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

ZA SKLEM o.s. is a Czech organization with an online presence primarily targeting Czech-speaking users. The website is built on WordPress using the Divi theme, indicating a moderate level of technical maturity. However, the absence of WHOIS registration data raises concerns about the domain's legitimacy or registration status. The site lacks critical compliance documents such as privacy policy and terms of service, and no direct contact information is provided, which impacts business credibility and user trust. From a security perspective, no advanced security headers or policies are detected, and SSL configuration details are unavailable, suggesting room for improvement in security posture. Overall, the website appears functional but basic, with significant gaps in compliance and trust indicators.

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

6 findings rated critical or high. Fix these first.

  1. 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"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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, YouTube, Google APIs

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

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 organization appears to be a small non-profit or community entity based in the Czech Republic, inferred from the '.o.s.' legal form and Czech language content. The business model is likely informational or advocacy-focused rather than commercial. There is no evidence of commercial services, certifications, or partnerships. The lack of contact details and business registration information limits the ability to assess market positioning or growth potential. The website's use of popular CMS and theme suggests a standard approach to digital presence without advanced customization or e-commerce capabilities.

Security posture

The security posture of the website is basic. The absence of security headers and unknown SSL configuration are notable weaknesses. No evidence of incident response contacts or security policies is found, which could hinder effective handling of security incidents. The lack of privacy and cookie policies compliant with GDPR or other regulations further exposes the organization to compliance risks. No vulnerabilities or malicious indicators are detected in the provided data, but the domain registration inconsistency is a critical concern. Enhancing security best practices and compliance documentation is recommended.

Recommendations

  1. Register or verify domain registration status to ensure legitimacy and avoid service disruption.
  2. Publish comprehensive privacy policy and terms of service pages to improve compliance and user trust.
  3. Implement standard security headers and enforce HTTPS site-wide to enhance security posture.
  4. Add clear contact information including emails and phone numbers for business and incident response.
  5. Regularly update CMS, themes, and plugins and conduct security audits to mitigate vulnerabilities.

Technical notes

Notes

The website uses WordPress CMS with the Divi theme and jQuery library, indicating a common and supported technology stack. The site appears moderately optimized for mobile devices and has a basic SEO setup with meta tags. Performance is moderate with no explicit indicators of slow loading or technical debt. However, the lack of detected security headers and unknown hosting provider details suggest potential risks. The site does not appear to use advanced analytics or marketing tools, which may limit business intelligence capabilities. Overall, the technical infrastructure is standard 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.
