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

TOMEGAS s.r.o. is a Czech company specializing in the supply of liquefied gases, ecological heating solutions, and propane-butane gas bottles, serving both businesses and households. The company positions itself as a traditional and established player in the Czech energy market with over 25 years of history. Their key services include turnkey solutions for propane gas tanks, ecological heating installations, and a network of LPG autogas stations. The website reflects a mature digital presence with comprehensive content, certifications, and multiple contact channels. Technically, the site is built on WordPress with common industry-standard plugins and tracking tools, showing moderate performance and good mobile optimization. Security posture is adequate with HTTPS and CAPTCHA protections, but lacks some advanced security headers and published incident response policies. Privacy compliance is strong with GDPR-aligned cookie consent mechanisms. The absence of WHOIS data is a notable gap, reducing domain registration trustworthiness, but the overall business credibility remains high based on website content and certifications.

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. 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"

      • 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

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, focusing on LPG and ecological heating solutions. Their business model revolves around supplying gas products and related services to both commercial and residential customers. The presence of ISO 9001 and ISO 14001 certifications indicates a commitment to quality and environmental management. The website's content and references to over 1000 installations and 1200+ distribution points suggest a significant market footprint in the Czech Republic. The company leverages digital marketing and analytics tools extensively, indicating a strategic approach to customer engagement and growth. Social media presence on Facebook and Instagram supports brand visibility. The lack of WHOIS transparency is a potential risk factor but does not currently impact operational credibility.

Security posture

The website enforces HTTPS and integrates hCaptcha for form security, which are positive security measures. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options indicates room for improvement in mitigating common web vulnerabilities. No visible vulnerabilities or exposed sensitive data were detected. The cookie consent mechanism is robust and GDPR compliant, reflecting good privacy practices. The site lacks a published security policy or incident response contact, which could hinder effective vulnerability reporting and incident management. Overall, the security posture is moderate but could be enhanced by implementing recommended headers and formalizing security policies.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Publish a formal security policy and incident response contact information to improve transparency and readiness.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly audit and update third-party scripts and plugins to mitigate potential vulnerabilities.
  5. Enhance WHOIS data transparency or investigate the cause of missing WHOIS information to improve domain trust.

Technical notes

Notes

The website is built on WordPress CMS, utilizing jQuery and several third-party analytics and marketing scripts such as Google Analytics, Hotjar, Adform, and Leady. The site includes a cookie consent banner with granular user controls, indicating compliance with privacy regulations. Performance is moderate with good mobile responsiveness and basic accessibility features. The site uses hCaptcha for bot protection on forms. There is no indication of advanced frameworks beyond WordPress and common plugins. Hosting provider details are not evident from the data. The site structure and SEO metadata are well implemented, supporting good search engine visibility. Opportunities exist to improve security headers and accessibility compliance to reduce technical debt and enhance user trust.
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.
