About
Kastra is the authorization layer for AI systems, deciding what agents, models, and AI tools are allowed to do before they do it. It sits in the execution path of every prompt, tool call, shell command, database operation, and API request, evaluates each action against deterministic, attribute-based policy, and returns an allow, deny, redact, or escalate decision in under a millisecond. Unlike monitoring products that observe AI after it acts, Kastra blocks unauthorized behavior before it reaches a tool, API, database, or production system. Its unified control plane combines a policy engine, edge decision points, integrations, and a tamper-evident evidence vault that signs every decision for audit and replay. Kastra Edge brings local enforcement to developer machines, protecting Claude Code, Cursor, Codex CLI, and other coding agents from destructive commands, secret exfiltration, unsafe file writes, and unauthorized tool use.

About
nono is an open source, kernel-enforced sandbox for AI coding agents and LLM workloads. Unlike policy-based guardrails that intercept and filter operations, nono uses OS security primitives — Landlock on Linux and Seatbelt on macOS — to make unauthorised operations structurally impossible at the syscall level.
Wrap any AI agent — Claude Code, OpenCode, OpenClaw, or any CLI process — with a single command. nono applies default-deny filesystem access, blocks destructive commands (rm, dd, chmod, sudo), isolates credentials and API keys, and cascades all restrictions to child processes. No escape mechanism exists once restrictions are applied.
Built-in profiles get you running in seconds. Secrets inject securely from the system keystore and are zeroised on exit. Audit logging, atomic rollbacks, and Sigstore-attested policy signing are on the roadmap.
Apache 2.0. From the creator of Sigstore.

Audience
Enterprise AI security teams that need to govern autonomous agents and block unauthorized actions before execution
|
Audience
Developers & AI power users — Anyone running Claude Code, Cursor, OpenCode, or other CLI-based AI coding agents on their local machine who wants to prevent agents from accessing credentials, deleting files, or touching paths outside the project directory. CISO, Security engineers & DevSecOps teams — Teams responsible for establishing safe agent usage policies across engineering organisations. nono provides kernel-enforced, auditable enforcement without requiring infrastructure changes. Platform & ML engineers — Engineering teams building or evaluating agentic AI workflows who need runtime isolation as part of their agent stack. Software companies adopting AI tooling — Organisations in software development, fintech, healthcare, and any regulated industry where developer workstations hold sensitive credentials, proprietary code, or compliance-relevant data that must not be accessible to autonomous agents. Open source contributors & researchers — Security researchers and OSS contributors working with or studying AI agent threat models, kernel sandboxing, and runtime security primitives.
