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

9 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"

      • OWASP A04:2025
      • ASVS V3.4.1

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

Opinion System holds a strong market position as the leading provider of controlled customer reviews for service and real estate professionals in France. The business model revolves around collecting, moderating, and publishing authentic customer feedback, supported by recognized certifications. The company targets professionals seeking to enhance their reputation and consumers seeking reliable service providers. The website's content and structure support lead generation and customer engagement, with clear calls to action and contact mechanisms. The absence of explicit privacy and cookie policies suggests room for compliance improvement. The use of Matomo and HubSpot indicates a focus on data-driven marketing and customer relationship management.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and secure form handling for user authentication. The presence of ISO certifications related to quality and market studies suggests adherence to recognized standards. However, the lack of visible security headers such as Content Security Policy, HSTS, and X-Frame-Options represents a potential area for enhancement. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Incident response and vulnerability disclosure policies are not publicly available, which could be improved to enhance transparency and readiness. Overall, the security measures are adequate but could benefit from additional hardening and policy disclosures.

Recommendations

  1. Implement and prominently display a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  2. Add standard security headers (CSP, HSTS, X-Frame-Options) to enhance protection against common web attacks.
  3. Publish an incident response and vulnerability disclosure policy to improve transparency and security posture.
  4. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.
  5. Enhance accessibility features and provide detailed SEO metadata to improve user experience and search rankings.

Technical notes

Notes

The website is built using modern JavaScript technologies, including Material Design Components for UI, Matomo for analytics, and HubSpot for form management. Hosting is provided via AWS, as indicated by the nameservers. The site is mobile-optimized with responsive design elements and good navigation clarity. Performance is moderate, with asynchronous loading of analytics scripts. The absence of a detected CMS suggests a custom or proprietary platform. Technical debt appears low, but improvements in security headers and privacy compliance are recommended to align with best practices and regulatory requirements.
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.
