Red teaming & adversarial testing · UK

Red teaming that tests whether you’d actually stop an attack.

Objective-led red team exercises that test your people, processes and technology together — showing whether your organisation would detect and respond to a realistic, intelligence-led attack.

Why it matters

A penetration test finds vulnerabilities. A red team tests your defences.

Penetration tests are designed to find as many weaknesses as possible in a defined scope. Red teaming asks a different question: could a realistic attacker achieve a specific objective without being stopped — and would your team notice?

Our red team exercises emulate the tactics, techniques and procedures of relevant threat actors, informed by our threat intelligence work. They test your detection, response and decision-making as much as your technology.

What we test

People, process and technology.

Scenarios are built around objectives that matter to your business.

Threat intelligence

Scenarios based on the actors and techniques most relevant to your organisation.

Initial access

Realistic routes in, such as phishing, exposed services or compromised credentials.

Social engineering

Testing how people and processes respond to targeted manipulation, where in scope.

Persistence & evasion

Whether an attacker could establish a foothold without being detected.

Lateral movement

Movement through your environment towards agreed objectives.

Objectives

Agreed goals — such as access to client data or payment systems — that demonstrate impact.

Detection

Which attacker actions your security monitoring detects, and how quickly.

Response

How your team, processes and providers respond under realistic conditions.

Purple teaming

Working with your defenders afterwards to replay the attack and improve detection.

Methodology

How we test.

AI-assisted speed for the repetitive work. Senior, manual testing for judgement, exploitation and evidence.

Plan

Agree objectives, scenarios, rules of engagement and a control group.

Intelligence

Build scenarios from relevant threat intelligence.

Execute

Emulate the attack, stealthily, towards the agreed objectives.

Replay

Purple team the attack with your defenders.

Report

Attack narrative, detection gaps and improvement plan.

Testing approaches

Choose the right starting point.

Full red team

End-to-end, objective-led exercise from initial access, with minimal knowledge in your organisation.

Popular

Assumed-breach red team

Starting from a compromised user, focusing time on detection and response inside your environment.

Purple team exercise

Collaborative, transparent testing with your defenders to validate and improve detection.

What you receive

Evidence you can act on — and share.

Executive summary

Plain-English risk, business impact and priorities for leadership and boards.

Attack paths

How individual weaknesses chain together into real-world impact.

Technical findings

Evidence, CVSS scoring and specific, practical remediation for every finding.

Live findings

Findings published to the SMARTSEC client platform as the engagement runs.

Retest

Independent revalidation of fixes, with retest terms agreed in the statement of work.

Debrief

A walkthrough of the results with your technical team and stakeholders.

Common findings

What we typically find.

Examples of the issue types this kind of test regularly uncovers — illustrative, not client data.

  • Initial access through phishing or exposed services
  • Attacker activity that generates no alerts
  • Alerts raised but not escalated or acted on in time
  • Privilege escalation through Active Directory weaknesses
  • Access to critical data or systems through legitimate tools
  • Gaps between security providers and internal teams
  • Incident response plans that break down in practice
  • Weak controls over sensitive business processes
Compliance & assurance

Evidence for the people who ask.

  • Boards and regulators — evidence of how the organisation would perform against a realistic attack.
  • FCA operational resilience — severe but plausible cyber scenarios tested end to end.
  • Security investment — objective evidence of what your detection and response actually achieve.
  • DORA TLPT and TIBER-EU — for these regulated tests we act as the independent threat intelligence provider, separate from the red team.
FAQs

Red teaming questions.

What is red teaming?

An objective-led exercise that emulates a realistic attacker to test whether your organisation can prevent, detect and respond to an attack — covering people, processes and technology together.

What is the difference between red teaming and penetration testing?

A penetration test aims to find as many vulnerabilities as possible in a defined scope. A red team exercise pursues specific objectives, often stealthily, to test detection and response.

Who knows about the exercise?

Only a small control group in your organisation, so the response of your defenders is realistic. Rules of engagement and safety controls are agreed in advance.

Do you include social engineering?

Where it is in scope and agreed with you, social engineering such as targeted phishing can be included.

How long does a red team exercise take?

Red team exercises are scoped individually based on objectives and scenarios, and typically run over several weeks.

Can you act as the red team for a DORA TLPT or TIBER-EU test?

For DORA TLPT and TIBER-EU, we act as the independent threat intelligence provider. The frameworks separate this role from the red team provider.
