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

Josko windows and doors GmbH is an innovative manufacturer specializing in windows, front doors, and interior doors, targeting both B2B and B2C customers. The company positions itself as a unique and visionary player in the manufacturing sector, primarily serving the Austrian market. The website reflects a medium-sized enterprise with a professional online presence, leveraging TYPO3 CMS and modern web technologies to deliver a good user experience with mobile optimization and clear navigation. The business model focuses on manufacturing and direct sales of high-quality door and window products. Technically, the site employs standard security practices including HTTPS, security headers, and cookie consent mechanisms, alongside extensive use of third-party analytics and advertising platforms such as Google Analytics, Facebook Pixel, and Taboola. Privacy compliance is well addressed with a comprehensive privacy and cookie policy, including GDPR compliance indicators. However, the site lacks explicit terms of service and security policy pages, which could enhance trust and compliance. Overall, the security posture is strong with no critical vulnerabilities detected, and the WHOIS data confirms the legitimacy and consistency of the domain registration with the business claims. Strategic recommendations include adding terms of service, publishing security policies, and improving accessibility features to further strengthen the website's compliance and user trust.

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

3 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 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. 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
    • 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

Josko operates in the manufacturing sector with a focus on windows and doors, serving a European market with a medium-sized business footprint. The company leverages digital marketing and analytics extensively, indicating a mature approach to customer engagement and advertising. The use of multiple ad networks and tracking pixels suggests a strategy aimed at targeted advertising and retargeting to maximize market reach. The absence of explicit contact information on the site may indicate a preference for partner or dealer-based sales channels. The company’s branding is consistent and professional, supported by social media verification and domain ownership transparency. Growth potential is supported by the innovative positioning and comprehensive digital presence, although further transparency in terms of service and security policies could improve customer confidence and regulatory compliance.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and multiple security headers implemented, including HSTS and X-Content-Type-Options. The use of Cookiebot for cookie consent with blocking mode indicates a proactive approach to privacy compliance. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the lack of a published security policy and incident response contact information represents a compliance gap. The extensive use of third-party tracking and advertising services increases the attack surface but is managed through consent mechanisms. Overall, the security maturity is good, with recommendations to formalize security policies and incident response procedures to enhance readiness and transparency.

Recommendations

  1. Publish a clear Terms of Service page to improve legal compliance and user trust.
  2. Develop and publish a dedicated security policy and incident response contact information.
  3. Implement a vulnerability disclosure policy and provide a security.txt file for transparency.
  4. Enhance website accessibility features to meet broader compliance and usability standards.
  5. Provide clear and accessible contact information including emails and phone numbers for customer support.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, indicating a stable technical foundation. The inclusion of modern JavaScript libraries such as jQuery Mousewheel and integration with Google Tag Manager and Cookiebot reflects a mature digital infrastructure. Performance is moderate, with asynchronous loading of scripts and preconnect hints to optimize resource fetching. SEO is well supported through meta tags, Open Graph, and Twitter cards. Mobile optimization is good, with responsive viewport settings and adaptive design. Technical risks are minimal, though reliance on multiple third-party tracking services requires ongoing monitoring for privacy compliance and security. Opportunities exist to improve accessibility and to formalize security and privacy documentation to reduce technical debt and compliance risks.
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.
