Quantum computing threatens traditional encryption faster than many businesses expect.
Sensitive data stored today may be decrypted in the future using quantum machines.
Organizations must begin transitioning to quantum-safe security strategies now.
Quantum computing has existed within theoretical or laboratory practices for years. Advancement in research has reduced the gap between present-day applications and practical applications. Governments, technology companies, and research organizations have begun to invest hundreds of millions of dollars into quantum technologies. As this investment increases, there is an increasing concern among cybersecurity specialists about whether or how long current encryption methods will remain secure against the powerful computational capabilities.
What does the pending threat of quantum computing mean to commercial entities? When will we reach a point where quantum computers will be able to break many commonly used methods of symmetric and asymmetric key encryption? Affected data would include financial records, proprietary business information, personal identification and payment information that may be maintained as backups, or even any other data that is protected through existing encryption solutions.
The threat is about time, preparation, and foresight. Organizations that assume quantum risk is still decades away may find themselves dangerously behind. Understanding what quantum risk is and how to prepare has become a necessity. Let's take a look at the broader picture.
Quantum risk describes the risk that the future emergence of quantum computers is going to be able to break the cryptographic systems that we currently use to protect our digital data. The majority of encryption algorithms are secure as they depend on solving hard mathematical problems.
Quantum computers process information in a different manner than classical computers. Using quantum bits or qubits, quantum computers can perform multiple evaluations of possible solutions simultaneously. In practical terms, encrypted emails, financial transactions, and stored data could become readable once powerful quantum systems emerge.

There is a widespread misunderstanding that the importance of quantum risk only applies at the point that large-scale quantum computers are in existence. The real threat exists before quantum computers ever come into play.
Many in cybersecurity have pointed to the “harvest now, decrypt later” strategy for hackers. They can steal encrypted data today and hoard it until they have quantum computers. This presents a significant threat to industries which have long data retention periods, such as banking, healthcare, government and legal services.
Once encrypted data has been disclosed as a result of breaking all-known encryption techniques, there is no way to recover it. Once exposed, any sensitive historical data will be forever unprotected.
Quantum risk is universal across all forms of digital business. However, certain industries carry a higher level of risk. Banks and financial organizations can be heavily impacted by quantum risk as it requires secure transaction processing and identity verification. The healthcare industry also faces the same level of risk, as patient information should remain confidential for years after collection.
Technology companies are also at an increased level of risk as it should protect intellectual property that creates their competitive advantages.
This threat also applies to mid-size companies. These organizations have valuable supply chain data, customer records, and electronic communications that attackers can utilize in the future.
With increasing regulatory scrutiny, organizations could face penalties if they do not implement quantum-safe standards in a timely manner.
The solution involves strategic planning. Cybersecurity leaders continue to push for post-quantum encryption and decryption solutions that will protect against quantum-based cyber attacks.
Governments and organizations around the world are actively engaged in creating this shift to post-quantum security. Companies should analyze their existing use of encryption, understanding how long those encryptions remain valid, and testing available quantum resistant algorithms within non-critical infrastructures.
Preparation includes vendor evaluation, education for employees, and planning for long term capital for cryptography enhancements. This transformation will take place over a number of years.
When we consider quantum-safe encryption, we need to take into account that there will likely be some performance costs and may also require significant complexities in terms of implementation. There also might be interoperability problems given the nature of new algorithms. Enterprises should find a way to balance innovation and operation stability.
There also exists ambiguity concerning the timeline predicting when quantum computers would be considered fully operational. The risk is actually associated with waiting for certainty.

Quantum computers have created endless opportunities, but also challenges the foundation of the digital trust. Quantum risk is more about taking on responsibility than speculation for organizations.
Companies that get started now will have greater flexibility and the ability to feel confident in moving into the future. Many organisations will find that they will be facing quantum risk much sooner than they think. Fear does not provide a solid excuse for avoiding preparing for quantum risk; instead, companies should focus on foresight and strategic planning.
What is quantum risk in cybersecurity?
Quantum risk refers to the possibility that future quantum computers could break today’s widely used encryption methods, exposing sensitive digital data.
Why is quantum computing a threat to current encryption systems?
Quantum computers use qubits that can evaluate multiple solutions simultaneously, making them capable of solving complex mathematical problems that classical encryption relies on for security.
What does “harvest now, decrypt later” mean?
It describes a strategy where attackers steal encrypted data now and store it until quantum technology advances enough to decrypt it later.
Should mid-sized businesses be concerned about quantum risk?
Yes, mid-sized companies often store valuable customer, supply chain, and proprietary data that could become targets for future quantum-enabled attacks.
How can businesses start preparing for quantum threats today?
Organizations can begin by auditing current encryption systems, testing quantum-resistant algorithms, evaluating vendors, and planning long-term cryptographic upgrades.
