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

RandomNumberGenerator.com is a niche utility website operated by DLC Websites since 1999, providing free random number generation tools primarily for lottery and gaming purposes. The site offers customizable random number tables and educational content about randomness. It is monetized through Google AdSense advertising and maintains a simple, functional design with basic mobile responsiveness. The website does not collect personal data or provide contact information, privacy policies, or terms of service, which limits its compliance posture. Technically, it uses standard web technologies including HTML, CSS, JavaScript, and Google Ads scripts. Security posture is moderate with no visible security headers or advanced protections, and the random number generation relies on JavaScript's Math.random(), which is not cryptographically secure but sufficient for casual use. Overall, the site is legitimate and consistent with its domain registration data but would benefit from improved privacy and security practices.

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

6 findings rated critical or high. Fix these first.

  1. 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

  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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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 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';…

  4. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

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 website targets general users seeking random numbers for games and lotteries, positioning itself as a free, easy-to-use utility. Its competitive advantage lies in its longevity and simplicity. Revenue is generated via advertising, with no direct sales or subscriptions. The site maintains partnerships with related utility sites, enhancing its ecosystem. Growth indicators are limited due to the static nature of the service. The business model is straightforward, focusing on providing a free service supported by ads. Strategic observations suggest opportunities to expand services or improve compliance to increase trust and user engagement.

Security posture

The current security maturity is basic. The absence of privacy and cookie policies, lack of security headers, and no visible incident response or vulnerability disclosure mechanisms indicate gaps in compliance and security best practices. The use of non-cryptographically secure RNG is a minor concern given the site's purpose. No sensitive data collection reduces risk exposure. Incident response readiness and security culture indicators are not evident. Compliance with GDPR or other regulations is not demonstrated. Overall, the security posture is functional but could be significantly improved by implementing standard policies, security headers, and secure data handling practices.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve compliance and user trust.
  2. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Ensure HTTPS is enforced site-wide and verify SSL/TLS configuration for best practices.
  4. Consider using a cryptographically secure RNG for applications requiring higher security assurances.
  5. Provide clear contact information and incident response channels to enhance transparency and security readiness.

Technical notes

Notes

The website uses a simple technology stack with HTML, CSS, and JavaScript, supplemented by Google AdSense for monetization. The site is moderately optimized for performance and mobile devices but lacks advanced accessibility features. No CMS or modern frameworks are detected, indicating a static or custom-built site. The absence of security headers and privacy mechanisms suggests technical debt in security and compliance areas. The site could benefit from modernization efforts including responsive design improvements, enhanced SEO, and integration of privacy and security best practices to reduce risks and improve user experience.
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.
