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

Riddle is a well-established SaaS platform founded in 2014, specializing in interactive content creation such as quizzes, polls, surveys, and minigames. It serves a diverse clientele including publishers, brands, sports teams, and marketers, positioning itself as a leader in engagement and lead generation tools. The platform offers extensive customization, team collaboration, and monetization options, supported by a strong brand presence and trusted by major organizations worldwide. Technically, the website demonstrates modern web development practices with a responsive design, accessibility compliance (WCAG 2.1), and integration of marketing and analytics tools like Google Tag Manager and CookieHub. The use of JSON-LD structured data enhances SEO and content discoverability. The platform emphasizes privacy and security, hosting data securely in the EU and maintaining ISO 27001 certification. Security posture is robust with HTTPS enforced, GDPR compliance, and no visible vulnerabilities or exposed sensitive data. However, the absence of WHOIS transparency slightly impacts trust but is understandable given privacy regulations. Overall, the site is professional, secure, and user-friendly, with comprehensive support and clear business information.

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.

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

Riddle operates in the technology sector, focusing on interactive marketing and engagement solutions. Its competitive advantage lies in unlimited content creation, deep customization, GDPR compliance, and personal customer support. Revenue streams include subscription plans ranging from Essential to Enterprise, with additional monetization through ad integration. The company targets medium to large organizations, including global brands and sports leagues, indicating a strong market presence and growth potential. Partnerships and integrations with major marketing tools enhance its ecosystem. The company maintains a consistent brand image and leverages testimonials and certifications to build trust.

Security posture

Riddle exhibits a mature security posture with adherence to GDPR and ISO 27001 standards, secure EU-based hosting, and encrypted data storage. The website uses HTTPS and avoids unnecessary tracking cookies, relying on explicit consent mechanisms. While security headers are not explicitly detected in the provided data, the overall approach to privacy and data protection is strong. No incident response or vulnerability disclosure information is publicly available, which could be improved. The platform's security practices align well with industry standards for SaaS providers handling personal data.

Recommendations

  1. Implement and publish comprehensive security headers such as Content-Security-Policy and X-Frame-Options to enhance protection against common web attacks.
  2. Provide clear incident response and vulnerability disclosure contacts or a security.txt file to improve transparency and trust.
  3. Regularly audit third-party scripts and integrations to ensure no vulnerable libraries are included.
  4. Enhance visibility of data retention policies and user data management practices on the website.
  5. Continue investing in accessibility and privacy features to maintain compliance with evolving regulations and standards.

Technical notes

Notes

The website is built using modern JavaScript frameworks (likely React) and employs SPA techniques for a smooth user experience. It integrates third-party services for analytics, cookie consent, and marketing automation, demonstrating a mature digital infrastructure. The site is mobile-optimized and accessible, with fast loading times and well-structured metadata for SEO. No CMS is explicitly detected, suggesting a custom or headless CMS solution. Hosting details are not explicit but EU-based data storage is confirmed. The technical setup supports scalability and robust performance for enterprise clients.
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.
