- VentureBeat's Pulse Research survey of 107 enterprises found 54% experienced an AI agent security event in the past twelve months — 18% a confirmed incident and 36% a near-miss caught before harm.
- Only 32% of enterprises give every AI agent its own scoped identity, while 69% have credential sharing somewhere in their fleet, correlating with a 63.5% incident rate versus 40.9% for fully-scoped-identity organizations.
- OpenAI's guardrails (51%) dominate the enterprise agent security stack alongside Google and Microsoft cloud controls and Anthropic's managed-agent controls, while dedicated agent-security specialists "barely register," per the survey.
- Only 30% of enterprises sandbox their highest-risk agents — the control that bounds blast radius — while 49% enforce runtime permissions and 47% monitor agent activity, an ordering the report calls "backwards from a defense-in-depth standpoint."
- Satisfaction with provider-native tooling averages 4.2 out of 5, yet a clear majority plan to change tooling within the year and only a third believe their AI defenses are ahead of AI-enabled attackers.
- Incident exposure scales with company size while containment does not: the incident-or-near-miss rate rises from 49% in the mid-market (101–1,000 employees) to 63% at enterprises above 1,000, while sandbox isolation of high-risk agents drops from 35% to 20%.
Why it matters: Most enterprises are running agents on shared credentials (69%) and borrowed provider guardrails, yet 54% have already been hit by an incident or near-miss. With only 30% sandboxing high-risk agents, a single compromised agent carries an enterprise-wide blast radius — and most plan to swap out their security stack within a year.
