What is Attack Simulation?

What is Attack Simulation?

What is Attack Simulation?
Attack Simulation (or Red Teaming) is a threat-led, adversarial security testing method that simulates real-world cyber attacks.
It is goal-driven and aims to breach your defences using tactics, techniques and procedures employed by real threat actors to closely mirror a persistent attack against your cyber defences and security team.
Attack Simulation vs Penetration Testing
Attack Simulation is scenario-driven, simulating real-world cyber-attacks to test your organisation's overall security posture, including people, processes, and technology.
Penetration Testing is vulnerability-driven, focusing on identifying and exploiting flaws in specific systems.

Our services
Red Team Engagement
Our classic end-to-end engagement simulates a real-world breach, mirroring the tactics, techniques, and procedures (TTPs) of genuine adversaries.
We deploy evasion techniques and covert delivery to expose security gaps and help blue teams respond effectively.
Threat-Led Penetration Testing
We design intelligence-driven attack simulations around your organisation's unique threat landscape to replicate realistic attack scenarios.
We simulate the tactics most likely to target you and assess your ability to detect, respond and recover.
Assumed Breach Assessment
We simulate a post‑exploitation scenario to evaluate how well your organisation detects, responds to and contains internal threats.
By focusing on lateral movement, privilege escalation, and impact delivery, we stress-test your defences and validate controls.
Purple Team
Our offensive (Red Team) specialists collaborate with your defensive (Blue Team) experts to evaluate and strengthen your organisation’s threat detection and response capabilities.
Both teams track actions and outcomes in our interactive portal to generate clear, actionable insights.
Continual Threat Service
A proactive, ongoing engagement designed to monitor and assess your organisation’s external attack surface in real time.
We launch persistent, targeted attacks timed for maximum effect, keeping your defences tested against real-world adversary tactics.
EDR & XDR Evaluation
We assess the effectiveness of your endpoint detection and response (EDR) or extended detection and response (XDR) platforms.
Our structured, evaluation covers detection accuracy, response effectiveness, telemetry granularity, alert context, and analyst usability.
How we work
This represents a standard workflow for a Red Team engagement.
Engagements with dedicated threat intelligence providers may use a modified workflow aligned with specific frameworks and your organisation's needs.
We have a fact-finding conversation with you to understand your needs and objectives.
We generate a custom proposal that includes cost information and a detailed engagement plan.
Once you accept the proposal, we will assign a team and schedule your engagement.
Our consultants hold a scoping workshop to define boundaries and objectives and fully map out all aspects of the engagement before launch.
Our team executes the engagement according to the agreed plan and engages in constant communication with all involved parties.
We hold a post-assessment workshop to discuss findings. Our team provides recommendations and offers training to your defensive teams.
We remain available to provide support and answer any questions you may have after the engagement.
