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. 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

  2. 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"

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

ASOS operates in the competitive online fashion retail sector with a focus on international markets, supported by localized versions of the website. The business model centers on direct-to-consumer e-commerce with seasonal promotions and a broad product catalog. The company benefits from a strong digital marketing ecosystem and extensive user tracking to drive sales and customer engagement. While no direct contact information or detailed corporate data is publicly available on the site, the brand's global recognition and compliance with privacy regulations enhance its credibility. The absence of WHOIS data is likely due to privacy protection or registry technicalities rather than suspicious activity.

Security posture

The website employs HTTPS with a presumably strong SSL configuration, ensuring secure data transmission. Cookie consent and privacy policies indicate a commitment to data protection and regulatory compliance. However, the lack of explicit security headers such as Content-Security-Policy or X-Frame-Options reduces defense-in-depth. No public security policy, incident response contacts, or vulnerability disclosure programs were found, which limits transparency and readiness for security incidents. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The overall security maturity is good but could be enhanced by publishing security policies and improving header configurations.

Recommendations

  1. Implement and publish explicit security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Provide a publicly accessible security policy page detailing security practices and incident response procedures.
  3. Publish contact information for security incidents such as security@ or abuse@ email addresses.
  4. Establish and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  5. Enhance transparency around data protection officer contact details to strengthen GDPR compliance.

Technical notes

Notes

The website uses a modern technology stack including Google Tag Manager, Braze for customer engagement, New Relic for performance monitoring, and Optimizely for experimentation. Fonts are loaded efficiently with WOFF2 format. The site is optimized for desktop and mobile platforms with responsive design and accessibility considerations. Performance appears fast with preconnect hints and asynchronous script loading. No CMS was explicitly detected. Hosting provider details are not evident from the content. SEO is supported by comprehensive meta tags and Open Graph data. Overall, the technical infrastructure supports a high-quality user experience with room for security enhancements.
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.
