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

Rainfall Inc. operates a privacy-focused, decentralized personal AI platform that empowers users to control and monetize their personal data securely. The company targets individuals concerned with data privacy and the benefits of AI, positioning itself as an emerging player in the personal AI and data sovereignty market. The website is professionally designed with clear messaging, an invite-only waitlist, and multiple user engagement points such as contact forms and social media links. Technically, the site uses modern frontend technologies including React and Font Awesome, hosted with Google Domains DNS services. Analytics are implemented via Google Tag Manager and Google Analytics, with basic cookie consent mechanisms in place. Security posture is moderate with HTTPS enforced and privacy-by-design principles stated, but lacks DNSSEC and security headers, and no formal security or incident response policies are published. The domain is privacy protected but legitimately registered since 2019, consistent with a startup profile. Overall, the site is trustworthy, safe, and professionally maintained, though improvements in security transparency and DNS security are recommended.

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 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 Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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

  4. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Unregistered MX Record

      MX record points to unregistered domain: 6zvtpxmfdras64bcs2eefye2tlreembjmwdpfajvfsmawhfic6yq.mx-verification.google.com

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory

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

Rainfall is positioned as a technology startup focused on personal AI and data monetization, targeting privacy-conscious users globally. Its invite-only model suggests a controlled rollout strategy. The business model revolves around enabling users to earn from their data while maintaining privacy and control. The company maintains a presence on major social media platforms and provides clear contact channels. The lack of phone contact suggests a digital-first engagement approach. The company is small-sized, founded in 2019, with offices in Switzerland and the USA. No parent or subsidiary companies are indicated. The platform's focus on privacy and AI aligns with current market trends emphasizing data sovereignty and ethical AI. The company’s trust signals include privacy policies, cookie consent, and transparent data use statements.

Security posture

The website enforces HTTPS and states strong privacy and security principles such as on-device AI processing and data anonymization. However, the absence of DNSSEC and security headers like Content Security Policy or HSTS reduces the overall security posture. No published security policy or incident response plan is available, which limits transparency and preparedness perception. The use of privacy protection in WHOIS is justified for a startup. Google Analytics and Tag Manager are used, which require careful privacy management. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security maturity is moderate but can be improved by implementing recommended security headers, DNSSEC, and publishing formal security documentation.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and verify security headers such as Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a comprehensive security policy and incident response plan accessible on the website.
  4. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy and security risks.

Technical notes

Notes

The website is built using React framework with Font Awesome icons and uses Google Tag Manager and Google Analytics for tracking. The hosting DNS is managed via Google Domains with nameservers pointing to Google Cloud DNS. The site is mobile optimized with responsive design and uses modern CSS and JavaScript. Performance is moderate with no major issues detected. Accessibility features are basic but present. SEO optimization is basic with meta tags but no Open Graph or JSON-LD structured data detected. The site uses multiple modals and forms for user interaction, collecting minimal personal data (name and email) for waitlist and contact purposes. No CMS detected, likely a custom React SPA. Overall, the technical infrastructure is modern and adequate for the business needs but could benefit from enhanced SEO and accessibility improvements.
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.
