Welcome to InterceptSuite Documentation
InterceptSuite v2.1.0: Advanced SOCKS5 proxy for TLS, DTLS and QUIC interception with Python extension support. Perfect for security professionals, developers, system administrators, and network engineers who need powerful network analysis capabilities.
About InterceptSuite
InterceptSuite is a high-performance SOCKS5 proxy that sits between your applications and the network. It intercepts, decrypts, and allows you to inspect or modify traffic in real-time, including TLS-encrypted connections, without modifying the applications themselves.
Key Features
- TLS Interception: Advanced TLS traffic analysis and manipulation
- DTLS Interception: Datagram TLS traffic analysis and manipulation
- QUIC / HTTP/3 Interception: Intercept QUIC traffic, with every stream relayed
- TCP/UDP Interception: Raw TCP and UDP traffic interception and analysis
- Interception Rules: Hold only the packets you want, per direction, by host, port, protocol, size, payload or scope
- Replay: Build and send your own packets over TCP, TLS, STARTTLS, UDP, DTLS and QUIC
- Scope: Define your targets and filter history, interception and extensions by them
- TLS Pass-Through: Relay certificate-pinned targets without decrypting them
- Traffic Redirect (Windows): Send selected applications through the proxy without changing them, built into the app
- Install Certificate: One-click install of the CA certificate into the Windows, macOS or Linux trust store (Proxy Settings)
- Hex Editor: Edit packet bytes in hex in Intercept and Replay
- AI Access (MCP): Let an AI agent work with the app (off by default)
- Universal TLS Upgrade Detection: Automatic detection of protocol upgrades to TLS
- Python Extension Support: Decode and edit protocols with custom Python 3 scripts, in History, Intercept and Replay
- SOCKS5 Proxy: High-performance proxy server with full SOCKS5 protocol support
- Cross-Platform: Windows, macOS, and Linux support (Traffic Redirect is Windows only for now)
- Project Management: Organize your work with project files
- PCAP Export: Export captured traffic for external analysis in Wireshark
