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

NHN Dooray Corporation operates Dooray!, a comprehensive SaaS collaboration platform primarily targeting enterprises, public institutions, educational organizations, and financial institutions in South Korea. The platform integrates project management, messaging, email, video conferencing, and other business collaboration tools into a unified service. The company holds a strong market position in Korea, especially within regulated sectors such as finance and government, supported by multiple international and domestic security certifications. Technically, the website is built on modern frameworks such as Next.js and React, hosted on NHN Cloud infrastructure, and employs extensive analytics and marketing tools. Security posture is robust with HTTPS enforcement, data encryption, and recognized certifications, though some security headers and incident response disclosures could be improved. Overall, the website is professional, well-structured, and trustworthy, with clear business and contact information. Privacy compliance is adequate but could be enhanced with explicit cookie consent mechanisms and GDPR-related disclosures.

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

Dooray! serves a broad enterprise customer base with a SaaS model supplemented by an on-premise package for customers with strict security requirements. Its competitive advantage lies in its all-in-one collaboration suite, strong security certifications, and deep penetration in public and financial sectors. Revenue streams likely include subscription fees across multiple service tiers and add-ons such as AI features. The company maintains a strong partnership ecosystem and invests in marketing and analytics to support growth. The presence of numerous customer logos from diverse sectors indicates a mature and trusted product. Strategic observations include the importance of maintaining compliance with evolving data protection laws and expanding AI capabilities to stay competitive.

Security posture

The security maturity of Dooray! is high, evidenced by multiple ISO and domestic certifications, encrypted data storage, and secure cloud hosting. The website uses HTTPS and integrates security monitoring scripts. However, the absence of a public vulnerability disclosure policy and incident response contact information represents a compliance gap. Security headers are not fully confirmed in the HTML, suggesting potential for improvement. No vulnerabilities or exposed sensitive data were detected in the analysis. The company should consider publishing a security.txt file and enhancing transparency around incident response to strengthen trust and compliance.

Recommendations

  1. Publish and enforce comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Implement and display a public vulnerability disclosure policy and provide incident response contact channels.
  3. Add explicit cookie consent banners or mechanisms to improve privacy compliance and user transparency.
  4. Regularly audit and update third-party libraries and scripts to avoid potential vulnerabilities.
  5. Enhance data protection officer contact visibility and GDPR compliance documentation.

Technical notes

Notes

The website leverages a modern tech stack including Next.js and React, ensuring good performance and mobile optimization. Hosting on NHN Cloud provides a reliable infrastructure foundation. The use of multiple analytics and marketing tools indicates a mature digital marketing strategy but also increases the complexity of privacy management. The site is well-structured with comprehensive meta tags and SEO optimizations. Some legacy scripts like jQuery are still present but do not appear to impact performance significantly. Overall, the technical implementation supports a fast, accessible, and user-friendly experience with room for incremental 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.
