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

nHentai.io is a niche adult content website specializing in free hentai manga and doujinshi distribution. The platform targets adult manga enthusiasts seeking uncensored and translated hentai comics. It operates primarily as a free content provider monetized through advertising networks. Technically, the site runs on WordPress with common SEO and security plugins, hosted via Cloudflare, and integrates Google Analytics and reCAPTCHA for analytics and bot protection. While the site is accessible and functional with good content quality and mobile optimization, it lacks critical privacy and security policies, including privacy, cookie, and terms of service pages. No contact or incident response information is provided, which reduces business credibility and user trust. Security headers are missing, and advertising practices rely heavily on third-party ad networks, which may impact user privacy. Overall, the site is operational but requires significant improvements in privacy compliance and security posture to enhance trustworthiness and regulatory adherence.

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

The business operates in the adult entertainment sector, focusing on hentai manga and doujinshi. It leverages free content distribution supported by advertising revenue. The market position is that of a popular niche platform with a dedicated adult audience. Partnerships with other adult content sites like hentaihaven.xxx and hentaidude.xxx suggest a networked ecosystem. The business is relatively young, founded in 2020, with a small operational scale. The lack of formal contact information and policies indicates a low emphasis on corporate transparency. Growth potential exists within the adult manga niche, but regulatory and trust challenges must be addressed.

Security posture

The website employs HTTPS and Google reCAPTCHA, indicating basic security awareness. However, the absence of security headers such as CSP, HSTS, and X-Frame-Options exposes the site to potential risks like clickjacking and content injection. No vulnerability disclosure or incident response mechanisms are visible, limiting the ability to manage security incidents effectively. The heavy use of third-party advertising scripts increases the attack surface and privacy risks. Overall, the security posture is moderate but requires enhancements to meet best practices and compliance standards.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers including Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  3. Establish and publish a vulnerability disclosure policy and incident response contact channels.
  4. Provide clear business contact information to improve credibility and user trust.
  5. Audit and limit third-party scripts and advertising networks to reduce privacy and security risks.

Technical notes

Notes

The site is built on WordPress 6.4.3 with Yoast SEO and Script Manager plugins, indicating a standard CMS-based infrastructure. It uses Google Fonts and Font Awesome for UI elements and integrates Google reCAPTCHA for bot mitigation. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. Performance is moderate with mobile optimization present. However, accessibility features are basic, and SEO is adequately addressed via meta tags and structured data. The site relies heavily on third-party ad networks, which may affect load times and privacy. No advanced frameworks or custom platforms detected.
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.
