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

8 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. 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

    • 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 company operates in the technology sector, focusing on AI-driven image generation services. Its business model revolves around providing free and paid access to Stable Diffusion XL-powered image generation, supplemented by a large prompt database and mobile app offerings. The platform appeals to creatives, hobbyists, and professionals seeking quick and high-quality AI art generation. Market positioning is as an accessible and user-friendly service with a growing feature set. The company is relatively new, founded in 2022, and maintains transparency in domain registration. No direct contact details or extensive corporate information are provided, which is typical for small tech startups. The partnership ecosystem includes Google services for authentication and analytics, with Cloudflare providing DNS and likely hosting support.

Security posture

The website enforces HTTPS and uses clientTransferProhibited status on its domain to prevent unauthorized transfers, indicating good domain security practices. However, DNSSEC is not enabled, which is a recommended enhancement. No security.txt or vulnerability disclosure policies are published, limiting transparency in incident response. The site claims no personal data collection, enhancing privacy but lacks cookie consent banners, which may be a compliance gap. No exposed sensitive data or vulnerable libraries were detected in the analysis. Overall, the security maturity is moderate with room for improvement in formal policies and DNS security.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement a cookie consent mechanism to comply with GDPR and other privacy regulations.
  3. Publish a detailed security policy and incident response plan accessible to users.
  4. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Enhance accessibility features to improve compliance and user experience for all users.

Technical notes

Notes

The website is built using modern web technologies including Next.js and React, with optimized font loading and image delivery (WebP format). It uses Cloudflare DNS and Google Identity Services for authentication. Performance is fast with responsive design and mobile optimization. SEO is well addressed with proper meta tags and canonical links. No CMS is detected, indicating a custom or framework-based solution. The technical stack is current and well implemented, supporting a smooth user experience. However, the absence of cookie consent and security.txt files indicates some technical compliance gaps.
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.
