The decision this guide helps you make
The control team needs the authority and contacts to act during the test, not just a place in the project chart. Agree who can stop activity, how to distinguish exercise events from real incidents and how decisions will be recorded without exposing the exercise unnecessarily.
For the engagement owner. The control team needs clear authority, dependable contacts and an operating record. Rehearse the stop and escalation decisions before technical activity begins.
The control team connects realism with accountability
The control team is the restricted group inside the financial entity that knows about and manages the test. It coordinates the exercise while preserving the conditions needed to assess the defenders’ capabilities. Its lead is a central point of contact for providers and the authority’s test managers.
A control team should not be a name added to a project plan after procurement. Its membership, authority, confidentiality and escalation arrangements shape whether testing can proceed safely and produce useful evidence.

Before testing: make decisions executable
- Confirm who can approve activity, change a boundary or stop the test.
- Establish secure communication and a need-to-know approach.
- Connect critical-function owners, operational constraints and provider dependencies.
- Agree rules of engagement, incident handling and emergency contacts.
- Plan which documents require review and how authority coordination works.
These decisions should be documented in a way that participants can actually use under time pressure. Ambiguous ownership becomes most costly when an unexpected production issue arises.

During testing: distinguish the exercise from a real incident
Controlled testing does not remove the possibility of a genuine attack or unrelated service disruption. The control team needs a process for distinguishing events, escalating uncertainty and pausing activity when warranted.
Keep records of material decisions, assumptions, restrictions and changes. The purpose is not to create paperwork for its own sake, but to preserve why an action was authorised and how risk was assessed. Avoid exposing the exercise unnecessarily to the broader defensive team.

At closure: turn observations into learning
The red team’s record and the blue team’s experience may tell different parts of the same story. The control team helps reconcile them through the applicable reporting, replay and purple-team process.
For example, an action may have generated telemetry without triggering an investigation, or a detection may have led to a response that did not contain the scenario. These are distinct outcomes and call for different improvements. A single vulnerability list would miss that distinction.

Keep ownership beyond the final meeting
Closure should produce agreed remediation actions, accountable owners and a process for tracking completion. The financial entity remains responsible for its regulatory obligations and follow-through even where a provider supports documentation.
Plan the handover from the restricted testing group to the teams that will implement improvements. Information should reach the people who need it while sensitive attack details remain appropriately controlled.
Rehearse a realistic coordination problem
Consider an unexpected service symptom during an authorised activity. The control team needs to identify the affected owner, understand the current test action and reach the people able to pause it. Agree what acknowledgement is required and how a resumption decision is recorded. Also rehearse an unrelated real incident during the exercise. The coordination model should help the organisation investigate it properly without assuming that every suspicious event belongs to the test.
Technical entry routes complicate these decisions. The bank privileged access guide helps distinguish the identity, network and application owners who may need to explain a particular observation. Keep the restricted contact map consistent with the actual scope.
Maintain a concise decision log
Record material approvals, pauses, assistance, changes and unresolved questions with their rationale and responsible participants. The log should make it possible to reconcile what happened without becoming a repository for unnecessary sensitive data. Use the agreed confidential channel and access restrictions. When the exercise moves into closure, this record helps distinguish observed control behaviour from outcomes affected by assistance or operating constraints.
For release-dependent systems, the fintech evidence and retest guide explains why version context belongs alongside an observation. The control team should be able to identify relevant changes during the exercise and bring them into the appropriate review process. Clear coordination supports useful learning because later readers can understand the conditions under which each result was obtained.
