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

Eleven Street Co.,Ltd. operates 11st.co.kr, a leading South Korean e-commerce platform established in 2007. The website serves a broad Korean consumer base offering fast delivery services, overseas shopping options including Amazon integration, and fresh food same-day shipping. The company holds a strong market position as a major online marketplace in Korea. Technically, the website employs modern analytics and advertising technologies such as Google Analytics, Google Tag Manager, and Kakao Pixel, hosted on AWS infrastructure. The site is accessible over HTTPS with asynchronous script loading, but lacks visible security headers and explicit privacy or cookie policies in the provided snapshot. Security posture is generally good but could be improved with enhanced headers and clearer privacy compliance. Business credibility is high given the consistent WHOIS data and domain age. Overall, the site is functional and professional but would benefit from improved privacy transparency and security best practices.

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. 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 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. 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.

Business context

Business profile

The company is a large-scale e-commerce entity targeting Korean consumers with a diversified service offering including rapid delivery and international shopping. Its business model is based on an online marketplace platform, leveraging partnerships such as Gabia for domain registration. The company’s long domain history and consistent registration data indicate stable operations. The presence of multiple tracking and advertising technologies suggests a mature marketing ecosystem. However, the lack of visible privacy and security policies on the main page may pose compliance risks. The company’s growth and market presence are supported by its comprehensive service portfolio and technological adoption.

Security posture

The website enforces HTTPS and uses reputable third-party analytics and advertising services, which is positive for security and performance. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces defense-in-depth. No forms or input fields were detected in the snapshot, limiting exposure to input-based vulnerabilities. The lack of published security or incident response policies and contact channels indicates room for improvement in transparency and readiness. Overall, the security posture is moderate with good foundational elements but missing some best practices and compliance documentation.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve GDPR and local compliance.
  2. Add security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  3. Provide clear security incident response contact information and policies on the website.
  4. Improve mobile optimization and accessibility features to enhance user experience and compliance.
  5. Regularly audit third-party scripts and tracking technologies to minimize privacy risks and improve transparency.

Technical notes

Notes

The website uses a modern JavaScript stack with jQuery and custom scripts, supported by AWS-hosted DNS infrastructure. Analytics and marketing tools are integrated via Google Tag Manager and Kakao Pixel, indicating a mature digital marketing approach. Performance is moderate with asynchronous script loading but could be improved with enhanced mobile responsiveness and accessibility. No CMS or framework was explicitly detected, suggesting a custom or proprietary platform. The domain is well-established and hosted securely over HTTPS. Technical debt appears low but the lack of security headers and privacy documentation are notable gaps.
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.
