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

7 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

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

ABCedu operates in the Slovak education sector as a small but focused publisher of educational materials and teacher training services. Their business model combines e-commerce sales of textbooks with educational seminars and online learning tools. The company targets students, teachers, and parents, leveraging endorsements from government bodies and positive customer reviews to build trust. Their partnership ecosystem includes recognized educational platforms and government registers. The website's structured content and clear navigation support their market positioning as a reliable educational resource. Growth indicators include active newsletter subscriptions and social media engagement. The company maintains a consistent brand image and professional content, supporting credibility and customer confidence.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and CSRF protection on forms. Use of Sentry for error tracking indicates proactive monitoring. Cookie consent mechanisms comply with GDPR requirements. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security represents a gap. No incident response or vulnerability disclosure information is publicly available, limiting transparency. The use of multiple third-party scripts increases the attack surface, necessitating regular audits. Overall, the security posture is adequate for the business type but could be strengthened by implementing recommended headers, publishing security policies, and establishing clear incident response channels.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy page including incident response contacts.
  3. Conduct regular security audits of third-party scripts and dependencies.
  4. Add a security.txt file to facilitate vulnerability disclosures.
  5. Enhance website accessibility to meet higher compliance standards.

Technical notes

Notes

The website is built on the CREATIVE shop CMS platform, utilizing modern JavaScript libraries such as jQuery and various tracking and analytics tools including Google Tag Manager, Google Analytics, Facebook Pixel, and Microsoft Clarity. Hosting leverages Cloudfront CDN for content delivery. The site uses asynchronous loading of scripts to optimize performance, though overall speed is moderate. SEO is supported by proper meta tags and Open Graph data. Mobile optimization is good with responsive design elements. Accessibility is basic but could be improved. The technical infrastructure supports a professional e-commerce and content delivery experience with room for modernization in security and accessibility.
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.
