Nearly two-thirds of organizations consider quantum computing as the most critical cybersecurity threat in 3–5 years

Core Insights - The Capgemini Research Institute report indicates that nearly two-thirds of organizations view quantum computing as a significant cybersecurity threat within the next 3-5 years [1][2] - A majority of early adopters of quantum-safe technologies anticipate that 'Q-day', when quantum computers can break current cryptographic algorithms, will occur within the next 5-10 years [1][2] Industry Concerns - Approximately 65% of organizations express concern regarding 'harvest-now, decrypt-later' attacks, which pose a risk to current encryption methods [2][11] - High-risk sectors such as defense and banking are leading the way in adopting quantum-safe solutions, while consumer-focused industries are lagging behind [3] Adoption of Post-Quantum Cryptography - 70% of organizations are implementing post-quantum cryptographic (PQC) algorithms to safeguard against emerging quantum threats [4][5] - Nearly half of early adopters are actively exploring or piloting PQC solutions, with regulatory mandates being a significant driver for this transition [5] Organizational Readiness - Despite the urgency, 30% of organizations are still neglecting the quantum threat, struggling with budget and personnel allocation for cryptographic transitions [6] - The report surveyed 1,000 organizations with annual revenues of at least $1 billion across 13 sectors and countries, with 70% identified as early adopters [7][10]
