Scenario-Based Testing
Controlled scenario testing, starting from an assumed compromise, to validate detection, response, and recovery across realistic attack chains.
Scenario-based engagements answer a more focused question than a full red team: "if a specific assumed-breach event happened, would we contain it before it became a business-impacting incident?". They are shorter, cheaper, and easier to schedule than a full red team, and often produce more actionable findings because the scope is narrower.
Most clients run scenario-based engagements on a yearly cycle, rotating through realistic threat scenarios: compromised SSO, compromised cloud tenant, compromised endpoint, compromised supply chain. The goal is to keep detection and response capability honest against the threat patterns that genuinely matter, not just commodity malware.
What's at stake.
Most breaches start with an existing foothold
A phished workstation, a stolen partner credential, a compromised SaaS account, all are "assumed breach" starting points. Scenario testing measures detection from exactly where real attacks begin.
Targeted scenarios produce sharper findings
Full red team engagements produce broad narratives. Scenario engagements produce targeted operational fixes against specific threat patterns.
What we test.
Common scenarios
- Compromised SSO / identity provider
- Compromised cloud tenant
- Compromised endpoint (standard workstation)
- Supply-chain scenario
- Insider threat simulation
Outcomes
- Detection validation
- Incident response evaluation
- Containment and recovery testing
- Tabletop and live execution variants
- ATT&CK technique coverage assessment
A structured, intelligence-led path through every engagement.
Every engagement follows the same disciplined path through the Velocity platform, so quality, traceability, and reporting are consistent across teams.
Scoping
Define assets, environments, Rules of Engagement, and acceptance criteria with the technical and security stakeholders.
Execution
Manual and tool-assisted testing by CREST-accredited consultants, with evidence captured at each step.
Validation
Every finding is reproduced, risk-rated under CVSS, and confirmed by a second consultant before reporting.
Reporting
Cryptographically signed reports with test-case traceability, severity ratings, reproduction steps, and remediation guidance.
Debrief & Retest
Stakeholder walk-through of findings, prioritisation support, and a retest cycle on remediated issues.
Mapped to recognised baselines.
