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

The website hjerterfri-gratis.dk is a small Danish online platform offering free access to the card game Hjerterfri (Hearts). It provides users with an embedded online game playable on multiple devices and includes informational content about the game rules and gameplay. The business model is ad-supported, primarily using Google Adsense to monetize the free gaming experience. The site targets Danish-speaking users interested in casual online card games. Technically, the site is built on WordPress with common plugins for SEO and content blocks, and it uses HTTPS for secure connections. The site is moderately optimized for mobile and SEO, with good content relevance and navigation clarity. However, it lacks privacy and cookie policies, contact information, and advanced security headers, which impacts its compliance and trustworthiness. The domain is newly registered in 2024, consistent with the site's launch and content.

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.

Priority findings

10 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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';…

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 site occupies a niche market in free online card games, focusing exclusively on Hearts. Its competitive advantage lies in offering a free, ad-supported game playable across devices without requiring downloads. The revenue stream is primarily advertising-based. The absence of contact details and formal policies suggests a small-scale operation with limited business transparency. The site does not appear to have partnerships or subsidiaries. Growth potential depends on expanding content, improving compliance, and enhancing user trust. The current ecosystem is simple, with reliance on Google Adsense for monetization.

Security posture

Security maturity is basic. The site uses HTTPS, which is mandatory and positive. However, no DNSSEC is enabled, and no security headers such as Content-Security-Policy or X-Frame-Options were detected, which could expose the site to certain web-based attacks. There are no visible forms collecting user data, reducing risk exposure. The lack of privacy and cookie policies indicates compliance gaps with GDPR. No incident response or security contact information is provided, limiting the site's readiness to handle security incidents. Overall, the security posture is functional but requires improvements to meet best practices and regulatory requirements.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  4. Add clear contact information including a security incident response contact or abuse email.
  5. Conduct a security audit to identify and remediate any hidden vulnerabilities and improve overall security posture.

Technical notes

Notes

The website is built on a modern WordPress platform using popular plugins such as Rank Math for SEO and Ultimate Blocks for content. It uses jQuery and Google Fonts for frontend functionality and styling. Google Adsense is integrated for advertising revenue. The site loads embedded content via iframe from a third-party game distribution service. Performance is moderate with no major errors detected. Mobile optimization is good, and SEO metadata is well implemented including Open Graph and JSON-LD structured data. However, the absence of advanced security headers and DNSSEC indicates some technical debt in security hardening. Hosting provider details are not explicitly identified. Overall, the technical infrastructure is adequate for a small-scale gaming site but could benefit from security and compliance modernization.
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.
