Treat library size as a starting point. Score whether the scenarios map to ATT&CK, match your controls, and can be retested after a fix. A smaller pack you run every week beats a catalogue nobody schedules.
Buyer’s Guide
How to Choose a Breach and Attack Simulation Platform
A buyer’s guide to breach and attack simulation platforms: scenario quality, production safety, ATT&CK depth, control coverage, integrations, remediation, and the team capacity to act on gaps.
Choose for the Programme You Can Run
The shortlist should start from your controls, not a feature matrix.
Choosing a BAS platform means…
Testing whether a product can safely exercise the controls you already own, record a technique-level result, hand a miss to the person who can fix it, and retest — with a team that has time to do the fixing.
Public comparisons of the category converge on the same themes: library freshness, MITRE ATT&CK depth, multi-vector coverage, purple-team workflow, deployment model, and whether detection engineering can absorb the findings. Those themes are the right scorecard.
A platform that finds more gaps than your team can close will sit idle after the first quarter. Capacity to remediate is part of the buying decision.
Start from the stack
List the EDR, email gateway, firewall, and SIEM you must prove. A platform that cannot reach one of them is a partial answer.
Ask for a retest
In the pilot, change one detection and run the same scenario again. The before-and-after record is the buying evidence.
Name an owner
If nobody owns the weekly pack and the ticket queue, the licence will outlast the programme.
Evaluation Criteria
What to score in the pilot.
Score these on your environment. A scripted demo tenant hides scope, identity, and logging problems you will meet in production.
Production safety
Inert execution, explicit scope, exclusion lists, and a stop control. Ask what the simulation refuses to do, not only what it can emulate.
Library and freshness
ATT&CK-mapped scenarios you can update when a technique starts mattering to your sector. A large library you cannot prioritise is noise.
Control coverage
Endpoint, email, network, and SIEM in one result model. Coverage of a single vector leaves the rest of the kill chain unmeasured.
Detection proof
The platform should show whether the SIEM raised a usable alert, not only whether an endpoint agent flashed green.
Remediation path
A miss needs an owner, a recommended change your control can accept, and a retest of that exact scenario.
Reporting by audience
Technique detail for detection engineering. Trend, drift, and residual gap for the CISO. The same data, two views.
Pilot Questions
Ask these before you sign. Weak answers are easy to spot.
| Ask | A strong answer | A weak answer |
|---|---|---|
| Where will test points run? | Named host groups inside change control | “Anywhere the agent installs” |
| How is a miss closed? | Same scenario ID, retest, stored delta | A new report next quarter |
| Can you target our SIEM? | Expected log source and detection name | A generic alert-volume chart |
| Who updates content? | A dated feed tied to techniques you track | A static pack from onboarding |
| What can it not test? | A clear boundary versus pentest and scanning | “It replaces red team” |
| What does week six look like? | A named operator and a ticket queue | “The customer success manager will run it” |
Readiness
Buy when the prerequisites exist.
The category exists because deployed controls drift. It pays off when someone can change those controls after a miss.
Ready to pilot
- EDR, email, network, or SIEM already in production
- A detection engineer or control owner with weekly time
- Change control that can approve inert simulations
- A ticket path from finding to rule change
- An executive who wants a trend, not a one-off score
Pause the purchase
- No one can edit detection content or gateway policy
- Scope cannot be agreed with IT operations
- Success is defined as “a dashboard” with no remediation
- The team expects the platform to discover novel exploits
- Logging is too incomplete for a detection result to mean anything
Frequently Asked QuestionsPlatform selection,
Platform selection,
answered.
Yes, if you need to know whether known techniques still fail between engagements. Penetration testing remains the way to find paths a library will not invent. Mature programmes keep both.
Permanent test points suit a continuous schedule. Packaged, agentless runs suit a quick baseline or a network where agents are hard to deploy. Ask which model matches the cadence you actually want.
Pick a handful of techniques across endpoint and at least one other control. Record blocked, detected, logged only, and missed. Change one rule. Retest the same technique. That delta is the pilot.
A scoped pilot can show missed techniques in days. Programme value shows up when those misses are fixed, retested, and stay fixed on the next scheduled run — usually inside the first quarter if an owner exists.
