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

Rakuten Viki is a well-established video streaming platform specializing in Asian dramas and movies, offering free and subscription-based content with English subtitles. It operates under the Rakuten brand, leveraging a strong market position in niche media streaming. The platform supports community contributions and interactive features such as Watch Parties, enhancing user engagement. Technically, the website is built on modern frameworks like Next.js and integrates multiple analytics and privacy management tools, reflecting a mature digital infrastructure. Security posture is strong with HTTPS, nonce-based CSP, and privacy consent mechanisms, though explicit security policies and incident response contacts are not published. Overall, the site is professional, trustworthy, and compliant with privacy regulations, though WHOIS data is unavailable, likely due to privacy protection. Strategic recommendations include publishing security policies, vulnerability disclosure programs, and enhancing transparency on data protection roles.

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

3 findings rated critical or high. Fix these first.

  1. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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 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';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

Rakuten Viki occupies a niche in the media streaming industry focused on Asian content, targeting a general audience interested in Korean, Chinese, and Japanese dramas. Its business model combines free ad-supported streaming with a premium subscription (Viki Pass) and transactional video on demand. The platform benefits from Rakuten's global brand and ecosystem, linking to related Rakuten services and affiliate programs. The company leverages social media and community engagement to maintain a loyal user base. Growth indicators include multi-platform availability and interactive features. Partnerships with Rakuten subsidiaries and affiliates strengthen its market presence. The absence of direct contact information on the site suggests a focus on digital self-service and community support.

Security posture

The website demonstrates a solid security foundation with HTTPS enforcement, Content Security Policy using nonces, and integration of privacy management scripts to comply with GDPR and CCPA. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the lack of publicly available security policies, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. The use of multiple third-party analytics and marketing scripts necessitates ongoing security audits to mitigate supply chain risks. Overall, the security posture is good but could be enhanced by formalizing and publishing security governance documents.

Recommendations

  1. Publish a dedicated security policy page including incident response contacts to improve transparency and trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Add data protection officer contact information to comply with GDPR best practices and enhance user trust.
  4. Regularly review and audit third-party scripts and dependencies to minimize supply chain vulnerabilities.
  5. Enhance user support channels with clear contact information for security and privacy concerns.

Technical notes

Notes

The website uses a modern React-based framework (Next.js) optimized for performance and SEO, with server-side rendering and client-side hydration. It employs advanced privacy management tools and integrates multiple analytics platforms for user behavior tracking and performance monitoring. The site is mobile-optimized with responsive design and accessibility considerations. No CMS was explicitly detected, suggesting a custom or headless CMS approach. Hosting details are not explicit but likely use CDN and cloud infrastructure for global delivery. The technical stack supports scalability and user engagement features such as Watch Parties. Opportunities exist to improve documentation of technical security controls and to monitor third-party dependencies continuously.
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.
