In a previous blog article, we explored the cyber strategy known as “harvest now, decrypt later.” Currently, nation-states are actively collecting encrypted data from governments and businesses worldwide. Their objective is to gather this information and store it with the expectation that future advances in technology will eventually allow them to decrypt it. This creates a potential quantum decryption threat that could compromise decades of sensitive information.

Quantum computing is the technology poised to make that possible. Unlike traditional machines, quantum computers utilize the principles of quantum mechanics to process information at speeds that are impossible with conventional computing. Once quantum computers become powerful enough, they will be able to crack widely used encryption protocols in a matter of minutes. Any organization or country with access to a will be able to quietly unlock previously secure data, making a robust data encryption strategy essential to long-term protection.    

The good news is that the threat is serious but manageable. Solutions like post-quantum cryptography (PQC) are being developed to defend against future attacks and ensure quantum-safe security for sensitive data. There is no overnight fix, but there are four important steps IT and security leaders can take to prepare. Let’s explore.

Step 1: Educate Leadership and Build Awareness

Before your teams can act, leadership must understand the stakes. Quantum decryption threats are not a science fiction scenario. They are real threats that experts believe could emerge within five to ten years, if not sooner. In fact, the danger is already beginning to take shape. Malicious actors are collecting data today with the intention of breaking its encryption in the future.

For executives, this makes quantum a strategic issue that affects long-term security planning, enterprise architecture, and regulatory readiness. Agencies such as NIST have already finalized new encryption standards in anticipation of this shift, highlighting the need for a forward-looking data encryption strategy Boards, compliance officers, and IT governance leaders should be briefed so they can account for quantum preparedness in risk planning.

Organizations that delay action until the threat is obvious may find themselves out of step with emerging compliance expectations and at risk of falling behind in vendor readiness.

Step 2: Classify Your Data and Encryption Methods

Data is no longer stored in one central location. It lives across cloud environments, SaaS platforms, endpoints, backup archives and more. The first step toward defending against quantum decryption threats is understanding where your most valuable data resides and how it is currently protected.

Begin by identifying which data must remain confidential for extended periods of time. That could include:

• Medical records subject to long-term compliance requirements
• Legal documents and intellectual property in regulated industries
• Financial transaction logs or proprietary business plans

Next, review how this data is encrypted. Asymmetric encryption protocols such as RSA, Diffie-Hellman, and elliptic curve cryptography are especially vulnerable to quantum attacks. These algorithms are used in many systems, including authentication mechanisms, VPNs, application communications, and data transmission protocols. A proactive data encryption strategy can help organizations identify where these weaknesses exist and prioritize remediation.

A significant challenge is that encryption methods are not always visible. , many organizations rely on software that contains cryptographic dependencies buried in open-source libraries, firmware, or vendor-provided modules. To uncover these hidden risks, utilize software bill of materials (SBOMs), conduct passive traffic analysis, and consult with internal or external security architects who understand post-quantum cryptography (PQC) principles.    

The combination of data classification and encryption discovery creates a foundation for all future quantum readiness work.

Step 3: Build a Quantum-Ready Roadmap

Once you understand where your risks are, the next step is to develop a plan that reduces your exposure over time. This roadmap should focus on two key areas to minimize the potential impact of a quantum decryption threat.    

1. Transition to Post-Quantum Cryptography (PQC)

NIST has selected several algorithms that are designed to resist quantum-based attacks. These include Kyber for key exchanges and Dilithium for digital signatures. These algorithms are designed to run on classical computers and offer stronger protection against quantum capabilities.

Now is the time to begin testing and evaluating these algorithms in your environment. Consider performance impacts, compatibility with existing platforms, and integration requirements. Some industries are likely to make quantum-safe encryption mandatory, so early testing now may reduce compliance friction later.

2. Explore Quantum Key Distribution (QKD)

QKD enables the transmission of encryption keys in a manner that reveals any interception attempt. Although this technology is promising, it currently requires significant investment and specialized infrastructure. Most organizations will find PQC to be the more practical option in the short term.

As discussed in the podcast, adopting these technologies will take time. It will not be a single update or an overnight migration. The organizations that begin preparing today will be positioned for stronger quantum-safe security when quantum computing becomes a real-world threat.    

Step 4: Evaluate and Engage with Your Vendors

No IT leader can achieve quantum safety alone. Every enterprise relies on external vendors and service providers, which means their level of preparedness will affect your overall security posture.

Ask your vendors the following questions:

• Have you adopted or started piloting NIST-approved post-quantum encryption algorithms?
• Can you share a detailed SBOM that includes cryptographic dependencies?
• What is your projected timeline for PQC support across your product or service portfolio?
• Have you tested Kyber, Dilithium, or other relevant algorithms for compatibility?

As noted in our podcast, many vendors have yet to fully assess their own quantum readiness. That creates business risk. Procurement teams, architecture review boards, and security leaders should begin incorporating these criteria into renewal conversations and RFP processes to ensure a comprehensive approach to security.

Quantum Decryption Is a Future Threat That Requires Present-Day Planning

Encryption will not vanish. It will evolve. The Quantum decryption threat will emerge gradually, without warning. Quantum computers are unlikely to arrive with a public countdown clock. Their impact will be felt quietly at first, as adversaries begin to unlock previously stolen data.

The most prepared organizations will be the ones that take action before headlines appear. If your strategy depends on traditional encryption, your window to assess and adapt is already open. Building toward quantum-safe security now ensures your data and systems remain protected as technology advances.

