AI Agents Are Creating a New Identity Security Problem
AI agents are proliferating across enterprises faster than security teams can track them, creating an identity-management challenge that many organizations are unprepared to handle, Entrust CIO Rishi Kaushal told Information Security Media Group. Unlike human users, autonomous agents spin up their own machine identities and act with delegated privileges, expanding the attack surface as agent sprawl outpaces existing governance. Kaushal argues that agent governance, visibility and lifecycle management must become core components of enterprise security, extending zero-trust principles to non-human actors. The interview, published July 3, frames identity as the control plane for securing agentic AI, a concern increasingly relevant to healthcare’s data-rich environments.

Why CIOs Need an AI Sovereignty Strategy
Most enterprises are far more dependent on their artificial-intelligence vendors than leaders realize, and a new IBM study attaches a dollar figure to that exposure, according to a July 2 analysis published by Information Security Media Group. The report urges chief information officers to build an AI sovereignty strategy that reduces vendor lock-in and preserves control over models, data and infrastructure before market conditions force a costly reckoning. Recommended measures include hybrid-cloud deployment and clearer governance over where AI workloads run. For healthcare CIOs weighing rapid adoption of clinical and administrative AI tools, the guidance underscores the operational and financial risks of over-reliance on a single provider.

FDA Grants Aurenar Breakthrough Status for Brain-Bleed Device
Aurenar received FDA Breakthrough Device designation for its V-Link System, a wearable intended to reduce cerebral vasospasm in adults who have suffered an aneurysmal subarachnoid hemorrhage, MobiHealthNews reported July 1. The designation covers patients 22 and older as an adjunct to ICU management. V-Link delivers low-energy electrical stimulation to a branch of the vagus nerve through the outer ear, aiming to regulate the inflammatory response that can drive secondary brain injury after hemorrhagic stroke. Founder and CEO Dr. Eric Leuthardt, a neurosurgery professor at Washington University School of Medicine in St. Louis, said standard vasospasm care, chiefly oral nimodipine and hemodynamic support, has changed little in decades.

The Elephants in the Technology Room – Part 4
Shadow IT has evolved well beyond rogue laptops into shadow SaaS, shadow AI, shadow data and autonomous agents that operate outside security teams’ field of view, argues Krishna Bagla in the fourth installment of his Elephants in the Technology Room series, published July 3 by Information Security Media Group. Traditional governance models built on blocking unapproved tools can no longer keep pace with how employees adopt cloud applications and generative AI, Bagla writes. He calls on organizations to shift from prohibition toward making technology use visible, monitored and data-controlled. The essay is directly relevant to healthcare providers, where unsanctioned SaaS and AI can expose protected patient data.
