Arqit SKA-Platform vs CipherStash Stash: Side-by-Side Comparison (2026)

Arqit SKA-Platform: Quantum-safe key agreement platform for securing comms across endpoints. built by Arqit. Core capabilities include Dynamic quantum-safe encryption key generation at endpoints via lightweight software agents, Over-the-Air (OTA) bootstrap key delivery using NIST ML-KEM post-quantum algorithms, Mutual authentication with per-session key rotation for perfect forward secrecy..

CipherStash Stash: TypeScript secrets manager with zero-trust vault and cryptographic audit trails. built by CipherStash. Core capabilities include Encrypted secrets vault with local decryption (plaintext never leaves the process), Immutable, cryptographically proven audit trail for every secret access event, TypeScript SDK (@cipherstash/protect) and CLI for managing secrets..

Both serve the Quantum Security market but differ in approach, feature depth, and target audience.
