Backend integration, mobile debugging, security testing, load testing, protocol development, capture and decryption, and more — each job has its own solution
The app connects directly and skips the proxy, HTTPS is a wall of ciphertext, and front-end and back-end blame each other over one field, comparing requests by eye.
NIC-capture the direct traffic → decrypt automatically → diff two requests line by line to tell a data problem from a display one → generate code and paste it back into the project.
The app’s HTTPS is all ciphertext, a pinned cert blocks the body, and installing a cert keeps failing on iOS and recent Android.
Read plaintext from inside the app → iOS without a jailbreak, Android without a cert install → pinning doesn’t block it, the body is right there.
You’re integrating a third-party service with no API docs, unsure what to send or what comes back.
Capture the real traffic and decrypt it → read every field of the request and response → turn it into an OpenAPI spec and generate client code.
A device or service speaks a private binary protocol, and the capture is a wall of noise with no visible frame structure.
Write a short script to declare the framing → the private protocol is restored to structured fields → check the implementation frame by frame.
You need to see whether an app or client sends sensitive data in the clear, and whether the server accepts tampered parameters.
Intercept in the middle → change the request at a breakpoint and watch the server respond → read the host dossier for cert grade and tech stack, and map the risks.
All you have is one domain or IP, too little to know what services sit behind it.
Host dossier for ownership, an A–F cert grade and tech stack → subdomain discovery plus port scanning → fill out the asset surface.
Capture and load testing are two separate tools, and signed or timestamped APIs can’t be tested directly.
Right-click “Load-test this request” → signatures and timestamps recompute from dynamic values so it runs directly → honest tail-latency numbers.
You want to see how the app behaves on 2G, packet loss or high latency, but that environment is a pain to set up.
One-click weak-network presets → add latency, cap bandwidth, drop packets → see how the app really reacts on a bad connection.
Timeouts, packet loss, speed that comes and goes, and the logs don’t show where the problem is.
Read handshakes and retransmissions packet by packet → the protocol tree pinpoints DNS, TCP or the app layer → the connection table shows which process connects where.
A system app or a stubborn one won’t let the proxy in and blocks injection, leaving only ciphertext on the wire.
System-level capture reads plaintext from below → or capture just one target program on its own → what other tools can’t reach, it can.
