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

3 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Business profile

Atlassian Pty Ltd operates Bitbucket as part of its suite of developer tools, targeting software development teams and enterprises globally. The business model is SaaS subscription-based, with premium tiers offering advanced governance and AI features. Bitbucket integrates deeply with Jira and other Atlassian products, creating a strong ecosystem advantage. The company is positioned as a market leader, supported by Gartner recognition and extensive partner integrations. Growth indicators include AI-powered features and cloud migration incentives. The website content and testimonials reinforce Bitbucket's value proposition in accelerating software delivery and collaboration.

Security posture

The website enforces HTTPS and uses domain status locks to prevent unauthorized changes, indicating a mature security approach. Cookie consent is managed via OneTrust, supporting privacy compliance. However, no explicit security policy, incident response contacts, or vulnerability disclosure mechanisms were found, which are recommended for transparency and trust. DNSSEC is not enabled, representing a potential area for DNS security improvement. No exposed sensitive data or vulnerable libraries were detected in the provided content. Overall, the security posture is good but could be enhanced with more explicit policies and DNS security.

Recommendations

  1. Enable DNSSEC to improve DNS integrity and security.
  2. Publish clear privacy policy and terms of service links prominently on the website.
  3. Add a dedicated security policy page including incident response and contact channels.
  4. Implement and publish a vulnerability disclosure policy and security.txt file.
  5. Include explicit security headers (CSP, HSTS, X-Frame-Options) to strengthen web security.

Technical notes

Notes

The website uses a modern tech stack including JavaScript, jQuery, React components, and Magnolia CMS. Hosting is via AWS with multiple DNS servers. The site is well-optimized for performance and mobile devices, with good SEO practices including meta tags and structured data (JSON-LD). Cookie consent is handled by OneTrust, indicating compliance with privacy regulations. The site loads multiple scripts and assets from Atlassian's CDN, ensuring fast delivery. No technical debt or deprecated technologies were evident. Opportunities exist to enhance DNS security and add more explicit security headers.
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.
