Share one API key across five AI agents, and a single compromised agent inherits the reach of all five. The attacker immediately benefits from the accumulated permissions of every workflow that the key touches. The forensic trail goes cold at the credential level because five agents on one account leave no record of which agent did what.
Sixty-nine percent of enterprises run agents with credential sharing somewhere in their deployments, according to VentureBeat’s June 2026 at close — a deal it of runtime authorization platform SGNL and, by June 15, non-human identity specialist Astrix Security on May 4 for a reported , the event in Menlo Park next week (July 14-15) focusing on enterprise autonomous agents.
Forty-five percent are final decision-makers for AI purchases. The sample skews mid-market, so read the numbers as the view from organizations adopting agent security right now rather than from the largest enterprises.
More than half of respondents, 54%, have already had an agent security incident or near-incident. Eighteen percent confirmed an incident, and thirty-six percent caught a near-miss before a breach. Security teams are stopping most of these events at the last control point in the chain, but the rest of the data shows how thin that margin is.
Your agents are sharing credentials
Only 32% of enterprises give every AI agent its own scoped, managed identity. Nearly half (48%) report that some agents have scoped identities, while many still share credentials. Another 32% say agents mostly run on shared API keys or borrowed human and service-account credentials. The survey question allowed more than one selection, and 24 of the 107 respondents chose multiple options — which is why the three categories sum to 112%. Deduplicated by respondent, 74 organizations, or 69%, flagged credential sharing in at least one answer.
One number explains why the acquisitions target this layer. A shared credential converts a single compromised agent into many, and . "Observing actual kinetic actions is a structured, solvable problem," Zaitsev said. "Intent is not." CrowdStrike's Falcon sensor walks the process tree on an endpoint and tracks what agents did, not what agents appeared to intend. A scoped identity and an isolation boundary give that sensor something to track, while a shared credential on a bundled guardrail does not.
Cloud security went through the same cycle a decade ago, and Palo Alto Networks, CrowdStrike, and Wiz built multi-billion-dollar businesses on the gaps native cloud controls left open. Agent security is tracking the same path faster. A misconfigured storage bucket sat open until a human noticed. A misconfigured agent exploits its own over-permissioning on every run, and no human is watching when it does. Merritt Baer, chief security officer at that the default layer is thinner than enterprises assume. "Enterprises believe they've 'approved' AI vendors, but what they've actually approved is an interface, not the underlying system," Baer said. "The real dependencies are one or two layers deeper, and those are the ones that fail under stress."
Comfortable, unconvinced, and already shopping
Here is the contradiction worth a keynote slide. Enterprises rate their agent security tooling 4.2 out of 5, with value for money at 4.1 and ease of implementation at 3.9. Those scores would make most SaaS vendors envious.
Only 35% believe their AI-enabled defenses are ahead of AI-enabled attackers, while thirty-two percent call it roughly even. Twenty-one percent say attackers lead, and another 21% say it is too early to tell, showing how enterprises trust their tooling more than they trust its outcomes.
Budgets confirm it. Forty-six percent allocate 6 to 10% of the security budget to agent security, and a full third spend 5% or less. Half the sample has already had an incident or near-miss, but the funding does not match the exposure.
Fifty-nine percent plan to adopt, add, or replace agent security tooling within 12 months, and twenty-nine percent plan to move this quarter. OpenAI leads forward interest at 34%, followed by Google at 30%, Anthropic at 29%, and Azure at 25%. The dedicated vendors draw more interest looking forward than their current single-digit footprint suggests. Satisfied customers do not reshuffle this fast unless they know the stack they're currently using is provisional.
Three moves for security directors
1. Inventory every agent’s credentials this quarter. Map which agents share credentials with other agents and which run on borrowed human or service-account identities. The goal is not one credential per agent. Agents that touch multiple systems need multiple scoped identities. The goal is zero shared credentials between agents and zero borrowed human identities. Thirteen percent of surveyed enterprises already run Microsoft Entra Agent ID. Okta for AI Agents and the non-human identity specialists sell equivalents. Shared and borrowed credentials are the first thing to eliminate.
2. Sandbox the riskiest agents first. Isolation is the least-adopted control at 30% and the only one that contains blast radius after prevention fails. Rank agents by the sensitivity of what they touch and isolate the top of the list. Above 1,000 employees, where isolation falls to 20%, this is the single highest-return move in the dataset. Sandboxing does not require replacing the agent or the platform. It requires a policy decision and an isolation layer.
3. Match the budget to the incident rate. A third of enterprises fund agent security at 5% or less of the security budget, even though more than half have already had an incident or near-miss. Nine percent allocate more than 25% today. The full report breaks out exposure and containment by company size, showing which bands carry the most risk and the least protection.
The board's question is simpler. If one of our AI agents was compromised this afternoon, which systems did it touch, and whose credentials was it holding? For the 69% of enterprises running agents on shared credentials, the answer is a shrug. The trail goes cold at the key.
The full Q2 Agentic Security report, with the complete vendor matrix, industry cuts, and the full dataset behind these charts, debuts July 14 and 15 at VB Transform, held at Hotel Nia in Menlo Park. The open question it leaves is whether enterprises close the agent security gap on their own terms, or whether a confirmed breach closes it for them.
