Most writing about red teaming is aimed at the people who run it. Very little is aimed at the people who approve it, pay for it and have to act on the result. That is an odd gap, because the decisions that determine whether a red team engagement is worth the money are nearly all made at executive level: what it is for, what it is allowed to touch, who gets told, and what happens afterwards.
This is written for that audience. It assumes you are not going to read the technical appendix.
What a Red Team Exercise Actually Proves
A penetration test answers a question about systems: where are the exploitable weaknesses in this environment. A red team exercise answers a question about your organisation: if a capable attacker set out to reach something that matters, would anyone notice, and could they be stopped.
That distinction matters at board level because the two produce different evidence. A penetration test gives you a list of issues to fix. A red team exercise gives you an honest measurement of three things you otherwise have to take on faith:
Whether your detection works against a real adversary rather than against a test case someone wrote for it. Most organisations have invested heavily in monitoring. Very few know what it actually catches.
How far someone gets once they are inside. Prevention eventually fails, usually through a person rather than a system. The question that determines the size of the incident is what the intruder reaches in the hours that follow.
Whether your people and processes hold under pressure. Not whether a policy exists, but whether the on-call engineer at 2am escalated, and how long the chain took.
A red team exercise does not prove you are secure. Nothing does. It proves what a specific adversary, pursuing a specific objective, could achieve against you on a specific set of days.
What Leadership Should Receive
If the only thing you get is a technical report, the engagement has been delivered badly. Leadership should receive four things.
An executive narrative that reads as a story. How the operators got in, what they did next, where they ended up and what it would have cost you. Written in plain language, with no requirement to understand the tooling. If your executive team cannot follow it without a translator, ask for it to be rewritten.
A timeline against your detection. The single most valuable artefact in the report. It sets out what the operators did and when, alongside what your security function saw, when it was flagged, and when it was escalated. The gaps in that timeline are the finding. This is also the piece most often missing, so ask for it explicitly during scoping rather than afterwards.
Demonstrated impact, not theoretical risk. "Domain administrator was obtained" means little to a board. "Payroll, the customer database and the backup environment were all reachable from a single compromised laptop" means a great deal. Insist that findings are expressed as business consequence.
A prioritised remediation path with owners and effort. Ordered by what reduces the most risk, not by severity score. A list of forty items with no sequencing is a way of making the problem someone else's.
The Questions Worth Asking
When the report lands, these are the questions that separate a useful exercise from an expensive one.
What did we detect, and how long did it take? If the answer is that nothing was detected, that is a finding about your monitoring investment, not a failure of the exercise.
What did you not try, and why? Good operators work within rules of engagement. Knowing what was off limits tells you how much of your real exposure was actually tested, and what remains unknown.
If you had another two weeks, what would you have gone after next? This question routinely produces the most valuable paragraph in the whole engagement, and it is almost never in the written report.
Which of these findings would have been caught by something we already own? Frequently the answer is most of them, and the problem is configuration or tuning rather than a missing product. That reframes the remediation budget conversation entirely.
What would you fix first if this were your business? Ask the operator, not the account manager.
What It Should Cost, and What Drives That
Red team engagements are substantially more expensive than penetration tests, because they take longer and require more senior people. The cost is driven by the duration of the exercise, the number of objectives, whether physical and social engineering are in scope, and how much stealth is required. A quiet engagement designed to avoid detection takes considerably longer than a loud one.
The most common way to waste money is to buy a red team exercise when the organisation is not ready for one. If you already know your monitoring has significant gaps, or you have never run a penetration test, a red team exercise will tell you what you already suspect at several times the price. Fix the known problems first, then measure what remains.
Scoping Decisions Only Executives Can Make
Three decisions cannot be delegated.
Who knows. If the security team knows the exercise is running, you measure their best case. If they do not, you measure reality, but you accept the risk of a genuine incident response being triggered. Most organisations run the first exercise informed and later ones blind. Either is defensible; drifting into one without deciding is not.
What the objective is. "Test our security" is not an objective. "Reach the customer database", "obtain a payment approval", "exfiltrate the board pack" are objectives. They should be the things that would genuinely hurt, chosen by people who know what the business cannot afford to lose.
What is off limits. Production systems that cannot tolerate disruption, safety-related environments, and anything under a change freeze. This protects the business, and it has to be an executive decision because only executives can weigh the operational risk against the value of the knowledge.
Afterwards
The engagement is not finished when the report arrives. The organisations that get value from red teaming do two things consistently.
They run a purple team session: the operators walk the defenders through exactly what they did, step by step, while the defenders check what their tooling recorded. Detection improves more in that one session than in the preceding month of remediation.
And they retest. A finding that was reported, accepted and never verified as fixed is not remediation, it is documentation. For entities with obligations under APRA CPS 234 or the SOCI Act, that verification is also what turns the exercise into evidence you can put in front of a regulator.
Where to Start
If you are approving your first engagement, the honest sequence is: a penetration test to find and fix the known weaknesses, then a red team engagement to measure what an adversary could still achieve, then adversary simulation on a regular cadence to keep detection sharp.
