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.

Technical appendix

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

Business context

Business profile

ZEISS holds a strong market position as a global leader in optics and related technologies. Its diversified business model covers multiple high-tech sectors, targeting both B2B and B2C customers. The Italian operations focus on commercializing and supporting products across biomedical, industrial, and consumer optics sectors. The presence of ISO certifications and detailed business division descriptions enhance credibility. The website's multilingual and regional structure supports a broad international audience. The company leverages partnerships and subsidiaries to maintain a strong local presence.

Security posture

The website demonstrates a solid security posture with HTTPS enforced, comprehensive security headers, and no visible exposure of sensitive data. However, it lacks explicit privacy and cookie policies, incident response information, and vulnerability disclosure mechanisms, which are important for compliance and transparency. The use of Google Tag Manager indicates moderate user tracking. Overall, the security maturity is good but could be improved by publishing detailed policies and contact points for security incidents.

Recommendations

  1. Publish a clear and comprehensive privacy policy including GDPR compliance details.
  2. Implement a cookie consent banner or mechanism to comply with EU regulations.
  3. Add a dedicated security policy page and incident response contact information.
  4. Introduce a vulnerability disclosure policy and security.txt file to enhance transparency.
  5. Provide direct company contact emails and phone numbers for customer and security inquiries.

Technical notes

Notes

The website is built on Adobe Experience Manager, a robust enterprise CMS, and uses modern frontend technologies including SVG icons, lazy loading images, and responsive design. Google Tag Manager is used for analytics and event tracking. The site is well-structured with proper meta tags, Open Graph data, and JSON-LD structured data for SEO. Performance is moderate with room for optimization. Accessibility features such as skip links and semantic HTML are present, contributing to a good user experience. No critical technical debt or vulnerabilities were detected in the analyzed 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.
