Zendesk is a leading global provider of AI-driven customer service software solutions, trusted by over 200,000 customers. The company offers a comprehensive suite of products including AI agents, ticketing systems, messaging, live chat, voice, and workforce management, targeting businesses of all sizes from startups to large enterprises. The website is professionally designed, multilingual, and optimized for performance and accessibility, reflecting a mature digital presence. Technically, Zendesk employs modern web frameworks such as Next.js, integrates with major marketing and analytics platforms like Google Tag Manager and Marketo, and uses AWS Cloudfront for hosting and CDN services. Security is robust with HTTPS enforced, appropriate security headers, and cookie consent mechanisms in place. However, explicit incident response and vulnerability disclosure information are not publicly available, which could be improved.

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

4 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 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 focused on customer service and support software enhanced with AI capabilities. Its market positioning is strong, serving a broad customer base including enterprises, SMBs, and startups across multiple industries such as technology, retail, finance, healthcare, and telecommunications. The company maintains a global footprint with localized websites and language support. Zendesk's competitive advantages include its AI-driven product suite, extensive integrations, and a well-established brand. The company leverages partnerships and events like the Zendesk AI Summit to engage its ecosystem. Revenue streams are primarily subscription-based. The website content and structure indicate a focus on customer satisfaction, innovation, and trust-building.

Security posture

Zendesk's security posture is solid, with enforced HTTPS, presence of key security headers (X-Frame-Options, HSTS, X-XSS-Protection), and cookie consent aligned with GDPR requirements. The site avoids exposing sensitive data and uses modern authentication libraries. However, the absence of publicly available incident response contacts and vulnerability disclosure policies represents a compliance gap. No vulnerable libraries or security issues were detected in the analyzed content. The company demonstrates a mature security culture but could enhance transparency and readiness by publishing detailed security policies and response procedures.

Recommendations

  1. Publish explicit incident response and security contact information on the website.
  2. Implement and publicize a vulnerability disclosure policy and security.txt file.
  3. Highlight security certifications and compliance frameworks (e.g., ISO 27001, SOC 2) to enhance trust.
  4. Conduct regular audits of third-party scripts and dependencies to mitigate supply chain risks.
  5. Enhance accessibility features to meet or exceed WCAG 2.1 AA standards.

Technical notes

Notes

The website is built on a modern React-based framework (Next.js) with server-side rendering for performance. It uses AWS Cloudfront as CDN and hosting provider, ensuring fast global delivery. Integration with marketing and analytics tools like Marketo and Google Tag Manager is evident, supporting data-driven marketing. The site is mobile-optimized and accessible, with structured navigation and multilingual support. No technical debt or deprecated technologies were detected. The use of security headers and HTTPS indicates good security hygiene. Opportunities exist to improve transparency around security policies and incident response.
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.
