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

Freyssinet is a well-established global civil engineering company specializing in the construction and repair of infrastructure using advanced technologies such as post-tensioning and cable systems. With over 80 years of experience and a network of 60 subsidiaries worldwide, it serves a broad international market primarily in the energy and transportation sectors. The website reflects a mature digital presence with comprehensive content, clear navigation, and strong branding. Technically, the site is built on WordPress with modern plugins for SEO, performance, and GDPR compliance, hosted on OVHcloud. However, a critical security issue is the absence of a valid SSL certificate, resulting in no HTTPS support, which significantly impacts the security posture. Privacy and cookie policies are present and include consent mechanisms, indicating good privacy compliance. Social media integration and detailed case studies enhance business credibility. Overall, the site is professional and trustworthy but requires urgent security improvements to protect user data and maintain trust.

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

3 findings rated critical or high. Fix these first.

  1. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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 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

Freyssinet holds a strong market position as a specialist in civil engineering, leveraging its historical innovation in post-tensioning. Its business model focuses on B2B services, acting as both general contractor and subcontractor across multiple continents. The company benefits from its parent company Vinci Construction, enhancing its market reach and resources. The website's content and structure target industry professionals and clients seeking specialized infrastructure solutions. The presence of detailed case studies and employee stories supports brand trust and customer engagement. Marketing tools like Pardot and Sendinblue are used for lead generation and communication. The company’s global footprint and diversified service offerings position it well for sustained growth.

Security posture

The website demonstrates basic security best practices with several security headers implemented, including HSTS, X-XSS-Protection, and X-Content-Type-Options. However, the lack of a valid SSL certificate and absence of TLS protocols are significant vulnerabilities that expose users to potential data interception and undermine trust. No advanced security policies or incident response information is publicly available. The site uses CAPTCHA on contact forms to mitigate spam. Overall, the security posture is weak due to missing HTTPS, which should be prioritized to meet modern security standards and compliance requirements.

Recommendations

  1. Obtain and install a valid SSL/TLS certificate to enable HTTPS across the entire website.
  2. Enable TLS 1.2 or higher and configure strong cipher suites to secure data in transit.
  3. Enhance HSTS policy by including subdomains and enabling preload to prevent protocol downgrade attacks.
  4. Implement and publish a clear security policy and incident response contact information to improve transparency and readiness.
  5. Regularly audit third-party scripts and plugins for vulnerabilities and update them promptly.
Technical notes

Notes

The website is built on WordPress CMS using PHP 8.1 and integrates several plugins such as Gravity Forms for forms, Yoast SEO for search optimization, WP Rocket for performance, and GDPR Cookie Compliance for privacy management. It uses jQuery and custom JavaScript for UI interactions. Hosting is provided by OVHcloud. The site is mobile-optimized with responsive design and accessibility features. Performance metrics are not available but the use of WP Rocket and lazy loading indicates an effort to optimize load times. The absence of valid SSL and modern TLS protocols is a critical technical risk. The site’s SEO is well-managed with proper meta tags, Open Graph, and JSON-LD structured data. Overall, the technical infrastructure is modern but requires security 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.
