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

Buildbot is an established open-source continuous integration framework founded in 2006, designed to automate software build, test, and release processes. It targets developers and organizations requiring flexible and scalable CI/CD solutions, with a strong presence in the open-source community and usage by notable projects such as WebKit and Python. The website provides comprehensive technical content, tutorials, and links to source code repositories, reflecting a mature and focused business model centered on software automation frameworks. Technically, the site uses a moderate technology stack including jQuery and Bootstrap, with Python and Twisted forming the backend framework. The site is functional with good design and navigation but lacks modern mobile optimization and advanced SEO features. Security posture is moderate; while domain registration is stable and protected, the website lacks visible HTTPS enforcement, security headers, and published privacy or cookie policies, which are critical for compliance and trust. No contact or incident response information is provided, limiting direct communication channels. Overall, the site is trustworthy and professional but would benefit from enhanced security and privacy compliance measures.

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

10 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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"

    • 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';…

  3. 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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Buildbot occupies a niche in the continuous integration and software automation market, competing with tools like Jenkins and CruiseControl but differentiating itself through flexibility and extensibility. Its open-source nature and community-driven development model support adoption by diverse projects and organizations. Revenue streams are likely indirect, possibly through consulting or support services. The target customers are software developers and teams requiring customizable CI/CD pipelines. The project demonstrates growth and sustainability through active GitHub engagement and documentation. Partnerships are primarily community-based, with no explicit commercial partners identified. The business operates with a small team or community contributors, focusing on technical excellence and open collaboration.

Security posture

The security maturity level is moderate but with notable gaps. The domain is well-registered with transfer and update protections, indicating good domain security hygiene. However, the website lacks HTTPS enforcement visible in the HTML content, no security headers are detected, and no privacy or cookie policies are published, which are essential for GDPR and general data protection compliance. No vulnerability disclosure or security.txt files are present, and no incident response contacts are provided, limiting the ability to report security issues. The absence of forms reduces attack surface but also limits user interaction. Overall, the security posture is adequate for an informational open-source project site but requires improvements to meet modern security and privacy standards.

Recommendations

  1. Implement HTTPS with strong SSL/TLS configuration and enforce HSTS to secure all traffic.
  2. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  4. Create and publish a vulnerability disclosure policy or security.txt file with clear contact information.
  5. Add visible contact information for general and security-related inquiries to enhance communication and trust.

Technical notes

Notes

The website uses a traditional tech stack with jQuery 3.1.1 and Bootstrap 3.3.7, which are somewhat dated but still functional. The backend framework is Python-based using Twisted, suitable for asynchronous job scheduling. The site is moderately performant with basic mobile responsiveness and accessibility features. SEO is basic with meta description but lacks advanced structured data or Open Graph tags. Hosting details are not explicit but DNS servers include he.net and others. No CMS detected, indicating a custom or static site approach. Technical debt is moderate due to older frontend libraries and lack of modern security practices. Opportunities exist to modernize frontend frameworks, improve mobile optimization, and enhance SEO and accessibility compliance.
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.
