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

Dřevo UM s.r.o. is a traditional Czech manufacturer specializing in wooden doors, euro-windows, staircases, and solid wood furniture. With over 25 years of experience, the company operates two workshops in České Budějovice and Heřmaň, serving both local and national markets. Their product range includes entrance and interior doors, wooden gates, windows, staircases, and custom furniture, complemented by services such as tool sharpening, wood drying, and impregnation. The company targets carpenters, construction firms, and end customers seeking quality wooden products. Technically, the website employs common JavaScript libraries like jQuery and Google Analytics for tracking, but lacks modern CMS or advanced frameworks. The site is moderately optimized for mobile and SEO, with a professional design and clear navigation. Security posture is average, with no visible security headers and unknown SSL status, and no privacy or cookie policies are published, indicating compliance gaps. WHOIS data confirms domain legitimacy and consistency with the business history. Overall, the website is functional and professional but would benefit from enhanced security and privacy compliance measures.

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

12 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"

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 holds a stable market position as a small manufacturing entity with a strong regional presence in southern Czech Republic and broader Czech markets. Its competitive advantage lies in its long-standing experience, diversified product portfolio, and integrated services for carpenters. Revenue streams likely derive from product sales and specialized services such as tool sharpening and wood treatment. The absence of social media presence and limited digital marketing tools suggests room for growth in online engagement. Partnerships include the web design studio QUIN.cz and SEO Rozcestník for marketing support. The business model focuses on craftsmanship and direct customer relationships, with potential to expand digital presence and compliance frameworks.

Security posture

The website demonstrates a basic security maturity level. While no critical vulnerabilities or exposed sensitive data are evident, the lack of HTTPS confirmation, absence of security headers, and missing privacy and cookie policies represent compliance and security weaknesses. The use of older JavaScript libraries is not inherently risky but should be monitored for updates. Incident response and vulnerability disclosure mechanisms are not present, limiting the company's readiness for security events. GDPR compliance is uncertain due to missing policies and consent mechanisms. Overall, the security posture is functional but requires improvements to meet modern standards and regulatory requirements.

Recommendations

  1. Implement HTTPS across the entire website to ensure secure communications.
  2. Publish comprehensive privacy and cookie policies aligned with GDPR requirements.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Establish and publish an incident response contact channel for security issues.
  5. Enhance mobile optimization and accessibility to improve user experience and compliance.

Technical notes

Notes

The website uses a traditional tech stack centered on jQuery and related plugins, with Google Fonts and Google Analytics integrated. The HTML structure is valid and includes meta tags for SEO. However, the site lacks modern CMS or frameworks, which may limit scalability and maintainability. Performance is moderate, with some responsiveness for mobile devices but basic optimization. The hosting and domain registration are stable and consistent with the business profile. Technical debt includes missing security headers and unclear SSL status, which should be addressed to improve security 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.
