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

Hamburgische Schiffbau-Versuchsanstalt GmbH (HSVA) is a well-established private and independent maritime service and consulting company based in Hamburg, Germany. Founded in 1913, HSVA specializes in maritime hydrodynamics, aerodynamics, and arctic technology, providing innovative solutions and world-class experimental testing facilities to clients worldwide. The company is recognized for its contributions to greener shipping and sustainable marine environments, holding a strong market position supported by national and international research collaborations. Technically, the HSVA website employs modern frontend technologies including Bootstrap and AOS for animations, alongside a robust cookie consent management system (ConsentFriend/Klaro!). The site is mobile-optimized with good SEO practices and moderate performance. While HTTPS is enforced, security headers are not explicitly detected, suggesting room for improvement in security hardening. From a security perspective, HSVA demonstrates a solid baseline with HTTPS and cookie consent mechanisms. However, the absence of explicit security policies, incident response contacts, and security.txt files indicates potential gaps in transparency and vulnerability management. No critical vulnerabilities or blocking mechanisms were detected, and the domain WHOIS data aligns well with the company’s identity and location, supporting legitimacy. Overall, HSVA presents a professional, trustworthy online presence with strong business credibility and compliance with privacy regulations. Strategic enhancements in security headers, incident response disclosures, and accessibility could further strengthen their security posture and user trust.

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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. 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';…

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

HSVA operates in the transportation and energy sectors, focusing on maritime hydrodynamics and related research services. Their competitive advantage lies in their long history, specialized expertise, and unique testing facilities including ice tanks and cavitation tunnels. The business model centers on consulting, experimental testing, numerical simulations, and software development for maritime clients globally. Revenue streams likely include service contracts, research partnerships, and specialized testing. The target customers are maritime industry stakeholders including shipbuilders, offshore operators, and research institutions. Growth indicators include active participation in international research and recent leadership updates. The company ecosystem includes a subsidiary (SDC) and active social media engagement, enhancing market presence and partnership opportunities.

Security posture

HSVA’s security maturity is moderate with foundational HTTPS implementation and cookie consent management. The lack of visible security headers and incident response information suggests areas for improvement in defense-in-depth and transparency. No exposed sensitive data or vulnerable libraries were detected in the provided content. GDPR compliance is evident through comprehensive privacy and cookie policies. Incident response readiness and vulnerability disclosure mechanisms are not publicly documented, which could impact rapid mitigation of security incidents. Overall, the security culture appears professional but could benefit from enhanced policy visibility and technical controls.

Recommendations

  1. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  2. Publish a dedicated security policy and incident response contact information to increase transparency and preparedness.
  3. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  4. Enhance accessibility features to meet higher compliance standards and improve user experience for all visitors.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern frontend stack with Bootstrap for responsive design and AOS for animations, ensuring good mobile optimization and user experience. ConsentFriend (Klaro!) is integrated for GDPR-compliant cookie management. The site loads JavaScript asynchronously and uses SVG graphics for visual elements. Performance is moderate, with no explicit CMS detected, suggesting a custom or static site architecture. SEO is supported by proper meta tags and Open Graph data. Hosting provider details are not disclosed. Technical risks include missing security headers and limited accessibility features, which could be addressed to reduce technical debt and improve compliance.
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.
