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

Canonical Ltd operates the website canonical.com/mir, promoting Mir, a fast, open, and secure display server designed for Linux-powered devices including desktops, IoT, and embedded products. The company holds a strong market position as a leading provider of Linux-based operating systems and infrastructure solutions, with a focus on enterprise and cloud markets. The website content is professionally crafted, targeting developers, device makers, and enterprises seeking modern graphical environments. Technically, the site employs modern web technologies, responsive design, and efficient performance, reflecting a mature digital infrastructure. Security posture is solid with HTTPS enforcement and domain registration protections, though improvements are recommended in DNSSEC adoption and security headers. Privacy compliance is currently weak due to the absence of explicit privacy and cookie policies. Overall, the website demonstrates high business credibility and trustworthiness, aligned with Canonical's established brand.

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.

Add-on

Leaked records that mention mir-server.io, from OffSeq Breach.

No leaked records found

Breach holds no records for mir-server.io right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Canonical's business model centers on open source software development, enterprise subscriptions, and cloud infrastructure services. The Mir display server is positioned as a key technology enabling next-generation user experiences across various Linux-powered devices. The company targets a broad audience including developers, enterprises, and IoT manufacturers. The domain's long registration history and consistent WHOIS data reinforce legitimacy. The website integrates with partner platforms such as Snapcraft and GitHub, indicating a strong ecosystem. Marketing and analytics tools are used moderately, with room for enhanced privacy transparency. The company maintains certifications relevant to security and compliance, supporting its enterprise focus.

Security posture

The website enforces HTTPS and uses domain status protections to prevent unauthorized changes. However, DNSSEC is not enabled, and security headers are not explicitly present, which could expose the site to certain attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a published security policy or incident response information limits transparency. Privacy policies and cookie consent mechanisms are missing, which may pose compliance risks under GDPR and similar regulations. Overall, the security posture is good but could be strengthened by adopting recommended best practices and improving privacy compliance.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Implement comprehensive privacy and cookie policies with clear consent mechanisms to ensure GDPR compliance.
  3. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web vulnerabilities.
  4. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  5. Regularly audit third-party scripts and analytics tools to minimize privacy risks and optimize performance.

Technical notes

Notes

The website uses modern HTML5, CSS3, and JavaScript technologies, including lazy loading for images and web fonts for consistent branding. It is mobile-optimized with responsive design and accessibility features. Google Tag Manager is used for analytics and marketing, indicating a mature digital marketing strategy. The site is hosted on a reliable infrastructure, likely managed by Canonical or a trusted cloud provider. Performance is fast with efficient resource loading. There is no detected CMS, suggesting a custom or static site architecture. Technical risks are minimal but include the lack of DNSSEC and security headers, which should be addressed to maintain robust security.
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.
