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

Adam Trnka's website serves as a personal portfolio showcasing his expertise as a technology enthusiast, product manager, consultant, creative professional, and cameraman. The site highlights his experience in digitalizing business needs, video production, and technology development. The business model is service-oriented, targeting clients seeking IT consulting, product management, and multimedia services. The website is well-branded with consistent design and clear contact information, supporting a moderate level of business credibility. Technically, the site uses a modern frontend stack including Bootstrap, jQuery, and Google Fonts, ensuring good mobile responsiveness and user experience. However, no CMS or hosting provider information is discernible. Performance is moderate with no advanced analytics or tracking scripts detected, indicating a privacy-conscious approach but also limited marketing insights. From a security perspective, the site lacks visible security headers and privacy/cookie policies, which lowers its compliance posture. The absence of WHOIS data reduces transparency but is likely due to privacy protection, which is reasonable for a personal brand. No forms or sensitive data collection points reduce attack surface, but improvements in SSL configuration and security headers are recommended. Overall, the website is safe, professional, and suitable for general audiences. The main risks relate to privacy compliance and security best practices, which can be addressed to enhance trust and regulatory adherence.

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

7 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 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

Adam Trnka operates as an individual consultant and creative professional in the technology sector, focusing on IT business consulting, product management, and video production. The website positions him as a small-scale service provider with a personal brand rather than a corporate entity. The target market includes businesses and individuals seeking digital transformation and multimedia services. The lack of extensive marketing tools or analytics suggests a focus on direct client relationships rather than broad digital marketing. Partnerships with domains like orine.one and video.trnka.one indicate a small ecosystem of related services. The business model relies on personal expertise and direct communication, supported by clear contact details and professional presentation.

Security posture

The website demonstrates a basic security posture with HTTPS likely enabled (though SSL configuration details are unknown), no forms or sensitive data collection, and no exposed vulnerabilities in the HTML content. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a notable gap. No privacy or cookie policies are present, which impacts GDPR compliance. The lack of incident response or vulnerability disclosure information suggests limited formal security processes. Overall, the security maturity is low to moderate, suitable for a personal portfolio but requiring enhancements for higher trust and compliance.

Recommendations

  1. Implement and enforce HTTPS with a strong SSL/TLS configuration and regularly monitor certificate validity.
  2. Add essential security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  3. Publish clear privacy and cookie policies to enhance GDPR compliance and user trust.
  4. Consider adding a vulnerability disclosure policy or security.txt file to demonstrate security transparency and readiness.
  5. Enhance website analytics and marketing tools cautiously to balance business growth with privacy compliance.

Technical notes

Notes

The website is built using a modern frontend stack with Bootstrap 4, jQuery 3.4.1, Popper.js, Font Awesome, and Google Fonts, ensuring responsive design and good user experience. No CMS or backend technologies are detectable from the HTML content. The site loads external assets from a CDN subdomain (cdn-images.trnka.one) and uses minimal JavaScript plugins. Performance is moderate with no heavy scripts or trackers. Accessibility is basic but could be improved with ARIA attributes and semantic HTML enhancements. SEO is supported by proper meta tags including keywords and description. The absence of analytics or tracking scripts indicates minimal data collection. Hosting provider and server details are not available from the provided data.
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.
