February 20, 2013 | About:

Headquartered in Dallas, Texas, and founded in 1998, Zix Corporation (NASDAQ:ZIXI) offers industry-leading email encryption and a unique email data leak protection solution to meet companies' data protection and compliance needs. ZIXI is trusted by the nation's most influential institutions in healthcare, finance and government for easy to use secure email solutions.

Business Quality and Capital AllocationZIXI boosts of a recurring, predictable revenue model with high renewal rates. ZIXI's email encryption services are purchased by senders based on a subscription model, either through direct and value-added reseller channels or through OEM and managed security service providers. Seventy-five percent of new customer contracts acquired through direct and value-added reseller channels are three year contracts with an average of approximately two and half years; while most sales through OEM and managed security service partners are one-year contracts with 98% to 99% of all customers completing the full length of the contract. Strong customer renewal rates result in resulting in retention of about 95% of revenue from year to year.

Its market leadership with more than 1,500 hospitals and over 1,800 financial institutions (20% of all banks and hospitals in the U.S.) using ZIXI's email encryption service, becomes a critical factor in the buying decision for companies, particularly those in the healthcare and finance sectors. ZixMobility functions across all mobile platforms and was the first to allow users on any encryption email platform to seamlessly receive encrypted email on their mobile devices. ZIXI also offers the only fully transparent email encryption services - email is encrypted without any extra steps between ZixGateway customers without any extra steps or passwords.
