The company’s one-of-a-kind approach harnesses the power of digital certificate technology with the convenience of mobile phones to provide financial services companies and their customers with full protection from online fraud.

Built on open technologies for high availability, scalability, and simple integration, Entersekt’s patented security products protect millions of devices and transactions daily, while complying with the world’s most stringent regulatory guidelines.

In 2011, Entersekt provided Nedbank in South Africa with a world-first push authentication solution and a world-first end-to-end mutual PKI solution on mobile. These allowed the bank to provide services via mobile which no other bank was able to do at the time. Our relationship with Nedbank is ongoing and strong.

    Lorien Gamaroff, CEO Bankymoon
