Security leadership
that builds trust.
I'm Justin Kolker — a cybersecurity leader and CISSP who helps organizations protect what matters and build security teams that last. From the boardroom to the threat surface, I turn risk into clear, defensible decisions.
Two decades turning complex risk into calm, confident operations.
I've spent my career at the intersection of leadership and deep technical security work — managing teams, shaping strategy, and staying close enough to the details to make sure the strategy actually holds. I believe the best security programs are the ones people barely notice, because they simply work.
My focus areas span vulnerability and configuration management, network and cloud security, application penetration testing, and compliance and audit response. But the through-line is people: I build teams that are curious, accountable, and genuinely good at what they do.
I'm based in Connecticut, hold the CISSP, and care about mentoring the next generation of practitioners as much as I care about the next threat on the horizon.
