Use Cases

Cloud Infrastructure

Hardware-attested confidential VMs and TEE-backed key management for hyperscale and sovereign cloud security teams.

Trust boundary Silicon
The Problem

Software key management has an irresolvable trust boundary

Keys that exist in RAM are vulnerable to hypervisor escape, cold-boot attacks, and privileged-admin access. Software HSM emulation cannot satisfy FIPS 140-3 Level 3 physical security requirements. The hypervisor is always in a position to observe keys — that is the nature of virtualization.

Cloud tenants running sensitive workloads — healthcare, financial data, government — cannot accept a trust model that requires trusting the hypervisor operator. Hardware-rooted isolation is the only architectural answer.

▲ Hypervisor escape (keys in RAM)
▲ Cold-boot key extraction
▲ Privileged admin API abuse
▲ Supply-chain firmware compromise
✓ Bastionchip: hardware-isolated
Bastionchip Solution

Hardware-attested cloud key management

Confidential VM attestation
Workloads in hardware TEE. Attestation token proves integrity to tenants without trusting the hypervisor or cloud operator.
BYOK with hardware custody
Customer-managed keys held in PCIe-attached HSM silicon on each host. No network latency, no centralized key service single point of failure.
HSM-backed secrets manager
Wrap and unwrap operations for secrets vaults (HashiCorp Vault, AWS KMS equivalent) rooted in Bastionchip HSM silicon on each node.
Sovereign key residency
Keys physically bound to a geographic node — key material cannot leave the silicon. Supports EU data sovereignty and government cloud requirements.

"Having attestation anchored in silicon rather than in a TPM driver stack eliminates an entire class of host-side attack scenarios we'd been modeling for years."
