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

G DATA CyberDefense AG is a well-established cybersecurity company with a history dating back to 1987, specializing in antivirus and internet security solutions for both individual consumers and enterprises. The company offers a broad portfolio including antivirus for Windows and Mac, internet security suites, mobile security for Android and iOS, VPN services, and security awareness training. The website is professionally designed, multilingual, and targets a European audience with a strong presence in France. Technically, the site runs on TYPO3 CMS and integrates modern consent management and analytics tools, reflecting a mature digital infrastructure. Security-wise, the site enforces HTTPS and uses consent mechanisms for privacy compliance, though explicit security headers and incident response contacts could be improved. Overall, the domain WHOIS data is unavailable, likely due to privacy protection, but the website's trust signals and certifications support its legitimacy.

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

    • 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

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

G DATA holds a strong market position as an innovator in cybersecurity, credited with developing the first antivirus software globally. Its business model revolves around software sales and subscription services, targeting both consumer and enterprise segments. The company leverages partnerships and certifications such as Microsoft Azure Certified and VB100 to enhance credibility. The website supports multiple European markets and languages, indicating a broad geographic reach. The presence of affiliate programs and partner portals suggests a well-developed ecosystem. Growth indicators include active blogs, news updates, and a career section, signaling ongoing business activity and expansion.

Security posture

The website demonstrates a solid security posture with enforced HTTPS, use of consent management for GDPR compliance, and no visible exposure of sensitive data. However, the absence of explicit security headers like Content-Security-Policy and lack of published incident response contacts or security policy pages represent areas for improvement. The site does provide a vulnerability disclosure page, indicating some level of security maturity. No vulnerabilities or suspicious domains were detected in the analysis. Overall, the security posture is good but could be enhanced by adopting additional best practices and transparency measures.

Recommendations

  1. Implement and publish comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to strengthen browser security.
  2. Create and make accessible a dedicated security policy page detailing security practices and compliance frameworks.
  3. Publish clear incident response contact information, including dedicated security or abuse email addresses.
  4. Add a security.txt file at the root domain to facilitate responsible vulnerability disclosure.
  5. Regularly review and audit third-party scripts and tracking tools to minimize potential security risks.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and enterprise-grade content management system, ensuring scalability and security. It uses modern JavaScript libraries and integrates consent management and analytics tools such as ConsentManager, Matomo, and Google Tag Manager. The site is mobile-optimized with good accessibility and SEO practices. Performance is moderate, with potential for optimization in loading speed. Hosting details are not explicitly available, but the presence of AFNIC WHOIS server and French domain suggests hosting in or near France. The technical stack is mature and well-maintained, supporting a professional online presence.
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.
