ZeroTier partners with Redapt to deliver post-quantum networking.

ZeroTier partners with Redapt to deliver post-quantum networking. Mohib Ur Rehman Insider Brief * ZeroTier has partnered with Redapt to integrate its ZeroTier Quantum networking platform into Redapt's infrastructure, cloud and managed services offerings. * The platform uses post-quantum cryptographic standards, including ML-KEM-1024 (FIPS 203) and ML-DSA-87 (FIPS 204), to secure connectivity across data centers, cloud environments and distributed systems. * Redapt will assess, deploy and manage the platform for enterprise customers while also providing cybersecurity advisory services and virtual CISO support to ZeroTier. PRESS RELEASE - ZeroTier, one of the world's top software-defined networking companies, today announced a partnership with Redapt, an end-to-end technology solutions and systems integration provider specializing in data center infrastructure, cloud, AI, and managed services. Through the partnership, Redapt will integrate ZeroTier Quantum, the world's first end-to-end quantum secure networking platform, into its cloud, infrastructure, and services offerings to help enterprises secure private cloud, co-location, and dedicated environments against emerging quantum threats. Both companies have strong footprints in markets like government, defense, finance, and regulated gaming. "Quantum security can't remain a future roadmap item for enterprise-level infrastructure," said Andrew Gault, ZeroTier's CEO. "Organizations are already rethinking how they secure private environments, especially as infrastructure becomes more distributed. Redapt understands how to operationalize complex environments at scale, and together with ZeroTier, we're making it easier for customers to deploy quantum-secure networking as part of a complete managed solution." Redapt works with enterprises to design, deploy, and manage complex infrastructure environments across on-premises and cloud systems, with a focus on industries such as defense, financial services, and regulated gaming. By combining ZeroTier Quantum with Redapt's infrastructure and managed service capabilities, customers can now deploy private, quantum-secure connectivity across distributed systems without the complexity of traditional networking approaches. The partnership provides organizations with a practical path to quantum-resilient infrastructure while simplifying connectivity across data centers, cloud environments, edge deployments, and remote systems. Many organizations that Redapt serves hold data that must stay confidential for years - with many asking how to protect against "harvest now, decrypt later" threats without re-architecting the networks they run today. "Customers want infrastructure solutions that are secure, flexible, operationally simple, and now, quantum secure," said Rick Cantu, Redapt's CEO and Co-Founder. "ZeroTier Quantum gives us a way to add FIPS quantum-secure networking aligned with CNSA 2.0 standards directly into the environments we already build and manage for our customers. Most of our customers can't pause operations to rebuild their networks for a quantum future. ZeroTier Quantum lets us fold quantum-secure connectivity into the infrastructure we already design, deploy, and manage, so security teams can act on the threat now instead of waiting on a multi-year migration." ZeroTier Quantum is the first end-to-end quantum-secure networking platform on the market. Designed for on-wire, data center-level speed, ZeroTier's quantum cryptographic construction meets NIST and NSA's highest standards at CNSA 2.0. The platform implements NIST-standardized ML-KEM-1024 (FIPS 203) for key exchange and ML-DSA-87 (FIPS 204) for digital signatures. ZeroTier Quantum is built for resilient connectivity, flexibility, and the highest levels of cryptographic security. It introduces the ZeroTier Transport Protocol (ZTP), a packet-based protocol that embeds hybrid FIPS-compliant post-quantum cryptography directly into the transport layer. Further, ZeroTier Quantum supports perfect forward secrecy and, as a software platform, is adaptable to complex use cases. Redapt will offer ZeroTier Quantum as part of broader infrastructure engagements. Redapt will assess, design, deploy, and manage ZeroTier Quantum alongside the compute, storage, networking, and cloud environments it already delivers, so quantum-secure connectivity is configured, tested, and supported as part of the solution rather than added afterward. "This partnership opens a new commercial channel for ZeroTier Quantum, giving enterprises a direct path to deploy quantum-secure networking across their critical infrastructure," said Robert Stevenson, ZeroTier's CCO. "We're already seeing strong traction with ZeroTier Quantum in the enterprise market, and our partnership with Redapt builds on that momentum. By combining our technology with Redapt's infrastructure expertise and managed services, we can accelerate adoption and help customers strengthen security without disrupting existing operations." Expanding the Partnership Beyond the technology integration, this new partnership also reflects a broader strategic relationship between the two companies. Redapt will provide cybersecurity advisory and strategic security guidance to ZeroTier and act as the company's virtual CISO. This includes supporting ZeroTier's security strategy, risk management, and IT infrastructure. Redapt will also provide guidance and active management on security policies, technology assessments, and long-term infrastructure planning. Building on ZeroTier's existing compliance framework, the partnership will further strengthen compliance readiness and help prepare the company for additional certifications. This new partnership reflects growing enterprise demand for integrated infrastructure and security solutions that can adapt to rapidly evolving operational and threat environments. Together, ZeroTier and Redapt will help organizations build and manage secure, scalable infrastructure designed for long-term resilience. Mohib Ur Rehman.

