A red-team assessment tests whether an organisation can prevent, detect and respond to a realistic multi-stage intrusion against defined business objectives. It is intended for mature organisations that already operate foundational controls and want to test integrated defensive performance rather than isolated vulnerabilities.
The purpose is to validate realistic attack paths safely and convert technical weaknesses into remediation priorities.
The final scope is agreed before work begins. Depending on the objective, environment and authorised access, the engagement may cover:
Agree target outcomes, threat model, scope, deconfliction, stop conditions and legal authority.
Select realistic techniques, infrastructure, pretexts and success criteria.
Operate discreetly while protecting production stability and sensitive data.
Record what was prevented, detected, investigated, escalated or missed.
Reconstruct the operation, prioritise gaps and convert findings into detection and response actions.
Deliverables are written for decision-makers and the teams responsible for implementation. Depending on scope, they may include:
Testing is governed by written authorisation, explicit exclusions, safety limits and emergency contacts. Material findings are manually validated, supported with reproducible evidence and explained in terms of realistic impact rather than scanner severity alone.
The engagement may draw on MITRE ATT&CK, red-team rules-of-engagement practice, relevant threat intelligence and customer control frameworks. A framework reference explains how the work is organised; it does not by itself represent certification, accreditation or a regulatory decision.
The schedule is confirmed after scoping and depends on the environment, evidence available and stakeholder access.
Red teaming carries higher operational and reputational risk than a standard penetration test. It requires explicit executive sponsorship, legal authority, deconfliction, stop conditions and agreement on sensitive techniques. It cannot guarantee that every real attacker would be detected or blocked.
Discuss Red-Team Assessments with CTG. A focused scoping session will confirm the objective, boundaries, evidence, delivery model and expected outputs before a proposal is issued.
The final scope is agreed before work begins. Typical areas include threat-informed objectives and target assets, External, application, identity and internal attack paths, Email, telephone or physical pretexts when explicitly authorised, and Command-and-control and persistence techniques within safety limits. The proposal records exclusions, required access, customer responsibilities and acceptance criteria.
Deliverables depend on the agreed objective and may include red-team operation plan and rules of engagement, Executive attack narrative and objective status, Technique timeline mapped to observed defensive response, and Evidence of control and detection gaps. Material conclusions are linked to supporting evidence, impact, priority and accountable next steps.
Authorised testing can create risk if it is poorly controlled. CTG agrees testing windows, prohibited techniques, stop conditions and emergency contacts before work begins, and uses higher-risk techniques only with explicit approval.
Retesting can be included in the initial scope or ordered after remediation. It validates the previously confirmed findings and closely related bypass conditions; it is not automatically a complete new assessment.
The schedule is confirmed after scoping and depends on the environment, evidence available and stakeholder access.
The services answer connected but different questions. Scoping identifies whether Red-Team Assessments, External and Internal Penetration Testing, or a coordinated programme is the smallest useful approach without duplicating work.
