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"

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

GAZ-SYSTEM holds a key position in Poland's energy infrastructure as the national gas transmission system operator. Its business model revolves around managing and expanding gas transmission networks, operating LNG and FSRU terminals, and providing related services to clients and suppliers. The company maintains a strong partnership ecosystem visible through linked platforms and official social media channels. The presence of ESG reporting and transparency templates indicates a commitment to sustainability and regulatory compliance. The company targets large-scale energy market participants and governmental stakeholders. The website's content and structure support its role as a reliable and transparent operator in the energy sector.

Security posture

The website demonstrates a solid security foundation with HTTPS enabled and cookie consent implemented, supporting GDPR compliance. However, the absence of explicit security headers such as Content-Security-Policy and lack of publicly available security or incident response policies represent areas for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a security.txt or vulnerability disclosure page limits transparency for security researchers. Overall, the security posture is good but could be enhanced by adopting additional best practices and publishing incident response contacts.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy or incident response page with contact information to improve transparency and readiness.
  3. Add a security.txt file to facilitate vulnerability reporting and responsible disclosure.
  4. Enhance contact information availability on the website, including verified company emails and phone numbers for customer and security inquiries.
  5. Regularly audit third-party scripts and tracking tools to ensure no vulnerable or deprecated libraries are used.

Technical notes

Notes

The website is built on a custom CMS platform with modern front-end technologies including JavaScript and CSS. It uses Google Analytics and Google Tag Manager for analytics and marketing purposes. The presence of Swiper.js indicates interactive UI components such as sliders. The site is mobile responsive and includes accessibility features like contrast and font size adjustments. Performance is moderate, with room for optimization. The hosting provider is not explicitly identified. The site uses standard meta tags and Open Graph tags for SEO and social media integration. No critical technical debt or deprecated technologies were observed.
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.
