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

4 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

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

Allseas operates in the offshore energy and transportation sectors, delivering specialized engineering and construction services. Their market position is strong, supported by a large project portfolio and advanced vessel capabilities. The business model centers on contracting for subsea and offshore infrastructure projects, targeting energy companies and industrial clients. The website's content and navigation indicate a focus on professional stakeholders and potential employees. Tracking and marketing tools suggest active digital engagement strategies. Lack of visible direct contact info and WHOIS transparency are minor concerns but do not detract significantly from overall credibility.

Security posture

The website enforces HTTPS and integrates standard tracking pixels without exposing sensitive data. However, it lacks visible security headers and explicit security or incident response policies. No vulnerability disclosure or security.txt files are present, which could improve transparency and trust. The absence of cookie consent mechanisms despite tracking scripts indicates a GDPR compliance gap. Overall, the security maturity is moderate to good but could benefit from enhanced policy publication and technical header implementation.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy and X-Frame-Options.
  2. Add a clear cookie consent banner to comply with GDPR and inform users about tracking.
  3. Publish a dedicated security policy and incident response contact information.
  4. Consider adding a vulnerability disclosure policy or security.txt file for transparency.
  5. Enhance contact information visibility to improve user trust and business credibility.

Notes

The website uses Drupal 10 CMS with modern JavaScript libraries including Modernizr and integrates Google Tag Manager, Facebook Pixel, and LinkedIn Insight for analytics and marketing.

Hosting provider details are not disclosed. The site structure is clear with well-organized navigation and content blocks.
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.
