OSA, z.s. · Media · Czech Republic
Medium risk. 4 critical or high findings in GDPR outside view and Network security.
OSA, z.s. is a well-established collective rights management organization based in the Czech Republic, specializing in representing authors and publishers in the music industry. The organization provides licensing services for music users and supports the protection and promotion of music creators' rights. With over 100 years of experience, OSA holds a significant market position in the Czech Republic and maintains an active presence on multiple social media platforms. The website is professionally designed, content-rich, and targets authors, publishers, and music users effectively. Technically, the website employs modern JavaScript libraries such as jQuery and Swiper.js, integrates Google Tag Manager and Google Analytics for tracking, and uses the Nette Framework for backend form handling. The site is mobile-optimized and demonstrates good SEO practices. However, some security headers are missing, and no explicit security policy or incident response information is published, which could be improved. From a security perspective, the site uses HTTPS and implements cookie consent mechanisms compliant with GDPR. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of WHOIS data reduces domain registration trustworthiness, but the website's professional content and business information support its legitimacy. Overall, OSA's website presents a strong digital presence with good privacy compliance and business credibility. Strategic improvements in security headers, incident response transparency, and WHOIS data verification would enhance trust and security posture further.
Scanned
NIS2 Art. 21(2)
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.

Each check with its score, findings and the evidence it collected.

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.
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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
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.
