Risk levelLow

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

SonarSource is a technology company specializing in software security and code quality solutions, primarily through its flagship product SonarQube. The company targets developers, DevOps, and security teams by integrating advanced static application security testing (SAST), software composition analysis (SCA), infrastructure as code (IaC) scanning, and secrets detection into the developer workflow. SonarSource holds a strong market position as a leading provider of developer security tools with a professional and comprehensive online presence. Technically, the website is built using modern frameworks such as Gatsby and React, ensuring fast performance, mobile optimization, and good SEO practices. Security posture is robust with HTTPS enforcement, security headers, and no visible vulnerabilities or exposed sensitive data. Privacy compliance is well addressed with clear privacy and cookie policies and GDPR adherence. However, WHOIS data is missing, which slightly impacts transparency but does not detract from the overall legitimacy given the company's established reputation and certifications like ISO 27001. Overall, the website and business demonstrate a mature digital infrastructure and strong 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.

Priority findings

2 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

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

SonarSource operates in the technology sector, focusing on software security and quality assurance tools. Its business model revolves around providing software products and services that integrate into developer workflows, enhancing code security and quality. The company targets professional developers and security teams, positioning itself as a trusted leader in the static code analysis market. Revenue streams likely include software licenses, subscriptions, and enterprise support services. The company maintains a professional brand with consistent messaging and certifications that enhance trust. Partnerships and integrations with CI/CD tools and developer platforms are implied by the product focus. Growth indicators include a comprehensive website with multi-language support and active social media presence. The absence of WHOIS data is a minor concern but does not overshadow the company's market presence and operational maturity.

Security posture

The website demonstrates a high level of security maturity with HTTPS enforced and multiple security headers implemented, including HSTS, CSP, and X-Frame-Options. No exposed sensitive data or vulnerable libraries were detected in the analysis. Forms appear secure with no visible issues. The company holds ISO 27001 certification, indicating adherence to recognized information security management standards. However, explicit incident response and security policy pages are not prominently found, and no security.txt file is present, which could improve vulnerability disclosure transparency. GDPR compliance is evident through privacy and cookie policies. Overall, the security posture is strong with minor areas for improvement in transparency and incident response communication.

Recommendations

  1. Publish a dedicated incident response and security policy page to enhance transparency and trust.
  2. Implement and publish a security.txt file to facilitate responsible vulnerability disclosure.
  3. Provide clear contact information for a Data Protection Officer or security contact to improve compliance and user confidence.
  4. Continue monitoring and updating security headers and SSL configurations to maintain high security standards.
  5. Enhance marketing transparency by detailing data retention policies and user tracking practices.

Technical notes

Notes

The website is built on a modern technology stack using Gatsby, React, and JavaScript, which supports fast loading times and excellent mobile optimization. The use of Google Tag Manager indicates integration with analytics and marketing tools. The site employs CSS and modern web standards for accessibility and SEO optimization. No CMS detected, indicating a static site generation approach that reduces attack surface. Hosting provider details are not explicitly found. Performance is fast with good technical implementation. Opportunities exist to improve technical documentation around security policies and incident response. Overall, the technical infrastructure is robust and well-maintained, supporting the company's business objectives effectively.
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.
