Last week I posted about quantum computing and why it's a real threat to business data security. A lot of people had the same question:
"Okay, I get it. But what are we supposed to DO about it?"
Fair question. The answer has a name: post-quantum cryptography. And it's not as complicated as it sounds.
Here's the simplest way I can explain it.
Right now, the encryption that protects your email, your banking, your VPN, your cloud files — it all works because it's built on math problems that regular computers can't solve fast enough to be useful. That's what keeps the bad guys out. Your data is technically visible, but cracking the math would take thousands of years. So nobody bothers.
Quantum computers change that equation. They solve those specific math problems fast. Really fast.
So the smartest cryptographers on the planet spent eight years building new encryption algorithms based on completely different math. Math that neither regular computers NOR quantum computers can crack efficiently.
That's post-quantum cryptography. New locks that quantum keys can't open.
And it's not theoretical. NIST — the U.S. standards body — finalized the first three standards in August 2024. Google already has it built into Chrome. Microsoft has rolled it into Azure and Windows updates. Cisco is shipping quantum-safe firewall firmware later this year.
Here's what the timeline looks like:
→ January 2027: All new U.S. national security systems must use quantum-safe encryption
→ 2030: All existing applications must be migrated
→ 2035: Everything must be quantum-resilient. No exceptions.
Canada has its own deadlines — federal departments had to submit migration plans by this month.
"But I'm not the government." I hear you. But here's the thing — your cyber insurance will start asking about this. Your bigger clients will require it in vendor assessments. And the tools you already use — Microsoft 365, Chrome, your firewall — will all ship with PQC built in through normal updates.
The key is making sure you're not running old, unsupported systems that will never get those updates. If you're still on Windows 10, or an aging server with no upgrade path, you're not just behind on today's security. You're locked out of tomorrow's.
That's exactly the kind of thing proactive IT management catches before it becomes a crisis.
At NICS we're already building post-quantum readiness into our technology planning for clients. If you missed last week's post on why quantum computing matters for your business, scroll back on our page — it's worth the read.
