SSL/TLS-capable cybersecurity proxy

ARGUS

ARGUS is an interactive cybersecurity proxy for inspecting, capturing, replaying, and modifying HTTP/1, HTTP/2, WebSocket, TCP, UDP, and DNS traffic. It keeps the mature proxy engine and workflows developers expect while presenting a clean, modern interface for day-to-day traffic analysis.

Proxy workflow

Inspect Decode requests, frames, and packets.

Modify Change traffic before replay.

Replay Repeat flows from CLI or UI.

Built for traffic work that gets real.

ARGUS gives security engineers, developers, and testers the sharp tools they need without burying core workflows under noise.

Modern capture surface

Inspect encrypted and plaintext application traffic across browser, service, and command-line workflows.

HTTP/1 HTTP/2 WebSocket SSL/TLS

Replay and mutation

Capture once, investigate deeply, modify requests, and replay flows through the interface or command-line tooling.

TCP UDP DNS Raw streams

Automation continuity

Compatibility entry points remain available so existing scripts and operational workflows can continue using familiar commands.

Why ARGUS

Named for Argus Panoptes.

ARGUS takes its name from Argus Panoptes, the many-eyed watcher from Greek mythology. The reference fits a proxy built to observe traffic from every angle: requests, responses, frames, streams, DNS lookups, raw packets, replay paths, and the small details that reveal what a system is really doing.

The name is a reminder of the product's job: keep watch with precision, make hidden network behavior visible, and give engineers a calm command center for deciding what to inspect, modify, replay, or preserve.
