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

HashBang is a Lyon-based cooperative specializing in bespoke web and software engineering services, founded in 2013. The company emphasizes sustainable and responsible digital solutions, leveraging Python and Django technologies. Their market position is that of a trusted local cooperative with a strong commitment to social and ecological values. Technically, the website uses modern frameworks such as Bulma CSS and Wagtail CMS, hosted on Scaleway infrastructure, indicating a moderate level of digital maturity with good mobile optimization and accessibility. Security posture is adequate with HTTPS usage but lacks explicit security headers and formal security policies. Privacy compliance is partial, with a privacy policy present only in the legal mentions page and no cookie consent mechanism. Overall, the website is professional, trustworthy, and content-rich, targeting French-speaking business clients seeking custom IT solutions.

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

8 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 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';…

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

HashBang operates as a cooperative in the technology sector, focusing on custom web projects and ERP tools. Their business model centers on collective decision-making and employee ownership, which differentiates them in the local market. Partnerships with regional cooperative and social economy organizations strengthen their ecosystem. The company targets SMEs and organizations valuing responsible digital transformation. Their content and service offerings suggest a stable, small-sized enterprise with growth potential in sustainable IT services. The absence of extensive marketing or tracking tools indicates a privacy-conscious approach aligned with their values.

Security posture

The website employs HTTPS, ensuring encrypted communications. However, the absence of key security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces protection against common web attacks. No vulnerability disclosures or incident response contacts are published, which could hinder rapid response to security issues. No signs of exposed sensitive data or vulnerable libraries were detected. The security posture is moderate but could be improved by implementing standard security headers, formalizing security policies, and adding vulnerability disclosure mechanisms.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against web attacks.
  2. Publish a clear cookie policy and implement a consent mechanism to improve privacy compliance and user trust.
  3. Develop and publish a formal security policy and incident response contact information to demonstrate security maturity.
  4. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Enhance SEO metadata completeness and consider adding analytics with privacy-respecting configurations to better understand user engagement.

Technical notes

Notes

The website is built on a modern technology stack featuring Python, Django, and Wagtail CMS, supported by Bulma CSS and FontAwesome for styling and icons. Hosting is provided by Scaleway, a reputable cloud provider. The site demonstrates good mobile responsiveness and accessibility features. Performance is moderate, with no major issues detected in the HTML structure or resource loading. The absence of analytics or tracking scripts suggests minimal data collection, aligning with privacy values. Opportunities exist to improve SEO and security headers to reduce technical risks and enhance user experience.
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.
