Advanced Data Pilfering vs jwt-heartbreaker: 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. jwt-heartbreaker 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 AppSec engineers who routinely audit REST APIs will find jwt-heartbreaker indispensable for JWT validation testing inside Burp; it automates the tedious checks for unsigned tokens, weak secrets, and algorithm confusion that manual review misses. The 135 GitHub stars and active maintenance show real adoption among practitioners who integrate it into their standard Burp workflows rather than reaching for heavier, closed-source alternatives. Skip this if your threat model doesn't involve JWT-authenticated APIs or if you need post-exploitation JWT manipulation; jwt-heartbreaker focuses narrowly on the discovery and validation phase.
