Advanced Data Pilfering vs Legion: 2026 Comparison
Advanced Data Pilfering is a commercial penetration testing tool by Horizon3.ai. Legion is a free penetration testing tool. Compare features, ratings, integrations, and community reviews side by side to find the best penetration testing fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise security teams that need to validate whether their defenses actually stop data exfiltration should run Advanced Data Pilfering; most pentesting tools test access, not what attackers do once inside. Horizon3.ai's autonomous approach maps high-value assets and simulates realistic data theft across cloud, Kubernetes, and on-premises environments, delivering the threat-informed validation that compliance frameworks like PCI DSS and NIS 2 increasingly demand. Skip this if your team wants a single platform covering vulnerability scanning, SIEM, and incident response; Advanced Data Pilfering is purpose-built for exfiltration testing and doesn't replace your broader detection stack.
Penetration testers running internal security assessments on smaller networks will benefit from Legion's automated reconnaissance pipeline, which compresses hours of manual scanning into minutes without licensing friction. The 1,052 GitHub stars and active open source community signal production-grade stability for teams already comfortable maintaining their own tools. Skip Legion if your organization needs commercial support, reporting that maps to compliance frameworks, or scanning at scale across hundreds of hosts; you'll spend more time patching gaps than testing.
