Rebel Cybersecurity

About

Rebel Cybersecurity delivers cybersecurity expertise without dilution, distractions, or mass-market nonsense. Founded by Alex Negvesky, the firm works with a deliberately small group of clients, giving every engagement senior-level attention from a single practitioner. Rebel Cybersecurity partners with professional services firms such as financial advisors, law firms, and accountants, working as a fractional vCISO to protect their clients, data, and reputation without the cost of a full-time security executive. That standard carries into the firm's Reg S-P work with RIAs, building security programs that hold up under real examination scrutiny.

Rebel Cybersecurity brings over two decades of hands-on experience in cybersecurity and IT leadership to businesses across Orange County. My background spans program management, architecture, engineering, and operations, with much of my career spent helping financial-sector firms meet regulatory expectations without unnecessary disruption.

My focus is simple: clear, practical cybersecurity guidance that small and midsize businesses can trust and use. No fear, no hype, no jargon meant to sell you tools you don't need.

For Registered Investment Advisers, I provide focused help with SEC Regulation S-P. The compliance deadlines have passed, and the question now is whether your program holds up under examination. I help firms validate what they've built, close the gaps an examiner would find, and keep their program exam-ready over time. When a firm is already in an exam, I work alongside its legal and compliance leaders on the technical substance of its response.

Rebel Cybersecurity was founded to push back against the fear, hype, and confusion that dominate this industry. You get honest expertise, straightforward direction, and a partner committed to strengthening your security without overcomplicating it. Serving Irvine, Newport Beach, and the surrounding areas.
