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

Espersen is a medium-sized Danish company specializing in sustainable seafood production, emphasizing responsible sourcing, quality, and social responsibility. Their website highlights their commitment to environmental sustainability, worker welfare, and product innovation. The company targets seafood industry professionals, environmentally conscious consumers, and potential employees. Technically, the website is built on Dynamicweb 8 CMS, uses Bootstrap and jQuery libraries, and features a responsive design with moderate performance. Security posture is generally good with HTTPS enforced and no visible sensitive data exposure, but lacks advanced security headers and explicit privacy compliance mechanisms. The absence of WHOIS registration data reduces trustworthiness and suggests a need for further verification. Overall, the website is professional and trustworthy but could improve privacy transparency and security hardening.

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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

Espersen holds a solid position in the sustainable seafood manufacturing sector with a clear focus on environmental and social governance. Their business model revolves around producing and distributing a variety of seafood products with an emphasis on sustainability and quality. The company maintains partnerships with related seafood brands such as Rahbek Fisk and collaborates with external solution providers like Smartpage A/S. The website content and structure indicate a mature business with international reach, offering career opportunities and detailed sustainability reporting. However, the lack of public WHOIS data and limited direct contact details online may affect perceived transparency.

Security posture

The website enforces HTTPS and avoids exposing sensitive information in its HTML content. However, it lacks implementation of key security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security, which are recommended to mitigate common web attacks. No incident response or vulnerability disclosure information is provided, limiting transparency in security management. The absence of a privacy policy and cookie consent mechanism also indicates partial non-compliance with GDPR best practices. Overall, the security posture is moderate but could be significantly improved by adopting standard security headers, publishing privacy and security policies, and establishing clear incident response channels.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a clear and accessible privacy policy and enhance cookie consent mechanisms to ensure GDPR compliance.
  3. Establish and publicize incident response and vulnerability disclosure procedures to improve security transparency.
  4. Regularly audit and update third-party libraries and frameworks to mitigate potential vulnerabilities.
  5. Enhance accessibility features to meet recognized standards and improve user experience for all visitors.

Technical notes

Notes

The website uses a modern CMS (Dynamicweb 8) combined with Bootstrap and jQuery for frontend responsiveness and interactivity. The RoyalSlider plugin is used for image sliders. The site is mobile optimized with responsive design and includes SEO-friendly meta tags and canonical URLs. Performance is moderate with some inline styles and external CSS/JS dependencies. No analytics or tracking scripts were detected in the provided HTML, indicating minimal user tracking. The site lacks advanced accessibility features and security headers, which are areas for technical improvement. Hosting provider details are not discernible from the HTML content.
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.
