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

Bottle is an established open source Python micro web-framework project founded in 2011 by Marcel Hellkamp. It targets Python developers seeking a lightweight, dependency-free framework for building web applications. The website serves as comprehensive documentation for the framework, including tutorials, API references, and plugin development guides. The project maintains a niche position in the Python ecosystem, emphasizing simplicity and minimalism. Technically, the site uses static HTML with internal JavaScript for documentation rendering and links to reputable Python-related external resources. The domain is registered with a reputable registrar since 2011, indicating stability and legitimacy. From a security perspective, the site lacks explicit privacy and cookie policies, security headers, and contact information, which lowers its privacy compliance and security posture scores. No forms or data collection mechanisms are present, reducing risk exposure. The absence of WAF or blocking mechanisms allows full content accessibility. The SSL configuration and security headers could not be fully assessed but should be verified and improved. Overall, the site is safe, professional, and trustworthy but would benefit from enhanced privacy and security disclosures. The overall risk is low given the nature of the site as documentation without user data collection. Strategic recommendations include publishing privacy and cookie policies, implementing security headers, enabling DNSSEC, and providing clear contact and incident response information to improve compliance and trust. These steps would enhance the security posture and user confidence without impacting the lightweight nature of the project.

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

9 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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 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

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.

Business context

Business profile

Bottle operates as a small, focused open source project serving the Python developer community. Its business model revolves around providing free software and documentation, likely supported by community contributions and indirect benefits such as reputation and ecosystem presence. The project targets developers needing a minimalistic web framework alternative to larger frameworks. The market position is stable within its niche, with a loyal user base. The project is self-managed by Marcel Hellkamp with no parent company or subsidiaries. The ecosystem includes links to GitHub, PyPI, and mailing lists, facilitating community engagement. Growth indicators include ongoing development (0.14-dev) and active documentation updates. The lack of commercial services or monetization is typical for open source projects. Strategic partnerships or sponsorships are not evident from the data.

Security posture

The website demonstrates a basic security posture appropriate for a documentation site with no user data collection. No forms or input fields reduce attack surface. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security is a gap. DNSSEC is not enabled, which could improve DNS integrity. SSL configuration details are not provided but HTTPS is implied by the URL. No incident response or vulnerability disclosure policies are published, limiting transparency. No contact channels for security issues are provided. The site does not track users or use analytics, reducing privacy risks. Overall, the security maturity is moderate but could be improved by adopting standard web security best practices and publishing relevant policies.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to improve privacy compliance and user trust.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Enable DNSSEC for the domain to enhance DNS security.
  4. Provide clear contact information and publish an incident response or vulnerability disclosure policy.
  5. Verify and enforce HTTPS with strong SSL/TLS configuration to ensure secure communications.

Technical notes

Notes

The website is a static documentation site generated likely by Sphinx, using internal JavaScript for enhanced user experience. The tech stack includes Python for the framework itself and JavaScript for client-side features. The site is hosted under a domain registered with Mesh Digital Limited and uses domaincontrol.com name servers. Performance is expected to be fast due to static content delivery. Mobile optimization and accessibility are basic but functional. SEO is basic with meta description and structured navigation. No CMS or third-party analytics detected, reducing complexity and privacy concerns. Technical risks are low but modernization opportunities include adding security headers and improving mobile responsiveness.
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.
