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

DANSGAS s.r.o. is a Czech company specializing in the sale and distribution of liquefied petroleum gases (LPG) including propane, butane, and propane-butane mixtures. With over 20 years of market presence, the company has established a stable position emphasizing professionalism, quality service, and competitive pricing. Their offerings include LPG sales, technical gases, gas tanks, safety consulting, and equipment rental, targeting both businesses and individual consumers in the energy sector. Technically, the website employs modern frontend technologies such as jQuery, Materialize CSS, and FontAwesome, providing a responsive and user-friendly experience. The site includes a cookie consent mechanism compliant with EU regulations, though no explicit privacy policy or terms of service pages were found. Performance is moderate with good mobile optimization, but accessibility and SEO could be improved. From a security perspective, the site uses HTTPS and basic anti-spam measures on its contact form but lacks advanced security headers and visible incident response or security policies. The absence of WHOIS data for the domain reduces trust from a domain registration standpoint, though the website content and contact information appear legitimate and professional. Overall, the website is functional and professional but would benefit from enhanced security practices, clearer privacy documentation, and domain registration transparency to improve trust and compliance.

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

11 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

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      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

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

DANSGAS s.r.o. operates in the energy sector focusing on LPG sales and related services. Their competitive advantage lies in over two decades of experience, a broad product range, and positive partner relationships. The business model centers on direct sales, equipment rental, and safety consulting, targeting both commercial and private customers. The company leverages EU financial support for operational improvements, indicating active growth and investment. The website reflects a stable, small-sized enterprise with consistent branding and clear communication channels. Partnerships with web service providers like esluzby.net support their digital presence, though no broader partnership ecosystem is evident from the site.

Security posture

The current security posture is moderate. The website uses HTTPS, which is mandatory, and includes basic anti-spam measures on its contact form. However, it lacks critical security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options, which are important for mitigating common web vulnerabilities. No incident response or security policy information is provided, and no vulnerability disclosure or security.txt files are present. The absence of WHOIS data raises concerns about domain registration transparency. Overall, while no critical vulnerabilities are apparent, the site would benefit from enhanced security controls and documentation to improve its security maturity and compliance with GDPR and other regulations.

Recommendations

  1. Implement and enforce HTTP security headers including CSP, HSTS, and X-Frame-Options to strengthen web security.
  2. Publish a clear and comprehensive privacy policy and terms of service to improve transparency and GDPR compliance.
  3. Add CAPTCHA or other advanced anti-spam mechanisms to the contact form to reduce spam and abuse risks.
  4. Investigate and resolve the missing WHOIS data issue to improve domain registration trustworthiness.
  5. Establish and communicate an incident response policy and vulnerability disclosure process to enhance security posture and stakeholder trust.

Technical notes

Notes

The website uses a modern frontend technology stack including jQuery, Materialize CSS framework, FontAwesome icons, and Slick carousel for UI components. The site is mobile responsive and includes cookie consent functionality compliant with EU regulations. Performance is moderate with no major errors detected. However, the site lacks advanced SEO optimizations and accessibility features. There is no detected CMS or hosting provider information. The technical debt appears low but updating third-party libraries and adding security headers would reduce risks. The site’s infrastructure supports the business needs but could be improved for better security and 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.
