Get in touch

Our red teaming services provide a proactive way for you to evaluate and enhance your cyber security.

By simulating real-world cyber-attacks, our red teaming services help identify weak spots, test your security measures, and enhance your threat detection and incident response. Our comprehensive assessments include vulnerability testing, social engineering simulations, and physical security evaluations to uncover risks across your organisation. By collaborating with your internal and external security teams, we strengthen your defences against sophisticated threat actors.

What is Red Teaming?

Red teaming is an advanced form of security testing where ethical hackers simulate real-world attacks to uncover vulnerabilities in your defences. Unlike traditional assessments, it mirrors the tactics of genuine adversaries to evaluate detection and response capabilities.

Going beyond penetration testing, red teaming combines attack simulations with threat intelligence to expose gaps before attackers exploit them. Red teams challenge internal defence teams (blue teams), and when they collaborate, it becomes purple teaming – driving continuous improvement in threat detection and response.

Our ongoing red teaming services help organisations stay ahead of evolving threats by identifying weaknesses, delivering actionable insights, and strengthening overall security posture.

Frequently Asked Questions

How often should a Red Team exercise be conducted?

You should conduct this cyber security assessment regularly, typically every year. This frequency ensures you stay ahead of potential threats and continuously improve your security posture. However, if your organisation undergoes significant changes, like system upgrades or mergers, consider additional exercises. Consistency is key to identifying vulnerabilities and enhancing your defences. We can help collaborate with your team to determine the best schedule for your unique needs.

What industries benefit most from Red Teaming services?

Industries that benefit most from red teaming services include finance, healthcare, and biotech. These sectors handle sensitive data and critical systems and are common targets for cyber attacks. Regular testing helps you identify attack vectors, assess vulnerabilities, and improve your security posture. Red teaming acts as the ultimate test of your organisation’s defences, including both technical systems and physical intrusion safeguards.

Can Internal IT teams perform Red Teaming effectively?

You might wonder if your internal IT team can perform red teaming effectively. While they know your systems well, they may lack the objectivity needed to identify all vulnerabilities and attack vectors. Outside experts bring a fresh perspective and specialised skills, including testing incident response procedures and physical security. With the right training and tools, your IT team can complement external red teaming efforts, enhancing overall security. Collaboration between internal and external red and blue teams often yields the best results.

How are Red Team findings reported to stakeholders?

We typically report findings to key stakeholders through detailed, yet clear, documentation and presentations. Reports include an executive summary highlighting critical issues and their impacts, followed by a deeper dive into each finding with evidence, risk level, and recommended actions. Visuals such as charts and graphs help communicate complex attack vectors. Our reports ensure stakeholders can understand the results and make informed decisions to improve security and refine incident response procedures.

How is Red Teaming different from Penetration Testing?

While penetration testing focuses on finding specific vulnerabilities in systems or applications, red teaming takes a broader approach by simulating an entire attack scenario, including tactics, techniques, and procedures (TTPs) of real-world adversaries. Red teaming tests your overall defences, including people, processes, critical systems, and physical security measures, providing the ultimate test of your organisation’s resilience.
