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

OK캐쉬백 is a well-established South Korean cashback and loyalty rewards platform operated by SK PLANET, a large technology and retail company. The website offers users the ability to accumulate and redeem points through a wide network of domestic shopping partners, events, and travel affiliates. The platform targets Korean consumers interested in maximizing value from their shopping activities through affiliate marketing and promotional events. The business model is based on partnerships with major retailers and service providers, leveraging affiliate commissions and user engagement to drive revenue. Technically, the website employs modern JavaScript libraries such as jQuery and Swiper for UI components and interactivity. The site is mobile-optimized and includes accessibility considerations, providing a good user experience. The domain is mature, registered since 1999, and hosted under a reputable registrar. However, some security enhancements such as DNSSEC and HTTP security headers are missing, which could be improved to strengthen the security posture. From a security perspective, the site enforces HTTPS and protects domain transfer, but lacks visible security policies and incident response information. Privacy compliance is partially addressed with a privacy policy and terms of service, but no cookie consent mechanism is present. No vulnerabilities or malicious content were detected. Overall, the site demonstrates a solid security baseline but could benefit from enhanced transparency and technical security controls. The overall risk assessment is low, with the site appearing trustworthy and professionally managed. Strategic recommendations include enabling DNSSEC, implementing security headers, adding cookie consent, and publishing explicit security and incident response policies to improve compliance and user trust.

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

7 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, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

OK캐쉬백 holds a strong market position in South Korea's loyalty and cashback sector, backed by SK PLANET. Its competitive advantage lies in its extensive affiliate network with major domestic retailers and integrated event promotions. The business model focuses on affiliate marketing revenue and user engagement through point accumulation and redemption. Target customers are Korean consumers who shop online and offline and seek cashback benefits. Growth indicators include continuous addition of partners and promotional events. The partnership ecosystem includes major retailers like Lotte, Homeplus, and Gmarket, enhancing market reach. Operationally, the company maintains a professional web presence with clear branding and user-centric features, supporting sustained market relevance.

Security posture

The website exhibits a moderate security maturity level with HTTPS enforced and domain transfer protection. However, the absence of DNSSEC and HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options indicates room for improvement. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Privacy policies are present but lack cookie consent mechanisms and detailed incident response information. The site does not publish a vulnerability disclosure or security.txt file. Overall, the security posture is adequate for a consumer-facing platform but would benefit from enhanced technical controls and transparency to meet higher compliance standards such as GDPR and NIS2.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement HTTP security headers including Content Security Policy, HSTS, and X-Frame-Options.
  3. Add a cookie consent banner to comply with privacy regulations and improve user transparency.
  4. Publish explicit security policies and incident response contact information on the website.
  5. Consider establishing a vulnerability disclosure program or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website uses a traditional web stack with jQuery 3.7.1 and Swiper.js for UI components, indicating a mature but somewhat dated technology approach. The site is mobile-optimized and includes accessibility features, contributing to good user experience. Performance is moderate with no major issues detected. The domain is hosted under Gabia, Inc., a reputable registrar. There is no evidence of a CMS or modern frontend frameworks like React or Angular. The site could benefit from modernization to improve maintainability and performance. Technical risks include missing DNSSEC and security headers, which could expose the site to DNS spoofing and clickjacking attacks.
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.
