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

Léo Chiron is a freelance full-stack web developer and webmaster based in France, with over 8 years of experience. The website serves as a professional portfolio showcasing his expertise in web development, SEO, WordPress, and site maintenance. The business targets clients needing custom website creation, e-commerce platforms, and ongoing site support. Technically, the site uses a modern tech stack including PHP, JavaScript, SQL Server, and integrates Google services such as Maps, reCAPTCHA, and Tag Manager. The hosting is provided by o2switch, a French hosting provider. Security posture is solid with HTTPS and reCAPTCHA protection on forms, but lacks explicit security headers and published privacy or cookie policies, which are compliance gaps. Overall, the domain registration data aligns well with the business claims, indicating legitimacy and trustworthiness.

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

7 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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

  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

The business operates as a small freelance entity focusing on web development and webmaster services. It leverages a portfolio of client websites and professional experience as a lead developer to position itself competitively. Revenue streams include fixed-price website projects and hourly/daily freelance maintenance and development services. The target market includes small to medium businesses and individuals seeking professional web presence and SEO optimization. The presence of a LinkedIn profile and portfolio links supports credibility. No parent or subsidiary companies are indicated. The business model is direct client engagement without intermediaries.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and Google reCAPTCHA v3 implemented to protect the contact form from spam and abuse. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces the overall security hardening. No incident response or security policy information is published, which limits transparency and preparedness perception. No vulnerabilities or exposed sensitive data were detected in the content. GDPR compliance is incomplete due to missing privacy and cookie policies. Overall, the security maturity is adequate for a small freelance site but could be improved.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement and configure security headers to enhance protection against common web attacks.
  3. Add an incident response or security contact channel to improve transparency and trust.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Consider adding accessibility improvements and explicit user consent mechanisms for tracking.

Technical notes

Notes

The website uses a modern and common technology stack suitable for freelance web development services, including PHP, JavaScript, jQuery, SQL Server, and WordPress CMS. It integrates Google APIs for maps, analytics, and spam protection. The site is mobile responsive and uses Bootstrap grid for layout. Performance is moderate with some optimization evident (e.g., lazy loading images). The use of Google Tag Manager and Google Ads indicates marketing awareness. No major technical debt or outdated libraries were detected. Hosting is via o2switch, a reputable French hosting provider. Opportunities exist to improve accessibility and security headers to reduce technical risks.
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.
