Secure, automate, and prove your GTP network.
A complete GTP testing & assurance platform from eFellows — a proxy for both the signalling and data path, the tools to run it, and a simulation engine that verifies every procedure and Information Element behaves exactly as specified.
No sales runaround. Talk to an eFellows engineer who has read the 3GPP specs — footnotes included.
One connected platform to run your GTP signalling and data path, manage it day-to-day, and prove it behaves to spec — before your customers find out otherwise.
Two products. One GTP assurance loop.
Secure and automate with GTP Proxy — test & assure with Blaze. Each stands alone, and each is stronger together.
GTP Proxy
A high-performance proxy in the GTP signalling and data path — inspecting, routing, filtering, and securing GTP‑C and GTP‑U traffic between network nodes, with Grace, its built-in operations console, for day‑to‑day configuration, monitoring, and policy control.

Emulate any GTP client or server, craft arbitrary messages and full procedures, and validate every Information Element against expected behaviour.

Real protocol substance, packaged for the whole team.
We actually speak GTP
Not just the mandatory fields — the optional Information Elements, the vendor Private Extensions, the cause-code edge cases most tools never touch. Depth is the product.
Confidence before you ship
Catch conformance regressions in staging, not in a live roaming interconnect.
CI-ready automation
Script procedures once, run them on every build — Blaze slots directly into your pipelines.
Built for regulated networks
Interoperability and conformance evidence your compliance and roaming partners can trust.
See your GTP network tested the way spec compliance demands.
Bring a procedure you're worried about. We'll show you how Blaze scripts and runs it, then validates that every node in it behaves exactly as specified — in minutes.
