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 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
    • 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 do Brasil operates as a regional branch of the Carl Zeiss AG group, focusing on optics and optoelectronics. The company holds a strong market position internationally and offers key services in vision care, medical technology, and semiconductor manufacturing technology. The website supports multiple languages and regions, indicating a broad global footprint. The business model leverages advanced technology solutions and targets professional customers in healthcare and manufacturing sectors. The presence of a dedicated contact page and structured data enhances business credibility. The company benefits from a robust partnership ecosystem and a consistent brand identity across international domains.

Security posture

The website enforces HTTPS and uses Akamai CDN for hosting, which provides a secure and reliable infrastructure. Cookie consent is managed via OneTrust, indicating awareness of privacy regulations. However, no explicit security headers were detected in the provided data, and there is no published security policy or incident response contact information. The absence of a vulnerability disclosure or security.txt file suggests room for improvement in transparency and security maturity. No vulnerabilities or exposed sensitive data were found in the HTML content. Overall, the security posture is adequate for an enterprise site but could be enhanced by publishing security policies and implementing additional HTTP security headers.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the homepage.
  2. Implement and configure HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  3. Add a security policy page and provide incident response contact information to improve transparency.
  4. Create and publish a vulnerability disclosure or security.txt file to encourage responsible reporting.
  5. Conduct regular audits of third-party scripts and cookie consent configurations to ensure compliance and security.

Technical notes

Notes

The website uses Adobe Experience Manager CMS and is hosted on Akamai CDN, indicating a robust and scalable infrastructure. The tech stack includes modern JavaScript libraries, Google Tag Manager for analytics, and OneTrust for cookie consent management. The site is mobile optimized with responsive images and video content. SEO is supported by proper meta tags, Open Graph data, and JSON-LD structured data. Accessibility features are basic but present, such as skip links and ARIA labels. Performance is moderate, with some preloading of resources. There is no evidence of outdated or vulnerable libraries in the provided data. Overall, the technical implementation is solid but could benefit from enhanced accessibility and security header 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.
