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

The website www.english-nns.cz/blog is an educational portal operated by NOVÁ ŠKOLA, s.r.o., focused on providing comprehensive English language teaching materials for primary schools and kindergartens in the Czech Republic. It offers textbooks, workbooks, multimedia interactive content, video demonstrations, and downloadable resources aligned with Czech educational standards. The site targets educators and teachers of young learners, supporting effective and engaging English language instruction. Technically, the site is built on WordPress with a moderate modern tech stack including Google Analytics and Tag Manager for tracking, and uses Google reCAPTCHA for form security. The site is mobile optimized and has good navigation and content quality. Security posture is solid with HTTPS and reCAPTCHA, but lacks security headers and explicit privacy and cookie policies, which are compliance gaps. WHOIS data is missing, which reduces trustworthiness and calls for further verification. Overall, the site is functional, professional, and safe for its audience but could improve privacy compliance and security best practices.

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. 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

      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

  2. Security headers

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.

Business context

Business profile

NOVÁ ŠKOLA, s.r.o. operates in the niche educational sector, specializing in English language learning materials for early education in the Czech Republic. Their business model combines content creation with e-commerce sales through an integrated e-shop. The company leverages multimedia and interactive content to differentiate itself and enhance teaching effectiveness. Their market position is focused and localized, serving educators primarily in Czech primary schools and kindergartens. The presence of social media channels and integration with external platforms like mediacreator.cz indicates a partnership ecosystem supporting content delivery. The company appears small-sized with consistent branding and a clear target audience. Revenue streams likely include sales of physical and digital teaching materials. Growth potential exists through expanding digital offerings and enhancing compliance and security to build trust.

Security posture

The website demonstrates a moderate to good security posture with mandatory HTTPS encryption and use of Google reCAPTCHA invisible to protect forms from abuse. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and others reduces defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published security policy, incident response contacts, or vulnerability disclosure mechanisms indicates limited transparency and preparedness for security incidents. Privacy compliance is weak due to missing privacy and cookie policies, which may expose the company to regulatory risks under GDPR. Overall, the security maturity is adequate for a small educational site but requires improvements to meet best practices and regulatory expectations.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to ensure GDPR compliance.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Maintain up-to-date WordPress core and plugins to mitigate vulnerabilities.
  4. Publish a security policy and incident response contact information to improve transparency and trust.
  5. Consider adding a security.txt file to facilitate vulnerability reporting and responsible disclosure.

Technical notes

Notes

The website is built on WordPress 5.2.21 with common plugins including Contact Form 7 and PDF Embedder, and uses jQuery 1.12.4. It integrates Google Analytics and Google Tag Manager for analytics and tracking, and Google reCAPTCHA invisible for form protection. The theme used is 'Preschool and Kindergarten' by Rara Theme. The site is mobile optimized with responsive design and uses FontAwesome icons. Performance is moderate, with no explicit performance optimization indicators found. SEO is supported by proper meta tags and canonical links. Accessibility is basic but could be improved. Hosting provider details are not disclosed. Overall, the technical infrastructure is standard for a small educational WordPress site 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.
