AI agent security: Cyera buys Oasis Security in a one billion dollar deal
The cybersecurity firm bets big on protecting machine identities as autonomous agents spread across companies.
Securing AI agents, the software that acts on its own inside company systems, is becoming one of the most contested arenas in cybersecurity. On July 28, 2026, Cyera announced the acquisition of Oasis Security for roughly one billion dollars, a deal that shows how high the stakes have risen.
The terms
According to reports, the agreement is worth close to one billion dollars, with about 700 million in cash and the rest in shares. Oasis Security specializes in managing non-human identities and agent access, technology meant to bring visibility and control over what these autonomous programs do inside critical systems. By acquiring Oasis, Cyera aims to unite data security and identity security into a single platform built for the rise of agents.
A booming sector
The financial backdrop is telling. Cyera had just raised 600 million dollars at a 12 billion valuation, and Oasis had closed 120 million in Series B funding in March. This is Cyera’s third acquisition in 2026, and the deal is expected to close in the third quarter, subject to regulatory approval. More broadly, AI-security startups have raised record sums since the start of the year, riding the same wave.
Why the frenzy
As AI agents gain access and run tasks without constant human oversight, they create new attack surfaces. These machine identities must be tracked, their actions logged, their permissions governed. That is exactly what players like Oasis promise to handle, which explains the appetite of cybersecurity giants.
The takeaway
Agent automation unlocks huge productivity gains, but it shifts the security question onto new ground: non-human identities. For any organization deploying AI, it is a topic to factor in now.
