Understanding Red Team Assessments and Offensive Security Testing

Red team testing is a comprehensive, adversarial assessment that goes far beyond traditional penetration testing. CodeShield’s experts simulate determined attackers, using any means necessary to test your organisation’s true security posture across people, processes, and technology.

During testing, CodeShield’s red team will employ a variety of techniques, including social engineering, phishing attacks, network security testing, physical security breaches, and more in attempt to reach the objective which has been outlined in scoping.

Red team testing

What you get with CodeShield’s red team testing:

  • Detailed reconnaissance to map potential attack paths to your key objectives

  • Open-source intelligence gathering to identify information an attacker could exploit

  • A combination of network, application, and physical security testing techniques

  • Targeted social engineering and phishing campaigns to assess employee awareness

  • Comprehensive reporting with clear findings and actionable, best-practice remediation guidance

Common Red Team Attack Simulations and Tactics

Red team testing is a specialist service that combines multiple advanced techniques to challenge your organisation’s security from every angle. For example, information gathered through social engineering might be used to breach internal networks, mimicking how real attackers operate.

Every CodeShield red team engagement is tailored to your unique environment and objectives, following a thorough scoping phase.

Common techniques our red team experts use include:

  • Attack planning and pretexting
  • Network penetration testing
  • Phishing attacks
  • Defence evasion
  • Peer monitoring
  • Insider threat simulation
  • Exploitation
  • Physical on-site breach
Common Penetration Test Vulnerabilities

Benefits of red team testing

Thinking about red teaming? Here’s what you gain with CodeShield:

  • Simulate a true adversary targeting your organisation’s most critical assets

  • Get a holistic view of your overall security, not just technical gaps, but also human and physical vulnerabilities

  • Experience real-world attack scenarios to see how your defences hold up under pressure

  • Leverage a combination of advanced techniques for maximum impact and insight

  • Meet and maintain compliance standards such as ISO 27001, GDPR, PCI DSS.

Is red team testing right for you?

If you’re responsible for your organisation’s security, consider:

  • Are there weak points in your defences that haven’t been tested under real-world conditions?

  • Have you gone beyond standard measures to prepare for targeted attacks?

  • How would your business respond to a sophisticated, multi-stage breach?

  • Would your stakeholders value independent assurance of your overall security?


If you’re uncertain about any of these, a red team assessment from CodeShield will provide clarity, confidence, and a roadmap for improvement.

Our Red Team Exercise Process - How We Simulate Real-World Attacks

1. Scoping

Our team works closely with you to define the objectives, rules of engagement, and scope for the red team exercise. This includes identifying key assets, business processes, and potential targets that represent critical areas of risk to your organisation. The scope may include internal and external networks, employees, physical locations, and cloud environments. Clearly defining acceptable and prohibited actions ensures alignment with organisational goals while minimising operational disruptions.

2. Intel Gathering

During this phase, we collect detailed information about your organisation using both open-source intelligence (OSINT) and reconnaissance techniques. This includes identifying key personnel, network infrastructure, exposed assets, email addresses, and potential attack vectors. The gathered information is used to plan realistic attack scenarios that mimic the tactics, techniques, and procedures (TTPs) of advanced threat actors targeting your organisation.

3. Planning & Preparation

Our team develops a strategic plan for executing the red team engagement based on the intelligence gathered. This includes designing scenarios to test various aspects of your defences, such as social engineering, phishing campaigns, lateral movement within networks, and physical access attempts. The plan is tailored to simulate real-world attack methodologies while ensuring the safety and integrity of your systems and data.

4. Attack Execution

This phase involves executing the planned attack scenarios to test your organisation’s detection, response, and resilience. Our team uses stealthy and sophisticated techniques to gain access, maintain persistence, and achieve predefined objectives, such as accessing sensitive data or compromising critical systems. The engagement may include phishing attempts, exploitation of vulnerabilities, privilege escalation, and lateral movement. Activities are designed to stay within the agreed-upon scope while accurately simulating real-world adversaries.

5. Detection & Response Evaluation

During the engagement, we continuously monitor how your organisation’s security controls, monitoring systems, and incident response teams react to the simulated attacks. This assessment provides valuable insights into the effectiveness of your detection and response capabilities, highlighting strengths and areas for improvement. If necessary, we adapt our tactics to further test your defences in a controlled manner.

6. Reporting

We document the red team engagement in a comprehensive report that outlines the attack scenarios, techniques used, and objectives achieved. The report details how vulnerabilities were exploited, highlights gaps in detection and response, and provides actionable recommendations to address identified weaknesses. Each finding is contextualised to help prioritise remediation efforts and enhance your organisation’s overall security posture.

7. Debriefing

The engagement concludes with an in-depth debriefing session where we review the results with your stakeholders. This session provides a walkthrough of the attack scenarios, demonstrates the methods used, and discusses the implications of the findings. We offer tailored recommendations to improve your defensive capabilities and build resilience against real-world threats. Questions and discussions during this phase ensure a clear understanding of next steps and long-term security improvements.

Frequently asked questions (FAQs)

While a penetration test is a focused cyber security assessment intended to identify, exploit, and report vulnerabilities on a target area such as networks and applications. A Red Team Operation is typically an extended engagement conducted over a longer period designed to achieve a set objective such as data exfiltration. An organisations detection and response procedures are evaluated during the process. Unlike common penetration testing engagements, red team exercises follow a black-box methodology to as accurately as possible simulate a genuine attack.

While all companies can benefit from a red team exercise, its typically recommended for companies who have an established security system in place and already conduct regular penetration testing. Our expert team of security consultants will be able to advise you on the best approach for your business to maximise the value from your engagement.

The duration of a red team operation can differ depending on the scope and desired objectives of each company. An accurate length of time can be concluded following a 30–60-minute scoping call with one of our penetration testers.

While we cannot guarantee there will be no disruption all our engagements are designed to have as little as possible and be non-destructive while still having the best opportunity to maximise results. We are sure to follow pre-agreed rules of engagement and uphold strong legal and ethical standards throughout all our projects.
