This guide examines the 15 best solutions for securing AI agents in 2026, spanning enterprise MCP gateways and dedicated security platforms. These are: preventing agent sprawl and access to resources, protecting against data oversharing and data leaks, defending against new AI threats and vulnerabilities, and adhering to evolving regulations. Addressing these challenges holistically requires a coordinated effort across IT, developers. On-device AI refers to the use of AI models and algorithms directly on a device (like smartphones, cameras, or wearables) rather than relying on cloud-based processing. This shift toward edge computing enables real-time, efficient, and privacy-conscious operations, transforming industries from. Ready to secure your agentic AI workforce? Cisco defends against agentic AI security risks by uniquely tying identity context directly to access control and real-time behavior. Discover and. MCP is an open standard that allows AI agents to securely and effectively connect with external data sources, tools, and services—providing flexibility to fetch real-time data, call external tools, and operate autonomously. This open standard essentially acts as a “USB-C port for AI. Uncover all MCP servers everywhere they run to gain full visibility and a clear, guided path to governing your entire MCP footprint.
