Quick Start on Windows

Get InterceptSuite running on Windows in under 5 minutes.

Step 1: Launch InterceptSuite

When you launch the InterceptSuite application on Windows, it automatically:

• Opens the SOCKS5 TCP proxy on 127.0.0.1:4444
• Opens the UDP relay port on 127.0.0.1:4445

You should see the application interface with both services running in the background and confirmed in the Proxy tab.

Step 2: Install the CA Certificate (Required)

If this is your first time installing InterceptSuite, or you are updating to a new version, you must install the CA certificate into your system for TLS interception to work.

Export the Certificate from InterceptSuite

1. In the InterceptSuite application, navigate to the Proxy tab.
2. Go to the Settings tab within the Proxy section.
3. In the Certificate Management section, click Export Certificate.
4. Select DER format.
5. Choose your preferred export directory and save the file.

Install the Certificate on Windows

1. Locate the exported certificate file (.cer or .der).
2. Double-click on the certificate file.
3. Click Install Certificate....
4. Select Local Machine (not Current User).
5. Choose Place all certificates in the following store.
6. Click Browse and select Trusted Root Certification Authorities.
7. Click Next and Finish.
8. Click Yes when prompted with a security warning.
9. You should see "The import was successful".

Step 3: Configure Your Application

Windows does not natively support SOCKS5 proxy in its system settings (Settings -> Network & Internet -> Proxy only exposes HTTP proxy).

Recommended: Use ProxyBridge for system-wide SOCKS5 support

1. Download ProxyBridge from interceptsuite.com/download/proxybridge.
2. Install and launch ProxyBridge.
3. Navigate to the proxy menu and select Proxy Settings.
4. Enter address: 127.0.0.1, port: 4444, type: SOCKS5, then save.
5. Navigate to the proxy menu and Proxy Rules.
6. Add a new rule for the application you want to intercept.

Direct Application Configuration

For apps that allow direct proxy configuration (for example, web browsers or specific clients), use:

• Proxy Host: 127.0.0.1
• Proxy Port: 4444
• Proxy Type: SOCKS5

Step 4: Start Intercepting

1. Configure your target application to use the SOCKS5 proxy.
2. Start making network requests from the application.
3. Monitor traffic in real-time through the InterceptSuite interface.
4. Analyze captured data using the built-in Proxy History and Intercept tools.

You are all set. Next, explore the Traffic Interception guide to learn how to intercept and modify packets in real-time.
