Why Use Combat-Guard?

Raspberry Pi Security Appliance

Transform a low-power Raspberry Pi into a real-time LAN threat monitor. Capture SPAN switch traffic, analyze Suricata alerts, and inspect suspicious activity locally.

Suricata Alert Engine

Collects and parses live intrusion alerts, signature matches, and threat feeds directly from Suricata IDS/IPS.

Dual Network Interfaces

eth0 serves the web interface at http://PI-IP:8080 while eth1 passively monitors mirrored switch traffic.

Instant Threat Identification

Identify rogue devices, port scans, critical severity exploits, and noisy source IPs in real time.

100% Local Sovereignty

All logs stay encrypted on your Pi's local storage. Zero cloud telemetry, zero external leaks.

Core Principles

Why ByteApp?

We believe that user telemetry, centralized cloud sync, and algorithmic nudges have corrupted modern utilities. Your health history, financial tracking, and smart home details should never sit on someone else's server.

Every tool in the ByteApp ecosystem runs entirely on your local CPU. Data remains encrypted on your local drive, rendering cloud leaks and telemetry collection physically impossible.

Offline First

No internet connection required for app operations. Perfect for traveling or emergency access.

Encrypted Locally

AES-256 database protection prevents physical intruders from extracting your data.

Telemetry Free

No tracking events, no usage reports, no cookies. Just software that executes your tasks.
