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

Atlassian is a leading enterprise technology company specializing in collaboration software for software development, IT, and business teams. Their flagship products include Jira, Confluence, and Trello, which enable teams to organize, discuss, and complete shared work efficiently. The company operates a SaaS business model targeting a global audience of enterprises and teams, maintaining a strong market position as a trusted provider of productivity tools. The website reflects this with professional design, clear messaging, and comprehensive service offerings. Technically, Atlassian's website employs modern web technologies such as React and Node.js, with performance optimizations and mobile responsiveness. Security is robust, with HTTPS enforced, multiple security headers, and integration of Google reCAPTCHA for bot protection. The company maintains recognized certifications including ISO 27001 and SOC 2, and provides transparent security policies and incident response procedures. The security posture is strong, with no evident vulnerabilities or exposed sensitive data. Privacy compliance is well addressed with detailed privacy and cookie policies, GDPR adherence, and consent mechanisms. Contact information and business credentials are clearly presented, enhancing trustworthiness. The absence of WHOIS data is noted but likely due to registry or privacy policies rather than suspicious activity. Overall, Atlassian's digital presence demonstrates high maturity in business credibility, technical implementation, security, and privacy compliance. The website is safe for general audiences and aligns with enterprise standards. Strategic recommendations include maintaining up-to-date third-party components, continuous monitoring, and ongoing transparency in security disclosures to sustain trust and resilience.

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. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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.

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.
