InterceptSuite
A TLS MITM proxy for Non-HTTP traffic, with support for TLS upgrades
...It goes beyond HTTP‑focused tools like Burp Suite and ZAP by providing universal TLS interception—including STARTTLS and non‑HTTP protocols—offering deep visibility and control for security testing and debugging. InterceptSuite bridges this gap by providing a universal TLS interception engine that works with any protocol, giving security researchers the tools they need to analyze, understand, and test encrypted communications effectively. With Python extension support, users can add custom protocol dissection capabilities tailored to their specific needs.
