Low risk. 2 critical or high findings in GDPR outside view.
The Python Package Index (PyPI) is a critical infrastructure platform operated by the Python Software Foundation, serving as the official repository for Python software packages. It enables developers to find, install, and publish Python packages, supporting the global Python community. The platform is well-established with a domain age since 2015 and strong backing by reputable sponsors such as AWS, Google, and Fastly, reflecting its market leadership and trustworthiness. Technically, PyPI employs a modern technology stack including JavaScript, CSS, and custom Python-based Warehouse software, hosted on AWS with Fastly CDN for performance optimization. The website is well-optimized for mobile and accessibility, with good SEO practices and fast performance. The use of HTTPS and reputable DNS providers enhances its security posture, although DNSSEC is not enabled. From a security perspective, PyPI demonstrates strong practices such as HTTPS enforcement and domain transfer protection. However, there is room for improvement by enabling DNSSEC, adding security headers, and publishing a security.txt file to facilitate vulnerability disclosures. No critical vulnerabilities or exposed sensitive data were detected. Overall, PyPI presents a high level of professionalism, security, and compliance with privacy policies. It is a trusted platform for Python developers worldwide. Strategic recommendations include enhancing DNS security, formalizing incident response information, and improving transparency around security policies to further strengthen trust and resilience.

NIS2 Art. 21(2)
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.

Each check with its score, findings and the evidence it collected.
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.

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.
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, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
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.
