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

OnlyMaestros is a specialized music education platform organizing conducting masterclasses featuring internationally recognized maestros. It operates as a department of Only Stage Ltd, an arts management and production company based in London, UK. The website presents a professional image with detailed course offerings and collaborations with prestigious orchestras and institutions. Technically, the site is built on WordPress using modern themes and plugins, with good mobile optimization and SEO practices. Security posture is adequate with HTTPS enabled but lacks advanced security headers and DNSSEC. Privacy compliance is partial, with cookie consent implemented but no visible privacy or terms policies. Overall, the site is credible and trustworthy for its niche audience but could improve compliance and security transparency.

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

7 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 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"

  3. 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

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 targets conductors and musicians seeking advanced training through masterclasses led by renowned conductors. Its competitive advantage lies in direct interaction with professional orchestras and a strong network via Only Stage Ltd. Revenue likely derives from course fees and artist management. The company maintains partnerships with major cultural institutions worldwide, enhancing its market position. Growth indicators include scheduled masterclasses for 2025 and a roster of over 40 artists. The business model combines education, artist management, and arts project development.

Security posture

The website demonstrates a basic security maturity level with HTTPS and domain transfer protection. However, it lacks DNSSEC and security headers such as Content Security Policy or HSTS, which are recommended best practices. No explicit security policies or incident response contacts are provided, indicating limited transparency in security governance. The absence of vulnerability disclosure or security.txt files suggests room for improvement in security culture and readiness. No exposed sensitive data or vulnerable libraries were detected in the analysis.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service to improve compliance.
  2. Enable DNSSEC on the domain to enhance DNS security.
  3. Add security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  4. Publish a security policy and incident response contact information to improve transparency and trust.
  5. Regularly audit and update WordPress plugins and themes to mitigate vulnerabilities.

Technical notes

Notes

The website uses a modern WordPress infrastructure with Astra theme and Elementor page builder, ensuring good design flexibility and responsiveness. Google Analytics and Facebook Pixel are integrated for analytics and marketing. Cookie consent is managed by CookieYes. Hosting is provided by HOSTINGER operations, UAB, a reputable provider. Performance is moderate with no major issues detected. Accessibility features are basic but present. SEO is enhanced by Yoast SEO plugin and proper meta tags including Open Graph and JSON-LD structured data. Technical risks include lack of DNSSEC and missing security headers.
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.
