Project Overview

As per the latest Reserve Bank of India (RBI) guidelines, banks are required to migrate their public-facing domains from conventional domains such as .com to the secure .bank.in domain administered by IDRBT (Institute for Development and Research in Banking Technology). This initiative strengthens the security, authenticity, and trustworthiness of banking websites while reducing the risk of phishing and domain spoofing attacks.

Our team at Isarva successfully planned and executed the complete migration of Gokarnanath Bank's website and email domain from gokarnanathbank.com to gokarnanath.bank.in, ensuring a smooth transition with minimal disruption to banking operations.

Email Domain Migration
