Fortiva was a software as a service (SaaS) based email archiving company. Founded in 2005 by Paul Chen, the former CEO and founder of FloNetwork (later acquired by DoubleClick). Fortiva's SaaS email archiving service introduced a "hybrid" method, taking advantage of storage and services "in the cloud" while leaving control over email services at the customer site. As a result, the company claimed to offer businesses the benefits of an in-house product with the advantages of a managed solution.
Fortiva was acquired in May, 2008 by Sunnyvale, California-based security company Proofpoint, Inc.
