Risk levelHigh

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

MarkerCS is a small non-profit organization focused on providing non-formal education training primarily for youth workers and teachers in Slovakia and the Czech Republic. Their website offers detailed information about their training programs, educational principles, and testimonials from past participants, positioning them as a niche educational provider supported by the Erasmus+ program. Technically, the website is built on WordPress using the Astra theme and Elementor page builder, hosted by a Czech registrar and hosting provider. The site is moderately performant, mobile-optimized, and SEO-friendly but lacks some advanced accessibility features. Security posture is adequate with HTTPS enabled and no visible vulnerabilities, but the absence of security headers and formal privacy and cookie policies indicates room for improvement. Overall, the website is professional and trustworthy but could enhance compliance and security transparency.

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

    • 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

  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';…

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

MarkerCS operates in the education and non-profit sectors, targeting professionals working with youth in informal and formal educational settings. Their business model revolves around delivering long-term training programs and providing methodological materials. Supported by Erasmus+, they maintain a credible presence with testimonials and partner logos. The organization appears to have a stable market position within its niche, focusing on quality and impact rather than scale. The website content and structure reflect a clear understanding of their audience and mission, though contact information is minimal, which could limit direct engagement opportunities.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is properly implemented, ensuring encrypted communications. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and others reduces protection against common web attacks. No vulnerability disclosure or incident response information is provided, which could hinder timely reporting and mitigation of security issues. The absence of privacy and cookie policies also indicates potential compliance gaps with GDPR and related regulations. No exposed sensitive data or vulnerable libraries were detected, suggesting good maintenance practices. Overall, the security posture is acceptable but would benefit from enhanced policies and technical controls.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  3. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Include incident response contact information such as security@ or abuse@ email addresses to improve transparency and readiness.
  5. Regularly audit and update WordPress core, themes, and plugins to mitigate risks from outdated software.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Astra theme and Elementor page builder, which are widely supported and regularly updated. The tech stack includes jQuery and Font Awesome for UI elements. Hosting is provided by a Czech registrar and hosting provider, REG-INTERNET-CZ, with nameservers indicating local infrastructure. Performance is moderate with lazy loading implemented for images, enhancing load times. SEO is supported by All in One SEO plugin with proper meta tags and Open Graph data. Mobile optimization is good, but accessibility features are basic and could be improved. No major technical debt or deprecated technologies were detected, indicating a well-maintained site.
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.
