What is red teaming? What is red teaming?

What is red teaming?

Red teaming is an adversarial, threat-led method of security testing. A red team test aims to breach your defences by employing genuine tactics, techniques and procedures that a real-world cyber criminal would use. This goal-oriented-driven approach more accurately simulates an attack by a persistent threat actor on your cyber defences and security team.

Bulletproof red team pen testers use social engineering, penetration testing tools and creative thinking to identify vulnerabilities in networks, systems, buildings, people and processes. This makes red team assessments comprehensive in nature, providing an extensive insight into your business's security.

Bulletproof divides red team testing into the following distinct attack scenarios, each with its own aims and security outcomes:

  • Red Team
  • Black Team
  • Purple Team
  • Assumed Breach
  • EDR/XDR Evaluation

Benefits of red team testing

Red Team

Put your defences to the test against a real, persistent adversary.

Red team penetration testing is the only way to truly gauge how your business’ security defences react to a real-world threat. By simulating the resources and tools available to a determined adversary, red teaming reveals security flaws that you didn’t know you had. Red teaming is the most comprehensive security test available and demonstrates your commitment to business security.

All Bulletproof red team engagements are tailored to your specific business and objectives, providing an unrivalled training opportunity for your defensive teams and systems. Our approach, based on real world threats, is designed to evaluate the people, processes and technology within your organisation.

Black Team

Put your physical security defences to the ultimate test.

The aim of black teaming is to gain access to a restricted physical space, such as a particular office or data centre. Bulletproof’s skilled back team pen testers will use all tools at their disposal to model a determined, persistent adversary aiming to breach your physical defences. Find out how resistant your people, processes and technology are to social engineering, ethical hacking, tailgating, pretexting and much more.

Purple Team

Take a collaborative approach to improve the detection & prevention capabilities of your organisation.

Purple teaming simulates a wide range of techniques, tactics and procedures in a safe and collaborative way. Both red and blue teams work together to evaluate individual offensive actions commonly taken during a real-world attack, with the goal of remedying any issues. Purple team testing gives you a comprehensive overview of detection and response gaps mapped to industry-standard frameworks, such as MITRE ATT&CK.

Assumed Breach

Move beyond classic authenticated penetration testing by using an objective & impact driven approach.

Assumed breach testing operates under the simple principle that a breach can and will happen. It is designed to identify how well your defence in depth would limit a real-world attacker and the effectiveness of protecting your critical business functions. Testing is objective driven and uncovers what an attacker can achieve via device compromise or other attack vector.

Why your organisation needs red teaming

Red teaming is a powerful way to expose hidden threats and strengthen your security from the inside out. It gives your security team the insight to help you protect your valuable data and assets from targeted attacks.

Organisations of all sizes can use red teaming attack scenarios to better understand your security posture and assess how your organisation would defend against a determined and resourceful adversary. A key benefit is the ability to uncover blind spots caused by bias and assumptions, which can go unnoticed by other types of security testing. This makes a red team assessment a great way to test and improve your incident response capability.

What’s the difference between red teaming and a penetration test?

A Penetration tests attempt to find security vulnerabilities in a specific set of IT systems, whereas the goal of a red team assessment is to compromise your security defences using real techniques and tooling used by determined adversaries. The objective-based nature better simulates an attack from a determined cyber criminal against your networks and security controls. Red teaming can be combined with black teaming to provide a complete assessment of your organisation’s security posture.

Bulletproof’s experienced, adversarial tradecraft tests every layer of your organisation’s defences to provide a complete overview of your security risks. Red teaming is the most in-depth security assessment available, and an ideal way to strengthen systems across your business while showing your clients and stakeholders that you take security seriously.

While a red team uses tactics techniques and procedures (TTP) to simulate a real-world threat, a blue team is positioned within the network to recognise unusual behaviour and defend against an attempted attack. Bulletproof’s collaborative purple team assessments provide proof of concept attacks that show how an attacker could gain access to a specific system or set of systems, involving a blue team at various stages to recognise and monitor the attack as it proliferates through the network. A purple team assessment is the best way to assess the effectiveness of your blue team.

Absolutely. Bulletproof welcomes the opportunity to collaborate with organisations who have their own blue teams established, and coordinating the exercise is a great way to test the effectiveness of your current security controls and for understanding attack paths that may make your systems vulnerable to an external breach. These Purple Team engagements pit our experienced adversaries against your cyber defenders, with the goal of uncovering all threat detection and response weaknesses.

Red teaming is ideal for businesses who have an established security systems in place and already carry out regular penetration testing on their networks. However, organisations of any size and stage in their development can benefit from Red Team exercises. Our experienced security consultants will be able to advise you on exactly what will work for your business, and how to get the most value from your engagement.
