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

ASOS is a leading online fashion and beauty retailer targeting primarily young, fashion-conscious consumers. The website offers a comprehensive range of products including clothing, shoes, accessories, and face and body products, supported by curated collections and promotional sales. The platform demonstrates a mature e-commerce business model with a strong market position internationally. Technically, the website employs modern JavaScript frameworks and integrates advanced analytics and marketing tools such as Google Tag Manager, New Relic, and OneTrust for privacy compliance. The site is well-optimized for mobile and accessibility, providing a professional user experience with clear navigation and rich content. Security-wise, the site enforces HTTPS and cookie consent mechanisms but lacks visible security headers and explicit security policies or incident response information. WHOIS data is unavailable or privacy protected, which is typical for large brands to prevent abuse. Overall, the website is legitimate, professional, and secure with room for improvement in security transparency and policy disclosures.

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

1 finding rated critical or high. Fix these first.

  1. 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

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

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

  • Security headers: did not complete in this scan.
  • 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

ASOS operates in the competitive online fashion retail sector, leveraging a broad product catalog and strong brand recognition. Its business model focuses on direct-to-consumer e-commerce with extensive use of digital marketing and analytics to drive sales and customer engagement. The company targets a global audience with localized content and multiple language/country versions. Partnerships with major brands and its own ASOS brands enhance its market offering. The absence of direct contact emails or phone numbers on the homepage suggests a focus on digital self-service and customer care portals. The company shows strong digital maturity but could benefit from enhanced security communication and incident response readiness to further build customer trust.

Security posture

The website demonstrates a solid baseline security posture with HTTPS enforced and cookie consent implemented, indicating GDPR compliance. However, the absence of key security headers such as Content-Security-Policy and lack of published security or incident response policies represent gaps in transparency and defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of reputable analytics and marketing services is balanced with privacy controls. The WHOIS privacy protection is justified but limits external verification of domain ownership. Overall, the security posture is good but could be improved by publishing security policies, incident response contacts, and implementing additional HTTP security headers.

Recommendations

  1. Implement and publish a dedicated security policy and incident response page to improve transparency and customer trust.
  2. Add HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  3. Publish a vulnerability disclosure or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance contact information availability for security and privacy concerns, including dedicated security or abuse email addresses.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerable components are included and maintain privacy compliance.

Technical notes

Notes

The website uses a modern JavaScript-based front end with asynchronous loading of scripts and integration of multiple third-party services including Google Tag Manager, New Relic for performance monitoring, and OneTrust for cookie consent management. The site is optimized for desktop and mobile with responsive design and accessibility features. Performance is moderate with preconnect hints and font optimizations. The absence of a detected CMS suggests a custom or proprietary platform. Hosting details are not explicitly found but likely use a robust CDN and cloud infrastructure given the scale. Technical risks include reliance on multiple third-party scripts which require ongoing security and privacy management.
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.
