AI Agent Security Gap: 54% of Enterprises Have Already Had an Incident, Yet Most Still Let Agents Share Credentials
A VentureBeat survey of 107 enterprises reveals that 54% have already experienced an AI agent security incident or near-miss. Despite this, most companies still let agents share credentials, only a third give each agent its own scoped identity, and just 30% isolate their highest-risk agents. The security stack is largely borrowed from model providers and hyperscalers rather than purpose-built for agents, and spending remains a thin slice of the security budget.
