Risk levelMedium

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

Triangel spol. s r.o. is a Czech company specializing in the supply of ventilated facades and cladding materials including brick, ceramic, stone, glass, and photovoltaic facades. Established in 1999, the company serves construction professionals and developers with a broad portfolio of facade solutions. The website reflects a small but established business with a clear focus on facade systems and related products. Technically, the website uses standard web technologies such as jQuery and Google Analytics, hosted on a Czech hosting provider. The site is accessible, with basic mobile optimization and navigation clarity. Security posture is moderate with HTTPS implied but lacks advanced security headers and published security policies. Privacy compliance is limited due to the absence of a privacy policy and terms of service, though a cookie consent banner is present. Overall, the domain registration data aligns well with the business information, supporting legitimacy and trustworthiness.

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

7 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

    • 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 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

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 real estate and manufacturing sectors, focusing on ventilated facade systems and cladding materials. Its business model is B2B, targeting architects, builders, and developers. The domain age of over 20 years indicates a stable market presence. The website content and navigation are consistent with a professional supplier, though content depth is basic. There is no evidence of partnerships or subsidiaries from the website data. The company provides multiple facade types including innovative photovoltaic facades, indicating a degree of product diversification. The lack of published certifications or security policies suggests room for maturity in compliance and trust-building measures.

Security posture

The website employs HTTPS and cookie consent mechanisms, indicating baseline security awareness. However, no security headers such as Content-Security-Policy or X-Frame-Options were detected, which are recommended to mitigate common web vulnerabilities. No vulnerability disclosure or incident response information is published, limiting transparency. The use of Google Analytics and Tag Manager introduces moderate user tracking, but no explicit data retention or privacy compliance details are provided. Overall, the security posture is moderate but could be improved by implementing security best practices and publishing relevant policies.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve GDPR compliance and user trust.
  2. Implement security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Establish and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance cookie consent mechanism to ensure explicit and granular user consent in line with GDPR requirements.
  5. Regularly review and update SSL/TLS configurations to maintain strong encryption standards and prevent vulnerabilities.

Technical notes

Notes

The website uses a simple technology stack with jQuery 3.2.1, cookie management scripts, and Google Analytics for tracking. Fonts are loaded from Google Fonts. The hosting provider is likely Websupport.cz based on nameservers. The site has a basic but functional design with clear navigation and mobile responsiveness at a basic level. No CMS or advanced frameworks were detected. Performance is moderate with no explicit indicators of optimization or technical debt. Accessibility features are minimal but present. SEO is basic with meta tags for description and keywords but no structured data or Open Graph tags found.
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.
