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

CryptPad.fr is a French-based technology website offering an open-source, end-to-end encrypted collaboration suite. The platform targets users who prioritize privacy and secure online collaboration, providing services such as encrypted document editing and secure file sharing. The website is hosted by OVH, a reputable French hosting provider, and the domain has been active since 2014, indicating a mature project. The technical infrastructure leverages modern JavaScript libraries focused on cryptography and client-side encryption, demonstrating a commitment to security and privacy. From a security perspective, the site employs client-side encryption libraries but lacks visible security headers and published security policies, which could be improved. No forms or data collection mechanisms were detected in the analyzed HTML, reducing exposure to input-based vulnerabilities. However, the absence of privacy and cookie policies, as well as contact information, limits transparency and compliance with privacy regulations such as GDPR. Overall, the website is accessible without WAF or security challenges, but the content is minimal and primarily technical. The site shows moderate technical maturity and business credibility but would benefit from enhanced privacy compliance and clearer user communication. Strategic improvements in security headers, policy publication, and contact availability would strengthen 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

7 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

    • 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

  2. 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"

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

CryptPad operates in the niche market of privacy-focused collaboration tools, leveraging open-source software to provide encrypted online collaboration services. Its competitive advantage lies in client-side encryption, appealing to privacy-conscious users and organizations. The business model likely includes offering hosted services alongside the open-source software. The company targets individual users, teams, and organizations requiring secure collaboration. The domain age and hosting provider indicate stability and legitimacy. However, the lack of visible business contact details and policies suggests a lean operation or a community-driven project rather than a large commercial enterprise. Partnerships or subsidiaries were not identified, indicating an independent operation.

Security posture

The security posture of CryptPad.fr is moderate. The use of client-side encryption libraries such as TweetNaCl and Chainpad Crypto is a strong positive, ensuring data confidentiality before transmission. However, the absence of security headers (e.g., Content Security Policy, HSTS) and lack of published security or incident response policies reduce the overall security maturity. No vulnerability disclosures or security.txt files were found, limiting transparency for security researchers. The site does not appear to collect user data via forms, reducing attack surface. SSL configuration details were not provided but are assumed present given HTTPS usage. Overall, the site demonstrates good cryptographic practices but could improve in security policy communication and HTTP security headers.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Add security headers such as Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Publish a security policy and incident response plan, including contact channels for vulnerability reporting (e.g., security@ or abuse@ emails).
  4. Improve mobile optimization and accessibility to enhance user experience across devices and for users with disabilities.
  5. Consider adding analytics with privacy-respecting configurations to better understand user engagement while maintaining minimal tracking.

Technical notes

Notes

The website uses a modern JavaScript-based tech stack including RequireJS for module loading, jQuery for DOM manipulation, and cryptographic libraries such as TweetNaCl and Chainpad Crypto for client-side encryption. The hosting provider is OVH, a reputable European host. The site loads asynchronously with multiple scripts and CSS files, indicating modular design. Performance is moderate with basic mobile optimization and accessibility features. No CMS or backend platform was detected from the HTML. The site lacks structured data (JSON-LD) and advanced SEO optimizations. The absence of forms reduces complexity but also limits user interaction capabilities. Overall, the technical implementation is solid but could benefit from enhanced SEO, accessibility, and security header configurations.
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.
