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

COS is a large, family-owned Australian supplier specializing in office products, furniture, kitchen, bathroom, paper, and educational supplies. Positioned as Australia's largest family-owned supplier in this sector, COS serves a broad target audience including businesses and educational institutions. Their business model focuses on B2B and B2C e-commerce retail with additional services such as print management and promotional products. The website reflects a professional and consistent brand image with comprehensive content and active customer engagement channels including live chat and social media. Technically, the website is built on a modern Angular framework with integration of multiple analytics and marketing tools such as HubSpot, Google Tag Manager, Hotjar, and Facebook Pixel. The infrastructure leverages AWS CloudFront CDN for hosting and content delivery, ensuring moderate performance and good mobile optimization. Accessibility features are basic but functional, and SEO practices are well implemented. From a security perspective, the site enforces HTTPS with strong SSL configuration and employs standard security headers to protect against common web vulnerabilities. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a public incident response policy and vulnerability disclosure program suggests room for improvement in security transparency and readiness. Overall, COS presents a secure, trustworthy, and professionally managed online presence with a strong market position in the Australian office supplies sector. Strategic recommendations include enhancing security policies, improving accessibility compliance, and formalizing vulnerability disclosure mechanisms to further strengthen trust and compliance.

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

8 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.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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"

    • 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';…

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

COS holds a dominant position as Australia's largest family-owned supplier in the office products and related sectors. Their competitive advantage lies in their extensive product range, family-owned business reputation, and comprehensive service offerings including print management and promotional products. The business model is primarily e-commerce focused, targeting Australian businesses and educational institutions. Revenue streams likely include product sales, print services, and promotional product offerings. The company maintains a partnership ecosystem evident from related domains and integrates multiple marketing and analytics platforms to support growth and customer engagement. Strategic observations highlight a mature digital presence with opportunities to enhance security transparency and accessibility.

Security posture

COS demonstrates a mature security posture with enforced HTTPS, robust SSL configuration, and implementation of key security headers such as Content-Security-Policy and X-Frame-Options. The website avoids exposing sensitive data and uses secure forms for data collection. However, the lack of a publicly available incident response policy and vulnerability disclosure program indicates gaps in security governance and transparency. Compliance with GDPR is implied through privacy and cookie policies, but explicit data retention policies are not detailed. The presence of multiple third-party scripts necessitates ongoing vulnerability management. Overall, the security maturity is good but could be improved by formalizing incident response and disclosure practices.

Recommendations

  1. Publish a clear incident response policy with dedicated contact channels for security issues.
  2. Implement and publicize a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  3. Enhance website accessibility to meet recognized standards such as WCAG 2.1.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Expand privacy disclosures to include detailed data retention and processing policies.

Performance is moderate, with opportunities to optimize load times and accessibility 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.
