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

3 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. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

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

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

AESSEAL DANMARK A/S holds a strong market position as a leading specialist in mechanical seals, leveraging its parent company's global footprint. The business model is B2B, targeting industrial sectors requiring fluid handling and sealing solutions. The company emphasizes customer service, quality, and delivery reliability, supported by a small but skilled team. Partnerships with Garlock and Belzona expand its product portfolio. The website's content and structure support its business goals, providing clear product information and contact channels. The domain age and registration details align well with the company's history, reinforcing credibility. The company could enhance its competitive edge by publishing security policies and incident response contacts to build further trust.

Security posture

The website demonstrates a good security baseline with HTTPS enforced and a cookie consent banner that complies with GDPR requirements. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. There is no visible security policy or incident response information, which could be a gap in transparency and readiness. The use of third-party scripts like Google Tag Manager and Iubenda is managed with consent mechanisms, supporting privacy compliance. Overall, the security posture is adequate but could be strengthened with additional technical controls and published policies.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to mitigate common web attacks.
  3. Publish a dedicated security policy and incident response contact information on the website.
  4. Add a security.txt file to facilitate responsible vulnerability disclosure.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are used.

Technical notes

Notes

The website is built on Drupal 10, a modern and secure CMS platform, indicating good technical infrastructure. It uses Iubenda for cookie consent management and Google Tag Manager for analytics, showing compliance with privacy regulations and data-driven marketing. The site is mobile optimized and accessible, with good SEO practices including canonical links and meta tags. Performance is moderate, with no major issues detected. The absence of DNSSEC and security headers suggests some technical debt in security hardening. Hosting provider details are not explicit, but the domain registrar is Safenames Ltd. Overall, the technical setup supports the business needs well but can benefit from enhanced security configurations.
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.
