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

The website oh.cz operates as a Czech business and economic magazine providing news, insights, and advice on business, finance, and competitiveness. It targets business professionals and the general public interested in these topics. The site is built on WordPress with a modern Newspaper theme and integrates Google Analytics for visitor tracking. The domain is well-established since 2004, indicating a mature presence in the Czech media landscape. Technically, the site uses standard plugins and scripts, with moderate performance and good mobile optimization. Security posture is adequate with HTTPS enabled but lacks explicit security headers and published security policies. Privacy compliance is limited due to the absence of visible privacy and cookie policies. Business credibility is supported by consistent branding and professional content, though contact information is limited to an email address. Overall, the site is functional and trustworthy but would benefit from enhanced privacy and security disclosures.

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

oh.cz positions itself as a niche Czech media outlet focusing on business and finance content. Its competitive advantage lies in specialized content for a Czech-speaking audience interested in economic topics. The business model appears to be content publishing monetized through advertising, as evidenced by ad placements and Google Ads integration. The site links to numerous partner domains, suggesting a networked ecosystem of related media outlets. Growth indicators include regular content updates and a stable domain age. However, the lack of detailed company information and contact channels may limit direct business engagement opportunities.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, ensuring encrypted communications. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. No security.txt or vulnerability disclosure mechanisms are present, which limits transparency and incident response readiness. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site would benefit from publishing clear security policies and incident response contacts to improve trust and compliance.

Recommendations

  1. Implement and enforce security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a comprehensive privacy policy and cookie consent mechanism to enhance GDPR compliance.
  3. Add a security.txt file and incident response contact information to facilitate vulnerability reporting.
  4. Expand contact information to include phone numbers and physical addresses for improved business credibility.
  5. Regularly audit and update all plugins and themes to mitigate potential vulnerabilities.

Technical notes

Notes

The site is built on WordPress 6.8.3 using the Newspaper theme and multiple plugins for newsletter, subscription, and content management. It uses jQuery 3.7.1 and integrates Google Tag Manager and Site Kit for analytics and marketing. Hosting is provided by Czech-based providers as indicated by nameservers. The site shows good mobile responsiveness and SEO optimization with proper meta tags and RSS feeds. Performance is moderate, with some room for improvement in loading speed and accessibility features. No critical technical debt or outdated libraries were detected in the provided HTML content.
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.
