Jak na Internet is an educational initiative operated by CZ.NIC, the Czech national domain registry. The website provides a comprehensive series of short educational videos and accompanying texts aimed at increasing public awareness and understanding of the Internet and its various aspects. The project targets a broad audience including educators and general users interested in Internet literacy. The site is well-structured with categorized content covering topics from Internet safety to technical explanations and social aspects. Technically, the site uses standard web technologies including jQuery and embeds YouTube videos securely with sandboxing. Analytics are handled via Piwik with cookies disabled, reflecting a privacy-conscious approach. However, explicit privacy policies and terms of service are not present, and no direct contact information is provided on the site. The domain WHOIS data is not publicly available, consistent with CZ.NIC's registry policies, but the domain's legitimacy is strongly supported by its association with CZ.NIC. Security headers and advanced security configurations are not detected, suggesting room for improvement in security posture.

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.
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.

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

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.

Leaked records that mention jaknainternet.cz, from OffSeq Breach.
No leaked records found
Breach holds no records for jaknainternet.cz right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Business context
Business profile
The website serves as a public awareness and educational platform under the CZ.NIC umbrella, positioning itself as a trusted source for Internet education in the Czech Republic. Its business model is non-commercial, focusing on education and public service. The project benefits from strong brand association with CZ.NIC, enhancing trust and credibility. The content is designed for a general audience including teachers, students, and Internet users seeking knowledge about Internet technologies and safety. The site links to several related CZ.NIC services and partner sites, indicating a well-integrated ecosystem. Growth potential lies in expanding educational outreach and possibly integrating more interactive or updated content. The absence of direct contact details and formal policies may limit user engagement and trust to some extent.
Security posture
The security posture of the website is moderate. The site uses HTTPS and embeds third-party content with sandboxing, which are positive practices. However, the absence of HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces protection against common web attacks. No explicit security or incident response policies are published, and no security.txt or vulnerability disclosure information is available. The cookie consent mechanism is implemented, but privacy policy details are missing. The use of Piwik analytics with cookies disabled indicates some privacy awareness. Overall, the site would benefit from enhanced security headers, clear privacy and security policies, and published incident response contacts to improve trust and compliance.
Recommendations
Implement comprehensive HTTP security headers including CSP, HSTS, and X-Frame-Options to mitigate common web vulnerabilities.
Publish a clear and accessible privacy policy and terms of service to improve transparency and GDPR compliance.
Provide explicit contact information for general inquiries and security incident reporting to enhance trust and responsiveness.
Regularly audit and update third-party scripts and embedded content to minimize security risks.
Consider adding a security.txt file and a vulnerability disclosure policy to encourage responsible reporting of security issues.

Technical notes
Notes
The website is built using classic web technologies including jQuery and jQuery UI, with embedded YouTube videos and Piwik analytics for tracking. The site is structured with clear navigation and categorized content, supporting good user experience. Mobile optimization is basic but functional. No modern CMS or advanced frameworks are detected. Performance is moderate with no obvious issues but could be improved with modern optimization techniques. Accessibility features are minimal but present. The hosting provider and SSL configuration details are not explicitly available from the content. Overall, the technical infrastructure is stable but could benefit from modernization and enhanced security configurations.
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.
