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

Nutaku Entertainment Ltd operates Nutaku.net, a leading adult gaming platform specializing in porn, hentai, and sex games. The website offers both free and paid games, affiliate marketing, and publishing services, targeting adult gamers worldwide. The platform supports multiple languages and enforces age verification to comply with legal requirements. Technically, the site uses modern web technologies including JavaScript, Google reCAPTCHA, and tracking tools like Atlas for analytics and advertising. The site is mobile optimized with good SEO and accessibility features. Security posture is strong with HTTPS enforcement and anti-bot protections, though some security headers are missing and no explicit security policy or incident response contact is provided. The absence of WHOIS data reduces transparency and trustworthiness, but the professional presentation and comprehensive privacy and cookie policies indicate a mature business. Overall, the site is functional, secure, and compliant with privacy regulations, but could improve in transparency and security disclosures.

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

5 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 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

  3. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  4. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Weak SPF Policy

      SPF record has permissive policy allowing any server to send email

      What to do: Use -all or ~all qualifier for better email security

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

Nutaku.net holds a strong market position as a top adult gaming platform with a diversified business model including game publishing and affiliate marketing. Its target audience is adult gamers interested in explicit content. The company leverages partnerships such as its affiliate program to expand reach. The website's multi-language support and regular promotional events indicate active user engagement and growth focus. However, the lack of publicly available WHOIS data and contact information may pose challenges for trust and regulatory compliance. The business operates primarily in the media sector with a large scale indicated by the breadth of services and content. Strategic partnerships and a clear brand identity support its competitive advantage in the niche adult gaming market.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and Google reCAPTCHA protecting user forms against automated abuse. Cookie consent mechanisms comply with GDPR requirements, and age verification is prominently implemented. However, the absence of key security headers such as Content-Security-Policy and lack of a published security policy or incident response contact reduce the overall security maturity. No vulnerabilities or exposed sensitive data were detected in the provided content. The site would benefit from publishing a vulnerability disclosure policy and improving transparency around security practices to enhance user trust and compliance readiness.

Recommendations

  1. Implement and publish a comprehensive security policy including incident response contacts.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection.
  3. Publish a vulnerability disclosure or security.txt file to encourage responsible reporting.
  4. Provide clear company contact information including security and support emails to improve transparency.
  5. Enhance accessibility features to meet higher standards and improve user experience for all users.

Technical notes

Notes

The website uses a modern JavaScript-based front-end with asynchronous loading and integration of Google reCAPTCHA for bot protection. Tracking and analytics are managed via Atlas and other third-party services. The site is mobile optimized and supports multiple languages, indicating a mature international platform. Performance is moderate with room for improvement in loading speed and accessibility. No CMS or hosting provider information was detected. The technical implementation is solid but could benefit from additional security headers and improved accessibility compliance to reduce technical debt and enhance resilience.
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.
