Execution Enforcer: The Autonomous Protocol Agent

Sentinel is an autonomous compliance agent designed to bridge the gap between static intention and active execution in modern DevOps environments. Traditional logging tools are completely passive; they record system data but fail to remediate configuration errors or enforce security baselines in real-time. Sentinel changes this dynamic by scanning active infrastructure and automatically evaluating it against rigorous enterprise standards like SOC2, ISO 27001, and NIST SP 800-53.The application is engineered as a highly scalable, serverless cloud gateway. The backend reasoning engine taps directly into the Gemini 3 Flash Preview framework via a project-bound cloud connection, which allows it to process up to one million tokens of system metadata with deep evaluation logic and a rapid round-trip latency of just 1.1 seconds. The user interface features a custom obsidian-and-gold theme that uses a native browser DOM-parsing engine to instantly map the incoming structured JSON cloud payloads into clear, readable risk-assessment cards and status badges. The entire stack is containerized and deployed live on Google Cloud Run.During an evaluation cycle, Sentinel runs a multi-dimensional audit across critical infrastructure layers. It tracks identity management to prevent over-provisioned admin accounts, audits terminal-level CLI and SSH connections for multi-factor authentication loops, validates AES-256 encryption at rest, and checks node-to-node mTLS transit paths. It also flags vulnerabilities like static cryptographic salts on sensitive data and monitors centralized SIEM log tracking alongside backup disaster recovery drill timelines.Moving forward, our roadmap includes implementing native Model Context Protocol (MCP) tool bindings for autonomous hotfixes, as well as downstream webhooks to auto-generate urgent tracking tickets inside Jira or GitHub Issues the moment a non-compliant flag is triggered.
