Agent Security Posture
Inventory the agents and MCP servers in production, map the tools each can call, and catch the multi-step chains where an agent is steered into misusing its own authority.
Last reviewed July 2026
The gap Agent security closes
An agent with tool access is a confused deputy waiting to happen: untrusted content in a document or a tool result can steer it into reading a secret and sending it out, or changing a config and planting persistence. Single-step filters miss the chain.
How Penaxtra delivers Agent security
Penaxtra registers agents and MCP servers as typed assets, inventories the tool catalogue each exposes, and watches sequences of tool calls with subsequence matching and gap tolerance. Escalation chains - credential read to network send, generated script to execute, config change to persistence, hidden recipient to email send - raise findings mapped to the OWASP Agentic Top 10.
