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

The website www.denieuweschepenvandoeksen.nl is a Dutch-language content platform focused on the Plinko online casino game. It provides comprehensive guides, reviews, and casino recommendations targeted at Dutch-speaking online gamblers interested in Plinko. The site positions itself as a niche media provider with a small-scale business model centered on affiliate marketing and content monetization. Technically, the site uses modern web technologies including HTML5, CSS3, JavaScript ES modules, and integrates Google Analytics via Google Tag Manager. The site is mobile optimized with good SEO practices and structured data implementation. Security-wise, the site enforces HTTPS, uses CSRF tokens, and implements a cookie consent banner, but lacks explicit published security policies or incident response information. No critical vulnerabilities or suspicious content were detected. Overall, the site is professional, trustworthy, and compliant with GDPR-related cookie and privacy policies, though it could improve transparency on security and incident response. The domain uses privacy protection in WHOIS, which is justified given the gambling-related content. The site is safe for adults and does not contain explicit or NSFW content beyond gambling-related material.

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

4 findings rated critical or high. Fix these first.

  1. 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 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';…

  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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 business operates in the media sector, focusing on online gambling content specifically for the Plinko slot game in the Netherlands. It targets adult Dutch-speaking casino players by providing detailed game guides, reviews, and bonus offers. The business model appears to be content-driven affiliate marketing, leveraging SEO and structured data to attract organic traffic. The site maintains a consistent brand and trust signals such as DMCA protection and expert authorship. The absence of phone contact and limited social media presence suggests a lean operation. The company is small-sized with no parent or subsidiary companies identified. The site’s market position is niche but well-defined, catering to a specific gambling game audience.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and CSRF tokens implemented. Cookie consent mechanisms are in place supporting GDPR compliance. However, the absence of explicit security policies, incident response contacts, and security headers reduces the overall security maturity. No vulnerabilities or exposed sensitive data were found in the HTML content. The domain’s WHOIS privacy protection is appropriate for the gambling niche. Recommendations include adding security headers, publishing security and incident response policies, and implementing a vulnerability disclosure program to enhance trust and compliance.

Recommendations

  1. Implement and verify HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Consider adding a security.txt file or vulnerability disclosure page to facilitate responsible reporting.
  4. Enhance privacy compliance by detailing data retention policies and user data handling practices.
  5. Expand social media presence and contact options to improve business credibility and user trust.

Notes

The website uses a modern tech stack with ES module JavaScript, CSS3, and HTML5. Google Tag Manager and Google Analytics are integrated for tracking. The site is mobile optimized and uses structured data (JSON-LD) for SEO enhancement including FAQ and organization schema. No CMS or hosting provider details are evident from the HTML.

Overall, the technical implementation supports a good user experience and SEO performance.
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.
