Your Business Challenges

Our Red Teaming services are aligned to the challenges your organisation faces. 

Unsure of the risks you face

Without clear insights into where your cyber security posture can be improved, it’s difficult to understand the risks your organisation faces.

Uncertain how you would respond to a real attack

It’s great to know that your organisation’s cyber defences can stand up to penetration testing, but how would you respond to a real attack? What if a phishing email bypassed filters or an employee unknowingly allowed unauthorised access?

Conduct ethical hacking within your organisation

Ethical hacking, also known as penetration testing or white-hat hacking, involves authorised experts simulating real-world cyber-attacks to identify exploitable weaknesses within an organisation’s systems, networks, or applications. Unlike malicious hackers, ethical hackers use their skills to help organisations strengthen their cyber defences, ensuring compliance with standards such as GDPR and ISO 27001. Ethical hacking plays a vital role in Red Teaming, where technical, physical, and social engineering attack methods are combined to assess the effectiveness of an organisation’s security measures.

Need support with security migration

Once you’ve established your cyber security gaps, you need an experienced partner to support you in carrying out the mitigation activities.

Penetration Testing vs Red Teaming

While both Penetration Testing and Red Teaming focus on identifying vulnerabilities within an organisation, their objectives and methods are different. Penetration Testing is typically a scoped, structured assessment designed to find and exploit specific vulnerabilities in a defined area, such as an application, network, or system. Its goal is to provide organisations with a detailed understanding of exploitable weaknesses and recommendations to fix them.

Red Teaming, meanwhile, takes a broader and more adversarial approach. It simulates real-world cyber-attacks to test an organisation’s overall security posture, including its defences, detection capabilities, and incident response processes. Red Teaming focuses on stealth, persistence, and bypassing security controls to mimic the tactics, techniques, and procedures (TTPs) of advanced threat actors. While Penetration Testing is akin to checking the locks on your doors and windows, Red Teaming is like hiring someone to break into your house by any means necessary.

Within teaming there are multiple colour coded teams which all can be conducted at the same time depending on the test goals – the most common are red, blue and purple. 

Red Team, Blue Team and Purple Team

A Red Team’s focus is on offence while a Blue Team’s remit is defending. The Purple Team can be introduced within a Red Teaming campaign to optimise and support the process. The collaboration between Red Team, Blue Team, and Purple Team within Red Teaming will help assess a cyber security posture to its limits and form an actionable strategy an organisation can use to improve upon.

  • Read Team: The offensive security experts simulate attacks, aiming to exploit vulnerabilities, bypass defences, and achieve specific objectives—such as gaining unauthorised access to sensitive data or areas. Their role is to challenge the security framework and test real-world readiness against potential adversaries.
  • Blue Team: This team is responsible for defence. They monitor systems, detect threats, and respond to security incidents. Their primary focus is on maintaining the integrity, availability, and confidentiality of organisational assets by stopping attacks and mitigating risks – actively attempting to thwart a Red Team’s attack.
  • Purple Team: The Purple Team, analyses how the teams work together, offering recommendations for future or current engagements or pushing the Red Team to test and target specific elements of the Blue Team’s defence capabilities. The Purple Team will often review the results and oversee the changes needed to improve security measures.

Together, these roles form a dynamic cycle of testing, learning, and improving, enabling organisations to stay resilient in the face of ever-evolving threats.

Simulate Cyber Security Attacks with Our Readiness Scenarios

Our Readiness Scenarios allow you to gain elevated insight by leveraging our pre-prepared scenarios that are more familiar to the types of tests you may have experienced through a regular Penetration Testing engagement, but with an approach that goes way beyond a standard test and really looks at your organisation through the eyes of an attacker. These testing frameworks simulate attack vectors like ransomware deployment or credential harvesting, offering real world insights that go beyond traditional penetration testing. 

We offer nine different types of Readiness Scenarios, each focusing on a familiar attack vector, and each commonly used in a full Red Teaming event. Our approach is the same as our approach when carrying out a full Red Teaming exercise, but the scope is already defined and packaged for you, allowing the scenario to be carried out efficiently, bringing you results quickly. We also offer Penetration Testing as a Service that delivers regular, proportionate testing and enhanced security posture visibility.

Frequently Asked Questions - Red Teaming

What is Red Teaming in cyber security?

Red Teaming is a cyber security practice that simulates real-world attacks to evaluate and test an organisation’s security strategy. It involves ethical hackers (the "‘Red Team") ’) using adversarial tactics, techniques, and procedures (TTPs) to test how well your systems, processes, and employees respond to sophisticated cyber threats.

How is Red Teaming different from Penetration Testing?

While penetration Penetration Testing focuses on identifying vulnerabilities within specific systems or applications, Red Teaming takes a broader approach. It simulates end-to-end attack scenarios, targeting people, processes, and technology to uncover weaknesses across your organisation’s entire cyber security posture, including its response to an attack. Red Teaming is often conducted over a longer period of time and provides insight into the overall security posture.

Who conducts Red Teaming exercises?

A Red Team is made up of certified and professional ethical hackers, often certified by industry-recognised organisations such as CREST or NCSC. These experts use advanced real world tactics to mimic the methods of real-world adversaries, ensuring accurate and actionable findings.

What are the benefits of Red Teaming?

Red Teaming provides an organisation a with realistic assessments of how secure they truly are. Red Teams will provide a host of benefits for an organisation. • Identifying overlooked vulnerabilities across your organisation. • Testing incident response procedures in real-world scenarios. • Strengthening overall cyber resilience. • Reduce social engineering attacks and raise awareness. • Improving employee awareness of overall cyber security threats.

How does Red Teaming work?

Red Teams do not use a singular approach to penetrating security measures, instead using real world tactics to test your organisations security. A typical Red Teaming engagement involves - 1. Planning and Scoping: Defining objectives, rules of engagement, and testing scope. 2. Reconnaissance: Gathering intelligence about your organisation to identify potential attack vectors. 3. Execution: Simulating attacks using real-world techniques. 4. Reporting: Delivering a detailed report of findings and recommendations for remediation.

How long does a Red Teaming assessment take?

Between two-to-six weeks. The duration varies based on the scope and complexity of the engagement. Typically, Red Teaming exercises last between two weeks and six weeks, sometimes even several months, depending on the objectives, scope, and organisational size.

Do I need regular red Red Teaming assessments ?

Red Team assessments should be a regular part of an organisations cyber security strategy. Organisations should conduct Red Teaming exercises annually or after significant changes to their infrastructure, such as new system implementations, mergers, or updates to security policies.

Is Red Teaming necessary for compliance?

While not always mandatory, Red Teaming can help organisations meet specific regulatory requirements (e.g., GDPR, PCI DSS) by being proactive with their security measures and incident response readiness.

Does Red Teaming disrupt normal business operations?

No, Red Teaming engagements are carefully planned to minimise disruption. The testing is conducted within defined rules of engagement, ensuring that critical systems and services remain operational throughout the exercise to minimise disruption to the business.

What deliverables can I expect from a Red Teaming exercise?

Deliverables from a Red Tteaming exercise will include a comprehensive report that contains : • A summary of simulated attack scenarios. • Identified vulnerabilities and attack paths . • Recommendations for remediation and strengthening defences. • Insights into your incident response capabilities.
