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

3 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  2. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

  • Security headers: did not complete in this scan.
  • 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

Whois Corp. holds a dominant position in the South Korean domain and business IT solutions market, leveraging its long-standing domain registration history since 1998. The company’s business model revolves around providing integrated domain and hosting services, complemented by email, groupware, and marketing solutions. Its client base includes large enterprises, indicating strong market trust and brand recognition. The company maintains a broad partnership ecosystem with multiple service subdomains and platforms under its control. Revenue streams likely include domain registration fees, hosting subscriptions, email services, SSL certificate sales, and marketing services. The company demonstrates growth through diversified offerings and strategic partnerships. Its certifications and customer satisfaction ratings further reinforce its competitive advantage and operational excellence.

Security posture

The website exhibits a mature security posture with mandatory HTTPS, domain status protections like clientTransferProhibited, and ISMS certification indicating adherence to recognized security standards. However, the absence of security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options represents an area for improvement to mitigate common web vulnerabilities. The lack of explicit incident response contact information and vulnerability disclosure policies suggests limited transparency in security incident handling. Privacy compliance is partial, with a comprehensive privacy policy but no visible cookie consent mechanism, which may impact GDPR compliance. No vulnerabilities or exposed sensitive data were detected in the analysis. Overall, the security posture is strong but could benefit from enhanced transparency and technical controls.

Recommendations

  1. Implement security headers including CSP, HSTS, and X-Frame-Options to strengthen web security.
  2. Publish clear incident response and vulnerability disclosure contact information to improve transparency and trust.
  3. Introduce a cookie consent banner or mechanism to enhance privacy compliance and user awareness.
  4. Regularly audit third-party scripts and analytics tools to ensure no vulnerable libraries are in use.
  5. Enhance data protection officer visibility and GDPR compliance documentation.

Technical notes

Notes

The website uses a modern technology stack including jQuery, Google Analytics, Google Tag Manager, Owl Carousel, and Slider Pro for UI components and analytics. The site is self-hosted by Whois Corp., ensuring control over hosting infrastructure. Performance is moderate with good mobile optimization and accessibility features. SEO is well addressed with proper meta tags and Open Graph data. The site structure is clear with multiple service offerings accessible via well-organized navigation menus. There is some technical debt in the form of missing security headers and lack of explicit privacy consent mechanisms. Overall, the technical implementation supports a professional and scalable online presence with opportunities for security and privacy enhancements.
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.
