Sentinel Threat Monitor

Looking where others don’t...

Web / MVC

Autonomous threat intake and pattern analysis across application logs, system signals, and user activity.
Built for rapid denial, forensic traceability, and deterministic policy enforcement within controlled environments.

Systems Daemon

Sentinel is a lightweight, deterministic, host-based intrusion prevention and policy enforcement daemon for controlled Linux systems. It operates without external dependencies, enforcing expected behavior at the file and execution level for mission-assurance use cases.

• Host-based intrusion prevention (file + execution enforcement)
• Deterministic policy control (allow / block / trust)
• Real-time detection and containment of unauthorized activity
• Local forensic logging with persistent state tracking
• Offline-capable operation (no external dependency required)
• Modular deployment: Web, IPS, and HIPS implementations
• API-enabled web intelligence integration

How It Works

Sentinel operates as a deterministic enforcement layer at the host level. It continuously evaluates system state against defined policy and takes immediate action when deviations occur.

Operational Flow

[Sentinel Detection Layer]

[Policy Engine]
  - allow
  - block
  - trust

[Action Engine]
  - quarantine file
  - log event
  - terminate process (optional)

Sentinel does not rely on external threat intelligence or signature updates. Instead, it enforces expected system behavior, ensuring that only authorized operations are permitted within the environment.

• All actions are locally enforced and logged
• No dependency on external connectivity or cloud services
• Behavior-driven enforcement rather than signature-based detection
• Designed for predictable, controlled system environments
