How Visa built its own container security solution

Like many large enterprises, financial services giant Visa has embraced containerization technologies that enable companies to move from legacy monolithic apps to microservice-based application architectures that are easier to maintain, update and deploy at scale on cloud infrastructure. But splitting apps into microservices also comes with the challenge of ensuring the containers hosting the various parts are properly monitored and protected from attacks.

Instead of deploying a combination of commercial solutions and spending resources on getting them to work for its environment, Visa’s security team went back to basics and created its own continuous monitoring solution that handles security policy enforcement, incident detection and remediation, a project that earned the company a CSO50 Award for security excellence.
