Automated Software Supply Chain Security & Code Signing Enclaves

Securing software build systems, firmware images, and container registries against supply chain tampering through hardware-isolated code signing.

Protecting the DevOps Pipeline from Key Theft

Software supply chain breaches often stem from stolen private code signing keys stored in insecure CI/CD environment variables. SignHSM eliminates this risk by keeping code signing keys permanently inside FIPS 140-3 Level 4 hardware, requiring cryptographic mTLS attestation from build runners.

Line-Rate Container & Firmware Signing

With hardware signing throughput exceeding 120,000 operations per second, SignHSM signs container layers, eBPF binaries, and microcode updates without introducing bottlenecks into continuous delivery pipelines.

Pipeline Integration: Native integrations with Sigstore, Cosign, Microsoft SignTool, and Linux kernel module signers.
Ephemeral Build Tokens: Issuing short-lived, role-based code signing credentials tied to verified CI/CD build runners.
Multi-Party Quorum: Requiring multi-engineer cryptographic sign-off for production firmware and operating system releases.
Tamper-Proof Audit Logs: Cryptographic logging of every compiled binary hash, git commit SHA, and release engineer identity.
