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

KALORIMETA GmbH operates a professional website focused on providing smart energy solutions and heating cost accounting services primarily for residential properties in Germany. The company positions itself as a partner for the smart energy transition in residential real estate, offering services such as heating cost accounting, smart thermostat control, and smoke detector services. The website is well-structured, content-rich, and targets landlords, residents, and corporate clients. The presence of a parent company, Noventic, is clearly indicated, enhancing business credibility. Technically, the website is built on TYPO3 CMS with modern frontend frameworks like Bootstrap and uses Cloudflare for DNS and CDN services. It integrates advanced consent management via Usercentrics and analytics through eTracker and Google Tag Manager, reflecting a mature digital infrastructure. The site is mobile-optimized, accessible, and SEO-friendly. From a security perspective, the site enforces HTTPS, employs security headers, and integrates cookie consent mechanisms. However, it lacks a dedicated security policy or incident response contact information, which could be improved. No vulnerabilities or suspicious patterns were detected in the content or WHOIS data, indicating a strong security posture. Overall, the website is professional, trustworthy, and compliant with GDPR requirements. It effectively communicates its business offerings and maintains a good balance between user experience and security. Strategic recommendations include publishing explicit security policies and incident response contacts to further enhance trust and compliance.

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

4 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

  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 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';…

  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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

KALORIMETA GmbH is positioned as a medium-sized company in the German energy and real estate sectors, specializing in heating cost accounting and smart energy solutions for residential buildings. Its business model combines B2B and B2C services, targeting landlords, property managers, and residents. The company leverages digital tools such as customer and resident portals to streamline service delivery. The parent company Noventic's involvement suggests a broader ecosystem and resource backing. The company maintains a strong online presence with active social media channels and regularly updated news content, indicating ongoing engagement and growth. The website's comprehensive service descriptions and legal compliance pages reflect a mature and transparent business operation.

Security posture

The website demonstrates a solid security posture with enforced HTTPS, modern security headers, and integration of consent management tools ensuring GDPR compliance. The use of Cloudflare DNS and CDN adds an additional layer of protection and performance optimization. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a dedicated security policy page and incident response contact limits transparency in security governance. The analytics setup respects user consent, reducing privacy risks. Overall, the site is secure for users and business operations but could benefit from enhanced security communication and formal vulnerability disclosure mechanisms.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance Content Security Policy (CSP) headers to further reduce risks of cross-site scripting and related attacks.

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, combined with Bootstrap for responsive design and jQuery for interactivity. It uses modern JavaScript libraries such as Modernizr and Plyr for enhanced user experience. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. The site loads asynchronously loaded scripts for performance optimization and integrates Usercentrics for consent management, reflecting compliance with privacy regulations.

Performance is moderate, with potential for further optimization in loading times and resource management.
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.
