Security score

78/100

Risk levelLow

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

CodeWeavers is a technology company specializing in software that enables users to run Microsoft Windows applications on Mac and Linux platforms without the need for a Windows license or virtual machines. Their flagship product, CrossOver, targets Mac and Linux users seeking seamless Windows compatibility. The website presents a professional and modern interface, leveraging technologies such as jQuery, Bootstrap, and Font Awesome, and integrates Google Analytics for user tracking. However, the absence of WHOIS data and lack of visible privacy and cookie policies indicate areas for improvement in transparency and compliance. Security posture is moderate, with no detected security headers and unknown SSL configuration, suggesting potential vulnerabilities. Overall, the website is functional and trustworthy from a content perspective but would benefit from enhanced security and privacy measures to improve user trust and compliance.

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.

    • 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

CodeWeavers operates in a niche market providing compatibility solutions for Windows applications on alternative operating systems. Their business model revolves around software licensing and sales, targeting a medium-sized audience of Mac and Linux users. The company maintains consistent branding and leverages social media verification signals. The lack of detailed WHOIS and contact information limits external verification of business legitimacy. The use of modern web technologies and analytics indicates a digitally mature organization, though privacy compliance and security policies require strengthening. No partnerships or subsidiaries were identified from the provided data.

Security posture

The website employs HTTPS and modern frontend libraries but lacks explicit security headers such as Content-Security-Policy or X-Frame-Options, which are critical for mitigating common web vulnerabilities. No exposed sensitive data or vulnerable libraries were detected in the provided content. The absence of privacy and cookie policies suggests potential compliance gaps with GDPR and other data protection regulations. Incident response and vulnerability disclosure mechanisms are not evident, indicating limited readiness for security incidents. Overall, the security posture is moderate but requires enhancements in policy transparency and technical safeguards.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  3. Publish incident response and vulnerability disclosure information to improve transparency and readiness.
  4. Obtain and display verified WHOIS and business registration information to enhance trustworthiness.
  5. Regularly audit and update SSL/TLS configurations and frontend libraries to maintain security hygiene.

Technical notes

Notes

The website uses a modern technology stack including jQuery, Bootstrap, and Font Awesome, ensuring responsive design and good user experience across devices. Google Tag Manager and Analytics are integrated for tracking user behavior. The site loads external CSS and JS resources from trusted CDNs with integrity checks, indicating attention to security in resource loading. However, no CMS or hosting provider information was identified. Performance is moderate with room for optimization. Accessibility features are basic, and SEO is supported by proper meta tags and Open Graph data. Technical debt appears low but could be improved by adding accessibility enhancements and security headers.
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.
