The Person Behind CNE Defense

CNE Defense is the defense-contractor practice of Computer & Network Expert, an IT consultancy based in Simi Valley, California — serving Ventura County, the Los Angeles metropolitan area, and defense contractors nationwide.

It's run by Nick Duymayan, who has been building and securing business networks since 2002 — over two decades of hands-on infrastructure, security, and compliance work.

CNE Defense is a Microsoft, Dell, and HP partner.

What makes this practice different:

Specialized, not generalized. CUI enclaves, ITAR data handling, and government cloud are the daily work here — not a sideline bolted onto residential IT.

Quality over quantity — by choice. We deliberately keep our client list small. Fewer clients means deeper knowledge of every environment we protect, faster answers, and better outcomes. You work with the person who does the work — no account managers, no ticket queue purgatory, no junior tech learning on your network.

Plain English, always. If you can't explain a control to your shop foreman, it won't survive an assessment. Every deliverable is written to be understood.

U.S.-person operations. Export-controlled data is handled accordingly, start to finish.

Handling CUI and not sure you're covered?
