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

Duell operates in a competitive POS market with a focus on industry-specific solutions and seamless integrations with leading accounting platforms like Tripletex, Visma, and Fiken. Its business model centers on B2B software and hardware sales, targeting medium-sized enterprises across multiple sectors. The company leverages partnerships with software providers and payment processors such as Loomis to enhance its offerings. The website content and integrations reflect a strategic approach to capturing diverse market segments, emphasizing ease of use and comprehensive functionality. Growth potential is supported by continuous product development, including the upcoming DUELL v4 system.

Security posture

The website employs HTTPS and uses Google Analytics for tracking, with no evident exposure of sensitive data or vulnerable libraries. However, the lack of security headers and absence of documented security policies or incident response plans indicate gaps in security maturity. No vulnerability disclosure or security.txt files were found, limiting transparency for security researchers. The site would benefit from implementing standard security headers, formalizing privacy and cookie policies, and providing clear contact channels for security incidents. These improvements would enhance trust and compliance with GDPR and other regulations.

Recommendations

  1. Implement comprehensive privacy and cookie policies with user consent mechanisms to improve GDPR compliance.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to strengthen security posture.
  3. Publish a security.txt file and vulnerability disclosure policy to facilitate responsible reporting of security issues.
  4. Include explicit contact information including company emails and phone numbers to improve business credibility and user trust.
  5. Regularly audit and update third-party plugins and scripts to mitigate risks from vulnerable components.

Technical notes

Notes

The website is built on WordPress 6.8.3 using the Elementor page builder, supported by various plugins including Heroic Knowledge Base, Metform, BDThemes Element Pack, and UICore Elements. It uses modern web technologies such as SVG icons, CSS variables, and asynchronous JavaScript loading for analytics. Performance is moderate with good mobile optimization and basic accessibility features. SEO is supported by proper meta tags and structured navigation. Hosting provider details are not explicitly identified. The technical stack is modern but could benefit from enhanced security configurations 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.
