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 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

The company operates in the transportation sector, focusing on maritime safety and operational support. Their business model is B2B, providing technical documentation and digital tools to a niche market of yacht builders and maritime professionals. The website indicates a medium-sized organization with a team of nearly 50 technical authors. The presence of partner domains suggests collaboration with creative content providers. The company leverages digital marketing tools like Google Tag Manager and push notifications to engage users. However, the lack of visible contact information and WHOIS data may limit direct customer engagement and trust signals.

Security posture

The website enforces HTTPS and implements a GDPR-compliant cookie consent banner, indicating attention to privacy and security regulations. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces the overall security posture. No vulnerabilities or exposed sensitive data were detected in the content. The lack of published security policies or incident response contacts suggests room for maturity in security governance. The missing WHOIS data is a notable risk factor, potentially indicating domain registration issues or privacy protection that is not justified by the business type.

Recommendations

  1. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  2. Publish a security policy and incident response contact information to improve transparency and readiness.
  3. Verify and update WHOIS domain registration information to ensure legitimacy and trust.
  4. Enhance contact information visibility on the website to improve business credibility and customer trust.
  5. Regularly audit third-party scripts and plugins for vulnerabilities and compliance with privacy regulations.

Technical notes

Notes

The website uses WordPress CMS with Gutenberg blocks, jQuery, Google Tag Manager, and WonderPush for push notifications. The site is mobile optimized with good accessibility and SEO practices. Performance is moderate, with room for improvement in loading speed and technical optimization. The cookie consent plugin is well integrated, supporting GDPR compliance. Hosting provider details are not evident from the content. The site lacks advanced security headers and a security.txt file, which are recommended for modern web applications. Overall, the technical infrastructure supports the business needs but can be enhanced for security and performance.
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.
