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

Hottgenroth Software AG is a German software company specializing in energy and building technology solutions. The company targets professionals and businesses within the energy sector, offering software products and customer support services. Their website is professionally designed, consistent in branding, and primarily in German, reflecting their focus on the German market. The business model centers on providing specialized software tools for energy management and building technology, positioning them as an established player in this niche industry. Technically, the website is built on ASP.NET WebForms and utilizes common web technologies such as jQuery, Bootstrap, Google Tag Manager, and Google reCAPTCHA for security. Cookie consent is managed through Consentmanager.net, indicating a basic level of privacy compliance. The site demonstrates moderate performance and good mobile optimization but lacks advanced accessibility features. SEO optimization is basic but present. From a security perspective, the site enforces HTTPS and uses reCAPTCHA to protect forms, which is positive. However, it lacks explicit security headers such as Content Security Policy and HSTS, and there is no publicly available privacy policy, terms of service, or vulnerability disclosure information. Incident response contacts and data protection officer details are also missing, which are important for compliance and trust. Overall, the website is safe and professional but could improve its privacy and security posture by publishing comprehensive policies, implementing security headers, and providing clear incident response channels. These improvements would enhance trustworthiness and compliance with GDPR and other regulations.

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

Hottgenroth Software AG operates in the energy software sector, focusing on providing specialized solutions for energy and building technology professionals. Their market positioning is that of a medium-sized, established German software provider with a clear target audience in the energy industry. The business model likely includes software licensing, customer support, and training services. The website content and structure suggest a focus on professional clients rather than consumers. There is no evidence of parent or subsidiary companies, and partnerships are not explicitly mentioned. The company maintains a professional online presence with consistent branding and moderate digital maturity.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and use of Google reCAPTCHA to protect user input forms. Cookie consent mechanisms are implemented, indicating awareness of privacy regulations. However, the absence of explicit security headers such as CSP, HSTS, and X-Frame-Options reduces the overall security posture. There is no visible privacy policy or terms of service, which are critical for GDPR compliance. Incident response readiness is unclear due to lack of contact information for security issues. No vulnerability disclosure policy or security.txt file is present. The site does not expose sensitive data or use known vulnerable libraries based on the provided content. Overall, the security posture is adequate but requires enhancements to meet higher compliance and trust standards.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service on the website.
  2. Implement and configure security headers including Content Security Policy, HSTS, X-Frame-Options, and X-XSS-Protection.
  3. Establish and publicize a vulnerability disclosure policy and incident response contact information.
  4. Enhance accessibility features to improve compliance and user experience.
  5. Regularly audit and update third-party libraries and scripts to avoid vulnerabilities.

Technical notes

Notes

The website is built on ASP.NET WebForms, a mature but older web framework, combined with modern frontend libraries such as jQuery and Bootstrap. It integrates Google Tag Manager and Google reCAPTCHA for analytics and security. Cookie consent is managed via Consentmanager.net, indicating some level of privacy compliance. The site shows moderate performance and good mobile responsiveness but lacks advanced accessibility features. SEO is basic with meta tags present but no structured data like JSON-LD detected. Hosting provider details are not explicit. The technical stack is stable but could benefit from modernization and improved security configurations.
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.
