Are Businesses Ready To Face Rising Quantum Computing Security Threats?

Recent developments in quantum computing suggest significant changes in the way digital information is processed. Quantum computers utilize qubits, which can represent multiple states simultaneously, thereby reducing the number of operations required for certain calculations. This advancement has implications for energy consumption in the digital economy, as discussed at the World Economic Forum's Annual Meeting.

An analysis by Bain indicates that quantum computing has progressed to a point where quantum machines are more stable and dependable. This advancement could significantly reduce the time required to break encryption that secures everyday digital activities. The availability of large-scale quantum computers poses a potential threat to the security of payments, company emails, and internal systems, as they could quickly render current encryption methods ineffective.

Bain's Post Quantum Cryptography Survey 2025 reveals that 71% of executives anticipate quantum attacks within the next five years, with nearly one-third expecting these attacks within three years. Approximately 65% of business, IT, and cybersecurity leaders acknowledge that quantum computing will elevate cyber risks within their organizations.

Only 11% of surveyed companies believe their current defenses will remain effective over the next five years. Bain's analysis emphasizes that quantum computing will render today's cryptography obsolete, impacting all areas of IT infrastructure. Sensitive information, including defense designs, chip architectures, and government secrets, is at risk of being compromised when quantum systems reach full scale.

Organizational Preparedness for Quantum Risks

Despite increased awareness, Bain's research indicates that only about 10% of companies have a funded roadmap, supported by senior leadership, to address quantum risks. Many executives expect suppliers, regulators, or peers to initiate necessary actions.

Bain's analysis highlights that supplier updates often address only specific products, leaving gaps in company technology. The responsibility for these gaps remains with the organization, along with potential fines, legal action, and operational damage.

A lack of internal visibility exacerbates the issue. According to Bain's survey, only 52% of companies understand where sensitive data resides within their systems, and only 38% maintain a comprehensive record of cryptographic standards in use. This lack of knowledge hampers efficient encryption replacement efforts.

Quantum computing threatens common cryptographic methods such as RSA, Diffie-Hellman, and elliptic curve cryptography. It also reduces the time required to weaken protections like AES. Bain's analysis suggests that quantum systems, when paired with AI , could expedite the discovery of software vulnerabilities and support more targeted fraud. Bain warns that existing defenses, built on assumptions about computational difficulty, may collapse rapidly.

Strategies for Addressing Quantum Risks

Organizational leadership must assume direct responsibility for quantum risk management. Bain advises against relying solely on third parties, as this approach ties security to external priorities and schedules.

Risk management should begin with mapping cryptographic exposure. This includes understanding which algorithms are in use, where cryptographic keys are stored, the duration for which data requires protection, and which systems are most vulnerable. Bain's research indicates that only 12% of companies consider quantum readiness a critical factor when purchasing new technology .

Despite the impending risks, 90% of executives have not allocated budgets or resources to prepare adequately. Bain's analysis underscores the importance of proactive planning and leadership support in the coming months. Delays in preparation increase costs and leave organizations vulnerable as quantum capabilities advance towards real-world application.
