Product Documentation

Welcome to the official LAN Lens product documentation. Here, you will find comprehensive guides, reference architectures, OS permission diagnostics, and troubleshooting blueprints to help you auditing local environments like a network security specialist.

Zero-Cloud Architecture

LAN Lens is fundamentally designed around **local-only processing**. We do not spin up network socket queries to third-party databases, nor do we cache your scanned nodes or passwords in the cloud. All sweeps are executed strictly from your machine, ensuring complete privacy compliance.
