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

5 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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 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. 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 · found on this site
  • 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 manufacturing sector, focusing on high-end building materials for the construction industry. Its business model revolves around manufacturing and direct sales, supported by qualified engineering services. The website content and metadata indicate a clear market positioning emphasizing quality and innovation. The use of multiple languages and regional URLs suggests a European market focus, particularly Lithuania and neighboring countries. The absence of explicit contact details on the main page may indicate a preference for controlled lead generation or B2B sales channels. The integration of marketing and analytics tools reflects a data-driven approach to customer engagement and market analysis. No partner or subsidiary domains were identified, indicating a standalone operational structure.

Security posture

The website employs HTTPS with a good SSL configuration, ensuring encrypted communications. Cookie consent is actively managed via Cookiebot, reflecting compliance with privacy regulations. However, the lack of DNSSEC and missing security headers such as Content-Security-Policy and X-Frame-Options reduce the overall security robustness. No exposed sensitive data or vulnerable libraries were detected in the provided content. The use of third-party scripts from trusted providers like Google and Hotjar is balanced with user consent mechanisms. Incident response and security policy information are not publicly available, which could be a gap in transparency and preparedness. Overall, the security posture is moderate to good but could benefit from enhanced DNS security and HTTP header hardening.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve domain security.
  2. Implement standard security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to harden HTTP responses.
  3. Publish a clear security policy and incident response contact information to improve transparency and trust.
  4. Review and audit third-party scripts regularly to mitigate risks from external dependencies.
  5. Enhance accessibility features and provide clearer contact information to improve user trust and engagement.

Technical notes

Notes

The website is powered by Drupal 10, a modern and widely supported CMS, ensuring a solid technical foundation. It uses Google Fonts for typography and integrates analytics and marketing tools such as Google Analytics, Hotjar, and Cookiebot for user tracking and consent management. The site is mobile-optimized with responsive design and includes SEO best practices like canonical links and meta descriptions. Performance is moderate, with asynchronous loading of scripts to improve page load times. Hosting appears stable with DNS servers located in Lithuania, consistent with the business location. Technical debt appears low, but the absence of DNSSEC and security headers indicates room for modernization in security practices. Overall, the technical infrastructure supports business operations effectively with opportunities for incremental improvements.
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.
