Humanbound
Adversarial testing, a runtime firewall and monitoring for AI agents and chatbots, with an open-source engine
Humanbound tests AI agents and chatbots with adversarial attacks before release, then guards and monitors them in production. Tests run single-turn, multi-turn and agentic attacks (prompt injection, jailbreaks, data exfiltration, tool abuse) and tag findings to the OWASP LLM and Agentic Top 10.
The testing engine, CLI and firewall are open source under Apache-2.0 and run locally with no account. The firewall has four tiers, from input sanitization up to an LLM judge.
The hosted platform adds monitoring and team seats. The Community plan is €0; Team is €349/month.
