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

Brno iD is a government-operated digital platform providing residents and visitors of Brno city with online access to a wide range of municipal services including public transport ticketing, waste tax payments, family vouchers, and cultural institution tickets. The platform serves a large user base exceeding 781,000 registered users, positioning it as the primary e-shop portal for city services in Brno. The website is professionally designed with consistent branding and clear navigation, supporting multiple service modules tailored to different public needs. Technically, the site leverages modern web technologies such as jQuery, Bootstrap, and Google reCAPTCHA, and is built on the PrestaShop CMS platform. HTTPS is enforced, ensuring secure communications. However, the absence of WHOIS registration data and lack of visible contact emails or phone numbers slightly reduce trust from a domain registration perspective. Privacy compliance is partially addressed with a comprehensive privacy policy available, but cookie consent mechanisms are missing. Security headers are not detected, indicating room for improvement in security hardening. Overall, the site is functional, secure, and trustworthy from a user perspective but would benefit from enhanced transparency and security practices.

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"

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

Brno iD operates as an essential government service platform in the transportation, tourism, and public services sectors. Its business model focuses on digital transformation of municipal services, enabling convenient online transactions and account management for citizens. The platform's competitive advantage lies in its integration of multiple city services into a single account system, fostering user retention and engagement. Revenue streams likely derive from service fees and ticket sales. The target audience includes Brno residents and tourists seeking easy access to city services. The partnership ecosystem includes the official city website and related service providers. Growth indicators include a high registered user base and continuous addition of service modules. Strategic observations suggest the platform is a critical digital asset for Brno city, with potential for expansion into additional municipal services and enhanced user experience features.

Security posture

The website demonstrates a moderate to strong security posture with mandatory HTTPS encryption and use of Google reCAPTCHA to protect forms from automated abuse. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The lack of published security policies, incident response contacts, or vulnerability disclosure programs indicates limited transparency in security governance. Compliance with GDPR is partially evident through the privacy policy, but cookie consent mechanisms are lacking. Incident response readiness and security culture indicators are not publicly visible. Overall, the site is secure for general use but would benefit from implementing additional security best practices and transparency measures.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  2. Add a cookie consent banner or mechanism to comply fully with GDPR and inform users about cookie usage.
  3. Publish a dedicated security policy and incident response information to improve transparency and user trust.
  4. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  5. Enhance contact information visibility by providing official company emails and phone numbers for support and security contacts.

Technical notes

Notes

The website is built on the PrestaShop CMS platform, utilizing modern JavaScript libraries such as jQuery 3.7.1 and Bootstrap for responsive design. Google Fonts and Google reCAPTCHA are integrated for typography and security respectively. The site loads multiple CSS and JS assets asynchronously, contributing to moderate performance. Mobile optimization is good with responsive layouts and viewport settings. Accessibility features are basic but present. SEO is supported by proper meta tags and structured navigation. Technical debt appears low with no deprecated libraries detected. Hosting provider details are not disclosed. Opportunities exist to improve performance by optimizing asset delivery and implementing advanced caching. Technical risks are minimal but could arise from missing security headers and incomplete privacy compliance.
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.
