IonQ to Acquire Elisity for Up to $1.3 Billion to Integrate Zero Trust with Post-Quantum Cybersecurity

IonQ announced an all-stock agreement to acquire cybersecurity firm Elisity for up to $1.3 billion. The deal, expected to close in Q4 2026, will integrate Elisity's zero trust platform with IonQ's post-quantum cryptography capabilities. Elisity will continue operating as a subsidiary under its own brand.

OutlookPlausible

IonQ could become one of the first vendors to offer a combined zero trust network access and post-quantum cryptography migration solution, making it easier for enterprises to comply with federal PQC mandates.

IonQ Agrees to Buy Elisity in Cybersecurity Deal Worth Up to $1.3 Billion

IonQ has agreed to acquire cybersecurity company Elisity in an all-stock transaction valued at up to $1.3 billion, with up to $150 million more tied to future performance. The deal expands IonQ's security business at a time when, according to the company, advances in quantum computing and AI are increasing cyberattack concerns. Terms were disclosed to The Wall Street Journal.

OutlookPlausible

IonQ could use Elisity's enterprise network security customer base to offer quantum-era zero-trust services, turning existing security relationships into an early channel for post-quantum migration and risk assessment before cryptographically relevant machines arrive.
