Custom agent harnesses
Define how agents plan, use tools, retain context and handle errors. Set completion conditions and escalation paths around the work the agent is there to do.
The outputA harness tailored to a specific operational task.
Agentic Workflows
Turn a defined task
into a working system.
Connect models to the tools and context they need to do useful work. We build custom agent harnesses, integrations and approval steps for security and investigation teams.

01 / The objective
Build the system
around the model.
Operational work spans tools, data sources and teams. Connecting a model is one step; the surrounding system determines which actions it can take, what context it receives and when a person needs to decide.
We build that system around a defined task. Harnesses manage tool use and context, integrations connect the environment, and permission boundaries keep actions within the workflow you approve.
- A task with clear boundaries
- Define a useful outcome, available tools and conditions for completion.
- Integrations that carry the work
- Connect the data and APIs needed across the workflow.
- Actions your team can review
- Keep permissions, approval points and an audit trail explicit.
02 / Capabilities
The pieces that make
an agent operational.
Tool and data integrations
Connect the APIs, security tools and data sources your team already uses. Shape tool access around the information and actions each workflow requires.
The outputScoped integrations across the systems involved in the task.
Human control and permissions
Set boundaries on data access and tool use. Add approval points where your team needs to review a decision before the workflow continues.
The outputExplicit permissions, review steps and handoffs.
Evaluation and audit trails
Review behaviour against representative tasks, including errors and incomplete evidence. Keep a record of tool calls, decisions and actions to support operational review.
The outputEvidence for assessing the workflow and understanding what happened.
03 / In practice
Start with work
that has a clear outcome.
Investigation preparation
Gather information across tools and assemble evidence for a person to review.
Security workflow automation
Connect enrichment, case preparation and approved actions in a defined sequence.
Work across tools and teams
Carry context between systems and make handoffs and approvals part of the workflow.
04 / How we work
An objective. A working process.
A result you can review.
- 01 /
Choose the task
Define the outcome, tools, data access and points where people need to decide.
- 02 /
Build and evaluate
Implement the harness and integrations, then review behaviour against representative work.
- 03 /
Operate and refine
Introduce the workflow with agreed permissions, review its actions and refine it with your team.
