The U.S. National Institute of Standards and Technology (NIST) has set 2030 as the target for deprecating quantum-vulnerable encryption, with full removal by 2035. Yet according to recent industry data, fewer than 5% of enterprises have a transition plan in place—a gap that could leave organisations exposed as quantum computing advances.
Live News
The race to adopt post‑quantum cryptography is falling behind schedule, according to a report from Quartz. NIST’s roadmap calls for the deprecation of all encryption algorithms that are susceptible to quantum computer attacks by 2030, and their complete elimination from systems by 2035. However, current surveys indicate that less than 5% of enterprises have developed a concrete migration plan.
The slow pace of adoption stems from the complexity and cost of upgrading cryptographic systems across networks, hardware, and software. Many organisations remain in the early awareness stage, lacking the specialised expertise or dedicated budget to begin planning. NIST has been standardising a suite of new post‑quantum cryptographic algorithms in recent years, but actual implementation across enterprise IT environments has lagged far behind the standards‑setting process.
The timeline is driven by the growing threat of “harvest now, decrypt later” attacks, in which adversaries collect encrypted data today with the expectation of breaking it once quantum computers become viable. Without a proactive transition, sensitive data—including financial records, intellectual property, and government communications—could become exposed within the next decade. The urgency is compounded by the long lead time required to overhaul deeply embedded cryptographic infrastructure, which often takes five to ten years in large organisations.

Key Highlights
- NIST’s dual‑stage timeline: Deprecation by 2030 and removal by 2035, yet enterprise readiness remains extremely low (below 5% with a plan).
- Systemic complexity: Replacing cryptography necessitates updates to everything from network protocols and hardware security modules to cloud services and legacy systems—a multi‑year effort.
- Security risk exposure: The “harvest now, decrypt later” threat model means that any data encrypted with current algorithms could be decrypted in the future, putting long‑lived secrets at risk.
- Industry implications: The cybersecurity sector may see rising demand for post‑quantum migration services, audit tools, and hardware that supports new standards.
- Regulatory pressure: As deadlines approach, regulators in financial services, healthcare, and critical infrastructure could impose stricter compliance requirements to ensure timely migration.

Expert Insights
The gap between NIST’s schedule and actual enterprise readiness suggests a potential crisis of preparedness. Transitioning cryptography is not a simple software patch—it requires careful inventory of all cryptographic assets, risk assessment, and phased upgrades that can take years to complete. Companies that start later may face a scramble closer to 2030, competing for limited vendor capacity and skilled talent.
From an investment perspective, firms that demonstrate early progress in post‑quantum readiness could be viewed as more resilient, while laggards may face higher compliance costs and reputational risks. The timeline—though ambitious—still provides a window for those who begin planning now. However, the clock is ticking: with fewer than 5% of enterprises having a plan as of mid‑2026, the majority are effectively already behind schedule. Proactive budgeting and cross‑functional coordination between IT, security, and executive leadership will be essential to avoid a last‑minute, costly transformation.
