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

The website www.skladova-okna.cz is an established e-commerce platform operated by TT HOLDING, a.s., specializing in the sale of new plastic windows and doors primarily in the Czech Republic and neighboring countries. The company positions itself as a significant player with a large warehouse and showroom, offering both stock and custom-configured products. The site provides comprehensive product information, customer testimonials, and technical support including installation guides, reflecting a mature digital presence. Technically, the website employs modern web technologies including jQuery, Google reCAPTCHA v3, Google Tag Manager, and the OMNIX CMS platform. It demonstrates good performance, mobile optimization, and accessibility standards. Security measures such as HTTPS and CAPTCHA are implemented, though some HTTP security headers and incident response disclosures are absent. From a security and compliance perspective, the site includes a detailed privacy policy and cookie consent mechanism aligned with GDPR requirements. Contact information is clearly presented, and certifications such as APEK membership and verified customer reviews enhance trust. However, the absence of WHOIS data limits domain registration transparency, slightly impacting trustworthiness. Overall, the website is professional, secure, and user-friendly, serving a medium-sized business with a strong market position in retail and manufacturing of plastic windows and doors. Strategic improvements in security headers and incident response transparency are recommended to further strengthen its security posture.

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

  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

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

TT HOLDING, a.s. operates a multi-country e-commerce business focused on plastic windows and doors, targeting both professional installers and end consumers. The business model combines direct online sales of stocked products with a configurator tool for custom orders, enabling rapid delivery and competitive pricing. The company leverages its large warehouse and showroom in Kuřim, Czech Republic, to maintain market leadership. Partnerships and certifications, including APEK membership and presence on major review platforms, support its credibility. The company shows growth through extensive order volume and geographic reach across five countries. The website's integration with marketing and analytics tools indicates a data-driven approach to customer engagement and sales optimization.

Security posture

The website demonstrates a solid security foundation with HTTPS encryption, Google reCAPTCHA v3 integration to mitigate automated abuse, and a comprehensive cookie consent mechanism supporting GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of key HTTP security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. There is no publicly available security.txt or explicit incident response contact, which limits transparency for vulnerability reporting. Overall, the security posture is good but could be enhanced by implementing additional HTTP headers and formalizing incident response channels.

Recommendations

  1. Implement HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to strengthen browser security.
  2. Publish a security.txt file to provide clear vulnerability disclosure and incident response contact information.
  3. Add explicit incident response and abuse contact channels on the website to improve transparency and trust.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance privacy policy disclosures with detailed data retention and processing timelines to improve GDPR compliance.

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.
