The trust layer for
autonomous AI agents.

NIANSYS observes what your AI agents do, not just what they say. Detect behavioral deviations, block unsafe actions, and keep a full audit trail — in real time.

Why now

AI agents are deploying faster than oversight.

2026 is the year autonomous agents enter production. Most teams are shipping without a safety net.

0%

of enterprises plan to deploy autonomous AI agents in production workflows by end of 2026.

$0M

average cost of a data breach in 2025, with AI-driven incidents now in the top 3 attack vectors.

<0%

of teams running AI agents have a real-time monitoring solution for what those agents actually do.

The trust gap

Your agents are taking real actions.
You can't see them.

The capabilities of AI agents are evolving faster than the tools to watch over them. That's the gap NIANSYS closes.

01
👁

Invisible actions

Agents send emails, run code, hit your APIs, move money — and your dashboards have no idea any of it is happening.

02
📡

No risk signal

Existing observability tools (Langfuse, Helicone, LangSmith) watch what agents say. Almost nothing watches what they do.

03

No way to stop it

When an agent goes off-rails, you find out from a customer complaint or a bank notification — never from your monitoring.

What NIANSYS does

One SDK. Three layers of protection.

NIANSYS sits between your agent and the systems it touches. Every action passes through — scored, classified, and (optionally) blocked.

Observe

Every action, in real time.

Each tool call, API request, or file write is captured and persisted with full context. Searchable timeline, agent-by-agent breakdown.

Understand

Learn what's normal for this agent.

The Risk Brain builds a behavioral baseline per agent (frequency, action types, time windows). Statistical deviations are flagged automatically.

Protect

Block what shouldn't pass.

Define policies per agent: action types, score thresholds, keywords, amount limits. Risky calls are denied at the source, with full audit trail.

See it in action

A dashboard built for the people in the loop.

Per-agent baselines, behavioral deviations, full event timeline. Everything you need to understand and trust your agents.

Async also supported — await guardian.acheck(...)
