So You Need an Agent Harness...
Spinning up an AI agent is the easy part. Getting it to hold up in a real-world environment is the real challenge. This guide walks through what it takes to build the orchestration layer, meaning the software system that decides which agent does what, in what order, and how results get checked, based on Synack's own experience building Sara, the Synack Autonomous Red Agent.
Top 3 Requirements
For a reliable harness, spanning architecture, operations and maintenance.
5 Build Phases
From discovery through consolidated reporting, mapped out from how Sara was actually built.
Hundreds of Agents
Per job, with count scaling automatically based on target size.
Built from Scratch
Synack tried several off-the-shelf multi-agent frameworks before building the layer themselves.

Get the full walkthrough of the orchestration layer behind Sara, including the five build phases, the architectural tradeoffs Synack made, and why an off-the-shelf framework wasn't enough.
No form required.
Will You Build or Buy?
Getting the orchestration layer right takes real trial and error, ongoing investment to keep pace with new models, and constant validation to confirm performance holds up outside a lab setting.
