His team of product managers, engineers and researchers deliver best-in-class enterprise security products and services to help to protect users, applications and infrastructure from cybersecurity threats. An innovation-driven technology leader who holds over 100 U.S. patents, Anand leads the AI transformation of the Network Security business. His team has developed a range of advanced security capabilities including: Prisma AIRS, a comprehensive AI security platform; Strata, an AI-powered platform; Cloud Delivered Security Services (CDSS); Secure Access Service Edge (SASE); Next Generation Firewalls (NGFW); and Zero Trust solutions. As a dynamic leader, Anand is dedicated to building strong, diverse and motivated teams focused on creating innovative security products and solutions for some of the world's biggest enterprise customers. Before joining Palo Alto Networks, Anand was SVP of Engineering for Cisco's Intent-Based Networking Group. At Cisco he was responsible for building the complete set of platforms and solutions for the Cisco enterprise networking portfolio. The portfolio spans enterprise products across routing, access switching, IoT connectivity, wireless, and network and cloud services deployed for customers worldwide. He joined Cisco through the acquisition of Starent Networks, and earlier in his career, held leadership roles at Siara Systems, Sun Microsystems and Ericsson. Anand holds a bachelor's degree in telecommunications from the College of Engineering, Pune, India and a master's degree in computer networking from the University of Southern California....

While the long-term, theoretical threat is clear, their immediate, top-of-mind concern should be the practical, multiyear journey of upgrading potentially thousands of devices, applications and data stores to be quantum-resistant. Make no mistake about it: This migration is complex, costly and touches every part of the enterprise. Further exacerbating this challenge is the "harvest now, decrypt later" threat. Nation-state actors are siphoning and stockpiling encrypted data today, waiting for the arrival of quantum computers to retroactively break it. This transforms a future computing problem into an immediate crisis for any data with long-term value. The U.S. government, through NIST and CISA, agrees the threat is real and has issued several new mandates starting this year.^[1](#footer-notes)^ As such, the industry is aligned on the danger and understands that, because the migration takes years, the time to start is now. For C-Suite leaders, this is your clear, actionable path forward. ## A Business Risk Disguised as a Technical Problem Leading customers I speak with have already pivoted past framing quantum computing as a distant, technical challenge. They rightly see it as a fundamental business risk to their continuity, their market position and their customers' trust. The most vulnerable data is the information with the longest shelf life: pharmaceutical formulas, growth strategies, aerospace designs and sensitive government intelligence. This makes the [quantum challenge](https://www.paloaltonetworks.com/perspectives/securing-the-economy-for-the-quantum-era/) fundamentally different from past IT threats. Unlike Y2K, which had a known fixed deadline, the quantum threat is retroactive. The damage from data stolen today will be realized years from now, making inaction a catastrophic failure of risk management. ## The C-Suite's Quantum-Readiness Framework A challenge of this magnitude requires a powerful and achievable strategic framework. The journey begins with a candid and comprehensive assessment of your cryptographic landscape. You cannot protect what you cannot see, making the essential first step to gain foundational visibility into your entire enterprise. This crypto inventory must be comprehensive, answering several questions: Which applications are using legacy encryption? Which devices, from servers to IoT, need to be upgraded? Which data stores are most at risk? Which third-party software and libraries are in your supply chain? Think of this as an MRI for your organization's cryptographic health. Visibility without action, unfortunately, is just a well-documented vulnerability. How do we fix it? Unfortunately, a "rip-and-replace" strategy is a fool's errand for any complex enterprise. A successful migration requires two distinct capabilities. The first one is crypto agility, which is the ability to swap or update cryptographic algorithms as new standards emerge or if one is found to be breakable. This is critical for future-proofing your architecture. But what about the legacy systems you can't easily replace? The second, and perhaps more immediate, capability is leveraging network-level controls --- sometimes called "cipher translation." They can instantly upgrade devices and applications so they appear quantum-ready to the rest of the network, all without reengineering them. This network-based approach enables you to address vulnerabilities in legacy systems without costly disruption, creating a secure foundation for what comes next. ## Leadership in the Quantum Era This transition will create a new dividing line between organizations that lead and those that lag. Yet, we won't know who is prepared until quantum computing arrives. It will be a defining moment for security and technology executives, one that will form the basis of digital trust for decades. A successful quantum-safe strategy is built on a unified security platform, not on a collection of point solutions. It prioritizes crypto agility over disruptive replacement and it begins with deep, enterprise-wide visibility. Beyond being a technical upgrade, it's a strategic evolution of your security posture. The quantum era hasn't arrived with a bang but with the quiet, retroactive decryption of today's secrets. The question, therefore, is no longer *if* your organization will be ready, but *how* you are leading the journey to get there.
