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

The Norwegian Seafarers Union (NSU) operates a professional and content-rich website serving as the official portal for the union representing maritime workers in Norway. The site provides comprehensive information about the union's activities, news, events, and support services for seafarers. It targets maritime professionals and union members, positioning itself as a trusted advocate for seafarers' rights and welfare. The website demonstrates a solid market presence within the transportation and non-profit sectors. Technically, the website employs modern web technologies including Bootstrap, jQuery, FontAwesome, and integrates Google Analytics and Tag Manager for analytics. The site is mobile-optimized with good navigation and SEO practices. The CMS appears custom-built, with administrative access links present. Performance is moderate, with asynchronous loading of scripts enhancing user experience. From a security perspective, the site uses HTTPS and secure form submissions via Mailchimp. However, it lacks explicit HTTP security headers and does not publish a security policy or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the HTML content. Privacy and cookie policies are comprehensive and GDPR compliant, reflecting a mature privacy posture. Overall, the website is trustworthy and professionally maintained, though the absence of WHOIS registrant data reduces transparency. The site is safe for general audiences with no adult or explicit content. Strategic improvements in security headers and incident response disclosures would enhance the security posture and trustworthiness further.

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. 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 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. 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

NSU is a well-established labor union focused on the maritime sector in Norway, providing advocacy, health and wellbeing support, and legal assistance to seafarers. Its business model is non-profit, relying on membership and union activities. The union maintains partnerships with international organizations such as ITF Seafarers and LabourStart, enhancing its influence and support network. The website content and structure indicate active engagement with members through news, events, and educational seminars. The union targets maritime workers globally but with a Norwegian base. Growth indicators include regular news updates and event scheduling. The partnership ecosystem is strong, linking to reputable maritime and labor organizations.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and no sensitive data leaks are evident. Use of third-party services like Mailchimp and Google Analytics is handled securely with asynchronous script loading. However, the absence of key HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options is a gap. No vulnerability disclosure or incident response information is published, which limits transparency and readiness perception. GDPR compliance is well addressed through privacy and cookie policies with explicit consent mechanisms. Overall, the security posture is adequate for the business type but could be improved with additional security controls and transparency.

Recommendations

  1. Implement and enforce HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  2. Publish a security policy and incident response contact information to improve transparency and preparedness.
  3. Regularly audit and update third-party scripts and dependencies to mitigate potential vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Consider obtaining and displaying relevant certifications or trust badges to strengthen business credibility.

Technical notes

Notes

The website is built on a custom CMS platform with modern front-end technologies such as Bootstrap 4.3.1, jQuery 3.4.1, and FontAwesome 5.15.4. It integrates Google Analytics and Google Tag Manager for user tracking and Mailchimp for newsletter subscriptions. The site is mobile responsive and SEO optimized with proper meta tags and Open Graph data. Performance is moderate, with asynchronous loading of analytics scripts improving load times. The presence of a CMS admin link suggests backend management capabilities. There is no explicit hosting provider information. The site could benefit from enhanced accessibility and security header implementation to reduce technical risks.
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.
