ZeroTier, an industry leader in software-defined networking, announced the launch of Release Candidate 2 (RC2) for ZeroTier Quantum, the world’s only end-to-end quantum-secure networking platform. The major milestone brings the software-only network overlay to the edge of General Availability (GA). It delivers a highly efficient, defense-grade encryption fabric designed to neutralize emerging cryptographic risks across distributed enterprise landscapes.
The introduction of RC2 arrives amid tightening global post-quantum cryptography (PQC) compliance deadlines. Strategic security frameworks, including the U.S. National Security Agency’s Commercial National Security Algorithm (CNSA) 2.0 mandate, are moving rapidly toward requiring quantum-resistant networking for infrastructure acquisitions.
ZeroTier Quantum addresses these strict operational needs by allowing defense agencies, critical infrastructure providers, and cloud enterprises to embed post-quantum resilience directly into existing network routing layers without forcing expensive, disruptive hardware overhauls.
“Reaching our final release candidate milestone brings us to the precipice of a new era in network security,” said Andrew Gault, CEO of ZeroTier. “ZeroTier Quantum isn’t an incremental update; it’s a fundamental paradigm shift. We have engineered a platform that eliminates the false choice between absolute security and high network performance, allowing modern distributed enterprises to defend their data pipelines from quantum vectors today.”

Mitigating ‘Harvest Now, Decrypt Later’ Threats Natively
A primary driver behind the platform’s development is the escalation of “harvest now, decrypt later” tactics by sophisticated adversaries. In these scenarios, bad actors intercept and store encrypted high-value enterprise traffic today with the explicit intent of processing it through cryptanalytically relevant quantum computers (CRQCs) once the hardware matures.
ZeroTier Quantum neutralizes this vulnerability by replacing aging VPN and TLS structures with a memory-safe protocol architecture built from the ground up in Rust. The platform utilizes the ZeroTier Protocol (ZTP) to distribute a highly optimized, hybrid cryptographic stack:
Hybrid Cryptographic Pairing: Blends NIST-standardized ML-KEM-1024 quantum-resistant encryption algorithms with classical, pressure-tested AES-384 public-key infrastructure to create an immediate transitional safety net.
Decentralized Control Plane: Fully isolates the network configuration layer from active data streams. Node configurations are cryptographically signed by an orchestrator that can operate in an entirely air-gapped environment.
Peer-to-Peer Mesh Architecture: Establishes direct, authenticated node-to-node pathways to automatically traverse complex NAT boundaries, eliminating centralized routing bottlenecks.
Comprehensive Standard Compliance: Enforces robust defense-in-depth protection across distributed edge locations to comply cleanly with upcoming FIPS and CNSA 2.0 parameters.
Achieving High-Throughput Performance on Limited Compute
Historically, retrofitting legacy networking protocols with advanced post-quantum encryption caused significant operational drag, spiking processor usage and introducing severe network latency. ZeroTier Quantum overcomes this computational hurdle through advanced hardware cryptographic acceleration and highly parallelized data transport layers.
The software overlay achieves a 30% reduction in baseline CPU utilization compared to traditional software-defined networking setups. Combined with a lightweight memory control plane and adaptive packet buffering, the platform maintains near-wire throughput speeds of up to 10 Gbps.
This footprint allows organizations to scale quantum defenses effortlessly across memory-constrained Internet of Things (IoT) hardware, remote drone fleets, and edge manufacturing nodes that cannot run heavy legacy agents.
“Our strategy has been clear and the marketplace traction we’re seeing with ZeroTier Quantum in its core configuration ahead of GA has been brisk,” said Robert Stevenson, CCO at ZeroTier. “Our securing commercial and proof-of-concept relationships across defense, enterprise cloud, and critical infrastructure proves that quantum-resilience is no longer a theoretical concern. It’s an operational requirement.”
Following the RC2 deployment, ZeroTier’s technical roadmap includes completing a rigorous, independent third-party code validation and external penetration test to prepare the software for its formal commercial GA launch later this year.
The enterprise evaluation program is active, and ZeroTier is inviting select corporate infrastructure partners to participate in final validation testing. Systems engineers, network operations directors, and chief information security officers can access API guides, explore topological layout models, and request a technical system demonstration by visiting ZeroTier’s official quantum intelligence portal.
