AWS S3 Encryption
Objects stay in S3 for scale. Decryption still requires a key share you hold outside AWS.
The problem
Cloud-native keys still leave unwrap authority with the hyperscaler.
Buckets can be encrypted and still be readable by the account, the provider, or anyone who inherits IAM. For regulated data, the question is who can compel or inherit the unwrap.
SSE with AWS keys keeps AWS on the unwrap path.
A broad role can decrypt without anyone intending it.
Account structure often blurs who owns the key.
Audits ask who can unwrap, not whether SSE is on.

Key benefits
Protecting cloud data protection and ensuring regulatory compliance and business continuity with DuoKey's AWS S3 encryption
Encrypts sensitive data both at rest and in transit, ensuring unauthorised users cannot access sensitive information even if they breach cloud storage or intercept data transfers.
Maintains customer confidence and business operations by preventing costly data breaches, minimising downtime from security incidents and preserving brand reputation
Meets strict regulatory requirements like GDPR, HIPAA and PCI DSS by implementing encryption standards that protect customer data and reduce legal liability risks
In detail
Unlike traditional server-side encryption done with AWS KMS, which involves the AWS infrastructure having access to your encryption keys, DuoKey's client-side encryption ensures that the encryption process is performed locally on your client device. This keeps encryption keys under your control and reduces the risk of unauthorized access to sensitive data.
