About

Codex Security is an AI-powered application security agent developed by OpenAI to help teams detect and fix vulnerabilities in software systems. The tool analyzes code repositories to understand the structure, architecture, and potential risk areas within a project. Using this context, it identifies complex security issues that traditional scanning tools might overlook. Codex Security prioritizes vulnerabilities based on their real-world impact, helping security teams focus on the most critical threats. The system also validates findings through sandboxed testing environments to reduce false positives and improve accuracy. Once vulnerabilities are confirmed, it proposes patches and remediation steps that align with the system’s existing behavior. By combining AI reasoning with automated validation, Codex Security helps development teams ship more secure code faster.

About

SimSpace provides a realistic cyber range and AI proving ground for validating, operationalizing, and building AI agents alongside human operators inside a digital replica of a production environment. Security teams can continuously stress-test agentic and human defenses against realistic user behavior, attack emulation, and LLM-driven threats before they reach production. It reproduces actual infrastructure, tools, data schemas, workflows, and playbooks so organizations can evaluate how agents behave under real operating conditions rather than relying on representative test environments. SimSpace assesses not only outcomes but also the complete trajectory of an agent’s behavior, including tool calls, escalation gates, and error recovery, helping identify agents that reach the right result for the wrong reasons. Validation can run continuously through headless, API-driven workflows designed for CI/CD environments as models and playbooks evolve.
