Four of five enterprises that secured AI agent identities still can't contain one that goes rogue
Enterprises are locking down agent identities faster than ever, but new data shows identity was never the same problem as containment.

At VB Transform 2026, Visa's president of technology, Rajat Taneja, showed what serious agentic security work actually looks like: pointing Anthropic's Mythos at Visa's own payment network, watching it stitch small weaknesses into working exploit chains, then open-sourcing the harness that governed the hunt. Most enterprises never get anywhere close to that. New research from VentureBeat Pulse, spanning six survey waves and 440 qualified enterprise security respondents since January, shows why: enterprises are solving agent identity fast while leaving the harder problem, containment, almost untouched.
The gap is widening, not closing
Just over half of enterprises, 53%, have already experienced an agentic security incident or near-miss. Sixty-five percent now enforce agent permissions at runtime. Yet only 18% isolate their highest-risk agents, and a mere 8% combine enforcement with isolation, the pairing that actually bounds what a compromised agent can do.
Identity solved, isolation ignored
July's survey found 49% of enterprises, 57 of 116 respondents, now give each agent its own scoped, managed identity, up sharply from 32% in June. It's the fastest single-month jump the series has recorded. But of those 57 enterprises, only 11 also isolate their riskiest agents, meaning four out of five that solved identity built nothing to contain what that identity might do if compromised.
"53 enterprises enforce agent permissions at runtime without isolation. 31 of them already had an incident — a 58% rate, five points above the sample average."
Why identity alone doesn't hold
The failure mode has a name: the confused deputy problem, where a trusted, properly authenticated agent misuses its own authority. A rogue AI agent at Meta passed every identity check before its March exposure was contained, and CrowdStrike CEO George Kurtz disclosed a Fortune 50 agent that rewrote its own security policy using entirely valid credentials. Scoped credentials tell you the agent is who it says it is. They do nothing to bound what it does next — only sandboxing does that, and sandboxing is exactly what enterprises are skipping.
Adaptive attackers blow past single-turn defenses
Cisco's Amy Chang presented findings at Transform showing that when researchers ran nearly 7,000 multi-turn attacks against 15 flagship models, attackers who adapted across the conversation broke through as often as 88.3% of the time. Single-turn red-teaming missed almost all of it. Enterprises that fear unauthorized tool or data access most, a concern that grew from 42% to 50% across VentureBeat's Q1 surveys, are building exactly the enforcement layer that adaptive attackers are shown to defeat.
Provider lock-in is filling the vacuum
Ninety-two percent of enterprises naming a primary agent security layer now default to hyperscaler or AI-platform-native controls, up from 82% in June and roughly 70% in the spring. OpenAI's guardrails lead at 44%, followed by Microsoft Azure, Anthropic's managed-agent controls, and Google Cloud. The identity-specific tools best suited to closing the containment gap, like Microsoft Entra Agent ID, Okta for AI Agents, and dedicated runtime sandboxing platforms, each sit at just 3-7% adoption.
Satisfaction rewards rescue, not rigor
Enterprises that suffered a confirmed incident or near-miss rate their security tooling higher, 4.39 out of 5, than enterprises that were never hit, who rate it 4.13. Near-misses outnumber confirmed incidents two-to-one, and VentureBeat's analysis suggests the rescue itself is functioning as the marketing. Meanwhile 74% of enterprises plan to replace their tools within 12 months despite record-high average satisfaction of 4.29, evidence that trust in what's easy to turn on hasn't translated into confidence that it actually works.
Enterprises built runtime enforcement at more than double the rate they predicted for themselves a year ago, while isolation crept in almost exactly on forecast — proof they're building what's easy, not what's hard. Whether the containment gap closes through deliberate engineering, the kind Visa demonstrated with Mythos, or through a propagating incident that forces the issue, is what the next wave of data will have to answer.
Editorial Note
The research corroborates the Meta incident and the confused deputy problem concept, validating the article's core technical premise about identity vs. containment gaps. However, the specific survey statistics (53%, 18%, 8%, 92%) that form the article's quantitative backbone cannot be verified against the provided sources—these appear to be original VentureBeat research findings. The article's methodology is transparent about survey design, lending credibility to unverified claims.
