Confidential computing has a gap: firmware you cannot verify.
Enterprise firmware for confidential VMs on AMD SEV-SNP and Intel TDX. Reproducible builds mean your security team and auditors can verify it.
Minimize what must be trusted. Verify what was built. Verify what is running.
Less firmware means less to attack, less to review and less to maintain. Sylica ships only what a confidential VM needs to boot.
Stop taking the vendor’s word. Your team or your auditor rebuilds the release from its published source and confirms it matches what runs in production.
Keys and secrets are released only to a VM whose firmware measurement matches the published value. Attestation becomes a policy decision, not a leap of faith.
Why not just upstream OVMF?
One architecture, three targets
The same reduced, reproducible firmware for conventional x86 VMs, so one firmware standard covers the whole fleet.
The firmware measurement is part of the SEV-SNP attestation report, so the VM’s start state can be checked before it receives a key.
The firmware runs inside the Trust Domain and is part of its measured start state, covered by the same check.
Where teams use it
Signed releases, SBOMs and documented measurements turn “we trust our provider” into evidence an auditor can check. Built for the CISO who owns the trust chain.
Cloud-provider firmware is a dependency you cannot inspect. Sylica gives the CIO one enterprise-controlled firmware standard across every cloud and on-premises, and strengthens digital sovereignty.
Finance, healthcare, government and defence run sensitive data on confidential VMs with a firmware foundation they can reproduce and defend to a regulator.
Models and training data are only as protected as the firmware beneath them. Verify it before the first key is released.
Release keys only to VMs whose firmware measurement matches the published value. Zero trust, down to the first code that runs.
Offer confidential VMs and multi-tenant confidential Kubernetes on firmware your customers can independently verify, backed by enterprise advisories and long-term supported releases.
Verify the firmware. Then trust the workload.
Security begins before the operating system starts. Talk to us about bringing Sylica to your SEV-SNP and TDX fleet: enterprise support, security lifecycle, attestation policy and a verification walkthrough with your security team.
