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 maintains a strong market position as a technology leader in customer service software, with a broad product portfolio and global reach. The company targets a diverse customer base including enterprises, SMBs, and startups across multiple industries such as retail, finance, healthcare, and telecommunications. The website's multilingual support and regional domains indicate a strategic focus on localization and market penetration. Integration with marketing and analytics tools like Marketo and Google Analytics supports data-driven growth and customer engagement. The absence of direct contact emails or phone numbers suggests a preference for managed contact channels via forms and support portals, aligning with enterprise-grade service models.

Security posture

The website exhibits a high level of security maturity with enforced HTTPS, presence of key security headers (X-Frame-Options, HSTS, X-XSS-Protection), and compliance with cookie consent regulations via OneTrust. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of explicit incident response contact information and vulnerability disclosure mechanisms represents an area for improvement. The use of modern authentication libraries and analytics scripts is balanced with privacy compliance efforts. Overall, the security posture supports business continuity and customer trust but could benefit from enhanced transparency and additional security controls.

Recommendations

  1. Implement a Content-Security-Policy (CSP) header to mitigate cross-site scripting risks.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  3. Provide explicit incident response and abuse contact information on the website.
  4. Regularly audit and update third-party scripts to minimize supply chain risks.
  5. Enhance transparency around data retention policies and user privacy controls.

Technical notes

Notes

The website is built on a modern tech stack including Next.js and React, hosted on Amazon Cloudfront CDN for optimal performance. It uses Google Tag Manager and Marketo for marketing automation and analytics, alongside OneTrust for cookie consent management. The site is mobile-optimized with responsive design and accessibility features. Performance is fast with efficient resource loading and minimal blocking scripts. The technical implementation reflects a well-maintained and scalable infrastructure suitable for enterprise-grade SaaS delivery. Opportunities exist to further improve security headers and formalize vulnerability disclosure processes.
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.
