Kafka Encryption for Cardholder Data: Solving PCI Challenges with Kroxylicious

kroxylicious-kafka-integration

Encrypt Kafka messages at rest without changing app code — using Kroxylicious and OpenBao to meet PCI encryption requirements.

If you’ve ever dealt with PCI-DSS, you know it’s not just a checkbox, it comes with a bunch of encryption requirements, audit trails, and zero room for mistakes, especially when you’re handling full credit card data in transit. And if you’re streaming that sensitive information through Kafka? Well, you’ve got yourself a serious challenge.

I recently faced this exact situation: messages flowing through Kafka containing PAN, CVV, and expiration data. Naturally, the first question was how do we secure it end-to-end without refactoring our entire ecosystem or complicating life for developers?

That’s where Kroxylicious came in. It was a game-changer.
