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

Arc'Antique is a French government-affiliated heritage preservation laboratory with over 30 years of expertise in conservation-restoration, material analysis, scientific imaging, research, and training. The website reflects a mature digital presence with professional design, clear navigation, and comprehensive content targeting heritage professionals, researchers, and the public. Technically, the site uses Jalios JCMS CMS, Google Tag Manager for analytics, and a cookie consent manager, indicating a modern and privacy-conscious infrastructure. Security posture is good with HTTPS and consent mechanisms, though lacking some advanced security headers and published security policies. WHOIS data is unavailable, which slightly reduces domain trust but is mitigated by strong government affiliation and professional content. Overall, the site is trustworthy, well-maintained, and compliant with GDPR requirements.

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

6 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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 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';…

  3. GDPR outside view

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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 organization operates in the government and heritage preservation sectors, providing essential services in conservation and research. Its market position is strong regionally, supported by the Département de Loire-Atlantique. The business model is public sector funded, focusing on cultural heritage preservation and education. The website links to multiple partner heritage sites and museums, indicating a collaborative ecosystem. The presence of a LinkedIn profile and professional content suggests active engagement with stakeholders and the public. Growth indicators include ongoing research projects and training offerings.

Security posture

The website demonstrates a solid security foundation with HTTPS and cookie consent mechanisms. However, it lacks explicit security headers such as Content-Security-Policy and does not publish a security policy or incident response contact, which are best practices for transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of WHOIS data is a minor concern but does not significantly impact the overall security posture given the site's government affiliation and professional presentation.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information on the website.
  2. Add security headers including Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security to enhance protection.
  3. Publish a vulnerability disclosure policy or security.txt file to improve transparency and trust.
  4. Investigate and resolve the lack of WHOIS data or consider domain registrar updates to improve domain trustworthiness.
  5. Continue maintaining GDPR compliance and enhance user privacy controls where possible.

Notes

The website is built on Jalios JCMS, a specialized CMS for content management, with integration of Google Tag Manager for analytics and Orejime for cookie consent management. The site is responsive and optimized for mobile devices with good accessibility features. Performance is moderate, with potential for improvement in loading speed. The technical implementation is modern and aligns with best practices for government and heritage sector websites. Opportunities exist to enhance security headers and improve domain registration transparency.
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.
