The backbone of your IT infrastructure. Switches ensure that packets of data are reliably and swiftly transmitted between different devices in your network.
Routers are the gateway between your network and the internet. As the name suggests, they “route” the connection between all of your devices and their intended destination on other networks and the internet.
In a fast-changing business landscape where more and more devices are transitioning to wireless connectivity, wireless networks are becoming not only increasingly important, but critical to maintaining the interconnectivity of IT infrastructure and productivity.
In the age of big data, businesses are required to store large amount of data, either willingly or unwillingly to efficiently operate their business. This gives a great liability on businesses to ensure the safety of this data.
Our technology partners have brought to market all-in-one server solutions. These all-in-one server chassis allow for more accessible ways to provide switching, virtualization, computing and storage solutions for your business.
Our partners specialize in getting you up and running on the latest, state-of-the-art communications solutions. Whether it is for conference calls, video conferencing, or getting your entire operations and up and running for remote work.
When it comes to network speed and security, hard lines are still the safest option. We have a vast inventory of cabling solutions that support every interface you may require at varying distances.
Networking hardware doesn’t stop at the core hardware, from stack kits, to stack cables, to redundant power supplies to rack mounts, ensure your project is complete with a wide selection of in-stock and ready-to-ship accessories.

The Cisco 900 Series Integrated Services Routers (ISR 900) combines WAN, comprehensive security, and advanced connectivity in a compact, fanless platform. The routers are designed to provide enterprise-class security and connectivity for small to medium businesses. The ISR 921 model comes with a 4-port managed switch, providing LAN ports to connect multiple devices and up to 150 Mbps of VPN throughput for high performance. These small, yet powerful, fixed-configuration routers provide secure broadband and Metro Ethernet connectivity. The routers deliver integrated security and threat defense, protecting networks from both known and new Internet vulnerabilities and attacks.
