Pioneers in next-generation authentication and mobile app security.

Who we are

company 4 pillars 800px

Entersekt challenges the widely-held assumption that security and convenient access stand in opposition to each other.

As a category leader, we serve financial institutions and other service providers with the kind of strong user authentication and app security that analyst firms like Gartner predict will dominate the market by the end of the decade.

We’re not late to this game. Entersekt pioneered phone-as-a-token, out-of-band push authentication. Our portfolio of 56 patents proves it. Our products are mature and scalable, with proven track records.

We help protect tens of millions of end-users across the globe, securing 150 million digital transactions every month in 45 countries.

Build Transakt into your mobile app. With our best-of-breed, regulatory-compliant niche functionality in hand, your development teams can focus on their core responsibility – product innovation.

Some of our Customers

Security, when implemented correctly, becomes an enabler, unlocking exciting new capabilities and revenue opportunities. Our customers have increased revenue significantly by expanding their online and mobile services and increasing daily interactions with more convenient and engaging experiences, especially on mobile.

Transakt provides them that freedom. Fraud has been effectively eliminated on Transakt-protected digital channels, even as false declines and abandoned online shopping carts have dropped.
