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

Mangold Photovoltaik GmbH is a German company specializing in photovoltaic solar energy solutions, offering a comprehensive range of products and services including solar modules, inverters, mounting, maintenance, and expert consulting. With over 20 years of experience and TÜV Rheinland certification, the company holds a strong regional market position in Schwäbisch Gmünd, Germany. Their business model focuses on direct sales, installation, and customer education through training courses. Technically, the website is built on custom HTML with JavaScript libraries such as jQuery and Highslide, hosted on kasserver.com. While the site is accessible and content-rich, it lacks advanced security headers and cookie consent mechanisms, which are recommended for improved GDPR compliance and security posture. Overall, the website demonstrates good professionalism and trustworthiness but could benefit from enhanced security and privacy features.

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

10 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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';…

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 · found on this site
  • 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

Mangold Photovoltaik GmbH operates in the energy sector, targeting homeowners and businesses interested in solar power solutions. Their competitive advantage lies in their long-standing experience, certifications, and comprehensive service offerings including planning, installation, maintenance, and training. The company leverages partnerships with recognized solar product suppliers such as Q.CELLS, Fronius, and VARTA-storage, enhancing their product portfolio and market credibility. Revenue streams likely include product sales, installation services, maintenance contracts, and paid training courses. The company maintains a strong local presence with clear contact information and a showroom, supporting customer engagement and trust.

Security posture

The website currently exhibits a moderate security posture. It uses HTTPS (assumed but not confirmed from data) but lacks visible security headers such as Content-Security-Policy, HSTS, and X-Frame-Options. No incident response or vulnerability disclosure policies are found, and no security.txt file is present. Forms appear to be standard without explicit security features noted. The absence of cookie consent mechanisms is a GDPR compliance gap. No vulnerable libraries or exposed sensitive data were detected. To improve, the company should implement recommended security headers, enforce HTTPS strictly, and add privacy and security policies to enhance user trust and regulatory compliance.

Recommendations

  1. Implement a cookie consent banner to comply with GDPR requirements.
  2. Add and configure security headers including Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection.
  3. Verify and enforce HTTPS with a strong SSL/TLS configuration.
  4. Establish and publish an incident response and vulnerability disclosure policy.
  5. Enhance privacy compliance by appointing or disclosing a Data Protection Officer contact.

Technical notes

Notes

The website is built with custom HTML and uses JavaScript libraries such as jQuery, Highslide, and MediaElement.js for UI and media playback. It is hosted on servers associated with kasserver.com, a German hosting provider. The site has moderate performance and basic mobile optimization. SEO is basic with meta keywords and description present but no advanced structured data like JSON-LD or Open Graph tags detected. Accessibility features are minimal. The site does not use a CMS, which reduces complexity but may increase maintenance effort. There is an opportunity to modernize the tech stack and improve mobile responsiveness and accessibility to enhance user experience and search engine ranking.
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.
