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

Hentai Kai is a niche adult content website specializing in translated hentai mangas, doujinshis, erotic comics, 3D hentai comics, and hentai anime streaming and downloads, primarily targeting Portuguese-speaking audiences. The site operates on a WordPress platform with Cloudflare DNS and GoDaddy domain registration, employing modern performance optimization techniques such as WP Rocket and lazy loading. While the website offers a good user experience with clear navigation and relevant content, it lacks critical privacy and security policies, including privacy and cookie policies, GDPR compliance indicators, and security headers. The absence of contact information and incident response channels further limits its business credibility and compliance posture. The domain registration is consistent and appropriate for the business age and market niche. Strategic improvements in security practices, privacy compliance, and transparency would enhance trust and reduce risk.

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

7 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 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 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

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

The website positions itself as a specialized content provider in the adult media sector, focusing on hentai manga and anime for Portuguese-speaking users, likely in Brazil. Its business model relies on affiliate marketing and advertising, linking to partner adult content sites. The partnership ecosystem includes several known adult content platforms, enhancing its market reach. The site is relatively young, founded in 2018, and maintains a moderate content quality and branding consistency. However, the lack of formal business contact details and compliance documentation suggests a small-scale operation with limited formalization. Growth potential exists through improved compliance and security measures.

Security posture

The current security posture is basic, with HTTPS enabled but lacking DNSSEC and critical security headers such as Content-Security-Policy and HSTS. No explicit security or incident response policies are published, and no abuse or security contact emails are found. The use of third-party scripts like Google Analytics and Disqus introduces tracking and potential vulnerabilities, with no visible mitigation or user consent mechanisms. The domain status flags provide some protection against unauthorized domain changes. Overall, the site is vulnerable to common web security risks and lacks transparency in security governance.

Recommendations

  1. Enable DNSSEC to secure DNS resolution and prevent spoofing.
  2. Implement and publish comprehensive privacy and cookie policies with GDPR compliance measures.
  3. Add security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and HSTS.
  4. Publish contact information including security incident response and abuse contacts.
  5. Conduct regular security audits of third-party scripts and implement consent mechanisms for tracking.

Technical notes

Notes

The website uses WordPress CMS with Cloudflare DNS and GoDaddy domain registration. It employs modern front-end optimization techniques such as lazy loading and WP Rocket caching. Google Analytics and Google Tag Manager are used for analytics, and Disqus for comments. The site is mobile optimized with responsive design and good SEO meta tags. However, no advanced frameworks or backend technologies are evident. Performance is moderate, with some broken lazy loading images noted. Accessibility features are basic, and no ARIA or enhanced accessibility tags are detected. The technical stack is typical for a small to medium content website but could benefit from improved security and privacy technical implementations.
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.
