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

    • 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

The business targets language schools and related stakeholders, offering a SaaS model for administrative and educational management. Its competitive advantage lies in its specialized focus on language education, integration of multiple administrative functions, and a user base of over 70 schools. The company emphasizes customer support and continuous development based on client feedback. Revenue likely derives from subscriptions or licenses for the MyCat system. The presence of multiple satisfied client testimonials and a clear contact structure indicates a stable operational model with growth potential in the regional education technology sector.

Security posture

The website employs HTTPS and includes cookie consent mechanisms, indicating baseline compliance with privacy regulations. However, no explicit security headers were detected in the HTML source, and no incident response or vulnerability disclosure information is provided. The absence of WHOIS data raises concerns about domain registration transparency, which could impact trust. The use of third-party analytics and tag management tools is standard but requires ongoing monitoring for privacy compliance. Overall, the security posture is moderate but could be improved by implementing security headers, publishing incident response contacts, and ensuring domain registration transparency.

Recommendations

  1. Implement and verify HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy and incident response contact information to enhance transparency and trust.
  3. Regularly audit third-party scripts and analytics tools for privacy compliance and security risks.
  4. Investigate and resolve the missing WHOIS data issue to improve domain legitimacy and trustworthiness.
  5. Enhance accessibility features to improve compliance and user experience for all users.

Technical notes

Notes

The website uses a modern front-end stack including Google Fonts, Google Tag Manager, Google Analytics, Swiper Slider, Owl Carousel, and UIkit framework for UI components. The site is responsive and optimized for mobile devices with good navigation clarity. Performance is moderate, with asynchronous loading of analytics scripts. No CMS or hosting provider information is explicitly detected. The site lacks visible security headers in the HTML source, which may indicate a need for server-side configuration improvements. Overall, the technical implementation is solid but could benefit from enhanced security and accessibility 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.
