Ultra Security, a US-based cybersecurity startup developing runtime protection for autonomous AI agents, announced $10 million in seed funding on October 21, 2026, alongside its emergence from stealth.
The funding round included participation from Ludlow Ventures, Hidden Capital, Entrée Capital, Detroit Venture Partners, firedrop, and FDVC. Angel investors from the cybersecurity and software industries also participated, including Shrav Mehta, Tim Sadler, and Christina Cacioppo.
Founded in 2025 by Chase Lee and headquartered in Birmingham, Michigan, Ultra Security develops software that helps organizations monitor and control how AI agents interact with applications, tools, and sensitive information.
Lee previously founded and served as CEO of Trustpage, a security and compliance company acquired by Vanta in 2023. He subsequently worked at Vanta in a product leadership role before establishing Ultra Security.
Ultra Security’s platform operates between autonomous AI agents and the external systems they access, including Model Context Protocol (MCP) servers and connectors. It enables organizations to inspect agent activity, enforce security policies, and manage access permissions as actions occur.
The platform combines security guardrails, governance, observability, runtime protection, and alerting. Its capabilities include monitoring tool requests, restricting unauthorized data access, identifying unusual activity, and maintaining audit records of agent interactions.
Ultra Security offers a local-first deployment model that keeps activity records and related data on the user’s machine by default. A remotely hosted deployment option is also available.
The company developed its platform while operating in stealth and working with customers and design partners. Following its public launch, organizations can request access to the platform through Ultra Security’s website.
