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 operates in the technology sector focusing on cybersecurity software and services. Their business model centers on software sales and subscription services targeting both individual consumers and corporate clients. The company leverages its long history and German engineering reputation to maintain a competitive advantage. Revenue streams likely include product licenses, renewals, and managed security services. The target customer segments include private users, small to medium enterprises, and larger organizations requiring endpoint and mobile security. The company maintains a partnership ecosystem evident from partner portals and regional sites. Growth indicators include continuous product updates, international presence, and active content marketing via blogs and webinars.

Security posture

The website exhibits a mature security posture with enforced HTTPS, GDPR-compliant cookie consent, and no visible sensitive data leaks. However, it lacks some advanced security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate certain attack vectors. Incident response contact details and a security.txt file are absent, limiting transparency for vulnerability reporting. The presence of recognized certifications and awards supports trust in their security capabilities. Overall, the security maturity is good but could be enhanced by publishing explicit security policies and improving header configurations.

Recommendations

  1. Implement and publish a dedicated security policy page detailing security practices and compliance.
  2. Add and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide explicit incident response contact information, including security@ or abuse@ email addresses.
  4. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  5. Enhance website accessibility features to improve compliance with WCAG standards.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust and enterprise-grade content management system. It uses modern JavaScript libraries and integrates third-party services for cookie consent and analytics. The site is mobile-optimized and structured with semantic HTML and meta tags supporting SEO. Performance is moderate, with room for optimization in loading speed and accessibility. Hosting details are not explicit but the presence of multiple CDN and consent manager domains indicates a distributed infrastructure. Technical risks are minimal, with no outdated or vulnerable libraries detected in the provided HTML content.
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.
