ZeroTier

Software-defined networking for secure, private networks

Overview

ZeroTier provides software-defined networking (SDN) solutions that let people create secure, private networks over the internet without relying on traditional hardware like routers and switches. It works by running client software on devices to form a virtual network fabric, securely routing traffic between remote sites, data centers, and endpoints through a centralized network stack. This makes it easier to connect devices and systems anywhere, supporting use cases like remote work, IoT management, and secure communications, with a freemium model that scales from individuals to enterprises. Unlike many networking products that depend on physical hardware and complex setups, ZeroTier focuses on software-based networking that can be deployed quickly across diverse environments. Its goal is to help users connect devices securely and efficiently across multiple locations by providing flexible, scalable private networks and enterprise-grade options.

Simplify's Take

What believers are saying

  • ZeroTier Quantum targets defense, sovereign, and air-gapped deployments without infrastructure rebuilds.
  • May 20, 2026 ZeroTier One v1.16.2 raised bridged nodes to 512.
  • New Central v2 on April 15, 2026 added APIs and service accounts for automation.

What critics are saying

  • Tailscale, NetBird, and Headscale commoditize mesh networking, shrinking ZeroTier's freemium conversion funnel.
  • Enterprise buyers can delay Quantum until CNSA 2.0 deadlines, pushing revenue beyond 2026.
  • A single control-plane outage or protocol flaw would cripple distributed customers and kill trust.

What makes ZeroTier unique

  • ZeroTier Quantum launched March 23, 2026, combining Rust, ZTP, and CNSA 2.0 compliance.
  • New Central's June 15, 2026 release added custom flow rules and ReBAC.
  • Carahsoft's August 6, 2026 partnership opens SEWP V access to U.S. agencies.

ZeroTier partners with Carahsoft to bring post-quantum secure networking to US public sector

ZeroTier has partnered with Carahsoft Technology Corp to bring its software-defined networking solutions to US public sector agencies. The partnership makes ZeroTier Quantum, the company's quantum-secure networking platform, available through Carahsoft's distribution network and the NASA SEWP V contract. ZeroTier enables government agencies to deploy secure networks in minutes without traditional infrastructure. The platform connects users, devices, and workloads across cloud, on-premise, and edge environments. ZeroTier Quantum addresses emerging quantum computing threats by embedding post-quantum cryptographic resilience into the transport layer. The platform uses hybrid ML-KEM-1024 and ECDH P-384 cryptography and meets NIST and NSA CNSA 2.0 standards. It operates across public cloud, sovereign, and air-gapped environments whilst maintaining data sovereignty.

ZeroTier and Carahsoft partner to bring post-quantum secure, software-defined networking to the Public Sector.

ZeroTier and Carahsoft partner to bring post-quantum secure, software-defined networking to the Public Sector. * 2 hrs ago ZeroTier, one of the world's top software-defined networking companies, and Carahsoft Technology Corp., The Trusted Government IT Solutions Provider(R), today announced a strategic partnership. Under the agreement, Carahsoft will expand access to ZeroTier solutions across the Public Sector through its distribution network, making the company's software-defined, end-to-end quantum-secure networking platform, ZeroTier Quantum, available to the Public Sector through Carahsoft's reseller partners and the NASA Solutions for Enterprise-Wide Procurement (SEWP) V contract. ZeroTier provides Government agencies and defense organizations with a faster, more secure approach to connecting critical operations. Individuals, teams and organizations can securely link users, devices and workloads across cloud, on-premise and edge environments without complex hardware or completely new buildouts. Highly secure networks can be deployed in minutes, scaled on demand and operate in sensitive environments where resilience, control and security matter most. Beyond today's evolving threat landscape, quantum computing is rapidly advancing, enabling a new threat dynamic that will significantly challenge existing cryptographic security standards the world has relied on for more than two decades. England fans in Miami ahead of England's World Cup quarter-final against Norway "Public Sector agencies today are operating in a threat environment that's more distributed, more dynamic and more demanding than ever," said Andrew Gault, CEO of ZeroTier. "They require secure, resilient connectivity they can deploy quickly even in complex environments. For defense organizations, the stakes are even higher, requiring next-generation security and connectivity that can keep pace with the looming quantum threat and complex mission requirements. Through Carahsoft's strength and reach, agencies can more easily access ZeroTier's platforms through established procurement channels to rapidly accelerate their deployments." As the threat landscape continues to evolve, ZeroTier Quantum redefines secure networking by embedding post-quantum cryptographic resilience directly into the transport layer. Leveraging the ZeroTier Transport Protocol (ZTP) and a memory-safe Rust architecture, the platform implements hybrid ML-KEM-1024 and ECDH P-384 cryptography to neutralize 'harvest now, decrypt later' and 'trust now, forge later' threats. By meeting rigorous NIST and NSA CNSA 2.0 standards, ZeroTier Quantum delivers high-performance, infrastructure-agnostic connectivity that functions seamlessly across public cloud, sovereign and air-gapped environments, helping Government agencies maintain data sovereignty and operational continuity without sacrificing agility. "The White House and international security agencies are clear: the threat of quantum computing cracking modern encryption isn't a future problem; It's a today problem. We designed ZeroTier Quantum to not only enable the next generation of high-performance, resilient capabilities, but to provide a robust quantum defense capability," said Robert Stevenson, Chief Commercial Officer at ZeroTier. "ZeroTier Quantum gives agencies and defense organizations a practical path to end-to-end quantum-secure networking right now, with the flexibility to support mission-critical operations across cloud, edge, tactical, air-gapped and even offline environments." Built on a Zero Trust architecture, ZeroTier Quantum provides agencies with a practical path to adopting NIST-approved post-quantum cryptography well ahead of Federal compliance deadlines. For next-generation platforms, including drones, sensors and software-defined vehicles (SDVs) reliant on Communication Security (COMSEC), it embeds post-quantum resilience out of the box. In software applications, ZeroTier Quantum integrates directly to enable rapid adoption of post-quantum cryptography while enhancing security and operational agility. For legacy infrastructure and High Value Assets (HVAs), it can encapsulate underlying platforms with a secure overlay, enabling immediate modernization without the cost, complexity or disruption of replacing underlying infrastructure. "Government agencies are evaluating technologies that strengthen cyber resilience while preparing for the transition to post-quantum security," said Mark Demerse, Sales Director who oversees the ZeroTier Team at Carahsoft. "ZeroTier Quantum delivers a flexible, software-defined approach that enables organizations to modernize secure connectivity without disrupting existing infrastructure. Together with our reseller partners, Carahsoft and ZeroTier are helping Government agencies accelerate network modernization, enhance cyber resilience and simplify the transition to post-quantum security with faster deployment and reduced complexity." From secure remote access and tactical edge deployments to high-availability site-to-site connections and critical infrastructure protection, ZeroTier supports some of the most demanding Public Sector environments. ZeroTier's solutions are available through Carahsoft's SEWP V contracts NNG15SC03B and NNG15SC27B. For more information, contact the Carahsoft Team at (888) 964-7379 or [email protected].
