Powered by Karajohn Group — the people who've kept your website online, now keeping your property and network secure.
What NetGuard covers
From the camera on your wall to the network it runs on, NetGuard handles the full chain.
HD and night-vision cameras placed where they actually matter, viewable from your phone or laptop.
Door, window, and motion sensors that alert you — and us — the moment something's wrong.
A live team watches every signal around the clock and responds the moment an alarm trips.
Firewalls, secure Wi-Fi, and network hardening for the systems running your business.
How it works
We walk the property, map blind spots and entry points, and check your network setup.
You get a clear plan: camera placement, sensor layout, and equipment — no surprises.
Our technicians install and test everything, then walk you through how it works.
Your systems go live, watched 24/7 by our monitoring team.
