Tools & Infrastructure

Technology Stack

Our technical infrastructure for digital forensics, evidence capture, AI-powered correlation, WORM-compliant storage, and data anonymization. Open-source where possible, enterprise-grade where required.

Infrastructure Philosophy

We build evidence capture and preservation systems using a combination of open-source tools and enterprise platforms. Our stack prioritizes immutability (WORM storage), verifiability (cryptographic hashing), AI-powered correlation (LLMs and graph analysis), and privacy compliance (automated PII redaction).
