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 customer service software with AI integration. Their business model is subscription-based SaaS, targeting a broad market including enterprise, SMBs, and startups. The company maintains a strong market position with a large customer base and recognized certifications like ISO 27001. Their ecosystem includes partnerships and a foundation for social impact. Zendesk's offerings cover ticketing, messaging, voice, quality assurance, and workforce management, enabling comprehensive customer experience management. The multilingual website and global domains indicate a worldwide reach. Their marketing leverages analytics and consent-based tracking, reflecting a data-driven approach. Strategic observations include continuous AI innovation and strong brand consistency, supporting growth and competitive advantage.

Security posture

Zendesk exhibits a high level of security maturity with enforced HTTPS, multiple security headers (X-Frame-Options, HSTS, X-XSS-Protection), and ISO 27001 certification. Privacy policies and cookie consent mechanisms are comprehensive and GDPR compliant. No exposed sensitive data or vulnerable libraries were detected in the website content. However, the absence of a security.txt file or explicit vulnerability disclosure program is noted as an area for improvement. Incident response contact information is not publicly visible, which could be enhanced for transparency. Overall, Zendesk maintains a strong security culture appropriate for an enterprise SaaS provider, minimizing risks related to data breaches and compliance violations.

Recommendations

  1. Implement a Content Security Policy (CSP) header to mitigate XSS and data injection risks.
  2. Enhance HSTS header by including subdomains and increasing max-age for stronger HTTPS enforcement.
  3. Publish a security.txt file to facilitate responsible vulnerability disclosure and improve transparency.
  4. Provide clear incident response contact channels on the website for security researchers and customers.
  5. Continue monitoring and updating third-party libraries to avoid vulnerabilities and maintain compliance.

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.
