What We Test
Uncovering Hidden Vulnerabilities
Enterprise Network Penetration Testing (ENPT) is a completely neutral market intelligence service. By tracking how international brands navigate A2P SMS and 2FA across global networks, we give operators the clarity they need to maintain SMS volumes and combat bypass fraud.
Unlike aggregator-led testing, where routing biases obscure the truth, GTC guarantees strict neutrality. We help you identify hidden revenue leaks in genuine enterprise traffic across traditional messaging and alternative channels such as WhatsApp, Telegram, Viber, or voice channels.
