Broadcom Urges Enterprises to Prepare Now for Post-Quantum Cyber Threats

Key Points

• Interested in Broadcom Inc.? Here are five stocks we like better.

• Broadcom urges enterprises to begin post-quantum planning now, including identifying cryptographic use cases, inventorying systems and mapping dependencies, even though the timing of quantum threats remains uncertain.

• Quantum computers could eventually break widely used RSA and elliptic-curve encryption, while "harvest now, decrypt later" attacks pose an immediate concern for sensitive data with long-term value.

• Companies should use a risk-based migration strategy, prioritizing critical systems, addressing weak or outdated cryptography and integrating post-quantum preparations into broader cyber-resilience plans.

Enterprises should treat post-quantum cryptography as a current business issue rather than a distant technology concern, according to Michael Jordan, Distinguished Engineer for Cybersecurity and Compliance at Broadcom (NASDAQ:AVGO).

Speaking during The Six Five Summit's AI Unleashed 2026 event, Jordan said post-quantum cryptography, or PQC, refers to cryptographic algorithms that run on classical computers but are designed to resist attacks from quantum computers. The issue is increasingly important because cryptography has become foundational to modern IT operations, including web applications, APIs, hybrid cloud environments, cryptocurrency and asset tokenization.
