Risk levelLow

0–100, higher is better. How it is calculated

Zendesk is a leading enterprise software company specializing in AI-powered customer service solutions. Their platform supports multiple communication channels including SMS, email, chat, and social media, serving over 200,000 customers globally. The website demonstrates a mature digital presence with modern technologies such as React and Next.js, supported by robust CDN infrastructure. Security posture is strong with HTTPS, security headers, and cookie consent mechanisms in place. However, the absence of WHOIS data is notable but does not detract from the overall trustworthiness given the brand's reputation. The site is well-optimized for performance, accessibility, and SEO, providing an excellent user experience. Strategic recommendations include enhancing security headers and expanding transparency on data retention policies.

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 in the technology sector, focusing on SaaS customer service solutions with AI integration. Their market position is strong, targeting enterprises and businesses of all sizes. The company offers a broad product suite including AI agents, ticketing, messaging, and workforce management. The website supports multiple languages and regions, indicating a global footprint. Marketing and analytics tools such as Marketo and Google Tag Manager are used for customer engagement and data-driven insights. The absence of direct contact emails or phone numbers suggests a preference for managed contact channels via forms and support portals. The brand maintains consistent and professional content, reinforcing credibility and trust.

Security posture

The website enforces HTTPS with strong SSL configuration and includes key security headers like X-Frame-Options and Strict-Transport-Security. Cookie consent is implemented via OneTrust, indicating GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the analysis. The site uses third-party scripts for analytics and marketing, which should be regularly audited to mitigate supply chain risks. Incident response and vulnerability disclosure information are not publicly available, which could be improved to enhance transparency. Overall, the security maturity is high, suitable for an enterprise-grade SaaS provider.

Recommendations

  1. Implement a comprehensive Content-Security-Policy header to mitigate XSS and data injection risks.
  2. Increase the max-age value for Strict-Transport-Security to at least 6 months or 1 year.
  3. Publish clear vulnerability disclosure and incident response policies to improve transparency and trust.
  4. Regularly audit third-party scripts and dependencies for security vulnerabilities.
  5. Provide explicit contact information for security and privacy inquiries, including a Data Protection Officer if applicable.

Technical notes

Notes

The website is built using modern JavaScript frameworks React and Next.js, ensuring a performant and responsive user experience. It leverages AWS Cloudfront CDN for fast content delivery and integrates multiple marketing and analytics tools such as Marketo, Google Tag Manager, and OneTrust for cookie management. The site is well-structured with proper meta tags for SEO and accessibility features. No CMS was explicitly detected, suggesting a custom or headless CMS approach. The technical infrastructure supports scalability and global reach, with multi-language support and optimized mobile experience. Opportunities exist to enhance security headers and formalize data retention disclosures.
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.
