How to Get a Better Cyber Security Job After a Lay-Off or Redundancy

Redundancy is never easy—especially in a fast-moving field like cyber security, where your skills and experience are constantly evolving. But if you’ve recently been made redundant from a cyber security role, know this: the UK cyber workforce remains in high demand, and your expertise is more valuable than ever. Whether you’re a SOC analyst, penetration tester, incident responder, security architect or GRC specialist, there are still thousands of opportunities across sectors including finance, defence, government, retail, and critical infrastructure. This guide will help you turn redundancy into a career relaunch, with a clear action plan tailored to the UK cyber security job market.

Cyber Security Jobs Salary Calculator 2025: Check Your Market Value in Seconds

Why yesterday’s pay survey no longer protects you. “Could I earn more at a managed SOC?” “Is that fintech’s offer really competitive?” Every UK cyber‑security professional asks some version of those questions—usually after another colleague lands a pay rise, a recruiter sends a tempting JD, or a fresh breach makes headline news. Yet salary guides published even last year feel as out‑of‑date as a forgotten antivirus signature. Since 2024, ransomware gangs switched to double‑extortion, deepfake phishing exploded, & the EU’s NIS2/DORA regulations bled into UK contracts despite Brexit. With each shift, salary bands move. To cut through stale averages, CybersecurityJobs.tech distilled a three‑factor formula that lets you estimate a realistic 2025 salary in under a minute. Feed in your role, your UK region, & your seniority level. The output arms you with data‑driven leverage for your next appraisal, job application, or freelance rate card. This article explains the formula, reveals the forces pushing cyber pay ever higher, & outlines five practical moves to boost your market value within ninety days.
