We don't just test GTP. We speak it fluently.
GTP Proxy and Blaze make up a GTP testing & assurance platform delivered by eFellows for mobile network operators, infrastructure vendors, and the QA teams that keep them honest. Our focus is narrow on purpose: GTP-C and GTP-U, understood down to the bit, done correctly, end to end.
Why we exist
GTP conformance failures are expensive to find in production — a dropped bearer, a rejected roaming session, an interconnect partner sending an Information Element your core doesn't expect. We built this platform so that class of failure gets caught in a pipeline, not a postmortem.
That's only possible because the eFellows engineers behind GTP Proxy and Blaze actually read the 3GPP TS 29.060 / 29.274 tables line by line — the mandatory IEs, the optional ones nobody implements the same way twice, the vendor Private Extension IEs, the cause-code edge cases. GTP Proxy — with Grace, its built-in operations console — and Blaze all encode that depth, not a superficial pass/fail wrapper around packet capture.
What we're not
We're not a general-purpose network testing tool with GTP bolted on. Every product in this platform — GTP Proxy and Blaze — is built around GTP-C and GTP-U procedures and Information Elements as first-class concepts, because that's the level of accuracy protocol-credible testing actually requires.
