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

Seiler Medical is a well-established company specializing in high-quality medical optical instruments such as surgical dental microscopes, colposcopes, ENT devices, and related accessories. With over 80 years of industry presence, the company targets medical professionals requiring precision optics and offers a comprehensive product line alongside services like repair, training, and demos. The website reflects a mature digital presence built on WordPress with modern technologies and SEO optimizations, providing a professional user experience with rich multimedia content and clear navigation. Security posture is generally good with HTTPS and form protections, though some security headers could be improved. Privacy and cookie policies are present and GDPR compliant, enhancing trust. However, the absence of WHOIS domain registration data raises concerns about domain legitimacy, which should be further investigated to ensure full trustworthiness.

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

5 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  3. 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

    • 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

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

Seiler Medical operates in the healthcare sector, focusing on manufacturing and selling precision optical medical devices. The company leverages its long history and ISO certification as trust signals and maintains a strong brand presence with customer testimonials and a comprehensive product catalog. The business model includes direct sales, service, and training, targeting specialized medical practitioners. Partnerships with related corporate sites indicate a broader corporate structure. The website's content quality and branding consistency support a medium-sized enterprise profile with a solid market position in medical optics.

Security posture

The website employs HTTPS and integrates Google reCAPTCHA for form security, indicating a baseline security awareness. However, the lack of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests room for improvement. No vulnerabilities or exposed sensitive data were detected in the analysis. Privacy compliance is well addressed with visible policies and consent mechanisms. The missing WHOIS data is a critical concern from a trust perspective but does not directly indicate a technical security flaw. Overall, the security posture is moderate with recommendations to enhance HTTP headers and conduct regular security audits.

Recommendations

  1. Verify and update domain WHOIS registration to ensure transparency and trust.
  2. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Maintain regular updates of WordPress core, themes, and plugins to mitigate vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Continue monitoring privacy compliance and update policies as regulations evolve.

Technical notes

Notes

The website is built on WordPress using the Divi theme and several plugins including Gravity Forms for data collection and Google Tag Manager for analytics. It uses modern web fonts via Typekit and multimedia support with MediaElement.js. Performance is moderate with good mobile optimization and SEO practices. Accessibility is basic and could be improved. The technical stack is standard for a professional business website, but hosting provider details are not disclosed. The site uses HTTPS with a good SSL configuration but lacks some advanced security headers. Overall, the technical infrastructure supports a professional and functional online presence with opportunities for security and accessibility 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.
