Security report for pub.dev
Google LLC · Technology · United States
Low risk. 1 critical or high finding in DNS health.
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.
Counted in this score

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.

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.
