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

The website www.alkohol-tester.biz operates as a specialized e-commerce platform focused on selling branded and certified alcohol testers and drug testing devices primarily to consumers and small to medium businesses in the Czech Republic and Slovakia. It offers a broad product range with detailed descriptions, calibration services, and customer support, positioning itself as a trusted niche retailer with over 3000 units sold. The business emphasizes product authenticity and after-sales service, including calibration and repair. Technically, the site uses standard web technologies including HTML, CSS, JavaScript, Google Analytics, and Zopim live chat. However, it still contains deprecated Flash content and lacks modern security headers, which could impact user experience and security. The site is accessible over HTTPS but does not provide a comprehensive privacy policy, though it has a cookie consent mechanism. Contact information is clearly presented, enhancing business credibility. WHOIS data is completely missing, which reduces transparency and trustworthiness from a domain registration perspective. Overall, the site is functional and content-rich but would benefit from technical and security improvements.

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. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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 business operates in the retail sector, specializing in alcohol and drug testing devices. It targets individual consumers, families, and small to medium enterprises requiring reliable testing solutions. The company, identified as V-Net s.r.o., holds registered trademarks for its product lines and emphasizes product certification and service quality. The business model is direct e-commerce sales with value-added services such as calibration and repair. The website references partner and sister e-shops in related automotive and safety product niches, indicating a small network of related businesses. The market position is that of a trusted niche player with a moderate online presence. Revenue streams likely derive from product sales and service contracts. The company maintains a customer advisory approach to assist buyers in selecting appropriate devices. Growth indicators include a stable product range and ongoing customer engagement via newsletters and live chat support.

Security posture

The website demonstrates a basic security posture with HTTPS enabled, which is mandatory for secure communications. However, it lacks advanced security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options, which are recommended to mitigate common web vulnerabilities. The presence of deprecated Flash content poses a security and compatibility risk. No explicit security or incident response policies are published, and no vulnerability disclosure or security.txt files are found. The site does not expose sensitive data in the HTML, and forms appear to be minimal and standard. Overall, the security maturity is basic, suitable for a small e-commerce site but with room for improvement to enhance protection and compliance.

Recommendations

  1. Implement modern security headers including CSP, HSTS, and X-Frame-Options to improve site security.
  2. Remove or replace deprecated Flash content to enhance compatibility and reduce security risks.
  3. Publish a comprehensive privacy policy page detailing data collection, processing, and user rights to improve GDPR compliance.
  4. Enhance mobile responsiveness and accessibility to improve user experience across devices.
  5. Establish and publish incident response and vulnerability disclosure policies to build trust and readiness.

Technical notes

Notes

The website uses a traditional HTML/CSS/JavaScript stack with some legacy technologies such as Flash, which is outdated and unsupported by modern browsers. It integrates third-party services including Google Analytics for tracking and Zopim for live chat support. The site lacks a modern CMS or framework indication and appears to be custom-built or using a basic template. Performance is moderate with no explicit optimization for mobile devices, and accessibility features are minimal. SEO is basic with meta tags present but no structured data or Open Graph tags detected. Hosting provider details are not discernible from the content. The site would benefit from modernization efforts including responsive design, removal of deprecated technologies, and improved technical SEO and accessibility 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.
