Vyrox-proxy is a small Rust service that acts as the execution boundary for automated response actions in Vyrox's AI SOC analyst platform. It receives signed action requests authenticated via HMAC-SHA256, applies rate limiting, and logs all actions in an append-only audit log. The proxy is fail-closed by default, running in dry-run mode until explicitly enabled to perform live EDR API calls. The open-source release aims to provide transparency and allow CISOs to audit the exact code that can affect endpoint security controls. The project is alpha-stage, with a focus on memory safety and predictable runtime behavior. The vendor requests security community input to improve the threat model and implementation.

If improperly implemented or configured, this proxy could disrupt production workloads by executing incorrect or maliciously crafted commands such as isolating critical hosts or killing essential processes. However, the fail-closed default mode and multiple security controls (HMAC authentication, rate limiting, audit logging) reduce the risk of accidental or unauthorized actions. No known exploits or active attacks have been reported. The open-source nature allows for independent security review, potentially increasing trust and reducing risk over time.

This component is currently in alpha and designed to be fail-closed by default (dry run mode enabled). Users should keep DRY_RUN enabled until thorough testing and security review are completed. The vendor encourages security teams to audit the code, test the proxy in controlled environments, and provide feedback on the threat model. Proper management of the shared HMAC secret and monitoring of audit logs are essential. Since this is an open-source project without an official patch or advisory, users should track the repository for updates and improvements.
