Introduction: Why Worry About Quantum Computing Now?
For decades, encryption has been the foundation of digital security. Businesses trust encryption to protect financial records, customer data, intellectual property, and communications. But a powerful new technology—quantum computing—threatens to change the rules.
While fully operational quantum computers capable of breaking modern encryption aren’t mainstream yet, experts warn they are coming sooner than we think. That means businesses cannot afford to ignore the threat. Sensitive data stolen today may be decrypted tomorrow—a concept known as “harvest now, decrypt later.”
In this article, we’ll explore what quantum computing is, why it threatens encryption, what “harvest now, decrypt later” means for businesses, and how BizDefender helps organizations prepare for a quantum-resistant future with Business Identity Theft Protection and Business Fraud Protection.
What Is Quantum Computing and Why Does It Matter?
Quantum computing uses the principles of quantum mechanics—superposition and entanglement—to perform calculations far faster than classical computers.
While today’s encryption algorithms, like RSA and ECC, are mathematically secure against classical computers, quantum computing introduces new risks. Specifically:
- RSA and ECC encryption could be broken in hours or days using Shor’s Algorithm, once large-scale quantum computers become available.
- Data encrypted with today’s standards may no longer be safe in the future.
How Does Quantum Computing Threaten Current Encryption?
Why isn’t encryption “forever safe”?
Current encryption relies on the difficulty of factoring large numbers or solving discrete logarithms—problems that classical computers can’t solve in a practical timeframe. Quantum computers, however, are uniquely suited to solving these problems quickly.
The result? Sensitive business data—financials, trade secrets, employee information, contracts—that may remain valuable for years or even decades could be exposed once quantum computers reach maturity.
What Is “Harvest Now, Decrypt Later”?
“Harvest now, decrypt later” is the strategy cybercriminals are already using today:
- Steal encrypted data now. Attackers breach businesses and exfiltrate sensitive information, even if it’s encrypted.
- Store it until quantum computers are ready. Data may sit in storage for years.
- Decrypt it later with quantum power. Once quantum computing matures, all that stolen data can be unlocked.
For businesses handling long-lived data—such as customer identities, intellectual property, healthcare records, and financial agreements—the risk is especially high.
What Does This Mean for Your Business?
Are small businesses really at risk?
Yes. Hackers aren’t just targeting big corporations. Small businesses are increasingly seen as low-hanging fruit because many lack advanced cybersecurity defenses.
Quantum computing threats add a new dimension:
- Even if your data is encrypted, it could still be stolen today.
- That data could later be used for fraud, identity theft, or corporate espionage.
This is why Business Identity Theft Protection and Business Fraud Protection from BizDefender are so critical—not just for today, but for the next decade.
How Can Businesses Prepare for a Quantum Future?
What steps should you take now?
- Identify high-risk data. What information would still matter 5, 10, or 20 years from now? Think contracts, intellectual property, personal identity data, and financial records.
- Adopt quantum-resistant strategies. The National Institute of Standards and Technology (NIST) is already developing post-quantum cryptography (PQC) standards. Businesses should begin planning migration now.
- Partner with experts. Small business operators don’t have the time or expertise to research cryptographic trends. This is where BizDefender steps in.
How BizDefender Helps You Stay Ahead
At BizDefender, we believe that small businesses deserve enterprise-level protection, made simple and affordable. Here’s how we support long-term security:

Frequently Asked Questions (FAQ)
Q1: When will quantum computers be able to break encryption?
Experts estimate within 10–20 years, but “harvest now, decrypt later” makes it urgent today.
Q2: Should small businesses really worry about quantum threats?
Yes—small businesses are prime targets because attackers expect weaker defenses.
Q3: What is post-quantum cryptography?
It’s a new set of algorithms designed to resist quantum attacks, currently being standardized by NIST.
Q4: What kind of data is most at risk?
Any long-lived sensitive data: customer identities, contracts, intellectual property, and healthcare or financial records.
Q5: How does BizDefender help against quantum threats?
BizDefender identifies high-risk data, protects it with Business Identity Theft Protection and Business Fraud Protection, and helps businesses prepare for a quantum-safe future.
