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

JAHHO.cz is a Czech internet portal providing a categorized web directory, entertainment content such as wallpapers and GIFs, and additional services like TV program listings and search functionality. The site targets a general Czech-speaking audience seeking online entertainment and curated web resources. The business model revolves around advertising revenue, primarily through Google Adsense, and providing a free portal service. The website appears to be a small-scale operation managed by the JAHHO team since 2003, with a basic but functional online presence. Technically, the site uses standard web technologies including HTML, CSS, and JavaScript, with integrations of Google Adsense for advertising and Piwik (Matomo) for analytics. The site is served over HTTPS, ensuring basic transport security, but lacks advanced security headers and modern CMS or frameworks. Performance and mobile optimization are moderate, with room for improvement in accessibility and SEO best practices. From a security perspective, the site has a basic posture with HTTPS enabled but no evident security policies, privacy or cookie notices, or incident response contacts. The absence of WHOIS data for the domain raises concerns about domain legitimacy and transparency. No critical vulnerabilities or adult content were detected, but the site would benefit from enhanced security headers, privacy compliance measures, and clearer contact information. Overall, JAHHO.cz is a modest, general-audience web portal with basic technical and security implementations. Strategic improvements in privacy compliance, security hardening, and domain registration transparency are recommended to enhance trust and compliance.

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

  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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. 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';…

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

Business profile

JAHHO.cz operates as a general Czech internet portal offering categorized links and entertainment content, positioning itself as a niche web directory and entertainment hub. Its competitive advantage lies in its long-standing presence since 2003 and a broad category coverage including auto, culture, computers, travel, business, society, education, and news. Revenue streams are primarily advertising-based, leveraging Google Adsense. The target customer segment is Czech internet users seeking curated web content and entertainment. The partnership ecosystem includes service providers like NetSystems for web services and Shopsystem for e-commerce solutions. Growth indicators are limited due to lack of detailed business data. The portal's operations appear small-scale and focused on maintaining a stable user base rather than aggressive expansion.

Security posture

The security maturity of JAHHO.cz is basic. The site uses HTTPS, which is mandatory for secure communications, but lacks important security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options that help mitigate common web attacks. There is no evidence of privacy or cookie policies, which is a compliance gap under GDPR. No incident response or security contact information is provided, limiting the ability to report or respond to security issues. The use of third-party scripts like Google Adsense and Piwik introduces potential risks if not regularly audited. No exposed sensitive data or vulnerabilities were detected in the content analysis. Overall, the site would benefit from implementing security best practices and compliance documentation to improve its security posture.

Recommendations

  1. Implement comprehensive privacy and cookie policies to comply with GDPR and improve user trust.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web vulnerabilities.
  3. Establish clear contact channels for security incident reporting and data protection inquiries.
  4. Regularly audit and update third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Improve mobile optimization and accessibility to enhance user experience and SEO performance.

Technical notes

Notes

The website is built using traditional web technologies including HTML, CSS, and JavaScript, with no modern CMS or frameworks detected. It integrates Google Adsense for advertising and Piwik (Matomo) for analytics tracking. The site is served over HTTPS, ensuring encrypted communication. Performance is moderate with basic mobile responsiveness and accessibility features. SEO is basic with meta keywords and description present but no advanced structured data or Open Graph tags. The site lacks modern technical enhancements such as progressive web app features or advanced caching. Hosting provider details are not discernible from the content. Overall, the technical infrastructure is functional but dated, with opportunities for modernization and performance optimization.
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.
