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

Happy Diffusion is an AI-driven platform specializing in generating high-quality adult images using Stable Diffusion technology. It targets an adult audience seeking customizable and realistic AI-generated content, offering a free-to-use model with fast performance powered by dedicated NVIDIA A100 GPUs. The platform emphasizes user privacy by deleting generated images after sessions and supports multiple AI models. Technically, the website is built on modern frameworks like React and Next.js, ensuring good performance and mobile optimization. However, the absence of WHOIS registrant data raises some trust concerns, although the site maintains professional design and clear contact channels. Security posture is decent with HTTPS but lacks some advanced headers and incident response disclosures. Overall, the platform is functional and well-positioned in the niche adult AI content market but could improve transparency and security practices.

NIS2 Art. 21(2)

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

7 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. 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';…

  3. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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 technology sector, focusing on AI-generated adult content. It leverages advanced GPU hardware to deliver fast image generation and supports a wide range of AI models, including custom models from Civitai. The business model appears freemium with potential paid upgrades. The target market is adults interested in AI art and adult content creation. The company maintains a clear online presence with privacy policies and contact emails but lacks detailed corporate information or physical addresses. The platform's competitive advantage lies in speed, privacy, and model variety. Partnerships with model providers like Civitai enhance its ecosystem. Growth indicators include a large user base and millions of images generated. Strategic observations suggest focusing on compliance, security, and expanding trust signals to strengthen market position.

Security posture

The website enforces HTTPS and promotes privacy by deleting user-generated images after sessions, which is a strong security practice. However, it lacks visible security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate common web attacks. There is no published security policy or incident response plan, and no vulnerability disclosure or security.txt file is found. The absence of WHOIS registrant data is a red flag for domain legitimacy. No signs of malware or phishing were detected. Overall, the security maturity is moderate but could be significantly improved by adopting standard web security headers, publishing security policies, and enhancing transparency around incident handling.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response plan on the website.
  2. Add standard security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to improve web security.
  3. Introduce a cookie consent banner and detailed cookie policy to enhance privacy compliance.
  4. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Improve WHOIS transparency or provide verified domain registration details to increase trustworthiness.

Technical notes

Notes

The website uses a modern technology stack based on React and Next.js, enabling server-side rendering and good SEO. It leverages Automatic1111 Web UI for AI model integration and uses high-performance NVIDIA A100 GPUs for image generation. The site is mobile optimized and loads quickly with proper meta tags and Open Graph data for social sharing. There is no detected CMS, indicating a custom or framework-based build. No hosting provider details are explicitly found. Accessibility is basic but functional. Technical risks include missing security headers and lack of detailed compliance mechanisms. Opportunities exist to enhance security and privacy features to reduce technical debt and improve user trust.
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.
