Phylax ZeroTrust
Distributed identity and access management for federal agency environments. No single administrator holds a complete signing key. No single compromise brings down the authorization layer. Delivered through Encore's federal integration practice, with technology developed by Phylaxone.
Built to Remove the Single Point of Failure
Federal identity systems built on traditional public key infrastructure share a structural problem: one authorized administrator, one compromised HSM, or one insider event can invalidate the entire signing authority. Agencies have spent years hardening the perimeter around that central point without removing it.
Phylax ZeroTrust removes the central point. The FROST protocol distributes signing authority across a defined set of independent key holders. A threshold of those holders must cooperate to produce a valid signature. No single party can act unilaterally.
Phylax ZeroTrust is developed and maintained by Phylaxone. Encore holds a federal deployment license and delivers the full integration, ATO support, and managed service layer for government agency environments.
The Federal Zero Trust Mandate
Federal zero trust strategy requiring continuous identity verification and elimination of implicit network-based trust. Agencies were required to reach specific zero trust milestones by end of fiscal year 2024.
Zero trust architecture standard. Phylax ZeroTrust applies resource-level policy enforcement and continuous verification consistent with this publication.
Executive orders on improving national cybersecurity. Threshold signing and distributed key management address the supply chain and insider threat concerns raised in both orders.
Four Integrated Capabilities That Remove Central Trust
Phylax ZeroTrust uses the FROST protocol to distribute cryptographic signing authority across multiple independent parties. No single node, administrator, or system holds a complete signing key. A defined threshold of authorized parties must cooperate to produce a valid signature.
- FROST threshold Schnorr signatures across distributed key holders.
- Configurable quorum requirements by access tier and sensitivity level.
- Signing events logged with full participant attestation.
- Compatible with existing HSM infrastructure and FIPS 140-3 boundary requirements.
Access decisions are made continuously, not at the perimeter. Every transaction is verified against current identity state consistent with NIST SP 800-207 and the federal zero trust strategy under OMB M-22-09.
- Continuous verification against agency identity providers via SAML and OIDC.
- Policy enforcement at the resource level, not the network perimeter.
- Attribute-based access control with role separation for privileged operations.
- Session isolation and re-authentication triggers on context change.
Key material is never assembled in one place. Threshold operations require coordinated participation from designated key holders. No single system or administrator can authorize a signing event unilaterally.
- Multi-party computation for key generation and signing operations.
- Audit-grade participation logs for every threshold operation.
- Designed for environments where insider threat and external compromise are both active concerns.
- No single point of key compromise.
Phylax ZeroTrust is delivered through Encore's federal integration practice. Encore handles agency environment assessment, deployment planning, integration with existing identity infrastructure, and ongoing operational support.
- Deployment in AWS GovCloud, Azure Government, and on-premises environments.
- Integration with existing PIV, CAC, and agency identity provider infrastructure.
- ATO support documentation and system security planning assistance.
- Ongoing managed support through Encore's federal services team.
Past Performance Across Key Federal Agencies
Veteran identity systems, benefits access platforms, and healthcare data environments face persistent authentication and authorization risks. Distributed signing removes the key exposure that makes centralized VA identity infrastructure a high-value target.
DHS mission environments require verifiable identity across distributed operational teams. Threshold-signed authorization cannot be forged by a single compromised node or administrator account.
Geospatial data handling requires access controls that hold up under audit and congressional review. Threshold signing provides a defensible, logged authorization record for every access event.
Screening systems and operational access require identity controls that cannot be bypassed by a single compromised credential. Phylax ZeroTrust enforces quorum-based authorization at the access layer.
GSA procurement systems handle contract data that requires demonstrable access controls. Distributed signing provides an auditable authorization trail aligned to federal acquisition integrity standards.
