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

JASS a. s. is a Czech joint-stock company specializing in manufacturing electric overhead cranes, crane runways, and related crane components. With over 30 years of experience, the company serves industrial clients requiring material handling and lifting solutions. Their product portfolio includes overhead cranes, portal cranes, slewing column cranes, light crane systems, and special custom manufacturing. The website is professionally designed, providing clear navigation, contact information, and references, indicating a well-established business presence. Technically, the site uses modern JavaScript libraries, Google Analytics, and a cookie consent management system, reflecting a moderate level of digital maturity. Security-wise, the site implements cookie consent and uses HTTPS (assumed), but lacks visible security headers and explicit security policies, suggesting room for improvement. The absence of WHOIS data for the domain raises concerns about domain registration legitimacy, though the website content and contact details appear authentic. Overall, the site presents a credible industrial manufacturing business with moderate technical 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

5 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, Google APIs, Google Ads

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

  2. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

JASS a. s. operates in the manufacturing and transportation sectors, focusing on crane production and installation services. Their market positioning is supported by decades of experience and a comprehensive product range. The business model centers on manufacturing, sales, installation, and after-sales service. The target customers are industrial and logistics companies requiring lifting and material handling equipment. The website's references and contact channels indicate active client engagement. The company appears medium-sized with consistent branding and good content quality. Partnerships with technology providers like CS Technologies for website development are evident. The lack of WHOIS transparency is a notable risk factor but does not currently undermine operational credibility.

Security posture

The website demonstrates basic security awareness through cookie consent and GDPR compliance. However, the absence of visible HTTP security headers (such as Content-Security-Policy, X-Frame-Options, and HSTS) and no published security or incident response policies indicate a moderate security maturity level. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party scripts like Google Analytics and CookieYes is standard but requires ongoing monitoring for vulnerabilities. The missing WHOIS data is a concern for domain legitimacy and could be a risk factor if the domain is not properly registered or maintained. Overall, the security posture is adequate but could be enhanced with stronger technical controls and transparency.

Recommendations

  1. Implement and verify HTTP security headers including CSP, HSTS, and X-Frame-Options to improve protection against common web attacks.
  2. Ensure SSL/TLS certificates are properly configured and up to date to maintain secure communications.
  3. Publish explicit security policies and incident response procedures on the website to enhance transparency and preparedness.
  4. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  5. Investigate and resolve the missing WHOIS data issue to improve domain legitimacy and trustworthiness.

Technical notes

Notes

The website uses a custom or proprietary CMS framework (EwCore) with modern JavaScript libraries such as jQuery, Magnific Popup, and Blazy for lazy loading images. Google Tag Manager and Google Analytics are integrated for tracking and analytics. CookieYes is used for cookie consent management, providing detailed user controls. The site is mobile responsive with good navigation and SEO meta tags. Performance is moderate, with some lazy loading optimizations. Accessibility is basic but present. No hosting provider or SSL certificate details were found in the HTML content. Overall, the technical infrastructure is solid but could benefit from enhanced security headers and performance tuning.
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.
