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

Strømmen Group is a Norwegian manufacturing company specializing in the production, delivery, and installation of exclusive windows, folding doors, sliding doors, and glass facades made from wood and aluminum. The company targets customers primarily in Norway and the Scandinavian region, offering a showroom experience to showcase their products. The website is built on Drupal 10, indicating a modern and maintainable technical infrastructure. It integrates multiple analytics and marketing tools such as Google Analytics, Hotjar, and Cookiebot, demonstrating a mature digital marketing approach. Security posture is generally good with HTTPS enforced and cookie consent mechanisms in place, but lacks visible security headers and explicit security policies. The absence of WHOIS registration data is a notable concern, potentially indicating domain registration issues or privacy protection, which warrants further investigation. Overall, the website presents a professional and trustworthy front with room for improvement in security transparency and contact information availability.

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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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

  3. 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';…

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

Strømmen Group operates in the manufacturing sector with a niche focus on high-quality window and door products. Their business model combines manufacturing with direct customer engagement through a physical showroom. The company leverages digital marketing and analytics tools to optimize customer reach and engagement. The lack of WHOIS data is unusual and may impact trust perceptions. No partnerships or subsidiaries are explicitly identified from the website content. The company appears to maintain consistent branding and provides comprehensive privacy and cookie policies, aligning with GDPR requirements. Growth potential is supported by a clear product offering and regional focus.

Security posture

The website enforces HTTPS and uses a cookie consent mechanism compliant with GDPR, reflecting a good baseline security and privacy posture. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces the overall security robustness. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. The lack of explicit incident response or security policy pages and no security.txt file indicates limited transparency in security governance. The extensive use of third-party analytics and marketing scripts requires ongoing vigilance to mitigate supply chain risks. Overall, the security posture is moderate with clear opportunities for enhancement.

Recommendations

  1. Implement and publish security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Publish explicit security policies and incident response contact information to improve transparency and trust.
  3. Verify and update WHOIS registration data to ensure domain legitimacy and reduce suspicion.
  4. Add clear and accessible company contact information including emails and phone numbers for customer and security inquiries.
  5. Conduct regular audits of third-party scripts and cookies to ensure compliance and minimize privacy risks.

Technical notes

Notes

The website is built on Drupal 10, a modern and widely supported CMS platform, ensuring maintainability and security updates. It uses standard web technologies including HTML5, CSS3, and JavaScript, with integration of Google Analytics, Hotjar, and Cookiebot for analytics and consent management. The site is mobile optimized and includes SEO best practices such as canonical links and meta descriptions. Performance is moderate, with room for optimization. No hosting provider details were identified from the content. Accessibility features are basic and could be improved to meet higher standards. Overall, the technical infrastructure is solid but could benefit from enhanced security configurations and accessibility 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.
