TNS Targets Caller Identity Fraud as Latin America Tightens Voice Authentication Rules — Transaction Network Services, Inc.

Event summary

TNS to present at Telco Transformation 2026 (Aug 19-20) on protecting caller identity and phone numbers from spoofing.
Brazil's ANATEL enacted a rule in November 2025 requiring high-volume callers to validate call origin.
TNS claims fraudsters can damage a company’s reputation by spoofing its phone number, even without breaching systems.
The company promotes its Branded Calling and Authentication Suite alongside Spoof Protection as solutions.

The big picture

Latin America is emerging as a regulatory hotspot, with Brazil’s ANATEL rule setting a precedent for global compliance. TNS positions itself as a key enabler of secure branded communications, but must prove its solutions scale beyond high-compliance markets.
