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

2 findings rated critical or high. Fix these first.

  1. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Flatiron Health UK operates as a specialized branch of the US-based Flatiron Health, targeting the UK healthcare sector, particularly NHS hospitals and cancer research communities. The business model centers on leveraging electronic health records to generate high-quality real-world evidence, supporting regulatory decisions, health technology appraisals, and expanding treatment alternatives. The company positions itself as a key player in healthcare data science with strong partnerships and a focus on improving cancer care. The website content and external links reinforce its market position and credibility. No direct contact details or extensive business registrations are published on the site, which is typical for a branch entity.

Security posture

The website employs HTTPS and integrates cookie consent via Civic Cookie Control, indicating compliance with privacy regulations. Security headers are implied but not explicitly documented. No vulnerabilities or exposed sensitive data were detected in the HTML content or scripts. However, the absence of published security policies, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. The use of reputable third-party services like HubSpot and Google Tag Manager supports a secure and stable infrastructure. Overall, the security posture is good but could benefit from enhanced documentation and explicit policies.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the website footer or main navigation.
  2. Add a dedicated security policy page detailing frameworks, certifications, and incident response procedures.
  3. Implement and publish a security.txt file to facilitate vulnerability disclosures.
  4. Provide clear contact information for security incidents, including dedicated security or abuse email addresses.
  5. Regularly review and update security headers and third-party scripts to maintain a strong security posture.

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.
