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

Trefal s.r.o. is a Czech Republic-based manufacturing company specializing in industrial washing machines, custom stainless steel products, and sheet metal part production cooperation. The company targets industrial and manufacturing clients, offering modular and custom solutions with a focus on quality and technological innovation. Their website reflects a professional presence with clear product categories and service offerings, supported by social media engagement on Facebook and LinkedIn. Technically, the website is built on Joomla CMS using the YOOtheme framework and Uikit CSS, incorporating modern web technologies and responsive design. It employs several third-party scripts for analytics and marketing, including Google Tag Manager, Facebook Pixel, LinkedIn Insight, and Cookiebot for cookie consent management. The site supports secure login with WebAuthn, enhancing authentication security. From a security perspective, the site enforces HTTPS and uses secure login mechanisms but lacks explicit security headers such as Content-Security-Policy and X-Frame-Options. No vulnerabilities or exposed sensitive data were detected in the content. Privacy compliance is partially addressed with a cookie consent banner, but no dedicated privacy policy or terms of service pages were found. WHOIS data is missing, which slightly reduces domain trustworthiness. Overall, the website is well-structured, professional, and secure for its business purpose, though improvements in privacy documentation and security headers are recommended to enhance compliance and 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

8 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  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 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';…

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

Trefal s.r.o. operates in the manufacturing sector with a focus on industrial washing machines and metal fabrication. The company appears to have a medium-sized operation with a regional market presence in the Czech Republic. Their business model includes both standard product lines and custom manufacturing tailored to client needs. The website content and social media presence indicate active engagement with industrial clients. The absence of WHOIS data is a minor concern but does not detract significantly from the company's apparent legitimacy. The company leverages digital marketing and analytics tools to support growth and customer insights.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and support for advanced authentication via WebAuthn. However, the lack of security headers and absence of a published security policy or incident response contacts indicate areas for improvement. No critical vulnerabilities or exposed sensitive information were found. The cookie consent mechanism aligns with GDPR requirements, but the missing privacy policy and terms of service pages represent compliance gaps. Overall, the security maturity is adequate for the business size but could be enhanced with additional controls and transparency.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen protection against common web attacks.
  3. Provide clear incident response contact information and consider publishing a security policy to demonstrate commitment to security.
  4. Regularly review and update third-party scripts and tracking tools to minimize security risks and ensure privacy compliance.
  5. Consider obtaining and displaying relevant industry certifications or trust badges to enhance business credibility.

Technical notes

Notes

The website is built on a mature CMS platform (Joomla) with a modern front-end framework (YOOtheme and Uikit), supporting responsive design and accessibility features. Performance is moderate, with optimized images and asynchronous loading of scripts. The use of structured data (JSON-LD) improves SEO and content discoverability. The site integrates multiple analytics and marketing tools, indicating a data-driven approach. However, the absence of some security headers and incomplete privacy documentation highlight technical debt and compliance risks that should be addressed to maintain operational integrity and trust.
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.
