NIS2 and GDPR posture

Checks completed
7of 7

NIS2 Art. 21(2)

  1. (a) Risk analysis and security policies: Not visible from outside
  2. (b) Incident handling: One indicator
  3. (c) Business continuity, backups and crisis management: Not visible from outside
  4. (d) Supply chain security: Not visible from outside
  5. (e) Secure acquisition, development and maintenance, including vulnerability handling: Partly checked
  6. (f) Assessing the effectiveness of security measures: Not visible from outside
  7. (g) Cyber hygiene and security training: Not visible from outside
  8. (h) Cryptography and encryption: Partly checked
  9. (i) HR security, access control and asset management: One indicator
  10. (j) Multi-factor authentication and secured communications: Not visible from outside

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 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';…

  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

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

Business profile

11번가는 대한민국 전자상거래 시장에서 강력한 입지를 확보하고 있으며, SK 그룹의 지원을 받는 대형 플랫폼입니다. AI와 빅데이터를 활용한 맞춤형 쇼핑 솔루션과 정기 프로모션을 통해 고객 충성도를 높이고 있습니다. 주요 수익원은 판매자 수수료 및 광고 프로모션이며, 사회적 가치 창출 프로그램도 운영 중입니다. 파트너십은 SK 그룹 내 다양한 계열사와 긴밀하며, 브랜드 신뢰도와 시장 점유율 확대에 집중하고 있습니다.

Security posture

현재 웹사이트는 HTTPS를 기본으로 사용하고 있으나, DNSSEC 미적용과 보안 헤더 부재는 잠재적 위험 요소입니다. 개인정보 보호 정책과 쿠키 동의 메커니즘 부재는 규제 준수에 취약할 수 있으며, 보안 사고 대응 연락처도 공개되어 있지 않습니다. 구글 애널리틱스 및 태그 매니저 사용으로 사용자 추적이 이루어지나, 이에 대한 명확한 고지와 동의 절차가 부족합니다. 전반적으로 보안 성숙도는 중간 수준이며, 정책 및 기술적 보완이 필요합니다.

Recommendations

  1. 도메인에 DNSSEC을 활성화하여 DNS 스푸핑 공격 위험을 줄이십시오.
  2. 웹사이트에 명확한 개인정보 처리방침과 쿠키 정책을 게시하고, 사용자 동의 메커니즘을 구현하십시오.
  3. Content-Security-Policy, X-Frame-Options, X-Content-Type-Options 등의 보안 헤더를 추가하여 웹 보안을 강화하십시오.
  4. 보안 사고 대응을 위한 연락처(예: security@ 도메인 이메일)를 공개하여 신뢰도를 높이십시오.
  5. 서드파티 스크립트 및 라이브러리의 정기적인 보안 점검과 업데이트를 수행하십시오.

Technical notes

Notes

웹사이트는 jQuery 3.1.1, Swiper.js, iScroll5 등 비교적 최신의 프론트엔드 라이브러리를 사용하며, Google Analytics 및 Tag Manager를 통한 데이터 분석과 마케팅 자동화를 구현하고 있습니다. AWS 기반 DNS 네임서버를 사용하여 안정적인 인프라를 운영 중입니다. 모바일 최적화가 잘 되어 있으며, 접근성은 기본 수준입니다. SEO 메타 태그가 적절히 설정되어 있으나, 보안 헤더 부재와 DNSSEC 미적용은 기술적 부채로 작용할 수 있습니다. 전반적으로 기술 인프라는 견고하나 보안 및 개인정보 보호 관련 현대화가 필요합니다.
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.
