Palo Alto Networks, a cybersecurity solutions company, said it plans to acquire Portkey, a company known for building AI Gateway technology designed to manage and secure autonomous artificial intelligence (AI) agents.
Through the deal, Palo Alto Networks is strengthening its efforts into enterprise AI security as more companies deploy AI copilots and autonomous AI agents that can make decisions, access systems, and automate workflows with minimal human input.
Portkey’s platform already processes trillions of AI tokens every month and is designed to handle low-latency communication between AI agents. Palo Alto Networks said the technology will become part of Prisma AIRS, its AI security platform, giving companies centralized visibility and control over AI traffic across their organizations.
“As autonomous agents join the enterprise workforce, they also become a new, unmanaged attack surface,” Lee Klarich, chief product and technology officer of Palo Alto Networks, said in a statement. “By integrating Portkey into Prisma AIRS, organizations will be able to confidently deploy and govern AI agents. With Portkey, we are providing enterprises with visibility into all their agentic traffic, and enabling them to control and protect against agentic threats.”
The company said AI agents are creating new cybersecurity risks because they operate like highly privileged insiders capable of accessing internal and external systems automatically. As adoption grows, businesses need tools that can monitor AI behavior, enforce security policies, and prevent data leaks or unauthorized actions.
Following the acquisition, Portkey will serve as the AI Gateway for Prisma AIRS, helping organizations inspect AI traffic, apply governance policies, and secure AI workloads in real time.
Palo Alto Networks said the combined platform is designed to deliver 99.99% uptime for autonomous AI workloads through automated failovers and semantic routing. It will also provide telemetry, audit logs, centralized management, and access controls across more than 3,000 large language models (LLMs) and MCP tools.
“Scaling AI in production requires a delicate balance between total flexibility for developers and absolute control for security teams,” Rohit Agarwal, CEO and co-founder of Portkey, said. “By joining Palo Alto Networks, we will establish the AI Gateway as the foundational layer of the secure AI enterprise. Together, we will provide the infrastructure that allows every organization to deploy autonomous agents with the confidence that their data and operations are fully protected.”
Palo Alto Networks said it will continue supporting existing and new Portkey customers after the transaction closes. The acquisition is expected to close during Palo Alto Networks’ fourth quarter of fiscal 2026, subject to customary closing conditions.
