About
Johnathan Drozdowski — Senior Red Team Specialist and founder of Red Spectrum.
Johnathan Drozdowski is a Senior Red Team Specialist with 12+ years of experience operating across government, defence, and enterprise environments — from Canadian Armed Forces networks and classified military infrastructure to large-scale financial sector AD estates.
Red Spectrum exists because most security assessments answer the wrong question. A list of findings tells you where you’re vulnerable. A well-executed red team engagement tells you whether your people, processes, and controls would actually stop a determined attacker — and what they’d miss if they didn’t.

Why Red Spectrum
A “red spectrum” is the full visible range of where adversaries operate — from quiet recon on the dim end, to active intrusion in the middle, to loud post-exploitation at the bright end. Most security programs only watch part of that range. Red Spectrum’s job is to walk the whole thing, and leave clients with a map of where they’re actually exposed.
