CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Fortanix Confidential Computing
Enterprise security teams protecting sensitive computation on untrusted infrastructure need Fortanix Confidential Computing because it encrypts data while it's actively processing, not just in transit or at rest. Intel SGX and AMD SEV support across major cloud providers means you're getting hardware-backed isolation that the OS and hypervisor can't breach, directly strengthening PR.DS and PR.PS controls. Skip this if your threat model doesn't include a compromised cloud provider or if you're managing workloads that can't be refactored for enclave execution; Fortanix demands architectural changes, not just a policy checkbox.
Teams protecting stateless services or ephemeral infrastructure in airgapped or hostile networks should choose Tang for its ability to bind decryption to network presence rather than individual credentials. The free, open-source model (670 GitHub stars) means you can deploy it without vendor lock-in and audit the binding mechanism yourself. Skip Tang if your threat model requires per-user key derivation or if your decryption clients can't maintain reliable network connectivity to a single Tang server; network presence is a weaker signal than possession for most cloud-native architectures.
