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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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"

  3. 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"

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 solutions enhanced by artificial intelligence. Its market position is strong as a recognized leader in the technology sector, serving diverse industries including retail, finance, healthcare, and telecommunications. The company emphasizes trust and security, demonstrated by dedicated trust center resources and privacy policies. The website's extensive product and solution offerings, along with professional services and partner ecosystems, indicate a mature and scalable business operation. Multi-language and regional site versions support global reach and localization strategies.

Security posture

The website exhibits a mature security posture with enforced HTTPS, presence of key security headers (X-Frame-Options, HSTS, X-XSS-Protection), and integration of cookie consent management via OneTrust. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the absence of explicit incident response contacts and vulnerability disclosure policies represents an area for improvement. The use of third-party marketing and analytics scripts is managed with consent mechanisms, reducing privacy risks. Overall, the security practices align with enterprise standards but could be further strengthened by publishing detailed security policies and incident response procedures.

Recommendations

  1. Publish explicit incident response contact details and a vulnerability disclosure policy to enhance transparency and security readiness.
  2. Implement and publish a security.txt file to facilitate responsible vulnerability reporting.
  3. Enhance security headers by adding Content-Security-Policy and Referrer-Policy for improved protection.
  4. Regularly audit and update third-party scripts to mitigate potential supply chain risks.
  5. Consider publishing data protection officer contact information to improve GDPR compliance visibility.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, ensuring server-side rendering and good SEO. Hosting on Amazon CloudFront provides reliable global content delivery. Integration with marketing automation (Marketo), analytics (Google Tag Manager), and consent management (OneTrust) demonstrates a mature digital marketing infrastructure. The site is optimized for mobile devices and accessibility, with comprehensive meta tags and Open Graph data supporting social sharing. Performance is fast with preconnect and preload hints. Technical risks are minimal, though continuous monitoring of third-party dependencies is advised to maintain security and performance.
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.
