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

ZEISS Austria is a regional branch of the global ZEISS Group, a leading technology company specializing in optics and optoelectronics. The website presents a professional corporate presence with detailed information about their business sectors including eye care, medical technology, industrial metrology, microscopy, photography, hunting optics, and digital solutions. The site is built on Adobe Experience Manager, indicating a mature digital infrastructure. The use of Google Tag Manager shows integration of modern analytics and marketing tools. Security posture is good with HTTPS and no obvious vulnerabilities, though explicit security headers could be improved. Privacy and cookie policies are not clearly found on the main page, which is a compliance gap.

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

4 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 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 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

  3. 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

  • 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.

Add-on

Leaked records that mention zeiss.at, from OffSeq Breach.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

ZEISS Austria operates as a medium-sized entity with about 125 employees and multiple locations. It serves diverse sectors such as automotive, biomedical research, and manufacturing with high precision optical and measurement technologies. The business model combines product manufacturing with sales, service, training, and demonstration. The company leverages its global brand and technology leadership to maintain a strong market position. The website links extensively to global ZEISS sites, indicating integration within a larger corporate ecosystem. No suspicious domains or partners were detected. The company targets professional and consumer markets with specialized products and solutions.

Security posture

The website enforces HTTPS and uses modern JavaScript modules and SVG icons, reducing risks of common web vulnerabilities. Google Tag Manager is used for analytics, which is standard but requires proper configuration to avoid privacy issues. No explicit security headers like Content-Security-Policy or X-Frame-Options were detected in the provided data, which could be improved to enhance security. No exposed sensitive data or vulnerable libraries were found. The absence of privacy and cookie policies on the main page is a compliance risk under GDPR. Incident response and security policy information are not publicly available, which could be improved for transparency.

Recommendations

  1. Publish clear and comprehensive privacy and cookie policies accessible from all pages.
  2. Implement and enforce Content-Security-Policy and X-Frame-Options HTTP headers.
  3. Provide explicit contact information for security incidents and data protection officer.
  4. Regularly audit third-party scripts and tracking tools for privacy compliance.
  5. Obtain and publish relevant security certifications and compliance attestations.

Technical notes

Notes

The website uses Adobe Experience Manager CMS, a robust enterprise platform suitable for complex corporate sites. The tech stack includes modern JavaScript with deferred and async loading, SVG icons for scalability, and responsive design for mobile optimization. Google Tag Manager is integrated for analytics and marketing. Performance is moderate with preloading of fonts and scripts. Accessibility features such as skip links and ARIA labels are present, indicating good usability practices. SEO is supported by meta tags, canonical links, and hreflang attributes for internationalization. No hosting provider details were found. Overall, the technical implementation is solid with room for security header enhancements.
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.
