Digital Self Defense
Awareness Is Defense
Security begins with understanding.
Echo reveals what is exposed. Denshi reveals what occurred. Together they provide awareness outside and inside the perimeter.
Denshi Goshin Jutsu
See the Inside
Investigate event logs, persistence, sessions, findings, and hardening posture on Windows systems.
- Event logs
- Persistence
- Hardening posture
Two perspectives. One goal.
Outside Awareness. Inside Awareness. Complete Awareness.
The tools are two halves of one security strategy: external observation through Echo, and internal investigation through Denshi Goshin Jutsu.

About Mando
The Builder Behind The Tools
Mando builds security tools for operators who would rather understand a system than blindly trust a dashboard. The mission is simple: make the first questions easier to answer when something feels exposed, suspicious, or wrong.
Echo and Denshi Goshin Jutsu are built with the same discipline: see clearly, move deliberately, and leave the operator with evidence they can act on.

Builder of security-focused tools for discovery, investigation, and defense.
