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. 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 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';…

  2. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

SympH2ony operates in the energy and transportation sectors, targeting fleet operators seeking to transition to zero-emission vehicles powered by green hydrogen. The business model includes providing vehicles, refueling stations, hydrogen supply, and related services with flexible billing based on kilometers driven. The company leverages the expertise and reputation of Messer and Toyota Tsusho Europe, enhancing market trust and positioning. The website content and linked partner domains confirm strong industry partnerships. The absence of direct contact details on the homepage suggests a controlled lead generation approach, likely via forms or partner channels. Marketing and analytics tools such as HubSpot and Facebook Pixel indicate active digital marketing efforts. No explicit certifications or security policies are published, which could be an area for future enhancement to build further trust.

Security posture

The website enforces HTTPS and implements a cookie consent banner, demonstrating compliance with basic security and privacy standards. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not visibly configured, which could expose the site to certain web-based attacks. No security.txt or vulnerability disclosure policy is present, limiting transparency for security researchers. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The use of third-party scripts from HubSpot and Facebook Pixel introduces some risk, but these are widely trusted services. Overall, the security posture is good but could be improved by adding recommended HTTP security headers and publishing security policies.

Recommendations

  1. Implement and enforce HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a security policy and vulnerability disclosure program to improve transparency and encourage responsible reporting of security issues.
  3. Enhance accessibility features to improve compliance with standards and user experience for all visitors.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerabilities are introduced via external resources.
  5. Consider publishing incident response contact information and data protection officer details to strengthen trust and compliance posture.

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.
