With over 25 years of experience, it serves both business clients and the public for construction sites, cultural, sports, and social events primarily in the Czech Republic and neighboring countries. The company positions itself as a market leader with a comprehensive product portfolio and additional services such as express delivery through its GO1 platform. Technically, the website is built on Joomla CMS with VirtueMart e-commerce components, leveraging modern JavaScript libraries like jQuery and integrating marketing and analytics tools such as Google Tag Manager and Seznam.cz tracking. The site is mobile-optimized and provides a good user experience with clear navigation and professional design. Privacy and cookie policies are implemented with consent mechanisms, reflecting GDPR compliance. From a security perspective, the site uses HTTPS and has basic security best practices in place, though explicit security policies and incident response details are not publicly available. No critical vulnerabilities or exposed sensitive data were detected.

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

6 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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

  3. 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.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 event and construction support sector, providing essential infrastructure solutions such as mobile toilets and containers. Its business model focuses on rental and sales, supported by a strong logistics network including express delivery. The target customers include construction firms, event organizers, and private individuals hosting social events. The company leverages partnerships and subsidiaries (GO1 platforms) to expand service reach. Certifications like ISO 9001, 14001, and 45001 reinforce its quality and environmental management credentials. The website content and marketing efforts indicate a focus on reliability, convenience, and customer service, positioning JOHNNY SERVIS as a trusted provider in Central Europe.

Security posture

The website exhibits a moderate to good security posture with HTTPS enforced and cookie consent implemented. Use of third-party analytics and marketing tools is transparent, and no sensitive data leakage was observed. However, the lack of visible security headers and absence of published security policies or incident response contacts represent gaps. The missing WHOIS data for the domain is a concern for domain legitimacy verification. Overall, the security maturity is adequate for the business type but could be improved by adopting additional security best practices and transparency measures.

Recommendations

  1. Implement and verify HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response contact information on the website to improve transparency and preparedness.
  3. Regularly audit and update third-party libraries and plugins to mitigate potential vulnerabilities.
  4. Investigate and resolve the missing WHOIS data issue to ensure domain registration legitimacy and improve trust.
  5. Enhance accessibility features and conduct periodic security assessments to maintain compliance with evolving standards.

Technical notes

Notes

The website uses Joomla CMS with VirtueMart for e-commerce functionality, supported by jQuery and other JavaScript libraries. It integrates Google Tag Manager and Seznam.cz tracking for analytics and marketing. The site is mobile responsive with good SEO metadata and Open Graph tags. Performance is moderate, with room for optimization. The presence of cookie consent and privacy policy indicates compliance maturity. No hosting provider details were found. Technical debt appears low, but security header implementation and WHOIS data availability are areas for improvement.
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.
