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

Byapps operates in the technology and e-commerce sectors, providing SaaS and managed services for mobile app creation and operation. Their business model leverages free app production to attract clients, supplemented by value-added services such as app marketing consulting and operational management.

Strategic observations include a strong emphasis on customer retention via app marketing and personalized app features, positioning Byapps as a comprehensive solution provider in the Korean mobile app market.

Security posture

The website maintains a moderate security posture with HTTPS enforced and domain transfer protection enabled. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No explicit security or incident response policies are publicly disclosed, and no vulnerability disclosure or security.txt files are found, which may impact transparency and trust. The extensive use of third-party tracking and marketing scripts increases the attack surface and privacy considerations. Overall, while no critical vulnerabilities are evident, enhancements in security headers, privacy compliance (cookie consent), and public security policies would strengthen the security maturity.

Recommendations

  1. Implement Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options headers to improve security.
  2. Add a cookie consent banner and privacy compliance mechanisms to meet GDPR and other privacy regulations.
  3. Publish a security policy and incident response contact information to enhance transparency and trust.
  4. Conduct regular audits of third-party scripts to mitigate risks from external dependencies.
  5. Consider establishing a vulnerability disclosure program or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website uses a modern and responsive design framework (Bootstrap 5) combined with popular JavaScript libraries such as jQuery and Swiper.js for interactive elements. Google Fonts and AOS animations enhance visual appeal and user experience. The site loads multiple external analytics and marketing scripts, indicating a sophisticated tracking and marketing infrastructure. Performance is moderate, with good mobile optimization and accessibility features. No CMS is explicitly detected, suggesting a custom or static site architecture. Hosting provider details are not explicitly identified. Technical risks include reliance on multiple third-party scripts without visible CSP enforcement, which could expose the site to script injection risks.
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.
