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

The website jav.sb is a large-scale adult video streaming platform specializing in Japanese adult videos (JAV), including censored, uncensored, FC2-PPV, and mosaic removed content. It offers free streaming services with a membership option for video collection and supports multiple languages, targeting an adult-only audience. The site features a modern design with good navigation and mobile optimization, leveraging technologies such as jQuery, Layui, and MacCMS as its CMS platform. Analytics are implemented via Yandex Metrika. However, the site lacks visible privacy, cookie, and terms of service policies, as well as contact or incident response information, which impacts its privacy compliance and business credibility scores. Security posture is moderate with HTTPS enabled but missing important security headers. Overall, the site is functional and content-rich but requires improvements in privacy and security 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

8 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 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';…

  3. 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

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

jav.sb operates in the adult media industry, providing free access to a vast library of Japanese adult videos with various categories and language options. Its business model appears to rely on free streaming with optional membership for content collection. The site maintains partnerships with numerous adult content directories and related platforms, enhancing its market reach. The absence of company contact details and privacy policies suggests a focus on anonymity typical in adult entertainment. The platform's multi-language support and extensive content catalog position it as a competitive player in the adult streaming market.

Security posture

The website employs HTTPS ensuring encrypted communications, and uses asynchronous script loading for performance. However, it lacks critical security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are essential to mitigate common web vulnerabilities. No privacy or cookie policies are presented, indicating non-compliance with GDPR and other privacy regulations. There is no visible incident response or abuse contact information, which is a gap in security readiness. The use of third-party analytics (Yandex Metrika) introduces moderate user tracking without clear privacy disclosures. Overall, the security posture is moderate but requires enhancements in policy transparency and header implementation.

Recommendations

  1. Publish comprehensive privacy and cookie policies to improve compliance and user trust.
  2. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against web attacks.
  3. Add clear contact information for security incidents and abuse reporting to improve incident response readiness.
  4. Review and disclose data collection and retention practices related to analytics and tracking.
  5. Regularly audit third-party scripts and dependencies to avoid vulnerabilities and ensure secure integrations.

Technical notes

Notes

The website uses a modern frontend stack including HTML5, CSS3, JavaScript, and jQuery, with the MacCMS content management system and Layui framework for UI components. It is optimized for mobile devices and supports multiple languages, enhancing accessibility and user experience. Performance is moderate with asynchronous loading of analytics scripts. SEO is supported by proper meta tags and structured navigation. However, the absence of security headers and privacy policies indicates technical debt in security and compliance areas. Hosting provider details are not disclosed, limiting infrastructure assessment. Overall, the technical implementation is solid but requires security and privacy 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.
