Risk levelMedium

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

The website www.100letosa.cz serves as a commemorative platform celebrating 100 years of the Ochranný svaz autorský (OSA), the Czech collective rights management organization for music authors. It provides a rich historical timeline and educational content about the evolution of copyright and the Czech music industry. The site targets Czech-speaking audiences interested in cultural heritage and music history. Technically, the site uses standard web technologies such as Bootstrap, jQuery, and AOS for animations, delivering a visually appealing and navigable experience, though mobile optimization and accessibility are basic. Security posture is limited, with no detected security headers or privacy policies, and WHOIS data for the domain is unavailable, which reduces transparency and trust in domain registration details. Overall, the site is professional and trustworthy in content but would benefit from enhanced security and privacy compliance measures.

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

9 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  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"

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

OSA is a well-established non-profit organization focused on protecting music authors' rights in the Czech Republic. The website reflects its role as a cultural and historical authority in the music industry. The business model revolves around collective rights management and advocacy. The site positions OSA as a key player in the Czech media sector with a medium-sized organizational footprint. The absence of direct contact information or commercial elements suggests the site is primarily informational and educational. The partnership with the official OSA domain strengthens credibility. Growth opportunities include expanding digital presence and improving user engagement through enhanced interactivity and compliance transparency.

Security posture

The website currently exhibits a basic security posture. It uses HTTPS (assumed from modern standards, though SSL details are unknown), but lacks important security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security. No forms or input fields are present, reducing attack surface, but also limiting user interaction. The absence of privacy and cookie policies indicates non-compliance with GDPR best practices. No incident response or security contact information is provided. The missing WHOIS data further complicates trust evaluation. Overall, the site is low risk but would benefit from implementing standard security headers, privacy notices, and transparent domain registration information.

Recommendations

  1. Implement comprehensive privacy and cookie policies to ensure GDPR compliance and user trust.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  3. Ensure domain WHOIS information is publicly available or provide justification for privacy protection to improve transparency.
  4. Improve mobile responsiveness and accessibility features to broaden audience reach and comply with accessibility standards.
  5. Provide clear contact information and incident response channels to facilitate communication and security reporting.

Technical notes

Notes

The website is built using Bootstrap for responsive layout, jQuery and Popper.js for interactivity, and AOS for scroll animations. It loads fonts from Google Fonts and assets locally. The site structure is clear with a vertical navigation menu and well-organized content sections. No CMS or hosting provider information is detectable. Performance is moderate with no heavy scripts or trackers. SEO is basic with meta description and title tags but lacks Open Graph or JSON-LD structured data. Accessibility is basic with no ARIA landmarks or roles detected. The site does not use analytics or tracking scripts, which limits data-driven insights but enhances privacy.
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.
