Kenosha Deserves Better Network Security
Multi-site networking, SD-WAN, and secure branch connectivity — built for how Kenosha businesses actually operate.
Kenosha businesses often have headquarters on one side of town, a warehouse by I-94, remote employees in northern Illinois, and sales reps connecting from the road — every connection point a potential entry for an attacker. Powerful IT Systems provides network security that covers all of it: SD-WAN for multi-site connectivity, managed firewalls with intrusion detection, VLAN segmentation isolating sensitive data from guest traffic and IoT devices, and industrial-grade wireless designed for warehouse environments with RF surveys. We also deploy site-to-site VPN for cross-state operations and monitor your network 24/7 for anomalies. Based in Sussex, all network security is included in our flat-rate managed IT plans. No contracts.

Quick IT Tips
Practical advice for Kenosha businesses — whether you work with us or not.
- •Check your firewall rules. If they have not been reviewed in the last 12 months, they probably have rules that are outdated, overly permissive, or no longer relevant to your business.
- •Segment your guest WiFi from your business network. If a visitor's infected laptop is on the same network as your file server, you have a problem.
- •If you have multiple locations, test your failover. Disconnect one ISP connection and see if traffic routes correctly. If nobody has tested it, it probably does not work.
- •For warehouse environments, do not guess on wireless coverage. Get an RF site survey done — metal racking, concrete walls, and high ceilings create dead zones that consumer-grade access points cannot overcome.
- •Review your ISP contracts annually. Bandwidth pricing drops over time, and you may be paying 2019 rates for a connection that should cost half as much today.
