Since 1993, Talon Computer Consulting has architected complex solutions for small and medium businesses, local governments, school districts, enterprises, and Internet service providers — with the products and services to make the transition.
We leverage the experience gained across hundreds of engagements and pass the savings along where we can — value for both sides.
Thousands of VMs and servers installed and deployed across VMware ESXi and Hyper-V, with architecture tuned for performance and uptime.
Hundreds of Exchange servers migrated. We plan the cutover so organizations move mail platforms without losing messages along the way.
We help you maximize available technology to fully document — or better design — the systems your business depends on.
Talon offers On-Demand Support anywhere in the USA, billed at $275/hour with a one-hour minimum. Open a ticket and get a specialist, not a script.
Domain names, SSL certificates, web and email hosting — ordered directly through our hosting partner storefront.
Moving technology to the cloud is the through-line of everything we do — assessing what should move, what shouldn't, and how to get there without downtime.
Our software division was established in 1996 to write custom software for ISPs. Two products came out of it and are still in service.
An inexpensive but full-featured RADIUS server for the Windows Server platform — AAA, wireless hotspot support, and RFC compliance.
An SNMP management tool for Remote Access Servers. Gathers user session statistics across a wide range of NAS products.
A long-running reference for network engineers: subnet bits, host bits, subnet counts, hosts per subnet, and hex and dotted-decimal notation — broken out mask by mask.
