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.

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

SAZKAmobil operates as an MVNO in the Czech telecommunications market, offering prepaid mobile services with a focus on simplicity and cost-effectiveness. Its competitive advantage lies in utilizing Vodafone's extensive 5G network coverage and providing rewards and promotions to customers. The business model centers on prepaid SIM sales, data packages, and number portability services. The website's multi-language support and extensive customer support resources indicate a strategy to attract diverse customer segments including expatriates and tourists. Partnerships with Vodafone and presence on major social media platforms enhance brand visibility and customer engagement. The company appears to be medium-sized with a solid market position in the Czech Republic's telecom sector.

Security posture

The website employs HTTPS with a presumably strong SSL configuration, ensuring encrypted communications. It integrates several third-party analytics and marketing scripts, which are common but require ongoing monitoring for vulnerabilities. No security headers were detected in the provided data, suggesting an area for improvement to mitigate risks such as clickjacking and cross-site scripting. No exposed sensitive information or vulnerable libraries were identified. The presence of a cookie consent mechanism and privacy policy indicates compliance with GDPR. Incident response and security policy details are not publicly available, which could be enhanced to improve transparency and readiness. Overall, the security posture is good but could benefit from implementing additional HTTP security headers and publishing incident response information.

Recommendations

  1. Implement and enforce HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a clear security policy and incident response plan accessible to users and partners.
  3. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  4. Enhance accessibility features to meet recognized standards and improve user inclusivity.
  5. Consider publishing WHOIS data or ensuring domain registration transparency to improve trust.

Technical notes

Notes

The website is built using modern JavaScript frameworks, specifically Nuxt.js (Vue.js), enabling server-side rendering and improved SEO. It uses Tealium for tag management, Hotjar for user behavior analytics, and Google Tag Manager for analytics deployment. The site is mobile-optimized with responsive design and preloads critical assets for performance. DNS and hosting details are not explicitly available, but the use of CDN-hosted assets suggests a distributed hosting approach. Performance is moderate, with room for optimization in accessibility and security headers. The technical stack supports a robust and scalable platform suitable for a telecommunications service provider.
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.
