Adversa AI launches a runtime security platform that blocks risky coding-agent action chains

Generally available Oct 29, it watches what Claude Code, Codex, Copilot and Cursor do through an LLM/MCP gateway, harness hooks and an endpoint sensor, links the steps into a behavior graph, and blocks a dangerous chain (say, a malicious skill reading secrets and then exfiltrating them) before the last step runs. Teams can start in observe-only mode, and Adversa reports a 0.2 ms median blocking decision at one financial-institution deployment (product page).
