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

YoYoCasino is an established online casino platform founded in 2017, targeting the Swedish market with a wide range of gambling services including slots, live casino games, jackpots, and classic table games. The website presents a professional and consistent brand image with a good quality user experience and mobile optimization. Technically, the site leverages modern web technologies such as AngularJS, Google Tag Manager, and Cloudflare DNS services, ensuring moderate performance and SEO optimization. Security posture is adequate with HTTPS enforced and bot protection via reCAPTCHA, though improvements are needed in DNSSEC implementation and security headers. Privacy compliance is limited due to the absence of explicit privacy and cookie policies. Overall, the platform is credible and trustworthy for its intended adult gambling audience.

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

5 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 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';…

  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

YoYoCasino operates in the online gambling sector, focusing on Swedish players with localized content and language. The business model revolves around providing a comprehensive casino gaming experience with a variety of games and jackpots. The company appears to maintain partnerships with responsible gambling organizations such as Spelpaus and Stödlinjen, indicating compliance with local regulations. Revenue streams likely include player deposits and game commissions. The platform uses third-party marketing and analytics tools to optimize user engagement. Growth indicators include a diverse game catalog and active promotions. No parent or subsidiary companies were identified from the data.

Security posture

The security maturity of YoYoCasino is moderate. The site uses HTTPS and Cloudflare DNS, which provide a solid foundation. The presence of Google reCAPTCHA helps mitigate automated abuse. However, the lack of DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options represents gaps that could be exploited. No incident response or vulnerability disclosure information is publicly available, which may hinder timely security issue reporting. Privacy policies and cookie consent mechanisms are missing, which could lead to compliance risks under GDPR. Overall, the platform should enhance its security framework and transparency to strengthen user trust and regulatory compliance.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve domain security.
  2. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  3. Add security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the website against common attacks.
  4. Publish a security policy and provide dedicated incident response contact channels (e.g., security@ or abuse@ emails).
  5. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.

Technical notes

Notes

The website is built using AngularJS framework with modern JavaScript modules and asynchronous loading of scripts for performance optimization. It integrates Google Tag Manager and Google Optimize for analytics and A/B testing. The hosting and DNS are managed via Cloudflare, providing CDN and security benefits. The site includes interactive elements such as sliders and animations using Splide.js and Lottie. Mobile optimization is good, with responsive design and viewport settings. However, accessibility features are basic and could be improved. The absence of CMS identification suggests a custom or proprietary platform. Performance is moderate, with room for optimization in script loading and caching strategies.
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.
