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. 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"

  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, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Zendesk operates a SaaS business model targeting businesses seeking comprehensive customer service solutions. Their market position is strong, supported by a large customer base and global reach with localized websites. Key services include AI agents, ticketing, messaging, voice, and workforce management. The company maintains a robust partnership ecosystem including the Zendesk Foundation. Their content and navigation are well structured, supporting enterprise and SMB segments across various industries such as technology, retail, financial services, healthcare, and telecommunications.

Security posture

Zendesk exhibits a high level of security maturity with enforced HTTPS, presence of key security headers, and comprehensive privacy and security policies. No exposed sensitive data or vulnerable libraries were detected in the website content. The company holds recognized certifications such as SOC 2 and ISO 27001, indicating adherence to industry security standards. However, there is room for improvement by adding Content-Security-Policy and other advanced headers. Incident response contact information was not explicitly found, which could be enhanced for transparency.

Recommendations

  1. Implement Content-Security-Policy header to mitigate XSS and data injection risks.
  2. Add X-Content-Type-Options and Referrer-Policy headers for improved security.
  3. Publish explicit incident response and vulnerability disclosure contacts or pages.
  4. Regularly review and audit third-party scripts and analytics for security compliance.
  5. Enhance transparency by providing direct contact details for security and privacy inquiries.

Notes

The website uses a modern tech stack including React and Next.js frameworks, supported by Amazon Cloudfront CDN for fast content delivery. It integrates Google Tag Manager, Segment Analytics, and Adobe Web SDK for marketing and analytics purposes, with OneTrust managing cookie consent. The site is mobile optimized and accessible, with strong SEO practices evident from meta tags and structured navigation. Performance is fast with deferred and async script loading. No CMS was explicitly detected, suggesting a custom or headless architecture. Overall, the technical infrastructure is robust and scalable, suitable for enterprise-grade operations.
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.
