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

MyCat.cz is a Czech-based company operated by HN Consulting Brno s.r.o., providing a specialized information system designed to simplify administrative tasks for language schools. The platform offers comprehensive management tools including course scheduling, invoicing, library and publication management, translation tracking, and communication via email and SMS. The system targets language school management, teachers, students, and HR personnel, serving over 95 schools across Central Europe. The website is professionally designed, multilingual, and includes client testimonials that reinforce its market credibility. Technically, the website employs modern web technologies such as Google Tag Manager, Google Analytics, Google Fonts, and popular JavaScript libraries like Swiper.js and Owl Carousel. It is mobile-optimized and structured for good SEO performance. However, there is no evidence of a CMS or hosting provider disclosed. The site includes cookie consent mechanisms and GDPR-related pages, indicating a baseline compliance with privacy regulations. From a security perspective, the site uses HTTPS and includes cookie consent but lacks explicit security headers and published security policies or incident response contacts. No vulnerabilities or malicious content were detected in the analysis. The absence of WHOIS data for the domain is a concern and reduces the overall trust score, though the website content and contact information appear legitimate. Overall, MyCat.cz presents a solid business offering with a professional web presence and moderate technical maturity. To enhance trust and security posture, the company should address the missing WHOIS data, publish security policies, and implement recommended HTTP security headers.

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

8 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

    • 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

  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

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

MyCat.cz operates in the education sector, focusing on language school management software delivered as a SaaS solution. Its competitive advantage lies in its comprehensive feature set tailored to language schools, including course management, invoicing, and communication tools. The business model is subscription or license-based software provision. The company targets small to medium-sized language schools in the Czech Republic and neighboring countries. Testimonials and client references indicate strong customer satisfaction and effective support services. The partnership with IMP Net for website development and cookie management suggests a collaborative ecosystem. Growth indicators include multi-country usage and continuous system development since 2010. The lack of WHOIS transparency is a risk factor but does not currently impact operational credibility.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and cookie consent implemented. However, it lacks visible HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options, which are recommended best practices. There is no published security policy or incident response contact information, which limits transparency and preparedness for security incidents. No vulnerability disclosures or security.txt files were found. The site does not expose sensitive data or use vulnerable libraries based on the analysis. Overall, the security maturity is adequate for a small SaaS provider but could be improved to meet higher compliance standards such as ISO 27001 or NIST frameworks.

Recommendations

  1. Verify and publish accurate WHOIS domain registration data to improve trustworthiness.
  2. Implement and configure HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  3. Publish a clear security policy and incident response contact information on the website.
  4. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Conduct regular security audits and penetration testing to identify and remediate potential vulnerabilities.

Technical notes

Notes

The website uses a modern and modular front-end technology stack including Google Fonts, Google Tag Manager, Google Analytics, Swiper.js, Owl Carousel, and UKit for UI components. The navigation is responsive and supports multiple languages. The site loads asynchronously loaded scripts for analytics and tag management, which is good for performance. However, no CMS or backend platform is explicitly identified. Hosting provider details are not disclosed. Performance is moderate with some heavy images in sliders but overall acceptable. Accessibility is basic with some ARIA roles implied by UKit but could be improved. SEO is supported by meta tags and structured navigation. The site could benefit from enhanced technical documentation and security hardening.
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.
