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

1 finding 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.

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

enercity Erneuerbare GmbH operates in the renewable energy sector with a focus on wind and photovoltaic energy parks and energy storage solutions. Their business model revolves around developing large-scale energy projects, including challenging sites like former open-cast mines, and offering tailored solutions to municipalities and landowners. The company provides investment opportunities and emphasizes partnership and sustainability. The website content and structure indicate a medium-sized enterprise with a clear market position in Germany. The company maintains a professional online presence with clear navigation and relevant content for its target audience. No direct evidence of parent or subsidiary companies was found.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and a comprehensive cookie consent mechanism aligned with GDPR requirements. No security.txt or explicit security policies are published, which is a gap in transparency and incident response readiness. The site uses third-party scripts such as Google Tag Manager and Consentmanager.net, which are common but require ongoing monitoring for vulnerabilities. No vulnerabilities or exposed sensitive data were detected in the HTML content. Security headers are implied but not explicitly visible in the HTML source. Overall, the security posture is good but could be improved by publishing formal security policies and incident response contacts.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website.
  2. Implement and expose a security.txt file to facilitate vulnerability disclosures.
  3. Explicitly configure and document security headers such as Content-Security-Policy and X-Frame-Options.
  4. Provide direct contact information for security incidents (e.g., security@enercity-erneuerbare.de).
  5. Regularly audit third-party scripts and dependencies for security vulnerabilities.

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.
