Good Afternoon,
Here at Futurex, we have a dedicated service offering for this exact scenario.
If you prefer not to click links here, simply Google AWS Marketplace and Futurex, scroll to the bottom and expand on "Futurex Key Management as a Service (KMaaS) for AWS Payment Cryptography"
Can also email [email protected] and will be routed to me and we can connect for additional discussion.
Best Regards, Jason
