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.
