All traffic exchanged between these Nitro instances is automatically encrypted with TLS, see encryption in transit. All AWS API service endpoints use TLS 1.2 (minimum), see AWS cloud connections with TLS. For RDS, you will need to download the certificate bundle for the RDS database you're using, add it as a Kubernetes Secret, and reference that secret in your Pod. See this post for additional details. I'm less familiar with Kafka and TLS, but it seems doable. According to the documentation, you'll need to add a certificate to your client's trust store, see https://docs.aws.amazon.com/msk/latest/developerguide/msk-authentication.html.

Encryption Support for AWS Transit Gateway - Amazon VPC
1 month ago - To support the end to end encryption of data between VPCs through the TGW, the transit gateway attached to the VPC should also have Encryption Support enabled. Transit gateway provides you with the option to enable encryption-in-transit capabilities by using AWS Nitro encryption capable instances.

September 1, 2025 - This isn’t a dry AWS manual, it’s the story of how I found a better way to keep data safe. Before I stumbled upon Nitro Enclaves, I was convinced my security practices were more than enough. I followed the list that every DevOps engineer knows i.e. lock down the network with VPC rules, assign least-privilege IAM policies, encrypt everything at rest in S3 or EBS, and…

For additional information and a list of supported instance types, refer to Encryption in transit. The encryption keys used for EBS, local instance storage, and for VPC networking are only ever present in plaintext in the protected volatile memory of the Nitro Cards; they are inaccessible to both AWS operators as well as any customer code running on the host system’s main processors.

1 month ago - You can configure specific exclusions for resources such as internet gateways or NAT gateways, that don’t support encryption (because the traffic flows outside of the AWS network). Other resources must be encryption-compliant and can’t be excluded. After activation, enforce mode provides that all future resources are only created on compatible Nitro instances, and unencrypted traffic is dropped when incorrect protocols or ports are detected.
