ORCA is a turnkey Offline Root CA Appliance that secures the foundation of your PKI. With tamper-proof hardware, protected key ceremonies, and simplified lifecycle management, it delivers the highest levels of trust, compliance, and sovereignty for your digital infrastructure.

Why ORCA?

Establishing an Offline Root CA is the foundation of a secure PKI, but traditional deployments are complex, costly, and error prone. Many GCC enterprises and government agencies struggle with: 

Specialized expertise requirements

Offline Root CA setup often needs niche PKI skills.

Integration
complexity

HSMs, OS hardening, backups, and compliance all must work together.

Regulatory pressure

Europe and GCC data laws require trusted root authorities and strong governance.

Security risks

Without proper isolation and governance, a compromised Root CA can undermine the entire trust chain.
