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

3 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • 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

ZOLL's market positioning as a leader in healthcare technology is supported by its extensive product offerings and global reach. The business model focuses on B2B and B2C sales of medical devices and software, with revenue streams likely derived from product sales, service contracts, and software subscriptions. The company targets healthcare providers, EMS, military, and public access organizations, leveraging partnerships with related medical technology firms. The website's linkage to multiple subsidiary and partner domains indicates a robust ecosystem supporting specialized product lines. Growth indicators include comprehensive educational resources and active customer support portals. Strategic observations suggest continued investment in digital presence and compliance to maintain competitive advantage.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and domain transfer protections. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options represents potential areas of vulnerability. No explicit vulnerability disclosure or incident response contacts were found, which could hinder rapid response to security incidents. The cookie consent mechanism and privacy policy indicate awareness of privacy regulations including GDPR. No exposed sensitive data or vulnerable libraries were detected in the provided content. Overall, the security posture is good but could be enhanced by adopting additional security best practices and transparency measures.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and enforce security headers like Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web attacks.
  3. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Provide clear incident response contact information, such as a dedicated security@ or abuse@ email address.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve compliance.

Technical notes

Notes

The website uses a modern technology stack including Bootstrap for responsive design, Google Tag Manager and Analytics for tracking, and Azure DNS for domain name services. Performance is moderate with good mobile optimization and accessibility features such as screen-reader support. SEO optimization is basic with canonical and hreflang tags present but minimal meta descriptions and keywords. The site structure is clear with well-organized navigation menus and multiple language options. There is no evidence of a CMS from the provided data. Technical risks include lack of DNSSEC and missing security headers which could be addressed to improve overall security and resilience.
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.
