The company targets global maritime and coastal infrastructure markets, offering innovative solutions to complex infrastructural challenges.

The site is mobile optimized and accessible with good SEO practices. Security posture is solid with HTTPS enforced, CSRF protection in forms, and bot mitigation via Google reCAPTCHA, though some security headers are not explicitly detected.

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

1 finding 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.

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

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

Boskalis operates as an essential entity in the maritime infrastructure and energy sectors, with a business model focused on providing dredging and offshore services globally. The company benefits from a strong market position as a leader in its industry, supported by a long-established domain and consistent corporate identity. The website's navigation and content structure support clear communication of services and corporate governance. The use of privacy-respecting analytics and consent management tools indicates a mature approach to data privacy. However, the absence of explicit contact emails and phone numbers on the homepage suggests a preference for controlled communication channels, possibly via subscription forms or internal contact pages. The company appears to maintain a professional digital presence with opportunities to enhance transparency through published security policies and incident response information.

Security posture

The website demonstrates a good security posture with mandatory HTTPS, CSRF tokens in forms, and Google reCAPTCHA integration to prevent automated abuse. Cookie consent is managed via Cookiebot, ensuring compliance with GDPR and other privacy regulations. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a gap that could be addressed to harden security further. No vulnerabilities or exposed sensitive data were detected in the analysis. The lack of a published security policy or incident response contact limits transparency and readiness perception. Overall, the security maturity is solid but could be improved by publishing security documentation and implementing additional HTTP security headers.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and verify HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a dedicated security policy and incident response contact information on the website.
  4. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Enhance contact information visibility by providing verified company emails and phone numbers for customer and security inquiries.

Technical notes

Notes

The website is built using modern JavaScript technologies and integrates third-party services such as Matomo for analytics and Cookiebot for consent management. Hosting is via Azure DNS, indicating enterprise-grade infrastructure. The site is mobile optimized and accessible, with good SEO metadata and Open Graph tags for social sharing. Performance is moderate, with asynchronous loading of scripts like reCAPTCHA and analytics. The use of CSRF tokens in forms and reCAPTCHA indicates attention to security in user input handling. There is no detected CMS or framework explicitly identified, suggesting a custom or proprietary platform. Technical risks are minimal but include the absence of DNSSEC and some security headers, which are recommended for further hardening.
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.
