50Hertz Transmission GmbH · Energy · Germany
Medium risk. 5 critical or high findings in Security headers, GDPR outside view and 1 other check.
50Hertz Transmission GmbH operates as a leading transmission system operator in Germany, focusing on integrating renewable energy sources into the power grid and ensuring reliable electricity supply to approximately 18 million people in East Germany and Hamburg. The company maintains a professional and well-structured website that serves multiple stakeholders including partners, customers, investors, and the general public interested in energy transition. The business model centers on grid infrastructure development, system control, market facilitation, and customer services within the energy sector. The website content is relevant and well-organized, reflecting the company's market position and key services effectively. Technically, the website is built on ASP.NET WebForms with a modern front-end stack including jQuery, Kendo UI, and other JavaScript libraries. The site uses DNN CMS and integrates Usercentrics for cookie consent management. Performance is moderate with good mobile optimization and basic accessibility features. SEO optimization is basic but functional. The site is served over HTTPS with a good SSL configuration, though security headers are not explicitly detected. From a security perspective, the site enforces HTTPS and uses a consent management platform, indicating attention to privacy compliance. However, there is no published security policy or incident response contact, and no vulnerability disclosure or security.txt file is found. The absence of WHOIS data for the domain www.50hertz.com is a notable anomaly, potentially indicating domain registration issues or use of alternative domains. Overall, the security posture is solid but could be improved with enhanced transparency and security best practices. The overall risk assessment is moderate with a recommendation to improve domain registration transparency, publish security policies, implement security headers, and enhance accessibility and SEO. These steps will strengthen trust, compliance, and security culture, supporting the company's strategic goals in the energy sector.
Scanned
NIS2 Art. 21(2)
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.

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.

Each check with its score, findings and the evidence it collected.
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.

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.
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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
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.
