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

GOBL.org is a technology-focused website operated by Invopop Ltd., offering an open source global invoicing solution based on JSON Schema. The platform targets developers and businesses seeking compliant, efficient invoicing tools adaptable to various local tax regulations worldwide. The business model centers on open source community collaboration and providing developer toolkits, tax databases, and conversion utilities. The website is professionally designed, mobile-optimized, and hosted on Cloudflare with Hugo as the static site generator, reflecting a modern and performant technical infrastructure. Security posture is solid with HTTPS enforced and domain transfer protections, though improvements are needed in DNSSEC adoption and security header implementation. Privacy compliance is limited due to the absence of privacy and cookie policies, and no contact information is provided, which may affect user trust and regulatory adherence. Overall, the site is trustworthy and well-positioned in its niche but would benefit from enhanced transparency and security practices.

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

Business profile

Invopop Ltd. operates GOBL.org as a specialized technology provider in the invoicing and electronic business document space. The company leverages open source development to build a global invoicing standard in JSON, addressing the complexity of tax compliance across jurisdictions. Their competitive advantage lies in simplifying invoicing through a single format and conversion tools, appealing to developers and enterprises needing scalable solutions. The business ecosystem includes GitHub for code collaboration and Slack for community discussions. The company is small-sized, founded in 2010, and based in Spain. Revenue streams likely include consulting, support, or enterprise services around the open source project. The partnership ecosystem is limited but includes their own domain and GitHub presence. Strategic observations suggest growth potential by expanding compliance documentation and enhancing user engagement channels.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enabled and domain transfer protections in place. However, the lack of DNSSEC reduces DNS security robustness. No security headers were detected in the HTML content, which could expose the site to certain web-based attacks. There is no evidence of exposed sensitive data or vulnerable libraries. The absence of privacy and cookie policies indicates compliance gaps with GDPR and other privacy regulations. Incident response readiness is not demonstrated due to missing security contact information or vulnerability disclosure mechanisms. Overall, the security culture appears basic but functional, with room for improvement in policy transparency and technical hardening.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  3. Add standard security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security to harden the website against common attacks.
  4. Provide clear contact information for security incidents, including a dedicated security or abuse email address.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to facilitate responsible reporting and improve security posture.

Technical notes

Notes

The website is built using Hugo 0.85.0, a modern static site generator, ensuring fast performance and ease of maintenance. Hosting is provided by Cloudflare, offering reliable CDN and security features. The tech stack includes JSON Schema for data structure definitions and JavaScript for client-side functionality. The site is mobile-optimized with responsive design and uses external CSS and JavaScript resources efficiently. SEO is supported by proper meta tags and Open Graph metadata. However, the site lacks advanced accessibility features and security headers. No dynamic CMS or backend technologies are detected, reducing attack surface but limiting interactive capabilities. Overall, the technical infrastructure is modern, performant, and well-suited for the site's purpose but could benefit from enhanced security configurations and accessibility improvements.
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.
