The acquisition brings together IonQ’s post-quantum cryptography (PQC) and quantum key distribution (QKD) capabilities with Elisity’s enterprise zero trust technology platform. On a combined basis, IonQ will benefit from an expanded cybersecurity platform that uncovers and protects against present LLM and emerging quantum threats.
Elisity builds on IonQ’s expanding quantum security offerings with a high-growth enterprise security business, zero trust technology platform, and team of industry leaders led by cybersecurity expert Chief Executive James Winebrenner.
Elisity has more than 100 global customer deployments and deep CISO and security community relationships. To that end, Elisity will provide IonQ with expanded channels to bring its PQC, QKD and quantum computing offerings to market. They will aim for enterprise and government networks, opening up the more than $10 billion microsegmentation opportunity with double-digit CAGR to IonQ.
“With Elisity and its team as part of IonQ, we are in the position to help customers protect critical infrastructure and enterprise networks throughout the transition to the quantum era,” said Niccolo de Masi, chairman and chief executive of IonQ. “As I said first, Q-Day is coming much faster than predicted. IonQ is offering its customers a vertically integrated full-stack quantum platform across quantum computing, networking, sensing and cybersecurity.”
“Our customers need to prioritize post-quantum cryptography initiatives while securing existing assets to keep essential operations running,” said Winebrenner, chief executive of Elisity. “With IonQ, we will be optimally positioned to partner with them to modernize their crypto-agility programs, accelerate post-quantum cryptography capabilities while advancing their holistic zero trust posture and deploy hybrid-cybersecurity solutions today that are prepared for the quantum future.”
The transaction should close in the fourth quarter of this year.
