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

HD Hyundai Heavy Industries Co., Ltd. operates the HD Arts Center website, a regional cultural hub in Ulsan, South Korea, providing ticketing and event management services for performances, exhibitions, movies, and lectures. The website targets a general audience interested in arts and culture, offering a comprehensive range of services including venue rental and membership programs. The business model centers on event ticket sales and cultural engagement, positioning the company as a key player in the local arts and entertainment sector. Technically, the website employs a custom CMS with modern JavaScript libraries such as jQuery, Slick Slider, and the Kakao SDK, supporting both web and mobile platforms including a Cordova-based app. The site demonstrates good mobile optimization and basic accessibility features, with moderate performance and SEO optimization. Hosting and domain management are handled by Gabia, a reputable Korean registrar. From a security perspective, the site uses HTTPS and includes several security headers like Content-Security-Policy, though the CSP allows unsafe inline scripts and eval, which is a potential risk. DNSSEC is not implemented, and no dedicated security or incident response policies are visible. Privacy and cookie policies are present, but GDPR compliance is limited. Overall, the security posture is adequate but could be improved with stronger CSP, DNSSEC, and incident response disclosures. The domain WHOIS data is consistent with the business identity, showing transparent registration without privacy protection, appropriate for this type of cultural institution. The domain is relatively new but aligns with the event dates presented. No suspicious patterns were detected. The website content is safe for general audiences with no adult or questionable material. Strategic recommendations include enhancing security headers, implementing DNSSEC, and publishing incident response contacts to strengthen trust and compliance.

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

11 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  2. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      No Name Servers Found

      Unable to find name servers for domain

      What to do: Configure proper name servers for the domain

  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

    • 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.

Business context

Business profile

The HD Arts Center is positioned as a large regional cultural institution under HD Hyundai Heavy Industries Co., Ltd., focusing on arts and entertainment in Ulsan, South Korea. Its competitive advantage lies in its comprehensive event offerings across multiple cultural domains and integration with digital ticketing and membership services. Revenue streams likely include ticket sales, venue rentals, and memberships. The target customer segments are local residents and visitors interested in cultural events. Growth indicators include a robust event calendar and mobile app presence. The partnership ecosystem includes regional cultural centers and a reputable domain registrar. Operationally, the company demonstrates a mature digital presence with room for security and compliance enhancements.

Security posture

The website exhibits a moderate security maturity level with HTTPS enforced and some security headers implemented. However, the use of 'unsafe-inline' and 'unsafe-eval' in the Content-Security-Policy introduces potential XSS risks. The absence of DNSSEC and lack of published incident response or vulnerability disclosure policies indicate gaps in security governance. No exposed sensitive data or vulnerable libraries were detected in the provided content. Compliance with privacy regulations is basic, with privacy and cookie policies present but limited GDPR indicators. The security culture appears functional but could benefit from formalized policies and stronger technical controls.

Recommendations

  1. Strengthen Content-Security-Policy by removing 'unsafe-inline' and 'unsafe-eval' directives to mitigate XSS risks.
  2. Implement DNSSEC to enhance domain name system security and prevent DNS spoofing.
  3. Publish a security.txt file and incident response contact information to improve vulnerability disclosure and incident handling transparency.
  4. Add additional security headers such as HSTS, X-Frame-Options, and X-Content-Type-Options for layered defense.
  5. Enhance GDPR compliance by providing clearer user consent mechanisms and data retention policies.

Technical notes

Notes

The website uses a custom-built CMS with a technology stack including jQuery 3.1.0, UA-Parser.js, Kakao SDK, Slick Slider, bxSlider, and Cordova for mobile app integration. The site is moderately performant with good mobile optimization and basic accessibility features. SEO is basic but present with meta tags and Open Graph properties. Hosting appears to be managed by Gabia, a Korean registrar and hosting provider. The site uses HTTPS and includes cache control headers. There is some technical debt indicated by the use of older jQuery versions and permissive CSP settings. Opportunities exist to modernize the tech stack, improve security headers, and enhance accessibility and SEO for better user experience and compliance.
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.
