Thursby history
Short version
Thursby has been innovating in Apple enterprise integration across three decades, introducing commercial grade capabilities years before Apple itself and much later “me too” vendors. We don't do what Apple does well, rather what it doesn't do at all, or where its implementations only cover simple use cases for end consumers rather than enterprise needs. Our support and maintenance are as important as our software since all three are required for commercial grade enterprise delivery.
Our first decade was expanding enterprise networking with minicomputers and workstations with DECnet, Ethernet and X-terminals.
Our second was growing enterprise storage integration with NFS, SMB/CIFS and DFS, along with the important addition of enterprise Active Directory policy management and login security.
Our third decade has seen the introduction of enterprise PKI and smart card security for Macs, iPads and iPhones, supporting the trends of consumerization in IT, mobile, virtualization and the cloud, following Apple's progression from workstations and latops with OS X to iOS and a wider range of devices and capabilities.
- Over 60,000 clients
- Over 1,000,000 licenses sold to-date
- Largest deals have been OEM and clients with thousands of Apple devices
- Products on the Mac for every Apple CEO
- Supporting Apple from Macintosh System Software 2 to today’s OS X Lion
- Supporting Microsoft from Windows NT 3.1 to today’s Windows Server 2008R2
- Privately owned and profitable
- One third of revenues are international with sales and support across all seven continents
- A particular appeal of our software to enterprises is its leverage of standards, not seeking to lock-in to proprietary server software
Steve Jobs commented on the value of learning from tech history in a favorite Schopenhauer short story - “He who lives to see two or three generations is like a man who sits some time in the conjurer’s booth at a fair, and witnesses the performance twice or thrice in succession. The tricks were meant to be seen only once, and when they are no longer a novelty and cease to deceive, their effect is gone.”

Since our founding we’ve delivered a mix of software and maintenance products to different end-user audiences:
- High-volume shrink-wrapped business-to-consumer, small or home office (SOHO) (B2C) products in quantities of 1, 5, 10 or 25 seats
- Significant original equipment manufacturer (OEM) solutions to well known IT companies (whose terms preclude publicity)
- Business-to-business (B2B) site licenses, each covering from 50 seats to hundreds or thousands of local, national or international Mac workstations and laptops
Delivery vehicles have ranged from jewel cases in stores such as Apple’s own and big box retailers like Fry’s and Best Buy, to national and international resellers and distribution middlemen to direct electronic downloads from the ‘net

1989 Thursby TSSnet for X-Terminals
The late 1980’s gave rise to the rapid, although short lived, appearance of X-Terminals, also known as “thin clients”. TSSnet was quickly incorporated as an OEM technology by all of the leading X-Terminal manufacturers including NCD, Tektronix, NCR, Samsung, Tandberg Data, and Wyse Technology. Other OEM relationships were also entered with Apple, Digital Equipment Corporation, EMC, Emulex Corporation, Mercury Computers, NetManage, Sequent Computers, Webster Computer Corporation, and White Pine Software.
