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

CITY CARD is a regional cultural discount card service focused on providing residents and visitors of Frankfurt and the Rhein-Main area with exclusive 2for1 offers and discounts across events, leisure, gastronomy, and shopping. The website presents a professional and content-rich platform with a clear focus on cultural and lifestyle benefits, targeting a general audience interested in local cultural engagement. The business model revolves around membership and promotional partnerships with local vendors and event organizers, positioning CITY CARD as a key player in the regional cultural discount market. Technically, the website employs a moderate technology stack including jQuery, Google Tag Manager, and Usercentrics for consent management. The site is served over HTTPS with basic privacy compliance mechanisms in place, including a privacy policy and cookie consent banner. However, there is room for improvement in security headers and mobile optimization. The site features extensive image-based animations to promote offers, enhancing user engagement but potentially impacting performance. From a security perspective, the site demonstrates good practices such as HTTPS enforcement and default denial of tracking until user consent. Google Analytics is integrated but disabled by default, respecting privacy regulations. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms suggests a moderate security maturity level. Overall, CITY CARD's website is trustworthy, professionally maintained, and compliant with GDPR requirements. Strategic enhancements in security headers, mobile responsiveness, and explicit policy disclosures would further strengthen its security posture and user trust.

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.

Priority findings

5 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 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';…

  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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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.

Business context

Business profile

CITY CARD operates in the hospitality and retail sectors, offering a cultural discount card that provides value-added services to customers in the Frankfurt and Rhein-Main region. Its competitive advantage lies in a broad network of partners offering exclusive 2for1 deals and discounts, appealing to culture enthusiasts and local consumers. The business model is based on membership fees and partnerships with local businesses. The website indicates a small-sized enterprise with a regional focus and a consistent branding approach. The partnership ecosystem is implied but not explicitly detailed. Growth indicators include monthly addition of new offers and a focus on digital engagement through the website and consent-managed analytics. The company leverages digital marketing tools such as Google Tag Manager and Usercentrics to manage user consent and track engagement while maintaining privacy compliance. The absence of direct contact emails or phone numbers on the main page suggests a preference for contact forms, possibly to streamline inquiries. No parent or subsidiary companies are indicated, suggesting an independent operation.

Security posture

The security posture of CITY CARD's website is moderate. HTTPS is properly implemented, ensuring encrypted communication. The use of Usercentrics for consent management and Google Consent Mode with default denial of ad and analytics storage reflects a privacy-conscious approach. However, the lack of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security hardening. No direct evidence of vulnerable libraries or exposed sensitive data was found. The site does not provide explicit security policies or incident response contacts, which are important for transparency and readiness. The integration of Google Analytics is handled responsibly with opt-out mechanisms and default disablement until consent. The site does not appear to be behind a WAF or present any blocking challenges, indicating normal accessibility. Recommendations include adding security headers, publishing incident response and vulnerability disclosure policies, and enhancing mobile and accessibility features to improve security and compliance maturity.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  2. Publish explicit terms of service, security policy, and vulnerability disclosure pages to enhance transparency.
  3. Add incident response contact information such as security@ or abuse@ email addresses.
  4. Improve mobile optimization and accessibility to enhance user experience and compliance.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a traditional web stack with jQuery and custom JavaScript for animations and user interactions. Google Tag Manager and Usercentrics are integrated for analytics and consent management, reflecting a modern approach to privacy compliance. The site is served over HTTPS, but no CMS or hosting provider details are evident from the HTML. Performance is moderate due to extensive image animations, which may impact load times. SEO is basic with meta tags and structured navigation but lacks advanced structured data like JSON-LD or Open Graph tags. Accessibility features are minimal, and mobile optimization is basic, indicating opportunities for modernization and technical improvements.
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.
