Risk levelLow

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

International SOS is a globally recognized leader in international health and security risk management, providing comprehensive services to protect business travellers and international assignees from health and security threats worldwide. The company offers tailored solutions including travel risk management aligned with ISO 31030, executive protection, and a proprietary assistance app. Their market position as a pioneer and their 40 years of operational history underscore their expertise and reliability in this niche. Technically, the website is built on modern web technologies such as React and JavaScript, with a responsive design optimized for mobile devices. The site integrates multiple analytics and marketing tools, including Google Tag Manager, Microsoft Clarity, and LinkedIn Insight, reflecting a mature digital marketing strategy. Performance is moderate with good SEO and accessibility features. From a security perspective, the site enforces HTTPS, implements key security headers, and uses secure forms with consent mechanisms. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of a public vulnerability disclosure or security.txt file and incident response contact details suggests room for improvement in transparency and security communication. Overall, the website presents a professional, trustworthy, and well-maintained digital presence. The lack of WHOIS data reduces some trustworthiness but is likely due to privacy protection or domain management practices. Strategic recommendations include publishing vulnerability disclosure information, enhancing incident response transparency, and maintaining rigorous security practices to uphold their market leadership.

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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  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

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

International SOS operates in the healthcare and security sectors, targeting corporate clients with international travel and security needs. Their business model focuses on providing risk management services, training, and technology solutions to mitigate health and security risks for global travellers. The company leverages certifications like ISO 31030 to differentiate itself and maintain compliance standards. Their global presence is supported by multilingual websites and localized services. Partnerships and service portals such as eShop and subscriber login enhance client engagement. The company demonstrates strong branding consistency and trust indicators, positioning itself as a market leader with a large enterprise footprint.

Security posture

The website exhibits a mature security posture with HTTPS enforcement and comprehensive security headers. The use of secure forms and cookie consent mechanisms aligns with privacy regulations such as GDPR. No exposed sensitive information or vulnerable libraries were identified. However, the absence of a public vulnerability disclosure policy and incident response contact information limits transparency and may delay response to security incidents. The integration of multiple third-party analytics and marketing tools introduces a moderate level of user tracking, which is managed with consent banners. Overall, the security maturity is high but could benefit from enhanced disclosure and incident readiness.

Recommendations

  1. Publish a publicly accessible vulnerability disclosure or security.txt file to improve transparency and facilitate responsible reporting.
  2. Provide clear incident response contact information on the website to enhance trust and readiness.
  3. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure compliance.
  4. Enhance documentation of security certifications and policies to reinforce market leadership and client confidence.
  5. Maintain continuous monitoring and update of security headers and SSL configurations to uphold best practices.

Technical notes

Notes

The website is built using React, leveraging modern JavaScript and CSS for a responsive and accessible user experience. It integrates multiple analytics and marketing platforms, including Google Tag Manager, Microsoft Clarity, and LinkedIn Insight, indicating a sophisticated digital marketing infrastructure. The site uses CDN-hosted assets for performance optimization. While performance is moderate, the site is well-structured with proper meta tags and SEO optimizations. Accessibility features such as skip links and ARIA roles are implemented, enhancing usability. There is no detected CMS, suggesting a custom or proprietary platform. Hosting details are not explicitly identified but likely involve enterprise-grade providers.
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.
