Offensive Security

Adversary Simulation

Think like an attacker: validate your defences end to end with red teaming, purple teaming and social engineering.

Periodic penetration testing tells you whether specific systems are hardened. Adversary simulation goes further, measuring how well your defensive and response capabilities withstand a determined attacker across social, physical, network and application vectors. We think like an attacker so you can validate your defences.

A red teaming exercise measures both the effectiveness of your defences and the efficiency of your incident response team in detecting and tracking an attack. Purple teaming replays the engagement collaboratively so your defenders can close detection and response gaps in real time. Social engineering, including phishing, vishing and physical testing, tests the human layer, and readiness exercises such as table top exercises, cyber crisis simulations and cyber drills prepare your leadership and responders. Every scenario is informed by current threat intelligence so it reflects the adversaries your organisation is likely to face.

How we simulate

Red teaming

Full attack-chain simulation across social, physical, network and application vectors while your defenders operate unaware.

Purple teaming

Collaborative attack and defend, replaying the engagement to close detection and response gaps and strengthen playbooks.

Social engineering

Phishing, vishing and physical testing to measure and strengthen the human layer.

Readiness exercises

Table top exercises, cyber crisis simulations and cyber drills that prepare leadership and responders.

Key benefits

Challenge the organisation from a genuine adversarial point of view
Measure how effectively your defences protect against a determined attacker
Assess how quickly your incident response team detects and tracks intrusions
Close detection and response gaps through collaborative purple teaming
Test the human layer with phishing, vishing and physical engagements
Prepare leadership and responders with crisis simulations and cyber drills

How we work

01
Objectives and threat modelling
Define the goals, target assets and adversary profile the exercise should emulate.
02
Threat intelligence and planning
Build realistic attack scenarios and tooling informed by relevant threat intelligence.
03
Multi-vector execution
Attempt to reach the agreed objectives across social, physical, network and application vectors while your defenders operate unaware.
04
Debrief and purple teaming
Replay the engagement with your defenders to close detection and response gaps and strengthen playbooks.
05
Readiness exercises
Run table top exercises, crisis simulations and cyber drills so leadership and responders are prepared for the real thing.
