NAFTA is a leading Slovak international company specializing in the storage and development of underground natural gas reservoirs, as well as exploration and production of hydrocarbons. It holds a significant market position as the 6th largest gas storage operator in Europe, with operations extending beyond Slovakia into the Czech Republic, Germany, Austria, and Ukraine. The company offers a range of services including gas storage, innovative development projects, and support services in the energy sector. The website reflects a mature digital presence built on Drupal 10, featuring modern technologies and a professional design that supports business stakeholders and customers. Security measures such as HTTPS and security headers are well implemented, although some privacy compliance aspects like explicit cookie consent and incident response information could be improved. Overall, NAFTA demonstrates a strong security posture and credible business representation with comprehensive contact information and transparency.

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

3 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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

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

NAFTA's market positioning as a major European gas storage operator provides it with competitive advantages in Central Europe. Its business model focuses on energy storage and hydrocarbon exploration, targeting energy companies, regulators, and investors. The company maintains transparency through annual reports and ethical codes, supporting trust and compliance. Growth is indicated by innovative projects and regional expansion. The partnership ecosystem includes regional subsidiaries and customer zones, although no explicit partner domains were identified in the website content. NAFTA's operations are aligned with energy sector demands and regulatory frameworks in Slovakia and neighboring countries.

Security posture

The website exhibits a solid security maturity level with enforced HTTPS, presence of key security headers, and no visible exposure of sensitive data. However, the absence of a published incident response contact or vulnerability disclosure policy limits the company's readiness transparency. GDPR compliance is supported by a comprehensive privacy policy, but the lack of a cookie consent mechanism is a compliance gap. No vulnerable libraries or security flaws were detected in the analyzed content. The security culture appears professional but could benefit from enhanced communication of security policies and incident handling procedures.

Recommendations

  1. Implement an explicit cookie consent banner to improve GDPR compliance.
  2. Publish a clear terms of service page to enhance legal transparency.
  3. Add incident response contact details and consider a vulnerability disclosure policy or security.txt file.
  4. Enhance website accessibility features to meet higher standards.
  5. Maintain and regularly update security headers and SSL configurations.

Technical notes

Notes

The website is built on Drupal 10 CMS, leveraging modern front-end libraries such as Slick Carousel and SVG for graphics. Google Tag Manager is used for analytics and marketing tracking. The site is mobile optimized with responsive design and includes accessibility features, though these are basic. Performance is moderate, with potential for optimization. The technical infrastructure supports a professional corporate presence but could be improved with enhanced accessibility and faster load times. No technical debt or legacy technology indicators were found.
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.
