As payment security becomes a strategic priority for banks, a South African entrepreneur is developing a technological solution that is already drawing international attention.

Schalk Nolte is a South African entrepreneur and co-founder and chief executive of Entersekt, a company that secures online and mobile financial transactions for banks and other financial services firms.

Founded in 2008, Entersekt works with banks, credit unions, card issuers and other financial institutions to reduce fraud, increase revenue, meet regulatory requirements and improve customer experience.

The company says it holds more than 120 technology patents covering innovations in digital security, payments and user experience. It has more than 210 clients across 70 countries, including over 850 card-issuing banks, 550,000 merchants and around 360 million users of its software.

Entersekt offers a single platform designed to meet the needs of financial institutions. Its core functions include protecting against scams, preventing account takeovers and securing access to digital banking services. The platform also supports more reliable online payments through solutions that comply with market standards and help reduce pressure on call centers.

Nolte graduated from Stellenbosch University with a bachelor’s degree in electronic engineering in 1999. From 2022 to 2024, he was a member of YPO, a global network of business leaders. He also served on the board of LaunchLab, Stellenbosch University’s incubator, from 2022 to 2023.
