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

JAZNAK spol. s r.o. is a Czech company specializing in the production, installation, and maintenance of traffic signage primarily in the Mladá Boleslav district. Established in 2006, the company offers a comprehensive range of services including permanent and temporary traffic signs, traffic mirrors, and signal systems with a 24/7 service model. The company holds an ISO 9001:2016 quality certification, underscoring its commitment to quality and customer satisfaction. The website reflects a regional business with a clear focus on B2B clients in the transportation sector. Technically, the website is built on WordPress using the Divi theme, leveraging common web technologies such as jQuery and Font Awesome. The site is hosted via a CDN linked to the registrar REG-INTERNET-CZ, ensuring moderate performance and good mobile optimization. SEO and accessibility are adequately addressed, though there is room for improvement in security headers and privacy documentation. From a security perspective, the site enforces HTTPS and implements a cookie consent banner, indicating basic compliance with privacy regulations. However, it lacks explicit privacy and security policies, security.txt files, and advanced security headers. No vulnerabilities or suspicious activities were detected, and the domain registration data aligns well with the business claims, indicating legitimacy and trustworthiness. Overall, the website presents a professional and trustworthy digital presence for a small regional transportation signage company. Strategic improvements in privacy policy publication, security header implementation, and vulnerability disclosure would enhance compliance and 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

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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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"

    • 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

The company operates in the transportation sector, focusing on traffic signage solutions. Its competitive advantage lies in its flexibility and personalized customer service, contrasting with larger firms. The business model is B2B, targeting investors and contractors in the Mladá Boleslav region. Revenue streams likely include sales, installation, rental, and maintenance services. The company maintains a partnership with Online Star, s.r.o. for web hosting or digital services. Growth indicators include a longstanding domain and ISO certification. The company’s market position is that of a trusted regional specialist with a quality certification, serving a niche market with specialized products and services.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is properly configured, and a cookie consent mechanism is in place, supporting GDPR compliance. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and others reduces the overall security posture. No incident response or security contact information is provided, which could hinder vulnerability reporting and response. The lack of a published privacy policy and terms of service is a compliance gap. No known vulnerabilities or exposed sensitive data were detected. The site would benefit from enhanced security practices and documentation to improve trust and compliance.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages to improve legal compliance and user trust.
  2. Implement security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to harden the website against common attacks.
  3. Create and publish a security.txt file to facilitate responsible vulnerability disclosure and incident response.
  4. Regularly audit and update WordPress plugins and themes to mitigate risks from vulnerable components.
  5. Enhance accessibility features and provide clear data retention policies to align with best practices and regulations.

Technical notes

Notes

The website is built on a mature CMS platform (WordPress) with the Divi theme, which provides flexibility and ease of content management. The use of Google Fonts and Font Awesome enhances visual appeal. Hosting via a CDN improves content delivery performance. The site is mobile optimized and SEO friendly with proper meta tags and structured data (JSON-LD). However, the site lacks advanced security headers and some accessibility features. Performance is moderate, with potential improvements in caching and resource optimization. The technical stack is standard for small business websites, with opportunities to modernize security and privacy implementations.
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.
