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

5 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"

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  3. 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
    • 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 in the technology sector, focusing on SaaS customer service solutions enhanced by AI capabilities. Their market position is strong, targeting large enterprises and SMBs with a broad product portfolio including AI Agents, Copilot, ticketing systems, messaging, and workforce management. The company emphasizes trust and security, offering resources like a trust center and privacy protection pages. Their global reach is evident from multiple localized websites and language options. The business model is subscription-based SaaS, with revenue streams from software licenses and professional services. Partnerships and integrations are highlighted, supporting ecosystem growth. The website content and structure reflect a mature, enterprise-grade operation with consistent branding and high-quality content.

Security posture

The website exhibits a solid security posture with HTTPS enabled and key security headers such as X-Frame-Options, Strict-Transport-Security, and X-XSS-Protection configured. Cookie consent is managed via OneTrust, indicating GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the analysis. However, the absence of a public incident response contact or vulnerability disclosure page suggests room for improvement in transparency and security communication. The use of Cloudflare DNS and modern authentication libraries (MSAL) further strengthens security. Overall, Zendesk demonstrates good security hygiene appropriate for an enterprise SaaS provider.

Recommendations

  1. Publish a dedicated incident response and vulnerability disclosure page to improve transparency and trust.
  2. Implement and publicize a security.txt file to facilitate responsible vulnerability reporting.
  3. Enhance security headers by adding Content-Security-Policy to mitigate XSS and data injection risks.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.
  5. Clarify data retention policies and make them easily accessible to users to strengthen privacy compliance.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, ensuring server-side rendering and good SEO performance. Hosting is managed via Cloudflare, providing CDN and DNS services that enhance security and performance. The site includes integrations with Google Tag Manager, Adobe Web SDK, and OneTrust for analytics and compliance. Mobile optimization and accessibility are well addressed, with responsive design and skip-to-content links. Performance is moderate, likely due to extensive scripts and third-party integrations. The technical stack is robust and suitable for a global enterprise SaaS platform, though continuous monitoring of third-party components is advised to mitigate risks.
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.
