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

Seacontractors is a globally active maritime service provider specializing in anchor handling tugs and multi-purpose vessels with a focus on shallow draft operations. They serve key industries such as oil & gas, renewables, salvage, and maritime infrastructure, positioning themselves as a leading operator worldwide. The website demonstrates a professional digital presence with detailed vessel information, active social media links, and 24/7 contact availability. Technically, the site uses modern frameworks like Bootstrap and jQuery, integrates Google Analytics and Tag Manager for tracking, and employs Google reCAPTCHA v3 for form security. However, the absence of WHOIS registration data raises concerns about domain legitimacy. Security posture is moderate with HTTPS usage and form protections but lacks visible security headers and explicit privacy/cookie policies. Overall, the site is functional and professional but would benefit from enhanced transparency and security practices.

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

7 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 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

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 maritime energy and transportation sectors, offering specialized vessel services globally. Their fleet and project experience across 95 countries indicate a medium-sized enterprise with a strong market position. The business model focuses on service delivery with a fleet of over 25 vessels, targeting offshore construction, towage, salvage, and renewable energy projects. The website content and social media presence support a credible brand image. However, the missing WHOIS data is a notable anomaly that could impact trust. There is no evidence of parent or subsidiary companies. The company emphasizes 24/7 availability and detailed technical specifications, suggesting a customer-centric approach and operational transparency.

Security posture

The website employs HTTPS and Google reCAPTCHA v3, indicating baseline security awareness. However, the lack of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces defense-in-depth. No published security policies or incident response contacts were found, limiting transparency on security governance. The absence of cookie consent mechanisms and detailed privacy compliance disclosures suggests partial GDPR compliance. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is moderate but could be significantly improved by implementing recommended headers, policies, and transparency measures.

Recommendations

  1. Register and verify domain WHOIS information to improve legitimacy and trust.
  2. Implement and publish a comprehensive cookie policy with user consent mechanisms.
  3. Add security headers including CSP, HSTS, and X-Frame-Options to enhance protection.
  4. Publish a security policy and incident response contact information on the website.
  5. Consider adding a vulnerability disclosure policy and security.txt file for transparency.

Technical notes

Notes

The website is built on a modern tech stack including Bootstrap 4.6.1 and jQuery 3.6.0, with additional libraries like Swiper.js and FancyBox for UI components. Google Tag Manager and Analytics are used for tracking, and Google reCAPTCHA v3 protects forms against bots. The site appears mobile responsive and well-structured with clear navigation. Performance is moderate with no major issues detected. The CMS appears to be MODX based on URL patterns and template structure. Accessibility features are basic and could be enhanced. SEO is supported by proper meta tags and structured content. Overall, the technical implementation is solid but could benefit from improved security headers and privacy compliance features.
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.
