Simbian develops a security platform that uses autonomous AI agents to support continuous operations in threat detection, response, and governance. The platform includes a SOC agent that triages alerts from sources such as SIEMs and XDRs by applying institutional knowledge and organizational playbooks. A threat hunting agent processes threat intelligence feeds and searches for indicators of compromise across environments. A governance, risk, and compliance agent manages security questionnaires and vendor assessments through a conversational interface to reduce response times. The system integrates with enterprise tools and unstructured data to enable low-supervision security workflows.

ENGINPILOT ensures that every operational decision obeys physical law before execution. It sits between human operators and physical machinery, between AI recommendations and actuator commands, between digital intent and physical consequence—enforcing the laws of physics with hardware certainty and cryptographic proof. What We Deliver ENGINPILOT reduces downtime and increases productivity by enforcing physics at the core of decision-making. It provides a structured, physics-governed decision process that transforms engineering actions into traceable, verifiable outcomes—preserving institutional knowledge and eliminating unsafe guesswork. The ENGINPILOT Ecosystem ENGINPILOT.AI — Physics AI kernel + execution authority ENGINgpt.AI — Intent validation and anomaly detection ENGINPILOT.COM — Governance, policy, and audit control ENGINPILOT.ARMY — Escalation management and cryptographic approval Why This Matters Organizations managing safety-critical assets need more than dashboards and alerts. They need operational decisions grounded in physical law. They need institutional governance that withstands regulatory scrutiny. They need intelligence that can be audited, verified, and trusted. We do not ask you to trust us. We ask you to verify us. When intelligence controls machines, physics must control intelligence.
