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

Sixense is an international engineering and consulting company specializing in soil knowledge, environmental monitoring, and infrastructure lifecycle management. The company offers a broad range of services including engineering, monitoring, digital solutions, and mapping, targeting infrastructure owners and operators across energy, transport, and industrial sectors. With a strong international presence and multiple offices worldwide, Sixense positions itself as a key player in infrastructure security and sustainability. Technically, the website is built on WordPress with modern frameworks like Bootstrap and integrates advanced tools such as Matomo for analytics and Complianz for GDPR compliance. However, the absence of a valid SSL certificate and HTTPS severely undermines the security posture, exposing users to risks and impacting trust. Security headers are well implemented but cannot compensate for the lack of encryption. Privacy compliance is well addressed with clear cookie and privacy policies and consent mechanisms. Overall, the site is professional and content-rich but requires urgent security improvements to align with best practices.

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. 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 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

    • 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

    • 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

Sixense operates in essential infrastructure sectors including energy, transport, and industry, providing specialized engineering and monitoring services. The business model focuses on lifecycle management of infrastructure assets through a combination of consulting, digital tools, and monitoring solutions. The company benefits from a strong brand presence, international offices, and a parent company (Soletanche Freyssinet) that enhances credibility. The website content and structure support a professional image targeting B2B clients. The presence of multiple contact points and social media channels indicates a mature marketing and communication strategy. Growth potential is supported by digital offerings and geographic diversification.

Security posture

The current security posture is weak due to the complete lack of HTTPS and SSL/TLS encryption, which is a critical vulnerability. While security headers such as HSTS, X-Frame-Options, X-XSS-Protection, and others are present, their effectiveness is limited without secure transport. No incident response or security policy information is publicly available, which may indicate gaps in transparency or maturity. The site uses modern plugins and frameworks but does not implement advanced security features like OCSP stapling or session resumption. The absence of certificate transparency compliance further reduces trust. Immediate remediation is required to secure user data and maintain compliance with regulations.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 or TLS 1.3) and disable insecure protocols.
  3. Implement HSTS with includeSubDomains and preload flags to enforce HTTPS.
  4. Add OCSP stapling and enable session resumption for improved security and performance.
  5. Publish a clear security policy and incident response contact information to enhance transparency.
  6. Regularly audit and update all plugins and frameworks to mitigate vulnerabilities.
  7. Enhance accessibility features and mobile optimization for better user experience.
  8. Maintain and update privacy and cookie policies to ensure ongoing GDPR compliance.

Technical notes

Notes

The website is built on WordPress 6.8.1 with PHP 7.4 and uses Bootstrap 5.3.3 for responsive design. It integrates several plugins including Contact Form 7, Complianz GDPR, YouTube Embed Plus, and Matomo analytics. Hosting is provided by OVHcloud. The site includes multiple international office locations with embedded Google Maps API. Performance metrics are not available, but the use of modern frameworks and CDN resources suggests moderate to good performance. SEO is supported by Yoast SEO Premium with proper meta tags and structured data in JSON-LD format. However, the lack of SSL/TLS is a major technical debt and risk. The site is mobile optimized and includes accessibility considerations but could improve in these areas. Overall, the technical stack is modern but requires urgent security upgrades.
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.
