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

SK플래닛 주식회사는 대한민국에 기반을 둔 선도적인 데이터 및 기술 기업으로, 데이터 인프라를 바탕으로 마케팅 플랫폼과 비즈니스 솔루션을 제공하고 있습니다. 주요 서비스로는 OK CASHBAG, Syrup, AI 기반 서비스, IoT, 미디어 스트리밍, 그리고 통신 부가 서비스 등이 포함되어 있으며, 국내 시장에서 강력한 입지를 확보하고 있습니다. 웹사이트는 한국어를 기본으로 하며, 기업 고객과 일반 소비자를 대상으로 한 다양한 디지털 마케팅 및 비즈니스 솔루션을 제공합니다. 기술적으로는 최신 jQuery, Swiper, Slick Carousel과 같은 라이브러리를 활용하며, Google Analytics와 Google Tag Manager를 통한 사용자 분석을 수행하고 있습니다. 보안 측면에서는 HTTPS 사용이 암시되나, 명확한 보안 헤더 설정과 쿠키 동의 메커니즘은 부족한 상태입니다. WHOIS 데이터가 조회되지 않아 도메인 등록 정보의 신뢰성에 의문이 있으나, 사이트의 전문성과 공식 주소, 인증 마크 등은 신뢰도를 보완합니다. 전반적으로 기술적 완성도와 비즈니스 신뢰성은 높으나, 개인정보 보호 및 보안 정책 강화가 권장됩니다.

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. 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 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';…

  3. 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

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.

Business context

Business profile

SK플래닛은 데이터 기반 마케팅과 비즈니스 솔루션 분야에서 경쟁 우위를 가진 대형 기술 기업입니다. 주요 수익원은 디지털 마케팅 플랫폼과 IoT, AI, 미디어 스트리밍 서비스에서 발생하며, OK CASHBAG과 Syrup 같은 자체 브랜드를 통해 소비자와 직접 연결됩니다. 파트너십으로는 SK 그룹 내 윤리경영 사이트와 교육 아카데미, 기술 블로그 등이 있으며, 이는 기업의 생태계 확장과 브랜드 신뢰도 향상에 기여합니다. 성장 지표로는 최신 보도자료와 채용 공고가 활발히 업데이트되고 있어 지속적인 사업 확장이 예상됩니다. 시장 내 입지는 국내 데이터 및 디지털 마케팅 분야에서 선도적이며, 기술 혁신과 고객 맞춤형 서비스 제공에 집중하고 있습니다.

Security posture

현재 웹사이트는 HTTPS를 사용하며, Google Analytics 및 Tag Manager를 통한 트래픽 분석이 구현되어 있습니다. 그러나 보안 헤더 부재, 쿠키 동의 미비, 그리고 명확한 보안 정책 부재는 보안 성숙도에 부정적 영향을 미칩니다. WHOIS 정보 부재는 도메인 신뢰성에 의문을 제기하며, 이는 피싱이나 도메인 탈취 위험 가능성을 내포합니다. 개인정보 보호 및 GDPR 준수 관련 정책은 기본 수준에 머물러 있으며, 보안 사고 대응 체계 및 취약점 공개 정책은 확인되지 않습니다. 전반적으로 보안 강화와 정책 명확화가 필요하며, 특히 도메인 등록 정보의 투명성 확보가 중요합니다.

Recommendations

  1. 도메인 WHOIS 정보를 명확히 공개하여 도메인 신뢰성을 확보할 것
  2. 웹사이트에 보안 헤더(Content-Security-Policy, X-Frame-Options 등)를 추가하여 보안 강화
  3. 쿠키 정책 및 동의 배너를 구현하여 GDPR 및 개인정보 보호 규정을 준수할 것
  4. 취약점 공개 정책 및 보안 사고 대응 연락처를 웹사이트에 명시할 것
  5. 정기적인 보안 점검과 최신 라이브러리 업데이트를 통해 보안 취약점 최소화

Technical notes

Notes

웹사이트는 jQuery, Swiper, Slick Carousel 등 다양한 자바스크립트 라이브러리를 활용하여 사용자 경험을 향상시키고 있습니다. Google Analytics와 Tag Manager를 통한 데이터 수집이 이루어지고 있으나, 다중 jQuery 버전 사용은 기술 부채 가능성을 시사합니다. 웹사이트는 반응형 디자인과 접근성 인증을 갖추어 모바일 및 장애인 접근성 측면에서 우수한 편입니다. SEO 최적화도 적절히 구현되어 있으며, 빠른 로딩 속도를 위해 외부 스크립트 비동기 로딩을 사용합니다. 다만, CMS 사용 여부는 확인되지 않으며, 호스팅 제공자 정보도 불명확합니다. 전반적으로 기술 인프라는 현대적이나 일부 코드 정리 및 보안 강화가 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.
