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

Gratis-7kabale.dk is a Danish small business operated by Investing Classroom ApS, offering free online play of the classic 7-kabale (Klondike) card game. The website provides educational content about the game rules and allows users to play on multiple devices. The business model relies on advertising revenue, primarily through Google Adsense. The site is built on WordPress with modern plugins and themes, ensuring good SEO and mobile responsiveness. Security posture is adequate with HTTPS enabled and no exposed sensitive data, but lacks advanced security headers and incident response information. Privacy compliance is basic with privacy and cookie policies present but no active consent mechanism. Overall, the website is professional and trustworthy but could improve in security and privacy transparency.

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

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 company targets casual gamers and card game enthusiasts in Denmark and possibly globally, leveraging free access to attract traffic and monetize via ads. The market position is niche with a focus on a single popular card game. The business is newly founded in 2024, consistent with domain registration. The site shows consistent branding and clear company information including VAT number and physical address. No partnerships or subsidiaries are evident. Growth potential lies in expanding game offerings and improving user engagement. The advertising-supported model is common in free online gaming sites.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible vulnerabilities or sensitive data leaks. However, the absence of security headers such as Content-Security-Policy and lack of incident response contacts reduce its security robustness. There is no evidence of vulnerability disclosure or security policy documentation. GDPR compliance is partially met with privacy and cookie policies but lacks explicit consent mechanisms. The site would benefit from enhanced security controls and transparency to improve trust and compliance.

Recommendations

  1. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to mitigate common web attacks.
  2. Add explicit cookie consent mechanism to comply fully with GDPR requirements.
  3. Publish a security policy page and provide incident response contact information to improve transparency and readiness.
  4. Include verified company contact emails and phone numbers to enhance user trust and support.
  5. Regularly audit third-party scripts and advertising integrations to minimize privacy risks and improve performance.

Technical notes

Notes

The website uses a modern WordPress CMS with up-to-date plugins and themes, including Rank Math SEO and Ultimate Blocks, ensuring good SEO and content management capabilities. It loads Google Fonts and jQuery 3.7.1, and integrates Google Adsense for monetization. Performance is moderate with some optimization opportunities. Mobile responsiveness is good, and accessibility features are basic but present. No hosting provider details were found. The site uses structured data (JSON-LD) for SEO and rich snippets, enhancing search visibility. Technical risks include missing security headers and lack of advanced privacy controls.
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.
