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

3 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 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 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

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

thoughtbot operates a service-based business model focused on product design and development consulting. Their competitive advantage lies in over 20 years of experience, a strong client portfolio, and a transparent, collaborative approach. Revenue streams likely come from project engagements, team augmentation, and product management services. The company actively engages with the developer community through open source projects and content resources. Their partnership ecosystem includes social media platforms and content distribution channels. The company shows growth indicators through diverse service offerings and a global team distribution.

Security posture

The website demonstrates a solid security posture with HTTPS enabled and domain transfer protection. However, it lacks DNSSEC and explicit security headers, which are recommended for enhanced security. No sensitive data exposure or vulnerable libraries were detected. The absence of a published security policy, incident response contacts, or vulnerability disclosure policy suggests room for improvement in transparency and readiness. Privacy compliance is partially addressed with a comprehensive privacy policy but lacks a visible cookie consent mechanism. Overall, the security maturity is good but could be strengthened with additional policies and technical controls.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and publish a security policy and incident response contact information.
  3. Add explicit HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options.
  4. Deploy a visible cookie consent banner to enhance privacy compliance and user trust.
  5. Consider publishing a vulnerability disclosure policy and security.txt file to encourage responsible reporting.

Technical notes

Notes

The website uses a modern tech stack including Ruby on Rails and Hotwire for frontend interactivity. It employs SVG graphics, video content, and JSON-LD structured data for SEO and accessibility. Hosting and DNS are managed by reputable providers. Performance is fast with good mobile optimization and accessibility features. The site lacks a traditional CMS, indicating a custom or framework-based build. Visitor Analytics is used for tracking, but no major ad networks or affiliate programs are detected. The technical implementation is robust with minor opportunities for security and privacy enhancements.
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.
