  • Provide guidance on security in design, development, and implementation phases


Required Experience

  • Proven background incard payment systems, payment processing, or credit card platforms
  • Strong technical understanding of web applications, APIs, authentication, and data security
  • Ability to identify and exploit vulnerabilities manually – beyond commercial tools
  • Knowledge of OWASP Top 10, secure coding principles, and threat modelling frameworks

  • Salary up to £130,000 base + performance bonus

SOC Analyst Jobs UK 2026: Salaries, Skills & How to Get Hired

Cyber security is one of the UK's fastest-growing career paths — and SOC analyst is where most people begin. It's in high demand, genuinely accessible, and you don't need a degree or years of experience to get started. But knowing what UK employers actually want in 2026 — what they pay, which certs matter, and how to stand out — is a different matter. This guide covers all of it.

How Many Cyber Security Tools Do You Need to Know to Get a Cyber Security Job?

If you are trying to build or move forward in a cyber security career, it can feel like the list of tools you are expected to know never ends. One job advert asks for SIEM platforms, another mentions penetration testing tools, another lists cloud security, threat intelligence platforms, endpoint detection, scripting languages and compliance frameworks. Scroll LinkedIn and it gets worse. Everyone seems to “know” dozens of tools, certifications and platforms. Here is the reality most cyber security hiring managers agree on: they are not hiring you because you know every tool. They are hiring you because you understand risk, can think like an attacker and a defender, follow process, communicate clearly and make good decisions under pressure. Tools matter — but only when they support those outcomes. So how many cyber security tools do you actually need to know to get a job? For most job seekers, the answer is far fewer than you think. This article explains what employers really expect, which tools are essential, which are role-specific and how to focus your learning so you look credible, not overwhelmed.
