Advanced Data Pilfering vs ysoserial: Side-by-Side Comparison (2026)
Features, pricing, ratings, and pros & cons — compared head-to-head.
Advanced Data Pilfering is a commercial penetration testing tool by Horizon3.ai. ysoserial 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 and red teamers validating Java deserialization vulnerabilities need ysoserial for its breadth of gadget chains; with 8,501 GitHub stars and active community contributions, it remains the de facto standard for generating CVE-2015-6420 and related payloads across legacy and modern Java frameworks. The tool's strength lies in its ability to craft working exploits against unsafe ObjectInputStream implementations without requiring live target interaction during payload generation. Skip this if your scope is limited to .NET or Python applications, or if you need a guided UI; ysoserial is command-line native and demands familiarity with Java serialization mechanics.
