SECURITY ANALYTICS WITHOUT THE NETWORK.

ZERO DEPENDENCIES<200ms PIPELINEAIR-GAPPED

The Challenge

Security analytics in air-gapped environments is extremely difficult without heavy runtime dependencies like ELK or Splunk.

The Solution

Single-binary offline security auditor with built-in statistical detection engines (Z-Score & Markov Chains) — no runtime dependencies required.

System Overview

OSA (Offline Security Auditor) is an air-gapped security analytics engine compiled as a single Go binary. It performs log ingestion and statistical anomaly detection without any runtime dependencies, making it ideal for isolated secure zones. It supports real-time streaming and historical batch analysis. Detection engines include Z-Score analysis for statistical outliers and Markov Chain models for behavioral sequential deviations. It reduced false positives by 38% in tests compared to baseline methods.

Evolving into a zero-config, Kubernetes-native security engine, OSA (also known internally as LogShield) automatically detects and masks sensitive secrets (API keys, passwords, PII) in application logs before they are written to disk or shipped to log aggregators. It operates natively inside your cluster without compromising performance.
