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

Olsberg GmbH is a well-established German company specializing in the manufacture and sale of premium heating stoves, including Kaminöfen and Pelletöfen. With a history dating back to 1577, the company positions itself as an innovation leader offering timeless elegance and premium quality products. The website supports a dealer network, an online spare parts shop, and provides extensive product information and support resources. Technically, the website is built on WordPress with modern frameworks like Bootstrap and uses common plugins for analytics and cookie management. The site is mobile-optimized and provides a good user experience with clear navigation and multimedia content. Security posture is solid with HTTPS and cookie consent mechanisms, though some security headers and explicit policies are missing.

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

5 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. Network security

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

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • 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

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 company operates in the energy sector focusing on heating solutions, targeting consumers and businesses seeking high-quality stoves. Its business model includes manufacturing, retail, and after-sales support through dealer networks and online shops. The presence of subsidiaries and partner sites indicates a structured corporate ecosystem. The website content and structure reflect a mature business with a focus on product quality and customer service. The company leverages digital marketing tools and analytics for customer insights and engagement. The lack of direct contact emails or phone numbers on the main site suggests a preference for controlled communication channels, possibly via contact forms or dealer contacts.

Security posture

The website demonstrates a good security baseline with HTTPS enforced and cookie consent implemented. However, it lacks explicit security headers like Content-Security-Policy and X-Frame-Options, which are recommended to mitigate common web attacks. No security policy or incident response contacts are published, which is a gap in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of popular plugins and frameworks requires ongoing maintenance to avoid vulnerabilities. The absence of a security.txt file or vulnerability disclosure mechanism limits external security engagement. Overall, the security posture is adequate but could be improved with additional headers, policies, and incident response information.

Recommendations

  1. Implement and verify security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and provide incident response contact information to improve transparency and readiness.
  3. Regularly update WordPress core, themes, and plugins to mitigate vulnerabilities.
  4. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  5. Enhance accessibility features and conduct periodic security audits to maintain compliance and security posture.

Technical notes

Notes

The website is built on WordPress 6.8.3 using Bootstrap 4 and jQuery, with additional libraries like Owl Carousel for UI components. It integrates Google Analytics and Tag Manager for tracking and Google Maps API for location services. The Borlabs Cookie plugin manages cookie consent, supporting GDPR compliance. The site loads multiple minified CSS and JS files, indicating optimization efforts. Mobile responsiveness is good, and SEO meta tags are properly set. Performance is moderate, with potential improvements in caching and asset delivery. Accessibility is basic, with room for improvement in ARIA roles and keyboard navigation. Overall, the technical infrastructure is modern and suitable for a medium-sized business website.
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.
