The company is positioned as a B2B provider targeting energy sector businesses requiring advanced pipe solutions. The website reflects a professional digital presence with clear branding and relevant business content, supporting its market position.

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

4 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 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
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. 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

  3. Network security

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

    • 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

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 benefits from a clear market niche in the energy sector, focusing on district heating and cooling infrastructure. Its parent company is registered in Denmark, while the Finnish subsidiary operates the website, indicating a structured corporate presence in the Nordic region. The business model is B2B, supplying specialized pipe systems, which suggests stable revenue streams from industrial clients. The website's use of multiple languages and cookie consent mechanisms shows compliance with EU regulations. The lack of visible contact emails or phone numbers on the site may limit direct customer engagement but could be intentional for privacy or lead generation control. The company leverages major advertising and analytics platforms like Google and Meta for marketing and tracking, indicating a mature digital marketing strategy.

Security posture

The website enforces HTTPS and includes several security headers, reflecting good baseline security hygiene. The use of Cookiebot for cookie consent management supports GDPR compliance efforts. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a published security policy or incident response information reduces transparency for security-conscious visitors. The site uses common third-party scripts such as Google Tag Manager and Facebook Pixel, which should be regularly audited for security. Overall, the security posture is good but could be enhanced by publishing formal security and incident response policies and improving accessibility of contact channels for security issues.

Recommendations

  1. Publish a comprehensive privacy policy page clearly linked in the website footer.
  2. Add a terms of service page to clarify legal terms and user agreements.
  3. Provide visible contact information including company emails and phone numbers for customer and security inquiries.
  4. Develop and publish a security policy and incident response contact details to improve trust and compliance.
  5. Conduct regular security audits of third-party scripts and update accessibility features to meet compliance standards.

Technical notes

Notes

The website is built on WordPress CMS with Bootstrap framework and uses jQuery and QuadMenu for UI components. It integrates Cookiebot for cookie consent and Google Tag Manager for analytics and marketing. The site loads fonts via WOFF2 and uses minified CSS and JS for performance optimization. The presence of structured data (JSON-LD) enhances SEO and search engine understanding. Performance is moderate with good mobile responsiveness and basic accessibility features. The site uses a reputable registrar and stable DNS servers. No hosting provider details were explicitly found. Overall, the technical infrastructure is modern and well-implemented with opportunities to improve accessibility and privacy transparency.
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.
