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

Pub.dev is the official package repository for the Dart programming language and Flutter framework, operated by Google LLC. It serves as a central platform for developers to find, publish, and manage reusable libraries and packages, supporting the vibrant Dart and Flutter ecosystems. The website is positioned as a trusted and authoritative source, featuring curated Flutter Favorites, trending packages, and top Dart packages, targeting software developers and organizations using Dart and Flutter technologies. Technically, the site leverages modern web technologies including Dart-based frameworks, Google Tag Manager, Google Analytics, and Material Design CSS. It is hosted on Google infrastructure, ensuring high performance, fast loading times, and excellent mobile optimization. The site is well-structured with comprehensive metadata, Open Graph tags, and JSON-LD structured data to enhance SEO and accessibility. From a security perspective, pub.dev demonstrates a strong posture with enforced HTTPS, multiple security headers, and a cookie consent mechanism compliant with GDPR. However, it lacks a publicly visible vulnerability disclosure policy or security.txt file and does not provide explicit incident response contact channels. No vulnerabilities or exposed sensitive data were detected in the analysis. Overall, pub.dev is a highly professional, secure, and trustworthy platform with excellent content quality and technical implementation. Strategic recommendations include publishing a formal vulnerability disclosure policy, enhancing incident response transparency, and continuing to maintain strong privacy compliance to further strengthen trust and security culture.

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.

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

Pub.dev operates as a critical infrastructure component within the Dart and Flutter developer ecosystems, providing essential package management services. Its market position is strong as the official repository backed by Google, which lends significant credibility and trust. The business model revolves around platform service provision without direct monetization visible on the site, focusing on community and ecosystem support. Target customers are primarily software developers and organizations building Dart and Flutter applications. The platform benefits from strategic partnerships with Flutter and Dart official sites and integrates with Google’s broader developer tools ecosystem. Growth indicators include curated package lists and active community engagement through GitHub issue tracking and YouTube educational content. The site’s operations reflect a mature, enterprise-level service with consistent branding and high content quality.

Security posture

The security maturity of pub.dev is high, with HTTPS enforced and multiple security headers implemented to protect users. The presence of a cookie consent bar indicates awareness of privacy regulations such as GDPR. No critical vulnerabilities or exposed sensitive data were found. However, the absence of a public vulnerability disclosure policy or security.txt file and lack of explicit incident response contact information represent areas for improvement. The site’s use of Google-managed analytics and tag management is standard but requires ongoing privacy compliance vigilance. Overall, the platform demonstrates a robust security culture appropriate for an enterprise-grade service but could enhance transparency and responsiveness to security incidents.

Recommendations

  1. Publish a formal vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  2. Provide clear incident response contact channels, such as security@ or abuse@ email addresses, to improve transparency and responsiveness.
  3. Maintain and regularly update privacy compliance measures, including cookie consent and data retention policies.
  4. Enhance user trust by displaying security certifications or compliance frameworks if applicable.
  5. Continue investing in technical modernization and accessibility improvements to sustain high performance and user experience.

Technical notes

Notes

The website is built using Dart and JavaScript technologies, leveraging Google Tag Manager and Google Analytics for tracking and marketing insights.

The site is hosted on Google infrastructure, contributing to fast load times and reliable uptime. The HTML is valid and well-structured, with comprehensive meta tags and structured data for SEO. Accessibility features are present, and the site is mobile-optimized. No CMS was detected, indicating a custom or proprietary platform. Technical risks are minimal, with no outdated or vulnerable libraries identified. Opportunities exist to further enhance security transparency and incident response capabilities.
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.