Imagine for a moment that you just successfully invented the world’s first time machine, a device so powerful it could alter the course of history, economics, and even the fate of nations. The immediate question might be: Would you publicize your breakthrough or keep it quiet?

After all, going public would instantly attract the attention of governments and powerful organizations. They might seize your invention for national security reasons or pass laws making private ownership illegal. Aside from notoriety, there would be no real advantage in drawing attention to your achievement.

Now consider the things you could do with such a device. You could travel back in time and invest in companies like Apple or Amazon at their inception to amass unimaginable wealth without attracting attention. You could correct past mistakes or influence key historical moments to steer the world in a different direction. The potential power of such capabilities would far outweigh any recognition as its inventor.

The Advantage of Being First

At the very least, any formal announcement of a successful time machine would trigger a global race as every government, corporation, and research institution poured resources into building their own. Any lead you had would erode quickly. The world might descend into chaos as everyone began trying to rewrite history for their own benefit.

In track and field, the first one out of the blocks has an advantage. But in technology, the first one usually doesn’t say a word, especially when the power at stake is total.

A Familiar Pattern: Quantum Computing

Chances are you’ve heard of . It’s not just hype. It’s a radically different approach to computation based on quantum mechanics…concepts like superposition and entanglement that, unless you studied physics past high school, probably feel like they belong in a Marvel movie.

The main thing to know? Quantum computers, once they reach a critical size and stability, could break the asymmetric encryption algorithms that secure the modern digital world—RSA, Diffie-Hellman, Elliptic Curve. These algorithms underpin everything from email to banking, VPNs to authentication systems.

Imagine If Nothing Was Secret

If you had a powerful enough quantum computer, you could decrypt almost anything. Think about that: every secured government communication, every medical record, every financial transaction, every corporate trade secret could be unlocked.

It’s not hard to see why the first nation (or group) to get there won’t shout about it. Instead, they’ll quietly collect power, insight, and leverage.

Harvest Now, Decrypt Later

Here’s where things get particularly interesting and relevant, right now.

Say you’re a adversary, and you believe quantum computers will be ready in 5 to 10 years. Why wait to collect data then? Instead, you start sweeping up encrypted communications now. You can’t read them today, but you store them, knowing that tomorrow’s quantum machines might make them transparent.

That’s what “Harvest Now, Decrypt Later” means. And it’s not theoretical. Cybersecurity agencies in the U.S. and Europe have warned that nation-state adversaries are already deploying this tactic. They’re not just hoarding missile secrets and embassy chatter…they’re grabbing trade deals, source code, patent applications, and diplomatic correspondence.

Some of this data might age out and become useless. But for anything long-lived such as nuclear facility layouts, industrial R&D, legal contracts, or biometric identities, it could still matter years from now.

What This Means for IT Leaders

Even if you don’t manage security directly, you likely oversee the infrastructure, systems, and strategy that rely on public-key cryptography. That includes:

• VPNs, TLS, HTTPS, and S/MIME
• Federated identity and access controls (SAML, OAuth)
• Application backends and APIs with embedded keys
• Encrypted archival data with multi-decade retention policies

Your entire architecture is likely built on encryption you assume is unbreakable. That assumption is now on a timer.

So what should you do?

1. Inventory Where Asymmetric Encryption Is Used

Start by identifying which systems use asymmetric encryption, especially during key exchange. These are your weak links. This is harder than it sounds. Many apps bury crypto inside third-party libraries or firmware. But it’s critical groundwork.

Modern tools for software bill of materials (SBOMs) and asset discovery can help. WEI and our partner Pulsar Security recommend using passive network analysis to identify TLS handshakes, public key cryptography calls, and encrypted tunnels that may be vulnerable once quantum machines come online.

2. Think Critically About Long-Term Data

Ask your teams: “What encrypted data are we storing today that still needs to be secure in 2035?”

If you’re in healthcare, that could be patient data. In financial services, it might be transaction logs or payment histories. In manufacturing, it could be intellectual property or confidential vendor contracts.

These datasets should be prioritized for post-quantum crypto adoption.

3. Begin Experimenting with Post-Quantum Cryptography

Here’s the good news: you don’t need a quantum computer to defend against one. NIST (National Institute of Standards and Technology) has selected a new class of “quantum-safe” encryption algorithms, like Kyber and Dilithium, that run on traditional hardware.

We’re entering a phase much like Y2K. The problem is real, the timeline is tight, but the tools to solve it already exist.

What’s the Timeline for Quantum-Safe Tools from Cloud and Tech Vendors?

The major cloud and platform providers have already started integrating quantum-resistant cryptography into their services. Microsoft, Google, and AWS are offering early access to new algorithms recommended by NIST, including Kyber and Dilithium, within their key management, TLS, and VPN ecosystems. Microsoft has introduced hybrid post-quantum TLS support in Windows 11 and . AWS is piloting quantum-safe encryption within its KMS and CloudHSM environments. While these capabilities are not fully production-ready, they are available today for testing and development use.

This is important because shifting to post-quantum cryptography is not a quick swap. It will require interoperability testing, vendor engagement, and careful alignment across infrastructure and application layers. The organizations that begin experimenting now will be far better positioned when quantum risks accelerate. IT leaders do not need to roll out a full deployment today. What matters is understanding how your environment will respond when the time comes to transition and knowing which tools and partners are already one step ahead.

The Future Isn’t All Risk

Quantum computing isn’t just a threat. It also promises breakthroughs in drug discovery, advanced materials, and climate forecasting. And it may even help build better encryption.

But for now, its first major impact will likely be felt in how we secure data and whether we’re prepared to protect it.
