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

Business context

Business profile

NHN operates primarily in the technology sector with a focus on gaming, payment processing, commerce, and technology platforms. Its business model leverages diversified revenue streams from consumer-facing gaming products and B2B payment and commerce services. The company targets a broad audience including gamers, businesses, and general consumers. NHN's extensive subsidiary network and global presence indicate strategic partnerships and market expansion. The company actively communicates through press releases and career opportunities, signaling growth and innovation. NHN's competitive advantage lies in its integrated service offerings and established brand in the Asian market, particularly South Korea and Japan.

Security posture

NHN's security posture is generally strong with HTTPS enforced and domain registration protections in place. However, the absence of DNSSEC and lack of published security policies or incident response contacts represent gaps in transparency and defense-in-depth. No critical vulnerabilities or exposed sensitive data were detected in the website content. The lack of cookie consent mechanisms may pose compliance risks under GDPR and similar regulations. Overall, NHN appears security-conscious but could improve by adopting additional security best practices and enhancing user privacy controls.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish a comprehensive security policy and incident response contact information on the website.
  3. Implement a cookie consent banner and detailed cookie policy to comply with GDPR and other privacy laws.
  4. Add security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options to enhance web security.
  5. Provide clear and accessible contact information including emails and phone numbers for customer and security inquiries.

Technical notes

Notes

The website is built on a modern React-based framework (Next.js), ensuring good performance and SEO optimization. It uses external fonts and CDN resources for efficient loading. The hosting infrastructure includes Akamai DNS services, indicating reliable global content delivery. The site is mobile optimized and accessible with clear navigation and multilingual support. No major technical debt or outdated technologies were detected. However, the absence of some security headers and privacy compliance features suggests areas for technical enhancement to align with best practices.
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.
