Summary	Australian 'autonomous system of agents' for product security that covers code, secrets, API pentesting and exploit validation. It proves findings with reproducible evidence, scores them against the customer's assets, writes merge-ready fix PRs routed to code owners, and runs remediation campaigns through Jira and Slack until merge, with the customer keeping final merge approval.	OX's autonomous security agent connects to AI coding tools and IDEs to catch and correct risky or malicious code and dependencies before code is generated and to govern which coding agents, MCP servers and skills are used; the OX Agentic Pentester discovers, exploits and validates application vulnerabilities and maps them back to the source code.
