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. 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 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

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

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

The GASAG-Gruppe targets both private and business customers in Berlin and Brandenburg, offering a broad portfolio of energy products and services. Their business model emphasizes sustainability and innovation, positioning them as a regional leader in the energy transition. The company operates several subsidiaries and partner companies, enhancing their service offerings and market reach. The website content and structure support clear communication of their mission, services, and corporate governance, which is critical for maintaining trust and regulatory compliance in the energy sector.

Security posture

The website demonstrates a solid security foundation with HTTPS and consent management via Usercentrics. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a dedicated security policy, incident response page, or security.txt file suggests room for improvement in transparency and readiness for vulnerability disclosures. The use of third-party scripts is controlled, but continuous monitoring is recommended to mitigate supply chain risks. Overall, the security posture is good but could be enhanced with formalized policies and incident response information.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and frameworks.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a security.txt file to facilitate vulnerability disclosures.
  4. Ensure all recommended security headers (X-Frame-Options, X-Content-Type-Options) are present and properly configured.
  5. Regularly audit third-party scripts and update consent management to reflect all tracking technologies.

Technical notes

Notes

The website uses a modern tech stack including ES modules, Usercentrics for GDPR-compliant consent management, and Google Tag Manager for analytics. It is hosted on Microsoft Azure DNS infrastructure, indicating enterprise-grade hosting. The CMS appears to be e-Spirit FirstSpirit, a professional content management system. The site is mobile-optimized with responsive images and accessible navigation. Performance is moderate, with potential for optimization in loading times. SEO is well addressed with proper meta tags and structured data. Technical risks are minimal but should be managed through ongoing maintenance and security best practices.
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.
