This is the main core of our business. Abacus started in 1996 as a system integrator company that help small businesses connect their desktops, laptops, and printers to a switch and a server. We used and still support many customers with any hardware, software, network with setup, installation, and troubleshooting issues. We install and support all Microsoft windows servers and connect offices to the internet through Cisco routers and Cisco Switches. We install and configure Dell and HP servers and connect offices together through Wide Area Network such as DSL, T1, and Virtual Private Network. We also install and setup firewalls such as Palo Alto and Cisco.
