Security report for coles.com.au

Other

Low risk. 4 critical or high findings in Security headers and GDPR outside view.

Security score

82/100

Risk levelLow

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

The website demonstrates a generally strong foundational security posture with excellent scores in email security, SSL/TLS, and network security. However, there are significant gaps in compliance and policy documentation, particularly relating to GDPR and NIS2 requirements, which pose legal and operational risks. Critical headers that mitigate common web attacks such as clickjacking and cross-site scripting are missing, exposing the site to potential exploitation. The absence of a Privacy Policy, Cookie Policy, and consent mechanisms could lead to regulatory penalties and damage to customer trust. Lack of documented information security frameworks, incident response procedures, and business continuity planning further increase organizational risk and reduce resilience to cyber incidents. DNS security is also lacking due to missing DNSSEC implementation, which could allow DNS spoofing attacks. Addressing these gaps will not only enhance security but also ensure regulatory compliance and protect business reputation. Prioritizing policy development and security controls will help safeguard assets and maintain stakeholder confidence.

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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

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.

Technical notes

Notes

Critical technical deficiencies include the absence of the X-Frame-Options header, exposing the site to clickjacking attacks, and missing the Permissions-Policy header, which restricts browser features and prevents abuse. The lack of GDPR compliance elements such as Privacy Policy, Cookie Policy, and consent mechanisms increases legal risk and undermines user privacy protection. From a regulatory standpoint, the site lacks a documented information security framework, incident response procedures, and business continuity planning, all mandatory under NIS2, severely impacting the organization's ability to manage and respond to cyber threats effectively. DNSSEC is not enabled, leaving DNS queries vulnerable to spoofing and man-in-the-middle attacks. Although SSL/TLS and email security are robust, these gaps represent critical vulnerabilities and compliance failures that must be addressed promptly.
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.
