About nono
nono is a Rust project for secure multiplexed execution paths for AI agents. It lives in AI security and privacy. It is built by the team that brought Sigstore. It aims to run agents with zero trust, zero setup, and zero latency.
About agentic_security
Agentic Security is an open source vulnerability scanner and AI red teaming kit for agent workflows and large language models. It lives in the Python AI security ecosystem and is distributed under the Apache 2.0 license. The project addresses the problem of testing LLM applications and agent systems against jailbreaks, fuzzing, and multimodal attacks. It gives developers, researchers, and security teams a local workflow for probing model endpoints, dataset driven attack vectors, and safety thresholds before deployment.