ZeroTier wins Money20/20 pitch with quantum-secure platform.

ZeroTier wins Money20/20 pitch with quantum-secure platform. Tue, 3rd Nov 2026 (Today) ZeroTier won the startup pitch competition at Money20/20 USA in Las Vegas for ZeroTier Quantum, its quantum-secure networking platform. The result marks a push by ZeroTier into financial services, where banks and other institutions are weighing how to address post-quantum security risks across ageing technology estates. The issue is becoming more urgent because financial infrastructure upgrades often take years, while information encrypted today could become readable in the future if quantum computing advances far enough. In the industry, that is often described as a risk that data can be collected now and decrypted later. For lenders, payment groups and other financial firms, the exposure is tied to the long life of customer, transaction and account records. Many operate across a mix of legacy systems, private data centres and cloud environments, making security upgrades difficult to carry out quickly across all networks. ZeroTier Quantum is a software-defined network overlay designed to secure point-to-point connections across hybrid cloud, multi-cloud and site-to-site deployments. The approach is intended to help institutions protect data in transit across existing systems without replacing every part of the underlying infrastructure at once. That pitch appears to have resonated at a competition attended by a large startup and investor audience from the financial technology sector. According to Money20/20, the event brought together more than 900 startups alongside founders, funders and investors. "Winning the Money20/20 startup pitch competition is meaningful validation for ZeroTier as we bring our platform to the financial services market," said Robert Stevenson, Chief Commercial Officer at ZeroTier. Stevenson linked the award to a broader shift in how financial institutions are approaching quantum-related cyber risk. "Financial institutions are confronting a complex, long-term migration challenge as quantum risk becomes more immediate. ZeroTier Quantum gives them a practical way to begin protecting connectivity across existing infrastructure now, while building toward a broader crypto-agile strategy," Stevenson said. Sector pressure The financial sector has been paying closer attention to post-quantum cryptography as regulators, standards bodies and security teams assess how current encryption methods may need to change over time. The challenge extends beyond banks to insurers, payment processors, capital markets firms and any business holding sensitive data that must remain confidential for long periods. In practice, much of the difficulty lies in the scale of migration. Institutions may need to review internal systems, third-party connections and data moving between branches, clouds and processing centres while keeping core services running. That makes products designed to sit on top of existing infrastructure attractive to firms trying to limit disruption. ZeroTier is entering that discussion from a networking angle rather than through a full replacement of core systems. Its argument is that point-to-point traffic can be protected earlier in the migration cycle, giving firms a way to start addressing some risks before broader modernisation work is complete. ZeroTier also said ZeroTier Quantum meets NIST and NSA standards at CNSA 2.0, placing the product within a framework many large organisations watch when assessing security tools for long-term deployment. In financial services, buyers often look for alignment with recognised standards as they plan procurement and compliance decisions. Company profile ZeroTier is known for software-defined networking products that connect devices and systems through networks managed by customers. It serves organisations across multiple industries and is backed by Anorak Ventures, Battery Ventures and Bonfire Ventures. The Money20/20 award gives the company visibility as it seeks to build business in a market where cybersecurity spending remains resilient, particularly around data protection and infrastructure risk. For financial institutions, the question is less whether post-quantum change will be needed than how to begin the process without waiting for a full rebuild of legacy estates.
