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

Vítkovice Cylinders, operating under Cylinders Holding, is a large industrial manufacturer specializing in steel cylinders, pressure tanks, accumulators, bundles, and gas storage systems. The company positions itself as the world's largest manufacturer in this sector, targeting industrial and energy clients. The website is built on the Wix platform, indicating a moderate level of digital maturity with standard web technologies and moderate performance. However, the site lacks visible contact information and formal privacy or cookie policies, which are important for compliance and user trust. Security posture is moderate with no detected security headers or incident response information, suggesting room for improvement in security best practices. Overall, the website presents a professional image but would benefit from enhanced transparency and security measures.

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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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';…

  3. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

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 energy sector with a manufacturing business model focused on supplying steel cylinders and related products for gas storage. Its market position as the largest manufacturer globally indicates strong competitive advantages and a significant market share. The website targets industrial clients and energy companies, but lacks detailed business information such as founding year or subsidiaries. The absence of visible contact details and policies may impact customer trust and regulatory compliance. The digital presence is functional but basic, with no advanced analytics or marketing tools detected.

Security posture

The current security maturity level is basic. The website uses HTTPS (implied by canonical URLs) but lacks visible security headers such as Content-Security-Policy or X-Frame-Options. No incident response or security contact information is provided. There is no evidence of GDPR compliance mechanisms like cookie consent banners or privacy policies. The absence of these elements represents compliance gaps and potential vulnerabilities. No vulnerable libraries or exposed sensitive data were detected in the provided content. The security score is moderate but improvements are needed to meet industry best practices and regulatory requirements.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance and consent mechanisms.
  2. Add visible and verified company contact information including emails and phone numbers for customer and security incident reporting.
  3. Configure and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Establish an incident response policy and publish security contact channels (e.g., security@ or abuse@ emails).
  5. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities and improve security posture.

Notes

The site lacks forms or interactive data collection elements in the provided content.
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.
