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

WiderPlanet, operated by Artist Company, is a South Korean technology firm specializing in big data-driven targeted advertising services under the brand TargetingGates™. Established in 2010, the company offers a suite of digital marketing solutions including display, mobile, and premium ads, leveraging proprietary data management and retargeting technologies. Their market position is solid within Korea, supported by extensive data coverage of Korean internet users and partnerships with advertising technology providers. Technically, the website employs a modern tech stack with jQuery, Google Analytics, Facebook Pixel, and other marketing tools, hosted on AWS infrastructure. The site is mobile-optimized and SEO-friendly, though accessibility features are basic. Security posture is good with HTTPS and some security headers, but lacks DNSSEC and comprehensive security policies. Privacy compliance is basic with a privacy policy present but no cookie consent mechanism or GDPR-specific disclosures. Overall, the site is professional and trustworthy with clear business information and contact details, but could improve in privacy and security transparency.

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

6 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 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

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

WiderPlanet operates in the digital advertising technology sector, targeting advertisers and marketers seeking advanced audience targeting through big data analytics. Their business model revolves around data-driven ad delivery using DSP, DMP, and RTB platforms. The company benefits from a strong local presence in South Korea and partnerships with SSP providers like Adpies. Revenue streams likely include advertising campaign management fees and technology licensing. The company demonstrates growth potential through global business initiatives and advanced targeting technologies. The partnership ecosystem includes major analytics and social platforms, enhancing their market reach. Strategic observations suggest a focus on expanding data capabilities and improving compliance to meet international standards.

Security posture

The website demonstrates a moderate to good security maturity level with enforced HTTPS, Content-Security-Policy header, and use of reCAPTCHA to prevent automated abuse. However, the absence of DNSSEC, limited security headers, and lack of published security or incident response policies indicate gaps in security governance. No vulnerabilities or exposed sensitive data were detected in the HTML content. Compliance with GDPR and other privacy regulations appears minimal, with no cookie consent mechanism or detailed data retention policies. Incident response readiness is unclear due to missing contact channels for security issues. Overall, the security posture is adequate for a marketing technology firm but requires enhancements to meet higher compliance and security standards.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement a clear cookie consent mechanism to comply with GDPR and other privacy regulations.
  3. Publish detailed security policies and incident response procedures accessible on the website.
  4. Add additional security headers such as HSTS, X-Frame-Options, and X-Content-Type-Options.
  5. Enhance privacy policy to explicitly address GDPR compliance and data retention practices.

Technical notes

Notes

The website is built on a custom CMS or framework using jQuery and integrates multiple third-party marketing and analytics scripts including Google Analytics, Facebook Pixel, Naver Analytics, and Kakao SDK. Hosting is provided via AWS as indicated by DNS nameservers. Performance is moderate with asynchronous loading of scripts and mobile optimization present. SEO is well addressed with meta tags and Open Graph data, though accessibility features are basic. The site uses reCAPTCHA for bot mitigation. Technical risks include reliance on multiple external scripts which may impact privacy and performance, and lack of DNSSEC which could expose DNS spoofing risks. Opportunities exist to modernize the tech stack by reducing legacy jQuery usage and improving accessibility 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.
