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

4Tube.icu is an adult entertainment website offering free streaming and downloadable pornographic videos. The site targets an adults-only audience and operates as a free porn tube platform monetized primarily through advertising. The domain is recently registered and uses privacy protection services, which is common in this industry but reduces transparency. Technically, the site uses standard web technologies with Cloudflare DNS but lacks advanced security headers and privacy compliance mechanisms. There is no visible privacy policy, cookie consent, or contact information, which poses compliance and trust challenges. The site includes multiple third-party ad and tracking scripts, indicating extensive user tracking.

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 model is based on aggregating adult video content from third parties and monetizing via ads. The site targets adult consumers seeking free pornographic content. Market positioning is typical for free tube sites, competing in a crowded adult media sector. The use of privacy protection and recent domain registration suggests a new entrant with limited public business information. No partnerships or certifications are evident. The site’s content and service offerings are basic but functional, focusing on video streaming and downloads.

Security posture

Security posture is weak with no published security policies, no visible security headers, and no incident response contacts. The site uses Cloudflare DNS but does not enable DNSSEC. The presence of multiple third-party ad and tracking scripts increases risk exposure. Lack of HTTPS confirmation is a concern, though likely present. No vulnerability disclosure or data protection officer information is available. Overall, the site lacks mature security and privacy practices, which is typical but risky in adult content domains.

Recommendations

  1. Publish comprehensive privacy and cookie policies with GDPR compliance details.
  2. Implement and enforce HTTPS with strong SSL/TLS configurations and security headers.
  3. Provide clear contact information including abuse and security incident channels.
  4. Add age verification or adult content warnings to comply with legal requirements.
  5. Reduce third-party tracking or improve transparency and user consent mechanisms.

Technical notes

Notes

The website uses standard HTML5 and JavaScript with Cloudflare DNS hosting. The site loads multiple third-party ad and tracking scripts, some obfuscated. Mobile optimization is basic but present. SEO metadata is minimal but includes keywords and descriptions. No CMS or advanced frameworks detected. Performance is moderate with some heavy scripts. Accessibility features are minimal. The site lacks modern security headers and DNSSEC is not enabled. Overall, the technical infrastructure is functional but lacks modern security and privacy enhancements.
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.
