Founded nine years ago, Armis offers security software that protects critical infrastructure across Fortune 500 companies as well as national, state, and local governments. The platform focuses on identifying and safeguarding unmanaged and IoT devices, helping large organizations reduce cyber-risk across their operational technology environments. Armis reports annual recurring revenue of $300 million and is targeting $500 million in ARR while becoming cash-flow positive ahead of an IPO. Management says the company is already running with public-company discipline, meeting quarterly financial targets. Recent inbound interest included seven acquisition offers—one reportedly a $5 billion bid from Thoma Bravo—which the company declined. Instead, Armis raised fresh capital, increasing its valuation to $6.1 billion and underscoring its commitment to go public in late 2026 or early 2027.
