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

Dandelion Health is a healthcare technology company specializing in providing real-world data and a clinical AI marketplace to support innovators building healthcare AI solutions. Founded in 2020, the company targets life sciences and healthcare AI developers with a platform that combines multimodal real-world data and validated AI models. The website is professionally designed using Squarespace and includes sections for platform offerings, solutions, clinical areas, research, and company information. Social media presence includes LinkedIn and Twitter profiles, supporting business credibility. Technically, the website leverages modern web technologies including Squarespace CMS, Google Tag Manager, and Google reCAPTCHA for form security. Hosting is via AWS infrastructure, and the site enforces HTTPS with HSTS enabled, indicating a strong baseline security posture. However, DNSSEC is not enabled, and no explicit security or privacy policies are published, which are areas for improvement. Security posture is generally good with no detected vulnerabilities or exposed sensitive data. The site uses tracking technologies from Google and LinkedIn, indicating moderate user tracking but lacks visible cookie consent mechanisms or privacy policy disclosures, which may impact GDPR compliance. Contact information is limited to a contact form with no direct emails or phone numbers, reducing transparency. Overall, the website is safe, professional, and focused on healthcare AI data services. Strategic recommendations include publishing comprehensive privacy and cookie policies, enabling DNSSEC, adding vulnerability disclosure and incident response information, and improving transparency in contact details to enhance trust and compliance.

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 Policy found

      GDPR requires clear information about cookie usage

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

    • 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

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

Dandelion Health operates in the healthcare AI data sector, providing a platform that aggregates real-world data and validated AI models for clinical applications. Their market positioning is that of a niche data provider and platform operator catering to life sciences and healthcare innovators. The business model revolves around data services and a marketplace for clinical AI, likely generating revenue through data access subscriptions or platform usage fees. The company targets healthcare AI developers, life sciences companies, and clinical researchers. Growth indicators include recent product launches such as the Clinical AI Marketplace and partnerships with organizations like the American Heart Association AI Assessment Lab. The company maintains a professional online presence with active social media channels and a structured website, indicating a focus on credibility and market engagement.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and HSTS enabled, ensuring encrypted communications and protection against protocol downgrade attacks. The use of Google reCAPTCHA on forms mitigates automated abuse. However, the absence of DNSSEC leaves DNS queries vulnerable to spoofing. No explicit security policies, incident response contacts, or vulnerability disclosure mechanisms are present, which are important for transparency and compliance. Tracking technologies are used but without visible cookie consent, potentially exposing the company to privacy compliance risks under GDPR. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is good but could be enhanced by adding formal policies and DNS security.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to improve GDPR and privacy compliance.
  2. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  3. Add a security.txt file or a dedicated vulnerability disclosure page to facilitate responsible reporting.
  4. Provide explicit incident response contact information such as security@ or abuse@ email addresses.
  5. Increase transparency by adding direct contact emails and phone numbers for customer support.

Technical notes

Notes

The website is built on the Squarespace platform, leveraging its CMS capabilities for content management and hosting on AWS infrastructure. It uses modern JavaScript libraries including YUI and Moment.js, and integrates Google Tag Manager and LinkedIn Insight for analytics and marketing. The site is mobile optimized with responsive design and includes accessibility features at a basic level. Performance is moderate, typical for CMS-based sites with external scripts. SEO is supported by proper meta tags and Open Graph data. Technical risks include lack of DNSSEC and absence of explicit security and privacy policies. The site benefits from HTTPS and HSTS but could improve in transparency and compliance documentation.
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.
