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

Tonstudio Rajchman is a Czech Republic-based media services company specializing in event sound systems, music recording, videostudio services, music publishing, production and graphics, equipment sales, AV installations, streaming, and concerts. The company appears to be a small, established local business with a domain registered since 2001, indicating a stable market presence. The website is professionally designed with good content relevance and navigation, targeting musicians, event organizers, and media production clients. Technically, the site uses common JavaScript libraries such as jQuery and Lightbox, hosted on Websupport servers, with moderate performance and good mobile optimization. However, the site lacks advanced security headers and HTTPS status is unknown from the provided data. No privacy or cookie policies are present, and no contact emails or phone numbers are explicitly listed, which may impact user trust and compliance. The security posture is basic with room for improvement in SSL configuration and security best practices. Overall, the website is functional and professional but would benefit from enhanced security and compliance features.

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

9 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

    • 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

  2. 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

  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"

      • 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"

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

Tonstudio Rajchman operates in the media sector, providing a broad range of audio-visual and music-related services. Its business model combines service offerings with an e-commerce component for equipment sales. The company targets a niche audience of musicians and event professionals within the Czech Republic. The domain age and registration data support a credible and consistent business history. The lack of visible certifications or trust badges suggests a focus on local reputation rather than formal industry certifications. The presence of an e-shop indicates diversification of revenue streams. The company’s partnership ecosystem is not evident from the website content. Growth indicators and strategic partnerships are not disclosed.

Security posture

The website currently exhibits a basic security posture. There is no evidence of HTTPS enforcement or security headers such as Content-Security-Policy or X-Frame-Options. No vulnerability disclosure or incident response information is provided, and no security contact channels are visible. The absence of privacy and cookie policies indicates potential GDPR compliance gaps. No analytics or tracking scripts were detected, which reduces privacy risks but also limits business intelligence capabilities. The site uses common JavaScript libraries without indication of outdated or vulnerable versions. Overall, the security maturity is low to moderate, with recommendations to implement HTTPS, security headers, and formal privacy and security policies to improve compliance and trust.

Recommendations

  1. Implement HTTPS with a valid SSL certificate and enforce secure connections site-wide.
  2. Add comprehensive privacy and cookie policies to comply with GDPR and inform users.
  3. Deploy security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Publish incident response and vulnerability disclosure information with dedicated contact channels.
  5. Include clear contact information such as company emails and phone numbers to enhance trust and compliance.

Technical notes

Notes

The website is built on a custom or unknown CMS platform using standard web technologies including jQuery, ResponsiveSlides.js, and Lightbox for UI components. The hosting provider is Websupport, a Czech hosting service, consistent with the domain's regional focus. The site includes well-formed meta tags and Open Graph data for SEO and social sharing. Mobile optimization is good, supported by viewport settings and responsive scripts. However, no modern frameworks or CMS platforms like WordPress, Joomla, or Drupal were detected. Performance is moderate with no explicit indicators of optimization or caching. Accessibility features are basic, with no ARIA roles or landmarks detected in the provided HTML snippet. There is no evidence of analytics or marketing tools integrated. The technical debt appears low but modernization opportunities exist, especially in security and compliance implementations.
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.
