Zenity is a well-known platform for securing AI agents, with coverage for agent discovery, posture management, real-time detection and inline prevention. If you are evaluating alternatives, the right choice depends on where you need enforcement, which agent platforms you run, and how much your security team wants to manage. This page lays out what to compare.
Why teams look beyond a single vendor
- They run agents across several frameworks and want one control plane across all of them
- They need enforcement at the tool-call and MCP layer, not only detection and posture
- They want policy tied to data access, so an agent can only use data for an approved purpose
- They need audit evidence mapped to regulatory frameworks
Zenity alternatives at a glance
- Trust3 AI: agent discovery, observability and purpose-based enforcement across agents and the data they reach, with MCP servers untrusted by default
- Noma Security: agentic AI security covering AI supply chain security and real-time monitoring
- Palo Alto Networks Prisma AIRS: network and gateway-centric AI runtime protection, strongest for existing Palo Alto customers
- Fiddler: AI observability focused on model and agent behavior, quality and drift
- Data governance suites such as Securiti, OneTrust and IBM: privacy and data controls extended to AI
What to compare
- Agent platforms covered and how discovery works
- Where policy is enforced: at the network, in the agent runtime, or at the data
- Depth of MCP and agent-to-agent controls
- Evidence and audit reporting
- Deployment effort and operating model
Where Trust3 AI fits
Trust3 AI is the security control plane for enterprise AI agents and the data they reach, built by the creators of Apache Ranger. It helps teams discover every agent, observe every decision, and secure every action, enforcing purpose-based access controls at the moment an agent calls a tool or reads data. MCP servers are treated as untrusted by default, and agent-to-agent delegation is governed at each hop.

Frequently asked questions
What are the best Zenity alternatives for AI agent security?
Common alternatives include Trust3 AI, Noma Security, Palo Alto Networks Prisma AIRS, and data governance suites that extend into AI. The best fit depends on whether you need agent-native enforcement, network-layer protection, or data-centric controls.
How does Trust3 AI differ from Zenity?
Trust3 AI emphasizes purpose-based enforcement at the moment an agent calls a tool or reads data, vendor-neutral coverage across agent platforms, and governance of MCP and agent-to-agent traffic. See the direct comparison page for detail.
Can I use Trust3 AI alongside another agent security tool?
Yes. Many teams layer an agent-native control plane with perimeter or observability tools, since they address different enforcement points.
