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

RockOpera Praha is a unique cultural institution in the Czech Republic specializing in original rock operas that blend sophisticated rock music with theatrical and visual performances. Founded by Milan Steigerwald and Pavla Forest, it serves a niche audience of rock music enthusiasts and theatre lovers, offering live shows, an online singing school, recorded performances, and venue rental services. The website reflects a professional and consistent brand presence with clear contact and legal information, supporting its credibility in the hospitality and media sectors. Technically, the website is built on the Webnode CMS platform, leveraging AWS Cloudfront CDN for hosting and performance optimization. It integrates modern tracking and marketing tools such as Google Tag Manager and Facebook Pixel, indicating a moderate level of digital maturity. The site is mobile-optimized and SEO-friendly, providing a good user experience. From a security perspective, the site uses HTTPS with good SSL configuration and secure form handling. However, it lacks explicit security headers and publicly available security policies or incident response information, which could be improved to enhance trust and compliance. Privacy compliance is addressed with a cookie consent mechanism and a privacy policy, though more detailed GDPR compliance indicators could be added. Overall, the website and business appear legitimate and well-managed, with no signs of malicious activity or content safety concerns. The absence of WHOIS data limits domain registration insights but is likely due to privacy protection, which is reasonable for this business type. Strategic recommendations include enhancing security headers, publishing a security policy, and maintaining regular audits of third-party scripts.

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

4 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. 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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

RockOpera Praha occupies a unique market position as the only Czech theatre producing original rock operas, combining music, theatre, and visual spectacle. Its business model includes live performances, ticket sales, educational offerings, and digital content distribution. The company targets cultural tourists, rock music fans, and theatre audiences, leveraging partnerships for ticketing and online presence. The website's multilingual support and active social media channels indicate efforts to reach international audiences. The business is small-sized but professionally operated, with clear legal and contact information enhancing trust. Growth opportunities may lie in expanding digital offerings and partnerships.

Security posture

The website demonstrates a moderate to good security posture with enforced HTTPS, secure form inputs, and no visible sensitive data exposure. The use of third-party tracking scripts is standard but requires ongoing monitoring for vulnerabilities. The lack of security headers and absence of a published security or incident response policy represent gaps in security maturity. No vulnerabilities or suspicious activities were detected in the content or scripts. GDPR compliance is partially addressed through privacy and cookie policies, but explicit data protection officer contact or vulnerability disclosure mechanisms are missing. Overall, the security posture is adequate for the business size but could be improved with formal policies and enhanced technical controls.

Recommendations

  1. Implement and configure security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web attacks.
  2. Publish a clear security policy and incident response plan accessible to users and partners to improve transparency and preparedness.
  3. Regularly audit and update third-party scripts and tracking pixels to prevent vulnerabilities and ensure compliance.
  4. Enhance GDPR compliance by providing explicit data protection officer contact information and detailed privacy practices.
  5. Maintain and improve website accessibility and mobile optimization to broaden audience reach and improve user experience.

Technical notes

Notes

The website is hosted on AWS Cloudfront CDN and uses Webnode CMS, which provides a stable and scalable infrastructure. The tech stack includes modern JavaScript libraries and tracking tools like Google Tag Manager and Facebook Pixel. Performance is optimized with CDN usage and responsive design. The site uses multiple CSS stylesheets and lazy loading for images, contributing to fast load times. However, there is room for improvement in accessibility features and security headers. The multilingual setup is well implemented, supporting Czech, English, Spanish, and Croatian languages. Overall, the technical implementation is solid with minor areas for enhancement.
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.
