Taking Simulation Attacks to the next Level

Of all the cyber security assessments available, this type of simulated attack takes security testing further.

Going one step beyond a penetration test, red teaming is an in-depth assessment of your organisation’s technical and physical detection and response capabilities, viewed through the eyes of an adversary.

By examining the risks and vulnerabilities within your organisation, this assessment is designed to stress-test internal teams and their procedures, preparing them for a potential cyber security event.

How Will You Benefit?

Identify existing risks to business assets
Understand your organisation’s ability to detect and respond to sophisticated and targeted threats
Work closely with an expert incident response team
Gain meaningful mitigation insights and comprehensive post-assessment reports
Build stronger defences to prevent a real-world breach

Red TEam Testing Framework

A red team attack simulation is typically structured in different phases that mimic a real-world scenario as closely as possible. Security policies could be assessed after the office has closed for the day, and tests will certainly be carried out at varying times, to accurately picture a companies complete security posture. Our red team assessments are typically carried out in five core stages.

Stage One

Reconnaissance and planning

Stage Two

Social engineering TTPs (techniques, tactics and procedures)

Stage Three

Wi-Fi access testing and network assessments

Stage Four

Onsite attack scenarios, such as USB drops

Stage Five

Delivery of findings and reporting

Physical Security Testing

Looking to also test your physical defences?

We offer a variety of complementary offensive security services, one of which is a Black Team Assessment (also known as a physical penetration test).

This type of assessment challenges the tangible aspects of an organisation’s defences. With this, you can gain insight into:
How access is controlled to the network/server room
Whether malware could be installed manually on your PCs
If your employees are adequately trained to deal with a physical attack
Whether an adversary could walk out unnoticed if given unrestricted access to your offices
What the consequences of a physical attack could be

Red Teaming FAQs

What is a Red Teaming Assessment and how can it protect my business?
A Red Teaming Assessment is an advanced security testing technique that simulates realistic cyber-attacks using sophisticated tactics. It goes beyond traditional vulnerability assessments and penetration testing by emulating attack scenarios, techniques and strategies employed by skilled adversaries.

Red Teaming identifies security weaknesses, assesses detection and response capabilities and takes a holistic approach to evaluating an organisation’s overall security posture. It helps improve incident response, mitigates risks and enhances resilience against targeted threats.
