Challenges

The client, a financial technology company specializing in payment processing solutions, developed a payment gateway application hosted on a cloud platform. To enhance security, streamline network management, and achieve regulatory compliance, they wanted to migrate the application to AWS. Their ideal solution included robust endpoint protection, a SIEM solution, secure integration with SaaS products and private data centers, and a centralized dashboard to capture vulnerabilities, identify them during the build process, and prevent deployment if critical issues are found.
