About

Antaeus is a semantic policy engine for developers who need to evaluate human-written rules about language, context, intent, or exceptions. Its open-source Go core and command-line interface load YAML or JSON policy artifacts, validate them against versioned schemas, and run named regression cases. The evaluator returns explicit allow, review, deny, or failure outcomes with policy identity and decision evidence, leaving authentication, authorization, and consequential actions to the application. Developers can run a deterministic, credential-free local workflow or use the experimental hosted dashboard and API to manage policies and evaluate inputs. An experimental OpenAI evaluator is also available. Antaeus is an early-stage project; hosted service capacity is shared and has no production SLA.

About

Harden AIF is an agent endpoint security platform for AI coding agents. It evaluates supported agent tool calls before execution using the developer’s intent, session context, organisational policy, and the effect of the proposed action. Harden helps protect against destructive commands, unauthorized access, unintended data transfers, secret exposure, privilege misuse, and other unsafe agent actions. Legitimate actions can proceed normally, sensitive data in supported flows can be safely redacted, and actions that fall outside the developer’s intent or authority are blocked before execution. Harden works across popular coding agents and agentic development tools including Claude Code, Codex, Cursor, Antigravity CLI, Kiro, Hermes, and OpenClaw, providing a consistent security layer across the agent ecosystem.
