As enterprises face growing pressure to modernize networks while protecting sensitive data for years to come, AT&T Business today announced it is the first major North American service providers to launch a Quantum Resilient SD-WAN service that delivers post-quantum cryptography powered by the Cisco 8000 Series Secure Router. This new offering is designed to deliver secure and resilient connectivity that equips organizations with next-generation cryptographic defenses designed to help protect critical data against the rapidly evolving threats posed by quantum computing.
Securing the Future Against Quantum Threats
As quantum computing advances, the traditional encryption models that underpin today’s networks are fundamentally challenged. While large scale quantum systems are still emerging, the security risk is building. Data captured today can remain vulnerable for years into the future, making timing a critical decision for business leaders responsible for risk, compliance, and trust.
For organizations that handle sensitive or regulated information, delays reduce choice. Once encrypted data is intercepted, it cannot be protected later. Early action preserves control over how and when security environments evolve, avoiding rushed transitions and operational disruption down the road.
At the same time, governments are advancing post-quantum security requirements. Compliance expectations are becoming clearer, particularly for industries such as finance, healthcare, and the public sector. Early adoption strengthens readiness, reinforces trust with customers and partners, and positions enterprises ahead of regulatory mandates rather than in reaction to them. By integrating a PQC solution which aligns to NIST standards into AT&T’s SD-WAN portfolio, AT&T Business is helping organizations take practical, forward-looking steps in the transition to quantum-resistant networks, maintaining compliance and safeguarding national security interests.
A Collaboration Built on Resilient Connectivity
The launch of PQC secure SD‑WAN reflects AT&T Business’ longstanding collaboration with Cisco to modernize enterprise networking and security. Together, the companies combine AT&T’s global network scale and experience supporting mission-critical enterprises with Cisco's leadership in secure routing and cryptographic innovation.
This builds on AT&T Business’ recent expansion of integrated Security Service Edge (SSE) capabilities within its SD‑WAN portfolio, reinforcing a broader strategy to deliver converged networking and security services that evolve with emerging threats. The result is a converged networking and security architecture that helps businesses address immediate risks while preparing for what comes next.
As enterprises make long term decisions about how their networks will support increasingly sensitive data, quantum related risk can no longer be treated as a distant concern," said Joe Petrocelli, Vice President of Communication Services, AT&T Business. "By integrating Post Quantum Cryptography into our SD‑WAN offerings, we’re helping customers reduce their risk exposure and protect critical information for the future. Our continued collaboration with Cisco allows us to deliver business grade connectivity that evolves alongside the security needs of highly regulated industries."
Quantum computing represents a threat to today's ways of securing the network, users, and data, and our collaboration with AT&T Business is about proactive defense,” said Lee Peterson, Vice President of Secure WAN Product Management at Cisco. “By delivering a quantum resilient SD-WAN fabric, we are giving enterprises the tools to protect their data today against the threats of tomorrow. This milestone represents our commitment to delivering a quantum-ready, SASE-enabled architecture that provides our customers with the peace of mind to innovate in an increasingly complex threat landscape."
Global Availability Begins Later This Year
The new PQC secure SD-WAN service, powered by the Cisco 8000 Series Secure Router, will be available later this year to AT&T Business customers globally. The Cisco 8000 Series Secure Routers are purpose-built to deliver comprehensive quantum-resilient solutions including encryption, authentication, and secure boot capabilities with standards-based implementation to meet industry compliance. The service will be part of AT&T’s broader SD‑WAN offerings, supporting enterprises as they modernize networks and plan for future security requirements.
