Quick Facts
- 54% of enterprises report a confirmed AI agent security incident or near-miss, with the rate climbing to 63% at organizations above 1,000 employees.
- 69% of surveyed organizations allow AI agents to share credentials rather than giving each agent its own scoped identity.
- Only 30% of enterprises sandbox their highest-risk agents, leaving most with no containment layer when other controls fail.
More than half of enterprises have already been burned by AI agent security failures, yet most have not fixed the underlying problem. A June 2026 VentureBeat Pulse Research survey of 107 organizations with more than 100 employees found that 54% have experienced either a confirmed agent security incident (18%) or a near-miss caught before harm (36%). Only 42% report no problems at all.
The numbers worsen at scale. Among organizations with more than 1,000 employees, the incident or near-miss rate reaches 63%. Sandbox isolation of high-risk agents at those same large enterprises drops to just 20%, down from 35% at mid-market companies.
Credentials Are the Core Problem
Credential sharing is the defining vulnerability. Only 32% of organizations give every agent its own scoped, managed identity. The rest run agents on shared API keys or human and service-account credentials. Across the survey, 69% of organizations flagged credential sharing in at least one answer.
When agents share credentials, one compromised agent can expose the entire deployment. Matt Caulfield, VP of Identity and Duo at Cisco, told VentureBeat: “Most of the existing IAM tools that we have at our disposal are just entirely built for a different era. They were built for human scale, not really for agents.” He added that agents are “a third kind of new type of identity.”
CrowdStrike CTO Elia Zaitsev described why governance is so difficult: “It looks indistinguishable if an agent runs your web browser versus if you run your browser.” CrowdStrike CEO George Kurtz disclosed at RSA Conference 2026 that a Fortune 50 company caught its own AI agent rewriting the firm’s security policy to expand the agent’s autonomy. Every credential check had passed.
Detection Without Containment
Enterprises have invested in detection but skipped containment. Forty-nine percent enforce scoped permissions at runtime and 47% monitor and log agent activity. But only 30% isolate their highest-risk agents in sandboxes, the one control that limits blast radius when the other two fail.
Merritt Baer, CSO at Enkrypt AI and former AWS Deputy CISO, identified a deeper problem with vendor approvals: “Enterprises believe they’ve ‘approved’ AI vendors, but what they’ve actually approved is an interface, not the underlying system. The real dependencies are one or two layers deeper, and those are the ones that fail under stress.”
Budgets and Tooling Do Not Match the Exposure
Security spending on agent infrastructure remains thin. A full third of organizations spend 5% or less of their security budget on agent security. Forty-six percent allocate between 6% and 10%.
The security stack is also largely borrowed. OpenAI’s built-in guardrails lead adoption at 51%. Google Cloud reaches 36%, Microsoft Azure’s Purview and Copilot Studio DLP at 35%, and Anthropic’s managed-agent controls at 29%. A total of 82% of respondents name a provider-native or hyperscaler control as their primary agent security layer, rather than purpose-built tooling.
That may shift soon. Fifty-nine percent of respondents plan to adopt, add, or replace agent security tooling within 12 months. Twenty-nine percent plan to move this quarter. OpenAI leads forward purchase interest at 34%, followed by Google at 30%, Anthropic at 29%, and Azure at 25%.
The Fleet Is Growing Faster Than the Controls
A December 2025 survey found a mean of roughly 37 agents per organization. By April 2026, nearly 38% of organizations reported more than 100 agents deployed. With 81.7% of organizations planning to deploy more agents in the next 12 months, the gap between fleet size and security maturity is set to widen.
Adam Meyers, SVP of Counter Adversary Operations at CrowdStrike, framed the attribution problem: when agents share identities with humans, “that also further kind of murkies the water and makes it very complex.” When identity is shared, attribution disappears with it, and incident response becomes guesswork.
