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

JPTeacher.com is a niche adult entertainment website specializing in Japanese teacher-themed pornographic videos, movies, and DVDs. The business operates on a subscription model providing access to a large archive of over 5000 videos and a network of 21 related adult sites. The company behind the site is OWLISION LTD, based in London, UK, with a domain registration dating back to 2009, indicating an established presence in the adult media market. The site targets an adults-only audience with explicit content and no visible age verification mechanisms in the HTML content. Technically, the website uses legacy JavaScript libraries such as jQuery 1.7.1, Google Tag Manager, Yandex Metrika, and Sentry for analytics and error tracking. The site is mobile optimized and provides a generally good user experience with clear navigation and professional design. However, the technical stack shows some outdated components and lacks modern security headers and cookie consent mechanisms, which impacts privacy compliance and security posture. Security-wise, the site enforces HTTPS but does not implement DNSSEC and uses an outdated jQuery version with known vulnerabilities. No explicit security or incident response policies are found on the site. Payment processing is handled by multiple reputable third-party vendors, enhancing trust in transaction security. Overall, the site is functional and professional but would benefit from security and privacy improvements to enhance user trust and compliance.

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.

Priority findings

6 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

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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 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 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

Business profile

JPTeacher.com occupies a niche segment within the adult entertainment industry, focusing on Japanese teacher-themed content. Its subscription-based business model leverages a network of 21 sites to provide extensive content variety and value. The company OWLISION LTD appears to be the sole legal entity operating the site, with no subsidiaries detected. The site’s competitive advantage lies in its specialized content and large archive, appealing to a specific adult audience. Revenue streams include subscriptions and DVD sales, supported by affiliate marketing through the Idolbucks network. The partnership ecosystem includes multiple payment processors ensuring smooth financial transactions. Growth indicators include regular content updates and a broad network presence. However, the lack of visible contact emails or phone numbers may limit direct customer engagement. The site’s marketing relies heavily on tracking and analytics tools, though privacy compliance is minimal.

Security posture

The security posture of JPTeacher.com is moderate but shows room for improvement. HTTPS is properly implemented, ensuring encrypted data transmission. However, the absence of DNSSEC reduces domain name system security. The use of an outdated jQuery version introduces potential client-side vulnerabilities. No security headers such as Content Security Policy (CSP), X-Frame-Options, or X-XSS-Protection are detected, which could expose the site to common web attacks. The site uses Sentry for error monitoring, indicating some level of operational security awareness. No explicit security policies, incident response contacts, or vulnerability disclosure mechanisms are present, which limits transparency and readiness for security incidents. Privacy compliance is weak, with no cookie consent mechanism and minimal GDPR indicators. Overall, the site is functional but should prioritize updating libraries, implementing security headers, and enhancing privacy controls to reduce risk.

Recommendations

  1. Upgrade jQuery and other JavaScript libraries to the latest secure versions to mitigate known vulnerabilities.
  2. Implement DNSSEC to enhance domain name system security and prevent DNS spoofing.
  3. Add comprehensive security headers including Content Security Policy, X-Frame-Options, and X-XSS-Protection.
  4. Introduce a cookie consent banner and privacy controls to improve GDPR compliance and user trust.
  5. Publish clear security and incident response policies with dedicated contact channels to enhance transparency and readiness.

Technical notes

Notes

The website is built using legacy JavaScript libraries such as jQuery 1.7.1, which is outdated and vulnerable. It integrates multiple third-party analytics and tracking services including Google Tag Manager, Yandex Metrika, and Sentry for error monitoring. The site uses SlidesJS for sliders and jPlayer for media playback. No CMS or modern web frameworks are detected, indicating a custom or legacy-built platform. Hosting details are not explicit but DNS uses anycastns1.org and anycastns2.org name servers, with domain registered via GoDaddy. Performance is moderate with mobile optimization rated good. SEO is basic with meta tags present but no advanced structured data like JSON-LD or Open Graph tags detected. Accessibility features are minimal. The site would benefit from modernization of its tech stack, improved security configurations, and enhanced SEO and accessibility practices.
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.
