Quantum computing companies have spent years promising to break today's encryption someday. IonQ apparently decided it would rather also sell you the locks. It's a bit like a locksmith who moonlights as an escape artist — confusing at first, but honestly a pretty smart business model.
A $1.3 Billion All-Stock Security Play
IonQ announced on October 12 that it will acquire Elisity, a Zero Trust security company, for up to $1.3 billion paid entirely in IonQ stock, including up to $150 million in performance-based earnouts. The deal is expected to close in the fourth quarter of 2026, subject to regulatory approval, and Elisity will keep operating under its current leadership.
Founded in 2019, Elisity provides identity-based access controls for users, devices, workloads, and — fittingly for 2026 — AI agents and other non-human identities. Its IdentityGraph correlates identity, asset and risk data to decide who gets access to what, and its policies are enforced independently of the underlying network gear. Elisity reports more than 100 customer deployments, revenue and customers doubling year over year, and zero churn among deployed customers.
Quantum-Safe Is the New Table Stakes
The logic: IonQ already sells post-quantum cryptography and quantum key distribution, and Elisity brings enterprise-grade policy enforcement and a sales channel into a microsegmentation market the companies peg at over $10 billion. Combine the two and you get a pitch for networks that are both Zero Trust and ready for the day a quantum computer can crack today's public-key encryption. Elisity's leadership framed it simply: customers "need to prioritize post-quantum cryptography initiatives."
The part most headlines skip is that the hard work isn't buying shiny quantum-safe tech — it's knowing what cryptography you're running in the first place. Industry discussions this week flagged gaps in FIPS-validated modules and full cryptographic inventories as ongoing hurdles. Most organizations can't list every TLS library, certificate and API key in their stack, let alone plan a migration. Meanwhile, the "harvest now, decrypt later" threat means data stolen today could be readable tomorrow.
Quantum-safe security won't arrive as a single switch you flip. It starts with a boring spreadsheet of everything that encrypts anything — and the companies that start that spreadsheet now will be glad they did.
If you have no idea which certificates, libraries and integrations are quietly holding your website's security together, our team can help you build that inventory before the post-quantum deadline sneaks up — start the conversation here.
