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

Business profile

Its business model targets enterprises, SMBs, and startups, offering scalable AI-driven solutions to improve customer engagement and operational efficiency. The company maintains a strong global presence with localized websites and multi-language support. Zendesk's competitive advantages include its AI capabilities, extensive product portfolio, and certifications that enhance trust.

Security posture

Zendesk demonstrates a mature security posture with enforced HTTPS, presence of essential security headers, and adherence to recognized security frameworks such as ISO 27001 and SOC 2. The website includes a cookie consent mechanism compliant with GDPR, reflecting strong privacy practices. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the absence of some advanced headers like CSP and Referrer-Policy suggests room for improvement. Incident response contact information and vulnerability disclosure policies were not found, which could be enhanced to improve transparency and readiness. Overall, Zendesk's security measures align well with industry best practices, supporting its enterprise-grade service offerings.

Recommendations

  1. Implement Content Security Policy (CSP) headers to mitigate cross-site scripting risks.
  2. Add Referrer-Policy and Permissions-Policy headers to enhance privacy and security.
  3. Publish a clear vulnerability disclosure policy and security.txt file to improve transparency.
  4. Provide explicit incident response contact channels for security issues.
  5. Continue regular audits and updates of third-party libraries to avoid 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.
