What​‍​‌‍​‍‌​‍​‌‍​‍‌ if the most confidential data of your company, the kind of information that includes customer records, contracts, and financial information, were stored in ciphers that looked unbreakable? As of today, that is the case. However, imagine a device that could unlock those ciphers in a matter of minutes. This is the imminent reality of quantum threats to encryption, where advances in quantum computing could compromise the very security of digital data.

A quantum computer is not a concept of a story set in the future. It’s a device with capabilities that allow it to do operations at an incredible speed with respect to a regular computer. A 2024 Gartner report states, “By 2029, advances in quantum computing will make conventional asymmetric cryptography unsafe to use”. This is a more generalized but still urgent warning about the impending threat. The current encryptions, like RSA and EC, are based on mathematical problems that are extremely difficult for normal computers to solve. However, in the case of quantum computers, Shor’s algorithm and other similar algorithms can efficiently solve these problems, thereby making the entire security infrastructure of digital communications, data storage, and transactions vulnerable.

Why Businesses Should Act Now

You might come up with a reason such as, “Quantum computers are not coming anytime soon, so why should I be worried?” The “harvest now, decrypt later” strategy should make us think differently: adversaries may already be saving encrypted information that they will decrypt once quantum computers are fully operational. Data that is supposed to remain confidential for the next several years, for example, medical records, contracts, or financial archives, will be at risk of exposure if institutions take a wait-and-see approach.  In a July 2025 report, Keyfactor and Wakefield Research found that 48% of organizations surveyed were not prepared for post-quantum cryptography (PQC) threats.

Besides, encryption is what keeps trust going. The loss of encryption security is not only an IT issue, but it may also jeopardize compliance, the trust of customers, and business continuity in general. Regulators and industry bodies are not waiting for the perfect moment to jump on the bandwagon of proactivity. Europol, for one, recommends that banks get ready for threats from quantum, whereas recent surveys reveal that nearly 50% of companies are still not prepared to confront the challenge.

Steps to Quantum-Resilient Security

Organizations should not be scared of the quantum era. Instead, they must formulate a plan. Here is a feasible strategy:

1. Inventory and assess cryptography: Determine exactly which hardware or software is based on weak algorithms, how long the stored data is going to be viable, and where sensitive data streams lead. Such a scrutiny will serve as the cornerstone of the gradual transition plan.

2. Evaluate risk and prioritize: Locate the most important pieces of information and the systems with your data retention policy clauses or that are subject to regulation. Valuable assets must become the first to be onboarded for migration. 

3. Implement crypto-agility: Crypto-agility means that an enterprise can change its encryption methods quickly and easily. Introduce hybrid schemes where a classical cipher coexists with a quantum-safe one, thus providing both security and compatibility during the transitional phase.

4.  Introduce Post-Quantum Cryptography (PQC): PQC algorithms are being standardized by organizations such as NIST. Enterprises may initiate trial runs of the implementation in certain areas, i.e,.The confidential email, key exchange, or APIs to evaluate the performance and interoperability while resourcefully preparing for full-scale transition. As per Gartner, Governments are already issuing mandates and legal frameworks for organizations to put in place a post-quantum cryptography strategy.

5. Improve overall security stance: The quantum risk layer is just that, a layer on top of the existing cybersecurity groundwork. The company should still be implementing zero-trust models, rigorous identity and access management, encryption in transit and at rest, as well as logging and monitoring.

6. Involve stakeholders: The board, legal, compliance, operational departments, and vendors are a few of the many stakeholders who contribute to this effort. Delivering clear messages in a language that business people understand, for instance, customer trust, risk, or regulatory compliance risk, makes it easier to get the approval required. 

7. Keep an eye on the changing scene: Be informed about the latest research in quantum computing, ever-changing cryptography standards, and guidance from regulators. Being proactive allows you to keep up with evolving technology and the threat landscape. 

Industry in Focus

What if a digital payments service provider uses ECC for key exchangers and retains transaction logs for seven years? By mapping out their cryptography estate, identifying high-value assets, PQC integration as a pilot, and reporting their progress to the management level, they basically turn the quantum threat, which until now was only a theory, into an imminently manageable, orderly roadmap. This way of doing things proves that getting ready is not a reaction, but rather a strategic move. 

Essential Insights

Impacts of quantum computing on encryption currently in use are a very difficult problem to solve within the next few years.

It is only right to take steps early when there is a need to keep data for a long time and meet regulatory requirements.

Several of the measures to be taken proactively are to take an inventory of the systems, the data that has the most value, implement crypto-agility, and perform PQC resilience tests so that an organization cannot be defeated.

It is a problem that all organizations have to deal with, not just banks or government agencies.

Cooperating with cross-functional teams and following the latest trends will make this period of change easier for you.

Businesses that decide to act now are not only in a position to safeguard the integrity of the data they possess but also to keep their customers’ trust, comply with regulations, and be at the forefront of the competition. Think of quantum readiness as a strategic move rather than a distant technical problem. Your encryption is not just for today – it is about staying secure when quantum arrives.

Conclusion

Quantum computing is no longer just a distant idea – in fact, it is quite rapidly moving towards a point where it could have a major impact on the security bases of companies all over the globe. Although the risk to encryption is quite serious, it is still manageable if dealt with carefully. Firms that bravely tackle the challenge by checking their cryptographic systems, concentrating on the most valuable data, pursuing crypto-agility, trying post-quantum cryptography, and talking to stakeholders can turn such an intangible threat into a well-organized, tangible plan.

Being prepared now means more than just protecting data – trust is maintained, compliance is guaranteed, and resilience is strengthened for the long term. Those who regard the coming of the quantum era as an opportunity to get ready rather than a call for action will be the ones experiencing both security and trust in the future. In brief: don’t merely wait for the advent of quantum to act – make your moves today that will keep you safe tomorrow.

FAQs

Q1: What are quantum threats to encryption?

Quantum threats are situations in which quantum computers could cause by breaking the cryptographic techniques that are currently used, in particular, RSA and ECC, thus compromising the security of data, communications, and digital signatures.

Q2: When should businesses begin preparation?

The time to prepare is now. As a switch to quantum-safe cryptography cannot be done in one night, being both difficult and long, data protection may be very much needed for a long time to come.

Q3: What is Post-Quantum Cryptography (PQC)?

PQC refers to encryption algorithms designed to resist quantum computer attacks. Those algorithms may either replace the current ones or run alongside them, and a draft by NIST is waiting for its final approval for that.

Q4: Is the threat relevant to small businesses?

Definitely. Any organization handling sensitive data or being heavily dependent on encryption must certainly consider whether it is a possible target for quantum attacks, regardless of its size.

Q5: What are the first steps to prepare?

Creating a record of your installations, prioritizing high-value data, implementing crypto-agility, performing a PQC pilot, and receiving stakeholder support are the steps that will most likely assist you in devising a well-planned ​‍​‌‍​‍‌​‍​‌‍​‍‌​‍​‌‍​‍ׁ​‍​‌‍​‍ׁ​strategy.
