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

The website dieulot.fr is a personal portfolio site for Alexandre Dieulot, a developer focused on web performance and innovative web projects such as instant.page and ip.dog. The site serves as a showcase for these projects and provides contact information for professional engagement. The domain is well established since 2011 and hosted via OVH with Cloudflare DNS, indicating a stable technical infrastructure. The website is well designed, mobile optimized, and fast loading, providing a good user experience for its target audience of web developers and tech enthusiasts. However, it lacks formal privacy, cookie, and security policies, which are important for compliance and trust. Security posture is moderate with no detected security headers or incident response information, but no critical vulnerabilities were found. Overall, the site is trustworthy and professional but could improve compliance and security transparency.

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

10 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. 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';…

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

Alexandre Dieulot operates a small-scale technology-focused personal brand and project portfolio. The business model centers on developing and promoting web performance tools and utilities, targeting web developers and technical users. The projects have niche market positions with recognized tools like instant.page that improve website speed and user experience. The site does not appear to monetize directly via advertising or affiliate programs. The presence of active social media and domain registration supports ongoing engagement and credibility. There are no indications of partnerships or subsidiaries. The business is positioned as a technical innovator in web performance.

Security posture

The website demonstrates a basic to moderate security posture. It uses HTTPS (implied by Cloudflare DNS and standard practice) but no explicit security headers were detected in the provided data. There is no privacy or cookie policy, no vulnerability disclosure or security.txt file, and no incident response contact information. No forms or user input fields reduce attack surface. The domain registration is consistent and legitimate, reducing risk of phishing or spoofing. Recommendations include adding security headers, formal privacy and cookie policies, and incident response contacts to improve compliance and security maturity.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy to improve GDPR compliance.
  2. Add standard security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  3. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Include incident response contact information such as security@ or abuse@ email addresses.
  5. Enhance accessibility features and conduct an accessibility audit to improve inclusiveness.

Technical notes

Notes

The website is built with modern HTML5, CSS3, and JavaScript technologies, using custom fonts and responsive design techniques. Hosting is provided by OVH with Cloudflare nameservers, indicating reliable infrastructure and potential CDN benefits. The site loads quickly and is mobile optimized. No CMS or frameworks were detected, suggesting a custom or static site. There is minimal use of external scripts, reducing complexity and attack surface. The site lacks advanced SEO structured data like JSON-LD but uses Open Graph meta tags for social sharing. Technical debt appears low, but adding security headers and compliance documents would improve overall technical maturity.
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.
