Risk levelMedium

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

puren gmbh is a German manufacturing company specializing in high-performance polyurethane rigid foam insulation products. Their website showcases a broad product portfolio targeting architects, planners, trade professionals, industry OEMs, private builders, and the housing sector. The company emphasizes sustainability and energy efficiency in construction. Technically, the website is built on TYPO3 CMS, employs modern web technologies, and includes GDPR-compliant privacy and cookie consent mechanisms. The site is well-structured, mobile-optimized, and professionally designed, reflecting a mature digital presence. Security posture is generally good with HTTPS enforced and secure session management, though the absence of security headers and a public security policy are areas for improvement. The WHOIS data is missing or unavailable, which raises concerns about domain registration transparency, but the website's comprehensive contact information and social media presence support its legitimacy. Overall, the site scores well on content quality, technical implementation, privacy compliance, and business credibility, with recommendations to enhance security headers and publish incident response information.

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 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. 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

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

puren gmbh operates in the manufacturing sector, focusing on PU insulation materials that contribute to energy saving and climate protection. Their business model includes product manufacturing, custom solutions, and providing technical documentation and support. The company targets multiple customer segments including construction professionals and private builders, indicating a diversified market approach. The website's multilingual support and extensive product information suggest a medium-sized enterprise with a solid market position in Germany and potentially broader European markets. The presence of certifications and references indicates a focus on quality and trust-building. The company maintains active social media channels, enhancing brand visibility and customer engagement. The lack of WHOIS transparency is a minor risk factor but does not currently undermine the business's operational credibility.

Security posture

The website enforces HTTPS and uses secure session cookies, which are positive security indicators. It implements a comprehensive cookie consent mechanism aligned with GDPR requirements, reflecting good privacy practices. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection reduces the overall security posture. No public security policy or incident response contact information is available, which limits transparency and readiness perception. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party analytics (eTracker) is managed with user consent, supporting privacy compliance. Overall, the security maturity is moderate with room for improvement in headers and incident response visibility.

Recommendations

  1. Implement standard security headers (Content-Security-Policy, X-Frame-Options, X-XSS-Protection) to enhance protection against common web attacks.
  2. Publish a clear security policy and provide incident response contact details to improve transparency and trust.
  3. Verify and update WHOIS registration information to ensure domain legitimacy and reduce suspicion.
  4. Continue maintaining GDPR compliance with clear cookie consent and privacy policies.
  5. Regularly audit third-party scripts and analytics to minimize privacy risks and ensure compliance.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust open-source content management system, indicating a mature technical infrastructure. It uses modern CSS and JavaScript assets, including asynchronous loading of analytics scripts, which supports performance optimization. The site is mobile-optimized with responsive images and viewport settings. SEO is enhanced by meta tags, canonical URLs, hreflang attributes for multilingual support, and structured data in JSON-LD format. The presence of a search form and clear navigation menus improves usability. No major technical debt or outdated libraries were detected. Hosting provider details are not explicitly available. Performance is moderate, with potential for further optimization. Accessibility features appear adequate but could be further audited for compliance with standards.
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.
