FIPS is a US federal standard for computer systems and data security that mandates only compliant cryptographic algorithms and their implementations be used in a product’s cryptographic operations. A product is considered FIPS compliant if it uses verified crypto modules that have been certified by a laboratory approved by the National Institute of Standards and Technology (NIST). CloudVision has completed the FIPS certification process to allow users with both single-node and multi-node clusters to operate in FIPS mode. Intra-node communication is not yet certified and will follow in Phase 2.
