(주)도플소프트 · Transportation · South Korea
Medium risk. 6 critical or high findings in Security headers, GDPR outside view and 1 other check.
도플소프트는 한국 내 대중교통 이용자를 위한 스마트 모바일 앱 개발 및 서비스를 제공하는 전문 기업입니다. 주요 앱으로는 지하철 종결자, 전국 스마트 버스, 스마트 무브 등이 있으며, NHN 계열사로서 안정적인 시장 위치를 확보하고 있습니다. 웹사이트는 한국어로 제공되며, 대중교통 관련 정보와 앱 다운로드를 중심으로 구성되어 있습니다. 기술적으로는 jQuery와 Swiper.js를 활용한 모던한 UI를 제공하며, 모바일 최적화도 양호한 편입니다. 보안 측면에서는 HTTPS가 적용되어 있으나, DNSSEC 미적용과 보안 헤더 부재 등 개선 여지가 있습니다. 개인정보 처리방침과 이용약관이 명확히 제공되나, 쿠키 정책 및 보안 정책은 미흡합니다. 전반적으로 신뢰할 수 있는 기업 웹사이트로 평가되며, 보안 및 개인정보 보호 강화가 권장됩니다.

NIS2 Art. 21(2)
- (a) Risk analysis and security policies: Not visible from outside

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.
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
- RFC 6797 §6.1.1

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.
Counted in this score
- SSL/TLS
- 72
- Security headers
- 15
- Email security

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.

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.
