The emergence of quantum computing poses a significant threat to modern encryption standards, with the potential to render widely used cryptographic protocols obsolete. To mitigate this risk, organizations must transition to post-quantum cryptography (PQC), a process that requires technical, operational, and strategic adjustments. However, the pace and approach to adoption vary across industries and organizational size, influenced by both external pressures and internal capabilities. This study employs a mixed-methods approach, incorporating 14 expert interviews and survey responses from 37 cybersecurity professionals to examine the factors driving and inhibiting PQC adoption. The findings reveal that while regulatory mandates play a role, organizations are increasingly guided by risk exposure and reputational concerns. Key challenges include resource constraints, reliance on third-party vendors, and the complexity of cryptographic inventory assessments and legacy systems. Despite these challenges, the study found that PQC adoption will accelerate as risk awareness grows and implementation guidelines become available. It emphasizes the importance of a strategic, resilience-focused approach to cybersecurity, incorporating cryptographic agility, continuous assessments, and hybrid encryption solutions to navigate the evolving threat landscape.

Quantum computing has emerged as a potential long-term challenge to the cryptographic algorithms that currently secure digital financial systems. As financial institutions rely extensively on cryptography to protect communications, transactions, authentication processes, and sensitive information, the prospect of quantum computing has raised concerns about the future security of existing cryptographic infrastructures. This has created a need to better understand how organisations perceive and approach the transition toward post-quantum cryptography (PQC). This study explores how financial organizations in the United Arab Emirates perceive and approach the transition toward PQC. Guided by the Technology–Organization–Environment (TOE) framework,the study examines how technological, organizational, and environmental factors influence organizational perspectives and approaches toward future cryptographic transition. A qualitative research design was adopted using semi-structured interviews with nine participants in cybersecurity, technology, governance, and compliance roles across banks, financial service providers, payment organizations, and a regulatory authority within the UAE financial sector. The findings show that awareness of quantum-related risks is increasing across the sector; however, most organisations remain in the early stages of assessment and monitoring. Organisational approaches were shaped by technological, organisational, and environmental factors, including cryptographic visibility, governance, resource constraints, regulatory expectations, international standards, and ecosystem coordination. The study concludes that financial organisations in the UAE recognise PQC as an important future cybersecurity challenge but currently approach the transition through awareness-building, assessment, and monitoring rather than active implementation.Organizational responses were shaped by technological, organisational, and environmental factors, indicating that PQC transition extends beyond a purely technical challenge.
The rapid advancement of quantum computing poses a significant threat to classical cryptographic methods such as RSA and ECC, which underpin corporate data protection strategies worldwide. This research investigates the adoption and implications of Post-Quantum Cryptography (PQC) in corporate environments through doctrinal analysis of regulatory standards (NIST FIPS 203–205, NSA CNSA 2.0) and non-doctrinal insights from industry surveys and market reports. Despite growing awareness—69% of corporations recognize quantum threats—only 5% have implemented PQC solutions. The paper presents empirical data illustrating global market trends (projected CAGR ~37%) and evaluates sectoral preparedness, particularly within finance and government. Case studies from companies like Commvault, Apple, and NXP demonstrate early adoption, while challenges remain around integration complexity, cryptographic agility, and regulatory lag. The findings emphasize the urgency of a proactive shift towards hybrid encryption models, procurement reforms, and sector-specific PQC readiness frameworks. This research concludes that strategic, agile adoption of PQC is critical to safeguarding long-term corporate data confidentiality in the approaching quantum era.
