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.

Priority findings

1 finding rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

Matomo holds a strong position in the privacy-focused analytics market, leveraging open-source roots and compliance with European data protection laws to differentiate itself from competitors. Its business model combines open-source software with paid cloud and enterprise services. The target audience includes privacy-conscious businesses, regulators, and developers. The company benefits from certifications like ISO 27001 and maintains transparent security and privacy practices. Its partnership ecosystem includes privacy technology providers such as Usercentrics. Growth indicators include a well-maintained website, active social media presence, and comprehensive documentation. Strategic observations suggest continued focus on privacy innovation and compliance will sustain competitive advantage.

Security posture

Matomo exhibits a mature security posture with enforced HTTPS, presence of key security headers, and ISO 27001 certification. The website includes a dedicated security page detailing incident response and vulnerability disclosure processes, with direct contact emails for security and abuse. No vulnerable libraries or exposed sensitive data were detected in the analysis. The absence of DNSSEC is a minor gap but does not critically impact overall security. Privacy compliance is strong, with GDPR-aligned policies and consent mechanisms. The company demonstrates readiness for incident handling and maintains transparency about security practices, reflecting a security-conscious culture.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Continue regular security audits of third-party scripts and plugins to mitigate vulnerabilities.
  3. Maintain up-to-date CMS and plugin versions to reduce risk exposure.
  4. Enhance visibility of data retention policies to further improve privacy transparency.
  5. Consider publishing additional certifications or compliance attestations to strengthen trust.

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.
