0–100, higher is better. How it is calculated

PowerNet is a well-established sector-crossing conference focused on the energy transition in Northern Germany, organized by the Gesellschaft für Energie und Klimaschutz Schleswig-Holstein (EKSH). The website presents a professional and comprehensive platform for event information, networking, and expert exchange, targeting stakeholders from business, science, municipalities, and government. The site is built on TYPO3 CMS with modern frontend technologies, offering good performance, mobile optimization, and accessibility. Security posture is solid with HTTPS and cookie consent mechanisms, though some security headers and incident response information are missing. The WHOIS data is incomplete and malformed, which slightly reduces domain trustworthiness, but the strong presence of official partners and government affiliations supports legitimacy. Overall, the website is a credible and professional resource for the energy transition community in Schleswig-Holstein.

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

7 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 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. 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

The business operates as a non-profit entity focused on promoting and facilitating the energy transition through conferences and networking events. It holds a leading position regionally in Schleswig-Holstein and Northern Germany, supported by government ministries and industry partners. The business model centers on event organization and knowledge exchange rather than direct commercial sales. The target audience includes energy professionals, policymakers, and researchers. The partnership ecosystem is robust, involving multiple official and industry organizations, enhancing credibility and reach. Growth indicators include recurring events and expanding partner networks. The company is relatively small but influential within its niche sector.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, cookie consent, and no visible exposure of sensitive data. However, the absence of key security headers such as Content-Security-Policy and lack of published incident response or vulnerability disclosure policies indicate room for improvement. No known vulnerabilities or malware were detected. GDPR compliance is evident through privacy and cookie policies. The incomplete WHOIS data is a minor concern but does not directly impact website security. Overall, the site is secure for its purpose but would benefit from enhanced security best practices and transparency.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to strengthen defense against common web attacks.
  2. Publish a security policy and incident response contact information to improve transparency and readiness for security incidents.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure and improve trust with security researchers.
  4. Enhance WHOIS data transparency by ensuring accurate and complete domain registration information is publicly available.
  5. Continue maintaining GDPR compliance and regularly review cookie consent mechanisms to align with evolving privacy regulations.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, combined with modern JavaScript libraries such as jQuery, Foundation framework, and Slick slider for UI components. Hosting appears to be provided by jweiland-hosting.de, a reputable German hosting provider. The site demonstrates good mobile responsiveness and accessibility features. Performance is moderate, with optimized images and asynchronous script loading. SEO is well addressed with proper meta tags and Open Graph data. There is no indication of technical debt or outdated technologies, suggesting a well-maintained infrastructure. Opportunities exist to improve security headers and add structured data for enhanced search engine understanding.
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.
