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

13 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • Critical

      Critical Service Exposed: PostgreSQL

      Port 5432 (PostgreSQL) is publicly accessible - PostgreSQL - Database server

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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"

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 · found on this site
  • 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 company targets aspiring DJs and music producers, offering a range of courses including DJ techniques, music production, and event hosting (wodzirej). Their competitive advantage lies in personalized instruction by active professionals and flexible scheduling. Revenue streams include paid courses and workshops, both in-person and online. The company maintains an active social media presence and uses modern marketing and analytics tools. Growth potential is supported by multiple city locations and eLearning offerings. No direct partnerships or subsidiaries were identified from the data.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, DNSSEC enabled, and a cookie consent mechanism compliant with GDPR principles. However, the absence of publicly available privacy policy, terms of service, security policy, and incident response contacts represents compliance and transparency gaps. No vulnerabilities or exposed sensitive data were detected. The use of third-party scripts like Google Tag Manager and Microsoft Clarity is standard but requires ongoing monitoring. Overall, the security maturity is good but could be improved by publishing formal policies and enhancing security headers.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages accessible from the website footer or main menu.
  2. Add a dedicated security policy page including incident response procedures and contact channels for security issues.
  3. Implement additional HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Regularly audit and update third-party scripts and plugins to mitigate potential vulnerabilities.
  5. Enhance cookie consent details with explicit information on data retention and user rights to improve GDPR compliance.

Technical notes

Notes

The website is built on a modern WordPress CMS platform with WooCommerce for e-commerce capabilities. It uses jQuery and integrates Google Tag Manager and Microsoft Clarity for analytics and user behavior tracking. The site includes a Progressive Web App (PWA) manifest and is mobile-optimized with responsive design. Performance is moderate with room for optimization. Accessibility features are present, and SEO is well implemented with structured data (JSON-LD) for organization, courses, and articles. Hosting provider details are not explicitly identified. The technical stack is standard for educational e-commerce sites and supports scalability and user engagement.
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.
