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

Alkohol-tester.cz is a Czech e-commerce website specializing in the sale of certified alcohol testers, calibration, servicing, and drug testing products. Established since 2006, it serves both individual consumers and businesses requiring reliable alcohol detection devices. The website offers a range of products including personal, professional, and legally certified alcohol testers, supported by authorized calibration and repair services. The business positions itself as a trusted provider in the Czech market with a focus on quality and certification. Technically, the website uses standard web technologies such as jQuery and Font Awesome, with a custom or unknown CMS. The site is accessible without WAF or blocking mechanisms and provides clear contact information. However, it lacks privacy and cookie policies, security headers, and incident response information, which are areas for improvement. Overall, the website demonstrates moderate technical maturity and good business credibility but requires enhancements in security and privacy compliance to strengthen its 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

10 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

      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 operates in the retail sector, focusing on a niche market of alcohol testers and related accessories. Its business model is direct e-commerce sales supported by after-sales calibration and servicing, targeting both personal users and professional clients such as companies and government entities. The domain age of over 18 years supports its established market presence. The website content is professionally presented with detailed product information and trust signals like certification mentions. The absence of social media links and limited marketing tools suggests a focused but possibly limited digital marketing strategy. The company appears to maintain a stable position in the Czech market with a specialized product offering and a loyal customer base.

Security posture

The website currently lacks visible security headers and does not provide explicit information on security policies or incident response procedures. There is no evidence of GDPR compliance mechanisms such as privacy or cookie consent banners. The site uses HTTPS (implied by URL) but SSL configuration details are unknown. Forms are present but no advanced security measures or input validation details are visible. The absence of vulnerability disclosure or security.txt files indicates limited transparency in security practices. These gaps present moderate security risks and compliance challenges, especially regarding data protection regulations. Strengthening security headers, implementing privacy policies, and establishing incident response contacts are recommended to improve the security posture.

Recommendations

  1. Implement comprehensive privacy and cookie policies with user consent mechanisms to comply with GDPR.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  3. Publish incident response and vulnerability disclosure information, including security contact emails, to improve transparency and readiness.
  4. Conduct a security audit to identify and remediate any potential vulnerabilities in forms and input handling.
  5. Enhance digital marketing presence by integrating social media links and analytics tools with privacy compliance.

Technical notes

Notes

The website is built using common web technologies including jQuery and Font Awesome for UI elements, and Google Fonts for typography. The HTML structure is valid and includes appropriate meta tags for SEO and viewport settings for mobile responsiveness. However, the site lacks modern frameworks or CMS indicators, suggesting a custom or legacy platform. Performance is moderate with no explicit optimization techniques detected. Accessibility features are basic, and SEO is supported by meta descriptions and keywords. The site could benefit from modernization, including adoption of responsive frameworks, improved accessibility compliance, and enhanced performance optimization. Hosting provider details are not disclosed, limiting infrastructure assessment.
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.
