FIPS 140-3 is the current U.S. government standard for cryptographic modules. It defines strict rules for encryption algorithms, key management, authentication, and secure operation. If your workloads handle regulated information — financial transactions, healthcare records, government data — you cannot pass an audit without meeting these requirements.
In a microservices architecture, compliance is harder. Services talk to each other at high velocity, often across different physical and cloud environments. Each request carries the risk of becoming an attack vector. Without a centralized access proxy that enforces FIPS-approved cryptography, every microservice must implement its own controls. That creates gaps. Gaps get exploited.
A FIPS 140-3 Microservices Access Proxy solves this. It sits between services. Every inbound and outbound call passes through it. The proxy encrypts traffic with validated algorithms such as AES and SHA-2. It uses keys generated and stored in a FIPS-compliant module. It blocks non-compliant cipher suites. It logs every request with immutable timestamps and signatures. It handles TLS handshakes and mutual authentication so the services themselves stay lean.
