AI Agents That Do What They’re Told

As AI agents gain autonomy for calling tools, executing workflows, and interacting with users, governing what they do matters as much as what they say.

Gray Swan keeps your agents in line without slowing them down.

Autonomy without governance is just risk you haven’t measured yet.

Enterprises are deploying AI agents that don't just answer questions; they act. They book meetings, pull records, trigger workflows, and interact with customers autonomously. The problem isn’t that agents make mistakes. It’s that no one finds out until the damage is done.

Scope creep

Agents exceed their intended boundaries, taking actions they were never designed to take.

Inconsistent behavior

The same agent behaves differently across users, contexts, or edge cases with no accountability trail.

Ungoverned tool use

Agents call APIs, databases, and third-party services without validation of whether they should.

Compliance blind spots

Regulated industries need provable controls over AI decision-making, not just output filtering.

You wouldn’t give a new employee admin access to every system on day one.
Your agents shouldn’t have it either.

Built to Hold. Proven Under Pressure

Every attack we run sharpens what we stop. Every attack we stop is one we've already run.

RUNTIME DEFENSE

Define the rules. Enforce them in real time.

Enforce behavioral policies on every action an agent takes: tool-calls, response generation, data access, multi-step workflows. You define what's in-bounds. Cygnal ensures your agents stay there, even when they encounter novel inputs or adversarial manipulation.

ADVERSARIAL RED-TEAMING

Break your own governance before attackers do.

Shade simulates the edge cases, adversarial prompts, and unexpected inputs that push agents outside their intended behavior, so you know your guardrails work before production, not after an incident.

What this looks like in practice

CygnaL
Behavioral Policy Enforcement

Define what actions your agents can and can't take — by role, context, or workflow. Cygnal enforces it at runtime across every interaction.

Shade
Agent Red-Teaming

Systematically tests whether agents can be manipulated into unauthorized actions, policy violations, or out-of-scope behavior before you deploy.
