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

OnlyU is a Czech-language media website focused on publishing articles related to relationships, society, and health. The site targets Czech-speaking users interested in these topics and monetizes primarily through advertising networks such as Google Adsense and Taboola. The website is built on WordPress CMS and integrates multiple third-party analytics and marketing tools, including Google Analytics, Gemius, and ShareThis, indicating a mature digital marketing infrastructure. However, the absence of publicly available WHOIS data limits the ability to fully verify domain ownership and legitimacy. The site implements a cookie consent banner, showing some compliance with GDPR requirements, but lacks an explicit privacy policy or terms of service in the analyzed content. Technically, the site shows moderate performance and good mobile optimization but has minor backend issues such as visible PHP warnings. Security posture is moderate with HTTPS enabled but missing security headers and some code hygiene issues. Overall, the website is functional and professionally presented but would benefit from improved transparency, security hardening, and compliance documentation.

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

8 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

  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"

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

OnlyU operates as a niche media content provider in the Czech Republic, focusing on lifestyle topics. Its business model relies on content publishing supported by advertising revenue from major ad networks and tracking services. The site leverages common digital marketing and analytics tools to optimize user engagement and ad targeting. The lack of clear business registration or contact information on the site reduces direct trust signals. The partnership with advertising and tracking platforms like CPEx and Seznam SSP suggests integration into local advertising ecosystems. Growth potential depends on content quality and audience engagement in the Czech market. Strategic improvements in transparency and compliance could enhance credibility and user trust.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is properly implemented, 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. The visible PHP warning in the HTML source indicates potential information leakage and code quality issues that should be addressed. The site uses multiple third-party scripts, increasing the attack surface and requiring vigilant update and monitoring practices. No explicit incident response or security policy information is found, suggesting limited formal security governance. Overall, the site is functional but would benefit from enhanced security controls and code hygiene.

Recommendations

  1. Fix all PHP warnings and errors to prevent information leakage and improve code quality.
  2. Implement and configure essential security headers (CSP, X-Frame-Options, X-Content-Type-Options) to harden the website against attacks.
  3. Publish a clear and comprehensive privacy policy and terms of service to improve compliance and user trust.
  4. Regularly update WordPress core, themes, and plugins to mitigate vulnerabilities.
  5. Establish and communicate incident response procedures and security policies to enhance security culture and readiness.

Technical notes

Notes

The website is built on WordPress CMS with a child theme 'soledad-child' and uses a variety of modern web technologies including jQuery, Popper.js, Google Tag Manager, and multiple advertising and tracking scripts. The site loads asynchronously many third-party scripts for analytics and advertising, which may impact performance but enable detailed user tracking and monetization. The presence of PHP warnings suggests some technical debt or misconfiguration in the backend code. SEO is supported by Yoast plugin with proper meta tags and Open Graph data. Mobile optimization is good with responsive design and video embedding support. Accessibility is basic but could be improved. Hosting provider details are not evident from the data. Overall, the technical infrastructure is standard for a content-driven WordPress site but requires backend code fixes and security enhancements.
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.
