Penetration Testing
Ethically attack systems to find and report vulnerabilities. Red-team mindset, hands-on, methodology-driven.
Cyber security is one of the fastest-growing, most in-demand fields in the UK. This guide explains the specialisms, the routes in, and how to progress — without the jargon.
Cyber security is the practice of protecting systems, networks, data, and people from digital threats. It spans offensive work (finding weaknesses before criminals do), defensive work (monitoring and responding to attacks), and governance (managing risk and compliance). It is a career of continuous learning — which is exactly why it suits curious, problem-solving minds.
Ethically attack systems to find and report vulnerabilities. Red-team mindset, hands-on, methodology-driven.
Monitor, detect, and respond to threats in real time using SIEM and EDR tooling. Blue-team frontline.
Design secure systems and networks from the ground up; embed security into technology decisions.
Manage policy, risk, and standards (ISO 27001, NIST) so organisations stay secure and accountable.
Investigate incidents, recover evidence, and lead the response when something goes wrong.
Build and maintain the tooling and automation that keeps defences running at scale.
