FAQ
Common questions.
Everything you need to know before getting started.
Who is InterceptSuite for?
Anyone who needs to see what an application sends over the network: developers debugging client-server traffic, penetration testers and red teamers, malware analysts inspecting C2 communication, QA engineers, and IoT or database protocol researchers.
How does InterceptSuite differ from Burp Suite?
Burp Suite is designed for HTTP/HTTPS traffic only. InterceptSuite targets non-HTTP protocols - raw TCP, TLS, DTLS, STARTTLS, QUIC, and UDP - covering thick clients, IoT devices, databases, and any custom protocol.
What is ProxyBridge?
ProxyBridge is a lightweight system-wide SOCKS5 proxy companion for InterceptSuite. It routes all device traffic through InterceptSuite without requiring per-application proxy configuration.
Is there a free trial?
Yes. InterceptSuite offers a 7-day free trial with full feature access and no session time limit. No credit card required.
What operating systems are supported?
InterceptSuite and ProxyBridge both support Windows, macOS, and Linux.
How do I intercept TLS traffic?
Route your target application through the built-in SOCKS5 proxy, or use ProxyBridge for system-wide interception. InterceptSuite handles certificate generation and TLS termination automatically.
