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

Tiny is a Czech non-profit educational AI application developed by AI dětem, z.s., designed to assist teachers with formative assessment and provide personalized mentoring to children. The platform offers individualized feedback and tailored educational content, primarily targeting primary and secondary school students and educators. Supported by academic institutions such as ČVUT and Univerzita Karlova, and funded in part by Google.org Impact Challenge, Tiny positions itself as an innovative AI-driven educational tool in the Czech and Slovak markets. The business model focuses on pilot school partnerships and content collaboration to expand its offerings. Technically, Tiny is built on a modern WordPress CMS with Elementor and integrates various JavaScript libraries and Google Analytics for tracking. The website is well-structured, mobile-optimized, and SEO-friendly, reflecting a mature digital presence. However, some security best practices such as security headers and cookie consent mechanisms are missing, which could be improved to enhance user trust and compliance. From a security perspective, the site uses HTTPS and does not expose sensitive data or vulnerable libraries. The lack of visible security policies and incident response information suggests room for improvement in transparency and readiness. WHOIS data is unavailable due to TLD registry restrictions, but the website content and affiliations indicate legitimacy and trustworthiness. Overall, Tiny demonstrates a strong educational mission with solid technical implementation and good business credibility. Strategic enhancements in security policies, privacy compliance, and incident response transparency would further strengthen its position and user confidence.

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

11 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 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';…

  3. 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

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

Tiny operates in the education technology sector as a non-profit initiative focused on AI-assisted learning. Its competitive advantage lies in personalized AI mentoring and formative assessment tools tailored for children and educators. Revenue streams are likely grant-based and partnership-driven rather than commercial sales. The target customers are schools and teachers in Czechia and Slovakia, with growth potential through expanding content partnerships and wider school adoption. The project benefits from a strong partnership ecosystem including academic institutions and Google.org funding. Strategic observations include the importance of expanding content offerings, enhancing user engagement through interactive features, and improving compliance and security transparency to build trust.

Security posture

The current security maturity level is moderate. HTTPS is enforced, and no critical vulnerabilities or exposed sensitive data were detected. However, the absence of security headers such as Content-Security-Policy and lack of a cookie consent mechanism indicate compliance gaps. There is no visible incident response or vulnerability disclosure information, which could hinder rapid response to security incidents. GDPR compliance is partially addressed via external privacy policy linkage but could be improved with on-site policies and consent management. The security culture appears nascent, with room to formalize policies and enhance transparency. Business impact of these gaps is moderate, primarily affecting user trust and regulatory compliance.

Recommendations

  1. Implement comprehensive security headers (CSP, X-Frame-Options, X-Content-Type-Options) to mitigate common web attacks.
  2. Deploy a cookie consent banner/mechanism to comply with GDPR and enhance user privacy transparency.
  3. Publish clear security and privacy policies directly on the website, including incident response and data protection details.
  4. Establish a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  5. Enhance accessibility features to improve inclusivity and compliance with standards.

Technical notes

Notes

The website uses a modern WordPress CMS with Elementor page builder and integrates several JavaScript libraries including jQuery and DotLottie for animations. Google Analytics and Google Tag Manager are used for traffic monitoring. The site is mobile-optimized and SEO-friendly with proper meta tags and Open Graph data. Performance is moderate, with lazy loading and animation optimizations. Technical debt appears low, but security best practices could be improved. Hosting provider details are not explicitly identified. Overall, the technical infrastructure supports the business goals effectively but would benefit from enhanced security and privacy features.
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.
