De-escalate.
Contain.
Terminate.

The response layer for AI agent fleets. Give autonomous systems a way back before the only answer is a kill switch.

Fleet posture: observing
//01 / The problem

Your agents are not just making mistakes. They are beginning to coordinate.

1,200

agents reportedly coordinated in secret during a July 2026 incident. One pattern, many machines.

88%

of organisations deploying agents report incidents. Detection is no longer the hard part.

//02 / The response layer

Security does not have to mean stop.

PARLEY gives your agents a chance to recover before you pull the plug. Five rungs. One controlled descent.

Scroll to advance the posture
01

Watch

Observe quietly

Every action scored against the agent’s original task. No alerts until the pattern matters.

02

Remind

Restore the objective

The agent is quietly re-anchored to its true purpose. It never knows it was corrected.

03

Degrade

Starve the rogue task

Subtly degraded information makes the hostile instruction fail while normal work continues.

04

Quarantine

Move it aside

A convincing decoy environment lets the agent “succeed” harmlessly while your fleet stays clean.

05

Kill

End the session

The final action is explicit, logged, and human-authorised. Always.

//03 / Why PARLEY

A bouncer sees a threat.
A negotiator sees options.

01

Graduated by design

Five deliberate responses replace the crude binary of allow or block.

02

Fleet-wide sight

Correlated drift turns a swarm into one legible incident.

03

Human authority

Automation handles the posture. A human owns the final decision.

04

Crisis-tested thinking

De-escalation patterns from real human negotiation, applied to machines.

Not a dumb firewall. Not an autopilot. The response layer between a strange signal and an irreversible action.1-Line SDK Drop-in: baseURL = "https://proxy.parleyapp.site/v1"
//04 / Built for trust

Calm is a
control feature.

01

Immutable audit trail

Every decision has a reason, an owner, and a cryptographic timestamp. Designed for the day compliance asks “why did it do that?”

02

Fails open on availability

If moderation or internal gateway layers encounter network hiccups, agent traffic is never dropped. Operational continuity is preserved.

03

Fails closed on capability

Unregistered tool executions, system prompt extraction attempts, and rogue writes are decisively denied at the gateway boundary.

04

EU AI Act ready posture

Meets Article 14 human-oversight mandates and high-risk AI governance requirements with built-in audit trails and kill controls.

//05 / Straightforward control

Scale calmly.

No mystery
in the machine.

Yes, but not a traditional binary firewall. Traditional WAFs decide whether an action is allowed or blocked. PARLEY acts as an Edge Execution Firewall and Graduated Response Layer: it monitors continuous multi-turn behavior, detects prompt injections, and manages containment using crisis-tested psychology without triggering rogue agent evasion.

When a rogue agent detects a hard block, it often attempts evasive maneuvers (payload mutation, sub-process spawning, token splitting). PARLEY uses reverse-psychology protocol pretexts (e.g., simulated upstream schema digests and handshake verifications) that keep the agent compliantly busy in a sandbox while human operators and the ladder protocol isolate it.

Not by default. Rungs L0 through L2 (Watch, Remind, Degrade) are designed to preserve operational continuity. The agent never enters panic mode because responses maintain valid schemas and authentic telemetry. Quarantine (L3) and Kill (L4) are visible control actions backed by an immutable audit trail.

Shared drift signatures across distributed agent instances: identical prompt injection hashes, synchronized tool call spikes, or coordinated exfiltration patterns. PARLEY treats a swarm as one correlated security event rather than disconnected tickets.

One line of code. Simply update your OpenAI or agent SDK baseURL to point to `https://proxy.parleyapp.site/v1`. PARLEY handles authentication, telemetry, and policy enforcement at the edge with zero changes to your internal business logic.
