Enterprise Authentication Report

Global Intelligence for a Multichannel World

As enterprises shift to multichannel authentication, market transparency is disappearing.

GTC’s Enterprise Authentication Report cuts through the noise, providing the data-driven clarity needed to understand a complex ecosystem of SMS, WhatsApp, Flash Calls, and emerging bypass routes.

Why You Need Authentication Intelligence

The Structural Blind Spot

Enterprises today choose from a fragmented mix of channels (SMS, RCS, OTT, voice, etc.) to verify identities. Yet, MNOs and service providers struggle to track which channels their competitors are actually using in specific markets.

Regional Adoption

Deep-dives into country-level channel preferences.

GTC Multi-Channel TEST FLOW SCHEMA

Process overview & execution steps

Phase 1: Enterprise Initiation

Authentications are initiated through active in-house testing representing typical enterprise environments (e.g., PayPal login or verification requests).

Phase 2: Transit Hub Entry

GTC intercepts and tracks original credentials, tracking packet routing attributes on the Service Provider/A2P Ingress layer.

Phase 3: Routing & Channel Selection

Signal branches into official operator pathways or gets bypassed through secondary dark routes (such as SIM Farms, OTT apps, or illegal SS7 tunnels).

Phase 4: Node Reception

Our cloud and physical test nodes placed across 160+ countries and 500+ networks capture incoming signals instantaneously.

Phase 5: Automated Integrity Verdict

The Report Engine compares transit codes to received tokens, extracting headers & content metrics to output detailed bypass route verdicts.

Global Reach & High-Density Testing

Our intelligence is powered by an extensive global testing footprint:

160+ Countries

Testing capabilities across all major global regions.

500+ Mobile Networks
