- AT&T and Palo Alto Networks launched a quantum-resilient SASE platform for enterprises
- The offering combines post-quantum cryptography with Prisma SASE security
- AT&T extends quantum-safe protection across 5G, fiber and hybrid networks
AT&T Business and Palo Alto Networks have unveiled a new Quantum-Resilient SASE Fabric designed to help enterprises prepare for future cybersecurity threats posed by quantum computing. The companies said the offering combines secure networking, cloud-delivered security and post-quantum cryptography (PQC) to protect business data as advances in quantum computing begin to challenge traditional encryption methods.
According to the companies, quantum computing could eventually undermine widely used cryptographic algorithms such as RSA and Diffie-Hellman, creating risks for organizations that rely on long-term data protection. In response, Palo Alto Networks is embedding PQC capabilities into its Prisma SASE platform, using standards-based hybrid encryption approaches that combine classical and quantum-resistant protections.
The new architecture includes TLS 1.3 encryption for control plane traffic, PQC-hardened data protection based on Internet Engineering Task Force standards and built-in crypto-agility that allows security algorithms to be updated through software rather than hardware replacements. The platform also incorporates Secure Boot and TPM 2.0 technology to strengthen device authentication and system integrity.
AT&T said the partnership extends its Dynamic Defense strategy by applying quantum-ready protections consistently across multiple network transport options, including fiber, 5G and other connectivity services. Automated policy orchestration is designed to simplify deployment while helping customers address emerging compliance requirements in regulated industries.
The companies also highlighted integration between Palo Alto Networks’ security platforms and AT&T’s network backbone through Service Provider Interconnect (SPI), which they said enables quantum-safe connectivity without sacrificing performance. The approach is intended to secure distributed enterprise environments, including branch offices and cellular-connected edge locations.
AT&T and Palo Alto Networks positioned the launch as a practical step toward long-term quantum readiness, arguing that organizations should begin preparing now for the next generation of cybersecurity threats.
