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. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

Tableau operates in the technology sector, focusing on analytics and business intelligence solutions. Its business model centers on SaaS offerings and enterprise analytics platforms, targeting a broad audience including analysts, IT leaders, business leaders, and developers. The company benefits from its parent Salesforce's ecosystem, enhancing its market position and reach. The website highlights key services such as Tableau Next, Tableau Cloud, and Tableau Public, supported by a large community and customer base. Strategic partnerships and certifications like Gartner Magic Quadrant leadership reinforce its competitive advantage. The content and navigation cater to prospects and customers, emphasizing product innovation and customer success stories.

Security posture

The website exhibits a strong security posture with enforced HTTPS, comprehensive security headers, and no visible exposure of sensitive data. The use of OneTrust for cookie consent indicates compliance with GDPR and other privacy regulations. However, the absence of a dedicated security policy page and incident response contact details suggests room for improvement in transparency and readiness. No vulnerable or outdated libraries were detected in the scripts. The site follows best practices in securing user interactions and data collection, but publishing a vulnerability disclosure policy and security.txt would enhance trust and incident management capabilities.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure program or security.txt file.
  4. Enhance accessibility features to meet higher standards for all users.
  5. Regularly review and audit third-party scripts and tracking tools for security risks.

Technical notes

Notes

The website is built on a modern technology stack including Salesforce Experience Cloud, JavaScript frameworks, and various third-party integrations for analytics, consent management, and performance monitoring. It uses Akamai CDN for hosting and fast content delivery. The site is mobile-optimized with responsive design and accessibility considerations. SEO is well implemented with proper meta tags, Open Graph data, and structured JSON-LD schema for organization and product information. Performance monitoring via Boomerang and A/B testing with Optimizely indicate a mature approach to continuous improvement. Technical risks are minimal, but ongoing maintenance of third-party dependencies is advised to mitigate potential vulnerabilities.
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.
