Amazon ElastiCache for Redis now PCI DSS compliant, allowing you to process sensitive payment card data in-memory for faster performance

Amazon ElastiCache for Redis has achieved the Payment Card Industry Data Security Standard (PCI DSS). This means that you can now use ElastiCache for Redis for low-latency and high-throughput in-memory processing of sensitive payment card data, such as Customer Cardholder Data (CHD). ElastiCache for Redis is a Redis-compatible, fully-managed, in-memory data store and caching service in the cloud. It delivers sub-millisecond response times with millions of requests per second.

To create a PCI-Compliant ElastiCache for Redis cluster, you must use the latest Redis engine version 4.0.10 or higher and current generation node types. The service offers various data security controls to store, process, and transmit sensitive financial data. These controls include in-transit encryption (TLS), at-rest encryption, and Redis AUTH. There’s no additional charge for PCI DSS compliant ElastiCache for Redis.

In addition to PCI, ElastiCache for Redis is a HIPAA eligible service. If you want to use your existing Redis clusters that process healthcare information to also process financial information while meeting PCI requirements, you must upgrade your Redis clusters from 3.2.6 to 4.0.10. For more details, see Upgrading Engine Versions and ElastiCache for Redis Compliance.

Meeting these high bars for security and compliance means ElastiCache for Redis can be used for secure database and application caching, session management, queues, chat/messaging, and streaming analytics in industries as diverse as financial services, gaming, retail, e-commerce, and healthcare. For example, you can use ElastiCache for Redis to build an internet-scale, ride-hailing application and add digital wallets that store customer payment card numbers, thus enabling people to perform financial transactions securely and at industry standards.
