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.

Business context

Business profile

Canonical Ltd. leverages Snapcraft.io as a strategic platform to extend its influence in the Linux ecosystem by providing a universal packaging format that simplifies software distribution and updates. The business model centers on enabling developers to reach millions of Linux users through the Snap Store, fostering a vibrant app ecosystem. The presence of major partners and verified publishers enhances market credibility and adoption. The platform supports a wide range of programming languages and application types, indicating a broad target audience from individual developers to enterprise software providers. Growth indicators include active community engagement via forums, extensive documentation, and integration with Canonical's broader product portfolio such as Ubuntu, MAAS, and Juju. The company’s approach to marketing and analytics reflects a data-driven strategy to optimize user acquisition and retention.

Security posture

Snapcraft.io exhibits a mature security posture with HTTPS enforced site-wide and integration of Sentry for real-time error monitoring. The presence of cookie consent dialogs and privacy policies indicates compliance with data protection regulations. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms suggests areas for enhancement in transparency and preparedness. DNSSEC is not enabled, which could improve DNS security. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. The site’s security score is strong but could be improved by adopting additional security headers and publishing formal security documentation. Overall, the platform balances usability with security, suitable for its role as a software distribution hub.

Recommendations

  1. Enable DNSSEC on the snapcraft.io domain to enhance DNS security and prevent spoofing.
  2. Implement and publish a formal security policy and incident response contact information to improve transparency and trust.
  3. Add security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options to harden the website against common attacks.
  4. Create and maintain a security.txt file to facilitate responsible vulnerability disclosure and improve security posture.
  5. Continue monitoring and updating third-party libraries and scripts to avoid introducing vulnerabilities.

It uses Raven (Sentry) for error tracking and Google Tag Manager for analytics and marketing integration. Images are optimized and lazy-loaded to improve load times. The site is mobile responsive and accessible, with semantic HTML and ARIA attributes for navigation. No CMS was detected, suggesting a custom or static site architecture. Hosting appears to be managed by Canonical or related infrastructure, ensuring reliability and performance. The technical implementation is robust with good SEO and accessibility practices, though security headers and DNSSEC could be improved. Overall, the technical infrastructure supports a fast, secure, and user-friendly 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.
