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

1 finding 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.

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 targets healthcare professionals and organizations with a secure messaging service, leveraging Doctolib's brand. Its business model focuses on providing free secure communication tools, likely monetized through organizational subscriptions or integrations. The platform's market position is specialized within healthcare IT, emphasizing privacy and compliance. The website reflects a medium-sized enterprise with consistent branding and a clear value proposition. Partnerships with analytics and cookie consent providers indicate a commitment to privacy and data protection. Growth potential lies in expanding organizational adoption and enhancing security features. The lack of explicit contact information and WHOIS transparency suggests a focus on digital-first engagement rather than direct sales or support channels.

Security posture

The website demonstrates a good security baseline with HTTPS enforced and a comprehensive cookie consent mechanism aligned with GDPR. Use of Matomo analytics is privacy-conscious compared to other analytics platforms. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options is a gap. No public incident response or vulnerability disclosure policies were found, which could hinder rapid response to security issues. No exposed sensitive data or vulnerable libraries were detected in the provided content. The security score is good but could be improved by adopting additional headers and transparency measures. Overall, the security posture is appropriate for a healthcare communication platform but should evolve to meet higher compliance standards like NIS2 or ISO 27001.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Publish a dedicated incident response and vulnerability disclosure policy or security.txt file to enhance transparency and trust.
  3. Add explicit contact information for security and general inquiries to improve business credibility and compliance.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance accessibility features and provide a terms of service page to complete compliance and user trust.

Technical notes

Notes

The website uses a modern JavaScript stack including Alpine.js for reactive UI components and lazy loading for images, improving performance and user experience. Matomo analytics is integrated for privacy-friendly user tracking. Cookiebot manages cookie consent with granular user controls, reflecting strong GDPR compliance. The site is mobile-optimized with responsive design and good SEO metadata including Open Graph and Twitter cards. No CMS was detected, suggesting a custom or static site architecture. Hosting provider details are not explicit. Performance is moderate with asynchronous script loading. Accessibility is basic but functional. Overall, the technical infrastructure supports a secure, user-friendly healthcare communication platform with opportunities for further optimization and security hardening.
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.
