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

cantamen GmbH is a German company specializing in software and services for the shared mobility sector, including carsharing, bikesharing, and corporate mobility solutions. With over 20 years of experience, they provide a comprehensive suite of products such as booking and management tools, customer apps, billing, and fleet management, supported by 24/7 customer and technical service. Their market position is that of an established, trusted provider in the shared mobility technology space, targeting B2B clients like fleet operators and mobility service providers. Technically, the website is built with standard web technologies (HTML5, CSS3, JavaScript) and serves content over HTTPS with good mobile optimization and moderate performance. However, it lacks advanced SEO and accessibility features and does not implement visible security headers or cookie consent mechanisms, which are areas for improvement. From a security perspective, the site uses HTTPS and does not expose sensitive data or vulnerable libraries in the provided content. The absence of security headers and incident response contacts suggests room for enhancing security posture and compliance. No WAF or blocking mechanisms were detected, indicating full accessibility. Overall, the website presents a professional and trustworthy business front with solid content quality and business credibility. Strategic improvements in privacy compliance, security headers, and contact transparency would further strengthen their digital maturity and security posture.

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

7 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 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

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

cantamen GmbH operates in the transportation and technology sectors, focusing on shared mobility software solutions. Their competitive advantage lies in their full-service approach, combining software, hardware, and customer support with long-standing industry experience. The business model is B2B, serving carsharing providers, corporate fleets, and mobility platforms. Revenue streams likely include software licensing, hardware sales, consulting, and support services. The company participates in research projects and networks, indicating active engagement in innovation and industry collaboration. Growth potential exists in expanding MaaS offerings and integrating new mobility services. The lack of visible social media and limited online contact info suggests a focus on direct business relationships rather than broad consumer marketing.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible vulnerabilities in the analyzed content. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces defense-in-depth. No incident response or abuse contact information is provided, which is a compliance and operational gap. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism detected. The site does not expose sensitive data or use vulnerable libraries in the visible scripts. Overall, the security posture is adequate but could be improved by implementing recommended headers, enhancing privacy controls, and publishing incident response contacts.

Recommendations

  1. Implement standard security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to improve protection against common web attacks.
  2. Add a cookie consent banner or mechanism to comply fully with GDPR cookie requirements.
  3. Publish clear contact information for security incidents and abuse reporting to enhance incident response readiness.
  4. Enhance accessibility and SEO features to improve user experience and search engine visibility.
  5. Consider adding structured data (JSON-LD) and Open Graph tags to improve content sharing and SEO.

Technical notes

Notes

The website uses a clean, modern HTML5 structure with external CSS and JavaScript assets hosted on the same domain. No CMS or third-party frameworks were detected in the provided content. The site is mobile optimized with responsive images and viewport meta tags. Performance is moderate, with no obvious heavy scripts or external dependencies. The lack of advanced SEO tags and structured data indicates potential for technical SEO improvements. No analytics or tracking scripts were found, suggesting minimal user tracking. The hosting provider and infrastructure details are not disclosed. Overall, the technical implementation is solid but basic, with opportunities for modernization and enhanced SEO and accessibility.
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.
