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

CAS Software AG is a German market leader specializing in CRM and CPQ software solutions tailored for small to medium-sized enterprises and larger organizations. Their offerings include adaptive CRM systems integrated with AI assistants (AIA®) to enhance customer centricity and streamline business processes. The company emphasizes innovation, digital sovereignty, and customer-focused solutions, serving over 550,000 users across more than 35,000 organizations. The website reflects a mature digital presence with multilingual support and comprehensive service information. Technically, the website is built on WordPress with modern JavaScript frameworks such as Vue.js and Video.js, supported by Matomo analytics and Leadinfo tracking. The site is mobile-optimized, accessible, and SEO-friendly, though performance is moderate. Security posture is strong with HTTPS enforced and no exposed sensitive data, but could benefit from enhanced security headers and explicit cookie consent mechanisms. Overall, CAS Software AG demonstrates a high level of professionalism and trustworthiness, with clear contact channels and customer testimonials. However, the absence of a dedicated security policy page, incident response contacts, and vulnerability disclosure mechanisms suggests areas for improvement in security transparency and compliance. Strategically, the company should focus on enhancing privacy compliance by implementing cookie consent banners, publishing security policies, and establishing incident response contacts to strengthen trust and regulatory adherence.

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

4 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';…

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.

Business context

Business profile

CAS Software AG holds a strong position in the German CRM software market, targeting SMEs and larger enterprises with tailored CRM and CPQ solutions enhanced by AI capabilities. Their business model revolves around software licensing, consulting, and support services. The company leverages partnerships and a broad ecosystem, including event collaborations and partner portals, to expand reach and customer engagement. Growth indicators include continuous product innovation, awards, and a large user base. The company maintains a consistent brand image and professional digital presence, supporting its market leadership claims.

Security posture

The website exhibits a mature security posture with HTTPS enforced and no visible exposure of sensitive data. Use of Matomo analytics with cookie consent requirements indicates attention to privacy. However, the lack of explicit Content-Security-Policy headers and absence of a security policy or incident response contact information are gaps. No security.txt or vulnerability disclosure pages were found, limiting transparency. The site uses third-party scripts which should be regularly audited. Overall, security practices are good but could be improved with formalized policies and enhanced header configurations.

Recommendations

  1. Implement a comprehensive cookie consent mechanism to ensure GDPR compliance.
  2. Publish a dedicated security policy page outlining frameworks and practices.
  3. Add a security.txt file and incident response contact information for vulnerability reporting.
  4. Enhance HTTP security headers, including Content-Security-Policy and X-Content-Type-Options.
  5. Regularly audit third-party scripts and tracking tools for vulnerabilities and privacy compliance.

Technical notes

Notes

The website is powered by WordPress CMS with a modern tech stack including Vue.js, Video.js, and Swiper.js for interactive UI components. It uses Matomo for analytics and Leadinfo for visitor tracking, both requiring cookie consent. The site is mobile-optimized and accessible with good SEO practices. Performance is moderate, possibly due to multiple external scripts and large media assets. Hosting details are not explicit but the use of company-specific name servers suggests dedicated infrastructure. Technical risks include reliance on multiple third-party scripts and partial security header implementation.
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.
