Offline Root CA

Cohesively secure the root CA to ensure full integrity of your public key infrastructure (PKI) ecosystem.

Offline Root CA Solutions

Futurex’s offline root CA ensures the highest level of trust within your Public Key Infrastructure (PKI) by securing root keys in an offline environment. This approach prevents unauthorized access and enhances security by isolating root keys from network vulnerabilities. With Futurex, you achieve robust protection and trust in your cryptographic hierarchy, ensuring a secure foundation for your entire PKI.

Use Cases

Hardware-backed Security

Futurex helps you enhance your security infrastructure with hardware-backed security, utilizing its advanced FIPS 140-2 Level 3-certified HSMs for securing offline root CAs. This turnkey solution offers a comprehensive, all-in-one box approach which ensures optimal protection for critical cryptographic assets and simplifies the deployment and management of cryptographic environments.

Key Lifecycle Management

Futurex’s secure and centralized platform helps you seamlessly manage the end-to-end lifecycle of your cryptographic keys, including key generation, distribution, rotation, and retirement, enhancing data protection and compliance. This helps organizations maintain robust security protocols and streamline their entire cryptographic operations.

Trust Chain Integrity

Secure the certificate trust chain's integrity by isolating the root of trust. Subordinate CA certificates, generated and validated out-of-band, allow the issuance of further certificates, establishing a secure, hierarchical trust structure. This ensures a robust, independently protected certificate ecosystem that is ideal for safeguarding digital communications and transactions.

Disaster Recovery (DR)

Facilitates robust DR by ensuring the root CA is securely restored in case of data compromises. By keeping the root CA offline, organizations significantly reduce their scope of compliance by separating the CA from potentially malicious third parties on the network.

Generate Keys Securely

The root CA (which is always kept offline) generates a self-signed certificate that serves as a trust anchor. It securely signs external Subordinate CA signing requests, with certificates validated out-of-band. This ensures a secure chain from Subordinate CAs to the root CA and preserves the integrity of the entire certificate infrastructure.

Reduced Scope of Compliance

Keeping the root CA offline isolates it from network threats, minimizing compliance requirements.


Enhanced Trust

The root CA acts as the trust anchor in PKI ensuring that all users trust the issued certificates.


icon_data security

Enhanced security and privacy

Maintaining the root CA offline protects the organization's most sensitive information, ensuring the privacy and integrity of communication channels secured by PKI.


Compliance scope reduction

By isolating the root CA offline, organizations reduce compliance scope, minimizing exposure to potential threats and vulnerabilities from the network environment. This separation safeguards against malicious third-party access.


Rapid incident response

In the event of compromise or security incidents involving online issuing CAs, an offline root CA enables swift response measures such as revoking compromised certificates, issuing new CRLs, and generating new SubCA certificates.


Secure certificate authority infrastructure

VirtuCrypt Elements Offline Root CA Storage offers a highly secure infrastructure for managing root certificates. The root private key is stored offline within a FIPS 140-2 Level 3 and PCI HSM validated Secure Cryptographic Device, ensuring robust protection against unauthorized access and tampering.

Compliance adherence

This solution aligns with PCI PIN and P2PE requirements, which mandate that CAs used to sign subordinate CAs be maintained offline within a dedicated network. Adhering to these standards ensures compliance with industry regulations and security best practices.

TLS certificate management

The offline root CA establishes a secured chain of trust with the Issuing CA to facilitate TLS certificate management by issuing digital certificates to certify the ownership of public keys, ensuring secure communication channels and authentication in TLS-enabled environments.
