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

Nanairo.co operates as a Japanese adult video streaming platform offering free membership access to curated amateur and female-oriented adult videos. The site targets an adult audience with explicit age verification and regional access restrictions, positioning itself as a niche player in the Japanese adult media market. Key services include video streaming, live streams, auctions, photo galleries, and curated lists. The business model relies on free access, likely monetized through advertising or ancillary services. Technically, the site leverages modern web technologies including Google Analytics, Google Tag Manager, OneSignal for notifications, jQuery, and Video.js for media playback, hosted on Amazon AWS infrastructure. The site is mobile optimized with a responsive design and basic accessibility features. Security posture is moderate with HTTPS enabled and CSRF protections, but lacks DNSSEC and explicit security headers. Privacy compliance is limited, with no cookie consent mechanism and only basic privacy and terms pages. Contact is available only via web form, with no direct emails or phone numbers published. WHOIS data is privacy protected but consistent with the site's Japanese origin and domain age, supporting legitimacy. Overall, the site is functional and professionally presented but could improve security and privacy 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 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Twitter, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

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

Nanairo.co occupies a specialized segment within the adult entertainment industry in Japan, focusing on free access to high-quality amateur and female-oriented adult videos. Its competitive advantage lies in curated content and a membership model that does not charge fees upfront. The presence of live streams and auctions suggests diversified revenue streams beyond video content. The company maintains an official support domain and active social media channels on Twitter and YouTube, enhancing user engagement and brand presence. The business appears small but established since 2015, with consistent branding and a clear target audience of adults. The use of privacy protection in WHOIS is typical for adult content providers to safeguard registrant identity. The lack of direct contact details and limited public security policies may reflect operational choices in a sensitive industry. Strategic partnerships or payment processors are not explicitly identified in the data.

Security posture

The website demonstrates a moderate security posture with mandatory HTTPS and CSRF token implementation, indicating awareness of basic web security practices. However, the absence of DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options reduces defense-in-depth. No public security or incident response policies were found, and no vulnerability disclosure or security.txt files are present, limiting transparency and user trust in security incident handling. The site uses third-party analytics and notification services, which may introduce privacy considerations. Age verification is implemented via a modal dialog, enforcing compliance with adult content regulations. Overall, while no critical vulnerabilities are evident, improvements in security headers, DNSSEC, and public security documentation are recommended to enhance resilience and compliance.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  3. Add a cookie consent banner and explicit cookie policy to comply with GDPR and other privacy regulations.
  4. Publish a clear security policy and incident response plan to increase transparency and user trust.
  5. Consider providing direct contact emails for security and abuse reporting to facilitate incident handling.

Technical notes

Notes

The website is built on a modern technology stack inferred to be Ruby on Rails, using asset pipeline conventions and CSRF protections. It integrates widely used libraries and services such as jQuery, Video.js for media playback, FontAwesome for icons, and Google Analytics and Tag Manager for tracking. Hosting is on Amazon AWS with Cloudfront CDN usage for media assets, supporting scalability and performance. The site is responsive and mobile optimized with adaptive CSS. However, no CMS is explicitly detected, suggesting a custom or framework-based implementation. Performance is moderate with asynchronous loading of analytics scripts. Accessibility is basic with some semantic HTML but no advanced ARIA roles detected. SEO optimization is basic with meta description and canonical tags but no Open Graph or JSON-LD structured data found. Overall, the technical infrastructure is solid but could benefit from enhanced SEO and accessibility improvements.
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.
