Encryption in payments: Evervault encryption vs. traditional encryption

The process of online payments begins with the client entering sensitive cardholder data, which must be protected through encryption to prevent unauthorized access and ensure compliance with standards like PCI DSS v4.0. Traditional encryption methods, using algorithms such as AES-256 and TLS 1.2+, face challenges in key management and maintaining compliance, often burdening engineering teams with complex processes and documentation. Evervault offers an alternative by providing encryption-as-a-service, simplifying the integration of payment security through a single SDK call or by routing traffic via Relay, a proxy that ensures data is encrypted immediately. Their solution involves performing cryptographic operations within AWS Nitro enclaves, ensuring that raw cardholder data never reaches application servers, thus enhancing security and easing compliance burdens. This approach allows teams to maintain control over payment pipelines while reducing the operational load associated with traditional encryption methods, enabling flexibility in payment processing and adherence to PCI DSS requirements.
