FLIK Security

Security is a shared responsibility.

Introduction

FLIK is an Indonesian fintech platform enabling seamless payments and financial services for businesses and consumers. We believe that security is fundamental to earning and maintaining the trust of our users, partners, and the broader ecosystem.

We invite security researchers, ethical hackers, and the broader security community to help us identify and address vulnerabilities in our systems. This responsible disclosure policy outlines how we work together to keep FLIK and our users safe.
