The recent $1.2 billion acquisition of Elisity by quantum vendor IonQ has certainly stirred the pot, making a lot of business owners ask about quantum cybersecurity hype. For most businesses, including those with advanced IT, quantum threats are still years away from being a practical concern. While post-quantum cryptography (PQC) and quantum key distribution (QKD) are interesting, the immediate focus needs to be on vulnerabilities that attackers are exploiting right now, not theoretical future threats.
I’ve watched this play out for 30 years. Back in the 90s, everyone was convinced ISDN was the future. Then it was ATM, then Frame Relay. Each time, vendors promised a revolution, and each time, the real-world adoption lagged significantly behind the marketing. Today, we’re seeing a similar pattern with quantum. IonQ’s acquisition of Elisity, a company focused on Zero Trust microsegmentation, is a smart business move for them to generate revenue while their core quantum computing business ramps up. But let’s be clear: Elisity’s microsegmentation, while critical for today’s networks, has little to do with quantum threats.
Frank Dickson, a principal analyst at Dickson Research, reported that dividing the acquisition price by Elisity’s 100+ deployments puts the cost at about $13 million each. That’s a steep price for what essentially gives IonQ access to existing enterprise CISO relationships. For you, the business owner or IT manager, that $13 million is far better spent on immediate, tangible security improvements. We’re talking about hardening your network against the phishing attacks, ransomware, and insider threats that are actively targeting businesses every single day.
What real quantum cybersecurity hype means for your business
The reality is, post-quantum cryptography (PQC) runs on classical systems. Brian Jackson of Info-Tech Research Group rightly pointed out that migrating to PQC depends on cryptographic inventory and crypto-agility, not quantum computing expertise. This means understanding what encryption you currently use, where it’s deployed, and how quickly you can swap it out when new standards emerge. It’s a painstaking process, not a magical quantum fix. For instance, the NIST Post-Quantum Cryptography Standardization Project outlines the extensive research and rigorous selection process for these new algorithms, emphasizing a methodical transition.
We’ve seen clients pour money into shiny new tech that doesn’t solve their fundamental problems. I remember a manufacturing client who spent a fortune on a next-gen firewall. Great piece of kit, but their employees were still clicking every suspicious email. The firewall was like putting a steel door on a house with wide-open windows. The focus should always be on the biggest, most immediate risks. For now, those risks are firmly in the realm of classical cybersecurity threats: social engineering, unpatched systems, weak access controls, and poor network segmentation.
Here’s what nobody is talking about: the integration challenges. Justin Greis, CEO of Acceligence, noted that combining IonQ’s quantum capabilities with Elisity’s Zero Trust platform requires “meaningful engineering and execution.” That’s consultant-speak for “this is going to be a nightmare to get working right.” We at CTS have spent decades integrating disparate systems, from Cisco VoIP clusters to Microsoft Azure migrations. Even with mature, well-documented APIs and protocols, it’s rarely plug-and-play. Imagine the complexity when one side is still largely theoretical.
So, what should you do instead of getting caught up in the quantum buzz?
- Implement Zero Trust principles NOW: Elisity’s core offering – microsegmentation – is crucial. Limit each user, device, and application to only the network resources it absolutely needs. Tools like Cisco Identity Services Engine (ISE) or VMware NSX can achieve this today, without new hardware, and without waiting for quantum.
- Fortify your endpoint security: A robust EDR (Endpoint Detection and Response) solution like CrowdStrike Falcon or SentinelOne is non-negotiable. It catches threats before they spread.
- Prioritize employee training: Phishing remains the #1 attack vector. Regular, engaging security awareness training is your cheapest and most effective defense. We use platforms like KnowBe4 and Cofense.
- Audit your cryptographic inventory: Start understanding where and how encryption is used across your organization. This is the foundational work for any future PQC migration, and it will take time.
- Partner with experienced IT: Instead of chasing tomorrow’s headlines, focus on today’s battles. We help businesses secure their networks with proven, practical solutions. Visit our cybersecurity services page to learn more.
Don’t get distracted by what might be coming in 5-10 years. Secure what you have today. The threats are real, and they’re here now.
Frequently asked questions
Is quantum cybersecurity a real threat to my business today?
No, for most businesses, quantum cybersecurity threats are still theoretical and years away from being a practical concern. Focus on existing, proven cybersecurity measures.
What is Zero Trust microsegmentation?
Zero Trust microsegmentation limits each user, device, and application to only the specific network connections it needs, preventing attackers from moving freely across your network if they gain access.
How much should I invest in quantum cybersecurity now?
For most organizations, investment in quantum cybersecurity at this stage is premature. Prioritize current, tangible security improvements like endpoint protection, employee training, and Zero Trust architecture.
What is post-quantum cryptography (PQC)?
Post-quantum cryptography (PQC) refers to cryptographic algorithms designed to run on classical computers but be resistant to attacks from future quantum computers. It's about securing today's data against tomorrow's quantum threats.
