  3. (c) Business continuity, backups and crisis management: Not visible from outside
  4. (d) Supply chain security: Not visible from outside

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. GDPR outside view

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

    • 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

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

  • Security headers: did not complete in this scan.
  • Email security: did not complete in this scan.
  • DNS health: did not complete in this scan.
  • 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

ZEISS i Danmark operates as a key regional subsidiary of the ZEISS Group, serving the Nordic market with specialized optical and technological solutions. The business model focuses on manufacturing and delivering high-precision products and services across multiple sectors including healthcare, industrial measurement, and digital innovation. The company benefits from a strong brand reputation, extensive product portfolio, and a well-established global and regional network. The website indicates a focus on expert customer support and localized service, enhancing customer trust and engagement. The presence of multiple language and regional sites suggests a strategic approach to market segmentation and localization. The company’s market position as a technology leader is reinforced by its long history and innovation-driven portfolio.

Security posture

The website demonstrates a solid security posture with HTTPS enabled and multiple security headers implemented, including HSTS, CSP, and X-Frame-Options. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Forms appear to be secured, and no signs of common web vulnerabilities are evident. However, the absence of publicly accessible incident response or vulnerability disclosure pages limits transparency in security incident handling. Privacy policies and cookie consent mechanisms are in place, supporting compliance with GDPR. Overall, the security maturity is good but could be enhanced by publishing explicit security policies and contact channels for security incidents.

Recommendations

  1. Publish a dedicated vulnerability disclosure and incident response policy page to improve transparency and trust.
  2. Add explicit security contact channels such as security@ or abuse@ email addresses.
  3. Enhance visibility of data retention policies and user privacy controls.
  4. Consider adding security certifications or compliance badges on the website.
  5. Regularly review and update third-party scripts and tracking tools to minimize privacy risks.

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.
