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

8 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

    • 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

  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"

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

Syna operates as a regional energy network operator in Germany, focusing on electricity and gas supply networks. Their business model centers on infrastructure management and customer service for energy consumers and partners. The website reveals a broad service ecosystem including portals for installers, partners, and customers, as well as training and seminars, indicating a well-developed partner network and customer engagement strategy. The company appears to maintain strong branding consistency and provides detailed navigation to support various stakeholder groups. The presence of related domains and partner sites like Suewag further supports a collaborative business environment.

Security posture

The website enforces HTTPS and uses Cloudflare for DNS and CDN, enhancing security and performance. Usercentrics consent management indicates GDPR compliance efforts. However, the absence of explicit security headers such as Content-Security-Policy and lack of published security policies or incident response contacts represent areas for improvement. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The security score is good but could be enhanced by adopting additional best practices and transparency measures.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service to improve transparency and compliance.
  2. Add explicit security headers (CSP, X-Frame-Options, X-Content-Type-Options) to strengthen security posture.
  3. Publish a security policy and incident response contact information to support vulnerability reporting and incident management.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance contact information visibility including verified company emails and phone numbers to improve user trust and support.

Technical notes

Notes

The website uses Adobe Experience Manager as CMS, combined with modern web components and CSS variables for theming, indicating a modern and maintainable front-end architecture. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. Performance is moderate with asynchronous loading of scripts like Google Tag Manager and Usercentrics. Mobile optimization and accessibility are good, supported by responsive design and skip links. The site uses structured navigation with multiple submenus targeting different user groups. There is room for improvement in SEO by adding more structured data beyond FAQ and enhancing metadata coverage.
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.
