Risk levelMedium

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

Oneplay is a Czech Republic-based online streaming service offering a wide range of entertainment including movies, series, sports, exclusive content, and live TV with replay and recording features. The website is professionally designed with good content relevance and targets Czech-speaking consumers interested in digital media consumption. The technical infrastructure leverages modern JavaScript frameworks and integrates third-party SDKs for privacy management and payment processing, indicating a mature digital presence. Security posture is moderate with HTTPS usage and privacy SDK integration, but lacks visible security headers and explicit security policies. The absence of WHOIS data and contact information reduces overall trustworthiness and compliance visibility. Strategic improvements in transparency, privacy policy publication, and security hardening are recommended to enhance user trust and regulatory 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.

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

8 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

    • 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

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

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

Oneplay operates in the media industry as a regional streaming platform in the Czech Republic. Its business model is subscription-based, focusing on delivering diverse content including films, series, and sports to a Czech audience. The company appears to maintain consistent branding and good content quality, positioning itself as a competitive player in the local streaming market. The use of advanced technical tools and integration with payment services suggests a focus on user experience and monetization. However, the lack of publicly available business registration details and contact information limits external validation of its corporate standing. The presence of a Twitter link indicates some social media engagement, but broader partnership or subsidiary relationships are not evident from the data.

Security posture

The website demonstrates a baseline security posture with enforced HTTPS and integration of a privacy SDK for consent management. However, the absence of detailed security headers, explicit security policies, and incident response contacts indicates room for improvement in security maturity. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of WHOIS transparency and missing contact channels for security incidents could pose risks in trust and accountability. Enhancing security headers, implementing robust form protections, and publishing clear security and incident response policies would strengthen the overall security posture and compliance with GDPR and other regulations.

Recommendations

  1. Implement comprehensive privacy and cookie policies accessible from the website footer or main navigation.
  2. Publish clear contact information including company emails and phone numbers to improve business credibility and user trust.
  3. Add and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Establish and disclose an incident response policy with dedicated security contact channels.
  5. Regularly audit and update third-party libraries and SDKs to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses modern JavaScript frameworks, likely Vue.js, and integrates third-party SDKs such as Google Tag Manager and Adyen Checkout for analytics and payment processing. The presence of Splide.js indicates use of carousels for UI elements. The site is mobile optimized with responsive design and uses structured data (JSON-LD) for SEO enhancement. Performance is moderate, with asynchronous loading of scripts and preconnect hints to external domains. However, no CMS or hosting provider information was detected. Accessibility features are basic, and SEO is supported by meta tags and Open Graph data. Technical improvements could focus on enhancing accessibility, optimizing performance further, and ensuring all scripts are up-to-date and secure.
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.
