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

Star Taxi Liberec is a local taxi service provider operating in the Liberec region of the Czech Republic. The company offers 24/7 taxi services with features such as online ordering, a mobile app supporting online payments, and a VIP loyalty program that rewards frequent customers with vouchers. The website is professionally designed using WordPress and Elementor, with SEO optimizations and multilingual support. Contact information is clearly presented, including phone numbers, email, and physical addresses, enhancing business credibility. However, the WHOIS data for the domain is missing, which raises some concerns about domain registration transparency but does not detract from the apparent legitimacy of the business itself.

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

10 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. 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"

    • 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

The company targets local residents and visitors needing reliable taxi transportation in Liberec. Its business model focuses on direct customer engagement through online platforms and incentivizes loyalty via a points and voucher system. Partnerships with external services for online ordering and payment processing indicate a collaborative ecosystem. The business appears small but well-positioned within its local market, leveraging digital tools to enhance customer experience and operational efficiency.

Security posture

The website uses HTTPS and implements a cookie consent mechanism compliant with GDPR principles, indicating awareness of privacy regulations. However, no advanced security headers were detected, and no incident response or security policy information is provided. The absence of WHOIS data reduces domain trustworthiness. There are no visible vulnerabilities or exposed sensitive data, but security posture could be improved by adding security headers and publishing incident response contacts.

Recommendations

  1. Add and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a clear privacy policy page to complement the cookie consent and improve GDPR compliance transparency.
  3. Include incident response and security contact information to facilitate vulnerability reporting and enhance trust.
  4. Investigate and resolve the missing WHOIS data to improve domain registration transparency and legitimacy.
  5. Regularly update all CMS components and plugins to mitigate potential security risks.

Technical notes

Notes

The website is built on WordPress with Elementor page builder and uses modern plugins like Yoast SEO and TranslatePress for multilingual support. It integrates Google Tag Manager for analytics and The Pay service for payment processing. The site is mobile-optimized and loads with moderate performance. The technical stack is standard for small to medium business websites, with room for improvement in security hardening and performance optimization.
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.
