security culture is implied to be developer-focused but could be enhanced by formalizing policies and transparency.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Add security headers such as Content-Security-Policy, Strict-Transport-Security, X-Content-Type-Options, and X-Frame-Options to harden security.
  3. Configure or remove unused Google Analytics plugin to avoid unnecessary tracking and potential privacy issues.
  4. Publish a vulnerability disclosure policy and security.txt file to facilitate responsible reporting and incident response.
  5. Enhance transparency by providing incident response contact information and data retention policies.

Technical notes

Notes

The website uses a modern WordPress CMS with a well-curated set of plugins for SEO, social media integration, and code syntax highlighting. The tech stack includes PHP, jQuery, Prism.js, Google Fonts, and Font Awesome. Performance is optimized with DNS prefetching and asynchronous script loading. Mobile responsiveness and accessibility are well addressed. The site lacks explicit security headers which is a technical risk. Analytics integration is present but not fully configured. Hosting provider details are not disclosed. Overall, the infrastructure is stable and performant but could benefit from security hardening and privacy enhancements.
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.
