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

H&M spol. s r.o. is a well-established family-owned manufacturing and retail company based in the Czech Republic, specializing in custom plastic, aluminum, and wooden windows and doors, as well as winter gardens and shading technology. The company holds a strong market position with over 100 references and a notable showroom in Prague, targeting residential and commercial customers seeking high-quality custom products. The website reflects a professional business model focused on manufacturing and retail within the construction and home improvement sectors. Technically, the website employs modern tracking and marketing tools such as Google Tag Manager, Facebook Pixel, and Seznam tracking scripts, alongside a cookie consent mechanism indicating GDPR awareness. The site is mobile-optimized with good SEO practices and a moderate performance profile. However, no CMS or hosting provider details were detected, and accessibility features are basic. From a security perspective, the site uses HTTPS with good SSL configuration but lacks explicit security headers and published security policies or incident response contacts. No vulnerabilities or exposed sensitive data were found, but recommendations include implementing security headers and publishing a vulnerability disclosure policy to enhance security posture. Overall, the website is trustworthy, professionally designed, and compliant with basic privacy and cookie regulations. The domain WHOIS data confirms a long-standing registration consistent with the company's history, supporting legitimacy. Strategic improvements in security transparency and compliance documentation would further strengthen the company's digital maturity 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

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

    • 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

H&M spol. s r.o. operates in the manufacturing and retail sectors, focusing on custom windows, doors, and related construction products. The company leverages a family-owned business model with a strong local presence in the Czech Republic, supported by a showroom and multiple contact channels. Their competitive advantage lies in product quality, customization, and a broad product portfolio including plastic, aluminum, and wooden solutions, as well as shading and pergola systems. Revenue streams likely derive from direct sales and installation services. The target customer segments include homeowners, builders, and commercial clients. The company maintains a partnership ecosystem with suppliers and possibly local distributors, though no explicit partner domains were identified. Growth indicators include recent promotions and active content updates. The website content and structure support a professional market presence with consistent branding and customer engagement.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and use of secure tracking scripts loaded asynchronously. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap in defense-in-depth. No explicit security or incident response policies are published, limiting transparency and preparedness communication. Data protection practices include cookie consent mechanisms, but GDPR compliance could be improved with clearer privacy policy documentation and data retention disclosures. No vulnerabilities or exposed sensitive data were detected in the HTML content. Incident response readiness is unknown due to lack of contact channels for security issues. Overall, the security posture is adequate for a medium-sized manufacturing business but would benefit from enhanced policy publication and technical hardening.

Recommendations

  1. Implement and configure HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  2. Publish a dedicated security policy and incident response contact information on the website to increase transparency and readiness.
  3. Add a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance privacy compliance by providing a clear, accessible privacy policy page detailing data processing and retention practices.
  5. Regularly audit third-party scripts and tracking tools to ensure they comply with privacy regulations and do not introduce vulnerabilities.

Technical notes

Notes

The website uses a modern technology stack with Google Tag Manager, Facebook Pixel, and Seznam tracking scripts for analytics and marketing. It loads fonts from Google Fonts and employs a cookie consent script from cookie-script.com. The HTML is well-structured with responsive design elements and mobile optimization. No CMS or hosting provider was identified, suggesting a custom or proprietary platform. Performance is moderate with asynchronous loading of scripts. Accessibility features are basic but present. SEO is supported by meta tags and structured navigation. Technical risks include missing security headers and lack of explicit CMS or platform updates, which could impact long-term maintainability and security.
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.
