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

Gigahertz-Optik is a German technology company specializing in high precision optical radiation and light measurement products spanning the UV to IR spectrum. The company positions itself as a world-renowned expert in this niche, targeting scientific, industrial, and research clients requiring accurate light measurement solutions. The website reflects a professional B2B business model focused on manufacturing and sales of precision instruments. Technically, the website employs modern web technologies including Google Tag Manager and Cookiebot for analytics and cookie consent, with a responsive design and good SEO practices. However, it lacks explicit privacy and terms of service pages, and no direct contact information was found in the analyzed content. Security posture is moderate with cookie consent implemented but missing security headers and formal security policies. Overall, the site is accessible with no WAF or blocking mechanisms detected, and content is safe for general audiences.

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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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

The company operates in the specialized technology sector of optical measurement, leveraging German engineering reputation and innovation. Its market position is strong within its niche, supported by claims of world-renowned expertise. The business model is focused on product sales to technical and industrial customers. The website content and branding are consistent and professional, supporting credibility. The absence of explicit contact details and privacy policies suggests room for improvement in transparency and compliance. No partner or subsidiary domains were identified, indicating a focused standalone operation. The use of Google Tag Manager and Cookiebot indicates awareness of digital marketing and privacy compliance, albeit incomplete.

Security posture

The website demonstrates a basic security posture with HTTPS implied but no explicit security headers detected in the provided data. Cookie consent is implemented via Cookiebot, indicating some privacy compliance effort. However, the lack of privacy policy, terms of service, security policy, incident response contacts, and vulnerability disclosure mechanisms reveals gaps in compliance and security maturity. No exposed vulnerabilities or suspicious domains were found. The absence of security.txt or abuse contacts limits incident response readiness. Overall, the security posture is moderate but could be significantly improved by adding formal policies and enhancing technical security controls.

Recommendations

  1. Publish a comprehensive privacy policy page to improve GDPR compliance and user trust.
  2. Add a terms of service page to clarify user and business obligations.
  3. Implement and publish a security policy and incident response contact information.
  4. Configure and deploy security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Create a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.

Technical notes

Notes

The website uses modern front-end technologies including CSS Grid and Flexbox for layout, and loads fonts asynchronously for performance. Google Tag Manager is used for analytics, and Cookiebot manages cookie consent, indicating a moderate level of digital maturity. The site appears mobile optimized with responsive design. However, no CMS or hosting provider information was detected. Performance is moderate with preloading of fonts and asynchronous scripts. Accessibility is basic, with room for improvement in semantic markup and ARIA attributes. SEO is good with proper meta tags and canonical URLs. Technical risks include missing security headers and incomplete privacy compliance documentation.
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.
